Description

The present invention relates to a digital camera direct print system, and more particularly to a digital camera direct print system including a digital camera that captures an image and a printer that prints image data transferred from the digital camera.

  In recent years, ink jet printers have rapidly spread due to the beauty of photographic image quality and a decrease in price, and digital cameras have also rapidly spread due to their ease of use and a decrease in price. Images taken with a digital camera are often captured by a host computer and printed by an inkjet printer.

  Images taken with a digital camera are 2 million pixels or 4 million pixels, and each pixel is 256-level RGB data (red, green, blue), which is compressed and saved in various formats such as JPEG format. Has been. The ink jet printer records on the recording medium with two gradations of whether or not to discharge CMYK (cyan, magenta, yellow, black) ink at each grid point of a predetermined resolution. Therefore, when an image taken with a digital camera is printed with an inkjet printer via a host computer, the host computer can decompress the JPEG format, correct the image orientation (vertical or horizontal), convert the image resolution, Processing such as conversion from RGB multi-value data to CMYK binary data is performed, and then data is transferred to the ink jet printer.

  On the other hand, for users who are unfamiliar with the operation of the host computer or users who want to print more easily, a printer that can perform direct printing without going through the host computer by connecting the digital camera and inkjet printer via USB has appeared. is doing.

  In the case of this direct printing printer, a system is known in which a digital camera and a printer are connected via USB and a key on the operator panel of the printer is input to select and print an image file captured in the past with the digital camera. (For example, see Patent Document 1). In this system, a module that performs processing such as JPEG format expansion, image orientation (vertical or horizontal) correction, image resolution conversion, conversion from RGB multi-value data to CMYK binary data, etc. in the system. Is incorporated.

  By the way, some digital cameras are provided with DPOF. The “DPOF” is a function for setting in advance in what size and how many sheets are printed for each captured image. The user can print out dozens of prints at a time with a single print command if the printing contents are set in advance by the DPOF, so there is no need to wait near the printer, and other work can be performed. Can be printed while sleeping.

In addition, if the printer's battery level is insufficient for printing in a digital camera with a built-in printer, printing is not performed and only the process of storing the captured image in the printer's memory is executed. There is known an apparatus for displaying that there is an image (for example, see Patent Document 2).

  By the way, many digital cameras are driven by a battery, and when the remaining battery level is low during use of the digital camera, a warning is displayed to the user regarding charging or connection of the AC adapter.

  Also, there is a battery-powered printer, and, like a digital camera, when the remaining battery level is low, a warning is displayed to the user to charge or connect an AC adapter.

  Therefore, when dozens of sheets are printed at a time with the DPOF setting, when starting printing, even if there is still a remaining battery level, in the process of printing dozens of sheets, The printer battery level may be low.

  When the battery level is low, printing is automatically interrupted, and charging or AC adapter connection is displayed as a warning to the user. When the user is not nearby, it cannot be handled. Will result in a stop on the way.

  The only way to avoid this is to connect the AC adapter before starting printing, regardless of the remaining battery level.

  That is, in the above conventional example, when printing is performed with a battery-powered digital camera or printer, there is a problem that the user cannot print with confidence without worrying about running out of the battery.

  Next, the flow of print processing by the digital camera 10 will be described.

  FIG. 3 is a flowchart illustrating the flow of printing processing by the digital camera 10 in the first embodiment.

  When the printing process is started, the digital camera 10 first causes the user to specify an image to be printed, a paper size, and the number of sheets in S1. In S2, the number of pixels of the image to be printed, the paper size, and the number of sheets are designated, and the printer 20 is requested for an estimated printing time.

  In S3, the printer 20 waits for reception of a print time estimated value. In S4, the received estimated printing time value is compared with the remaining battery time of the digital camera 10, and if the estimated printing time value is less than or equal to the remaining battery time of the digital camera 10, the process proceeds to S6. Proceed to

  In step S5, a battery shortage error is displayed, and the process is terminated. In step S6, the printer 20 is instructed to start printing. In step S7, the printer 20 waits for the completion of printing. In step S8, the printing completion is displayed. The process is terminated.

  FIG. 4 is a flowchart illustrating the flow of the printing process of the inkjet printer 20 in the first embodiment.

  When the printing process is started in response to an instruction from the digital camera 10, the inkjet printer 20 waits for a request from the digital camera 10 in S11. In S12, the type of the received request is checked, and a request for an estimated print time is received. If there is, the process proceeds to S13, and if it is a request to start printing, the process proceeds to S15.

  A method for obtaining the estimated printing time from the number of pixels of the image to be printed, the paper size, and the number of sheets in S13 and calculating the estimated printing time will be described in detail later.

  In S14, the estimated print time estimated value is returned to the digital camera 10, and the process returns to S11. In step S15, the designated image is printed. In step S16, the completion of printing is notified to the digital camera 10, and the process ends.

  Next, in the first embodiment, a method for calculating the estimated printing time (S13) will be described in detail.

  FIG. 5 is a diagram illustrating a printing time estimation table in the first embodiment.

  The printing time of the inkjet printer 20 differs depending on the performance of the printer 20, the paper size of the image to be printed, and the number of pixels. Therefore, the printing time T (P, S) at each pixel number (P) and each paper size (S) is measured in advance, and a table as shown in FIG. 5 is created.

  For example, if it takes 95 seconds to print an image with 2M (2 mega = 2 million) pixels in L size, 95 is placed in the corresponding location T (2M, L size) in the print time estimation table. Write with seconds. In this way, all the tables are filled and the completed product is stored in the ROM 22 in advance.

  FIG. 6 is a diagram for explaining a method for calculating the estimated printing time.

  Assuming that the number of pixels of the image number i (i = 1, 2,..., N) to be printed is Pi and the paper size is Si, the estimated print time of this image is T ( Pi, Si). Therefore, the estimated printing time T_all of all images is obtained as the sum of T (Pi, Si) as shown in the figure. In S13, the estimated printing time is calculated in this way.

  FIG. 7 is a time chart illustrating the direct print process according to the first embodiment.

  Here, it is assumed that the battery level of the digital camera 10 is sufficiently left.

  In S23, reception from the printer 20 is waited. In S24, it is determined whether or not the received content is a battery shortage error of the printer 20, and if it is a battery shortage error of the printer 20, the process proceeds to S25. Otherwise, the process proceeds to S26.

  In S25, a printer battery shortage error is displayed, and the process ends.

  In S26, the received estimated print time value is compared with the remaining battery time of the digital camera 10. If the estimated print time value is equal to or less than the remaining battery time of the digital camera 10, the process proceeds to S28. In S27, a battery shortage error is displayed and the process ends.

  In step S28, the printer 20 is instructed to start printing. In step S29, the printer 20 waits for reception of the completion of printing. In step S30, the printing completion is displayed, and the process ends.

  FIG. 10 is a flowchart illustrating the flow of the printing process of the inkjet printer 20 in the second embodiment.

  In the second embodiment, when the printing process is started by an instruction from the digital camera 10, the inkjet printer 20 waits for a request from the digital camera 10 in S41, checks the type of the received request in S42, and prints the print time. If it is a request for an estimated value, the process proceeds to S43, and if it is a request to start printing, the process proceeds to S47.

  In S43, the estimated printing time is obtained from the number of pixels of the image to be printed, the paper size, and the number of sheets. The calculation method is the same as the calculation method in the first embodiment. In S44, the calculated print time estimated value is compared with the remaining battery time of the printer 20. If the estimated print time is equal to or less than the remaining battery time of the printer 20, the process proceeds to S45. Otherwise, the process proceeds to S46. .

  In S45, the calculated print time estimated value is returned to the digital camera 10, and the process returns to S41.

  In S46, a printer battery shortage error is notified to the digital camera 10, and the process returns to S41.
