Description

Data viewer type webcam for online classes

The present invention relates to a real camera type webcam for online classes, and more particularly, to a real imager type webcam for online classes capable of capturing and transmitting images of various angles by finely adjusting the camera angle.

In general, a real imager is a device that receives various kinds of real images and transmits images to peripheral devices, and is widely used as auxiliary equipment for lectures with various additional functions.

In a conventional real imager, a vertical member is installed upright on a support arm, a horizontal member extending in a horizontal direction is connected to the vertical member, and a camera for photographing an object is provided on the horizontal member.

These real presenters have various functions, such as magnifying objects through programs installed in personal PCs, by capturing and transmitting objects or documents seen in the camera provided in the real imager to a personal PC while connected to an office or classroom through a local network. is configured to implement

On the other hand, a conventional webcam has been manufactured and used for the purpose of having a conversation while mainly looking at a user's own face with a counterpart while connected to an online network.

The camera of the webcam is limited to the purpose of viewing the other person's face, and is mounted with the lens part facing the front direction, and is configured to take images of users taking video lectures and classes.

Recently, teachers and students remotely place webcams on their personal PCs in classrooms and at home, and transmit images through the webcam in real time, so that they can have a face-to-face conversation with each other.

Since such a conventional webcam is configured to mainly illuminate the front, it was a photographing structure that could not confirm the student's desk or keyboard side. Accordingly, there was a problem in that it was difficult for the teacher to see the student's face in various fields of view except for the student's face, so it was difficult to check the student's abnormal behavior outside the class and the state of participation.

Moreover, when a user uses a webcam to illuminate a document such as a textbook on a desk, the document is output and transmitted in an inverted image, which is quite inconvenient to check the document with another user.
