Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
Referring to fig. 1-2, an embodiment of the present application provides an image capturing method. The image acquisition method is used for the electronic device 100, and comprises the following steps:
s10, acquiring an image output by the image sensor as a pre-processing image in the process of shooting by the electronic device 100;
s20, processing the preprocessed image to obtain a video;
and S30, acquiring the preprocessed image corresponding to the snapshot instruction according to the snapshot instruction and using the preprocessed image as the snapshot image, wherein the resolution of the snapshot image is greater than that of the video.
The electronic device 100 of the embodiment of the present application includes a memory and a processor 101, and the above steps S10-S30 can be executed by the processor 101, or the processor 101 is configured to acquire an image output by the image sensor and serve as a pre-processed image during the process of capturing an image by the electronic device 100; and for processing the pre-processed image to obtain a video; and the pre-processing image corresponding to the snapshot instruction is obtained according to the snapshot instruction and is used as a snapshot image, and the resolution of the snapshot image is greater than that of the video.
In the image acquisition method and the electronic device 100 in the embodiment of the application, in the process of shooting by the electronic device 100, the snapshot image is acquired from the preprocessed image according to the snapshot instruction, and the resolution of the snapshot image is greater than that of the video, so that the acquisition process of the snapshot image is convenient, the resolution of the snapshot image is higher, and the user requirements are met.
Specifically, the electronic apparatus 100 may be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic apparatus 100 may be a mobile phone, a portable game device, a laptop computer, a Personal Digital Assistant (PDA), a portable internet device, a wearable device, a vehicle-mounted terminal, a navigator, a music player, a data storage device, and the like.
Note that, for convenience of description, the image capturing method of the electronic device 100 according to the embodiment of the present application is explained by taking the electronic device 100 as a mobile phone. This is not intended to limit the specific form of the electronic device 100.
In the related art, in order to obtain an image at a certain moment, a user often needs to play a video in a shooting process, and when the video is played to a moment required by the user, the user captures the image through a screen capturing operation, so that the operation is troublesome.
In order to improve the convenience of the snapshot operation, a button may be set on the display screen during the process of shooting the video by the electronic device 100, and when the user encounters a desired photo, the button on the display screen may be pressed, so that the photo is saved. However, whether the picture is obtained by screen capture during video playing or the picture is obtained by shooting video, the resolution of the pictures obtained by the two modes is the same according to the resolution of the video, and the resolution is lower.
In the application, the snapshot image is acquired in the process of shooting by the electronic device 100, so that the acquisition process of the snapshot image is simpler and more convenient; in addition, the snapshot image is obtained according to the preprocessed image output by the image sensor, and is not obtained according to the image in the video, so that the resolution of the snapshot image is larger than that of the video, and the image with higher resolution and better definition can be obtained.
In step S10, the electronic device 100 may start the related application program camera shooting, for example, a "camera" application program camera shooting of the electronic device 100 may be turned on to obtain a video. During the shooting process of the electronic device 100, the image sensor may perform full-scale exposure to obtain an original image, and the original image may be output after performing a cropping and scaling (down) operation inside the image sensor, so as to obtain a preprocessed image. The resolution of the preprocessed image is, for example, 3840 × 2160.
In step S20, since the pre-processed image is generally in units of frames and the format of the pre-processed image is different from that of the video, the pre-processed image can be processed by means of encoding, image reduction, or the like to obtain the video. The resolution of the video is, for example, 1080 × 720(720P) or 1920 × 1080(1080P) resolution.
In step S30, a snapshot instruction may be formed according to a user trigger. For example, a snapshot key is arranged on a display screen of the electronic device 100, and after a user clicks the snapshot key in the process of shooting, the display screen is triggered to form a snapshot instruction. As another example, the electronic device 100 may be provided with a physical key to trigger the formation of the snapshot instruction through the physical key.
The generation timing of the snapshot image is substantially the same as the generation timing of the snapshot command. The snapshot image can be a frame of preprocessing image or a plurality of frames of preprocessing images. When the snapshot image is a multi-frame image, a multi-frame continuous preprocessed image corresponding to the generation time of the snapshot instruction can be used as the snapshot image.
In one example, as discussed above, the video may be obtained by downscaling (downscaling) the pre-processed image, so that the resolution of the video is smaller than that of the pre-processed image, and the resolution of the snapshot image is the same as that of the pre-processed image, so that the resolution of the snapshot image is greater than that of the video. For example, the resolution of a snap-shot image is 3840 × 2160, and the resolution of a video is 1920 × 1080.
In the embodiment of the present application, the preprocessed image may be stored in an image buffer of the electronic device 100.
Referring to fig. 3, in some embodiments, step S20 includes the steps of:
s21, reducing the preprocessed image;
and S22, carrying out video coding on the reduced preprocessed image to obtain a video, wherein the resolution of the video is smaller than that of the preprocessed image.
In some embodiments, steps S21 and S22 may be performed by the processor 101, or the processor 101 may be configured to reduce the pre-processed image; and the video coding unit is used for carrying out video coding on the reduced preprocessed image to obtain a video, and the resolution of the video is smaller than that of the preprocessed image.
In this way, after the pre-processed image is reduced and encoded, a video meeting the expectation can be obtained, so that the video can be normally played in the electronic device 100.
In step S21, the resolution of the pre-processed image may be reduced, so that the pre-processed image is reduced to reduce the resolution of the video and reduce the storage space occupied by the video. For example, a preprocessed image having a resolution of 3840 × 2160 is reduced to obtain an image having a resolution of 1920 × 1080.
In step S22, the preprocessed image is encoded to obtain a video in MP4, AVI, or other formats, so that the video meets the video format requirement of the electronic device 100, and the electronic device 100 can normally play the video after capturing the video.
Referring to fig. 4, in some embodiments, the image capturing method includes the steps of:
s01, controlling the image sensor to output a plurality of frames of first preprocessed images;
s02, controlling the image sensor to output a frame of second pre-processing image according to the snapshot instruction, wherein the resolution of the second pre-processing image is greater than that of the first pre-processing image, and the pre-processing image comprises the first pre-processing image and the second pre-processing image;
step S20 includes the steps of:
and S23, processing the first preprocessed image and the second preprocessed image of the plurality of frames to obtain a video, wherein the resolution of the video is the same as that of the first preprocessed image.
Step S30 includes the steps of:
and S31, taking the second preprocessed image as a snapshot image according to the snapshot instruction.
In some embodiments, steps S01-02, S23, S31 may be executed by the processor 101, or the processor 101 is configured to control the image sensor to output a plurality of frames of the first pre-processed image; the image sensor is controlled to output a frame of second pre-processing image according to the snapshot instruction, the resolution of the second pre-processing image is greater than that of the first pre-processing image, and the pre-processing image comprises the first pre-processing image and the second pre-processing image; the system comprises a first preprocessing image, a second preprocessing image, a video processing unit and a display unit, wherein the first preprocessing image and the second preprocessing image are used for processing a plurality of frames of the first preprocessing image and the second preprocessing image to obtain a video, and the resolution of the video is the same as that of the first preprocessing image; and the second preprocessing image is used as a snapshot image according to the snapshot instruction.
It can be understood that if the resolution of the image output by the image sensor is high, the amount of data transmitted by the electronic device 100 becomes large, and the frame rate of the obtained video is low, which results in a poor image capturing experience. In the embodiment, when no snapshot instruction exists, the image sensor outputs more first preprocessed images with lower resolution, so that the frame rate of the images output by the image sensor can be improved, and the frame rate of the processed videos is ensured; when the snapshot instruction is obtained, the image sensor outputs a second preprocessed image with higher resolution, and the higher resolution of the snapshot image is ensured.
Specifically, in step S01, after the image sensor is exposed to full size to obtain the original image, the original image may be cropped and reduced inside the image sensor to output the image, so as to obtain the first pre-processed image with lower resolution, and since the resolution of the first pre-processed image is the same as the resolution of the video, the processor 101 does not need to perform cropping, reduction and other processing on the first pre-processed image, so that the amount of data processed by the processor 101 is reduced, and the power consumption of the processor 101 is further reduced. The resolution of the first preprocessed image is 1920 × 1080, for example.
In step S02, the resolution of the second preprocessed image is higher, and the resolution of the resulting snap-shot image is also higher. Note that the second preprocessed image may be formed by subjecting an original image obtained by exposing the image sensor to a process such as cropping and reduction.
In step S23, it is understood that the first pre-processed image and the second pre-processed image are images that are continuously output by the image sensor, and thus, processing the first pre-processed image and the second pre-processed image can ensure that the video is continuous without missing frames. In addition, since the resolution of the second pre-processed image is greater than the resolution of the first pre-processed image, and the resolution of the video is the same as the resolution of the first pre-processed image, in the process of processing the second pre-processed image, the second pre-processed image may be subjected to processing such as cropping and reduction so that the resolution of the processed second pre-processed image is the same as the resolution of the first pre-processed image. In addition, the second preprocessed image is used as the snapshot image, and the processing of the second preprocessed image further comprises a mode of copying the second preprocessed image, and the copied image is used for forming a video.
In step S31, in one example, the second pre-processed image just output by the image sensor may be copied to obtain a second pre-processed image, that is, the number of the second processed images may be two, wherein one of the second processed images is used for processing to form a video and the other second processed image is used as a snapshot image.
Referring to fig. 5, in some embodiments, the image capturing method includes the steps of:
s03, controlling the image sensor to output a first preprocessed image;
s04, controlling the image sensor to output a frame of second pre-processing image every other predetermined frame of image, wherein the resolution of the second pre-processing image is greater than that of the first pre-processing image, and the pre-processing image comprises the first pre-processing image and the second pre-processing image;
step S20 includes the steps of:
s24, processing a plurality of frames of the first pre-processed image and the second pre-processed image to obtain a video, wherein the resolution of the video is the same as that of the first pre-processed image;
step S30 includes the steps of:
s32, acquiring the generation time of the snapshot instruction;
s33, the second preprocessed image of one frame corresponding to the generation time is used as the snapshot image.
In some embodiments, steps S03-S04, S24, S32 may be performed by the processor 101, or the processor 101 is configured to control the image sensor to output the first pre-processed image; the image sensor is controlled to output a frame of second pre-processing image every other predetermined frame of image, the resolution of the second pre-processing image is greater than that of the first pre-processing image, and the pre-processing image comprises the first pre-processing image and the second pre-processing image; the system comprises a first preprocessing image, a second preprocessing image, a video processing unit and a display unit, wherein the first preprocessing image and the second preprocessing image are used for processing a plurality of frames of the first preprocessing image and the second preprocessing image to obtain a video, and the resolution of the video is the same as that of the first preprocessing image; the generation time for acquiring the snapshot instruction is obtained; and the image processing device is used for taking the second preprocessed image of one frame corresponding to the generation moment as the snapshot image.
It can be understood that there may be a certain time in the process of generating and transmitting the snapshot instruction to the response, for example, there is a time delay from when the user clicks the display screen to generate the snapshot instruction to when the snapshot image is formed in response to the snapshot instruction, and if the time delay is long, the image pre-obtained by the user is inconsistent with the snapshot image, and there is a certain frame rate difference.
In the embodiment, the image sensor outputs the pre-processed image with two resolutions, so that the frame rate of the image output by the image sensor can be ensured, and the frame rate of the video obtained after processing can be ensured. In addition, due to the fact that the second preprocessing is output discontinuously, one frame of second preprocessed image can be determined to be used as the snapshot image from the multiple frames of second preprocessed images according to the generation time of the snapshot instruction, and therefore the problem of snapshot delay can be solved.
Specifically, in step S03, after the image sensor is exposed to full size to obtain the original image, the original image may be cropped and reduced inside the image sensor to output the image, so as to obtain the first pre-processed image with lower resolution, and since the resolution of the first pre-processed image is the same as the resolution of the video, the processor 101 does not need to perform cropping, reduction and other processing on the first pre-processed image, so that the amount of data processed by the processor 101 is reduced, and the power consumption of the processor 101 is further reduced. The resolution of the first preprocessed image is 1920 × 1080, for example.
In step S04, the resolution of the second preprocessed image is higher, and the resolution of the resulting snap-shot image is also higher. Note that the second preprocessed image may be formed by subjecting an original image obtained by exposing the image sensor to a process such as cropping and reduction. The first pre-processed image may be output every other frame, two frames, and then one frame of the second pre-processed image.
In step S24, it is understood that the first pre-processed image and the second pre-processed image are images that are continuously output by the image sensor, and thus, processing the first pre-processed image and the second pre-processed image can ensure that the video is continuous without missing frames. In addition, since the resolution of the second pre-processed image is greater than the resolution of the first pre-processed image, and the resolution of the video is the same as the resolution of the first pre-processed image, in the process of processing the second pre-processed image, the second pre-processed image may be subjected to processing such as cropping and reduction so that the resolution of the processed second pre-processed image is the same as the resolution of the first pre-processed image. In addition, as the second preprocessed image of one frame is taken as the snapshot image, the processing of the second preprocessed image also comprises the mode of copying the second preprocessed image, and the copied image is used for forming a video.
After acquiring the time at which the snapshot instruction is generated, frames may be taken forward in steps S32 and S33, so that the corresponding second preprocessed image is obtained as the snapshot image.
Referring to fig. 6, in some embodiments, step S33 includes:
s331, acquiring the time required by the snapshot instruction from generation to the image sensor;
and S332, acquiring a second preprocessed image corresponding to the generation moment according to the required time, and taking the second preprocessed image as a snapshot image.
In some embodiments, steps S331-S332 may be performed by the processor 101, or the processor 101 may be configured to obtain a time required for the snapshot instruction to be generated and transmitted to the image sensor; and the second preprocessing image corresponding to the generation moment is acquired according to the required time and is used as a snapshot image.
Therefore, the snapshot image corresponding to the snapshot instruction can be accurately obtained, and the user experience is improved. In one example, the time required for the snapshot command to be transmitted in the electronic device may be obtained experimentally, and a better relationship between the snapshot command and the snapshot image may be obtained by continuously correcting the snapshot command generation time and obtaining the snapshot image.
The embodiment of the application also provides a computer readable storage medium.
