Description

The present invention relates to an image reproducing apparatus and control method thereof printing system.

  In general, an electronic imaging device such as a digital (still) camera or a digital video camera has a display device that can be used as a viewfinder at the time of photographing and as a monitor for viewing a photographed image. A liquid crystal display (LCD) is usually used as the display device. For example, as a playback method when viewing a still image, there are a method of displaying images one by one in order, a method of displaying a plurality of reduced images side by side on one screen, so-called thumbnail display.

  On the other hand, it is often pointed out that the screen size of the display device is often small due to the downsizing of the imaging device body, and is not suitable for simultaneous viewing by a large number of people. In view of this, an image pickup apparatus having a video output terminal mainly intended for viewing on a television apparatus is also common.

  Furthermore, the imaging apparatus generally has a data output terminal (interface) for outputting the captured image to an external device such as a personal computer. A so-called direct print function is also known in which an image is directly transferred to a printing apparatus using a data output terminal to perform printing. As a data output terminal (interface), a high-speed serial interface (USB (Universal Serial Bus) is typical) is often adopted.

  As described above, an electronic imaging apparatus usually has a mechanism for outputting a captured image to the outside in some form. An electronic imaging device that can select an image to be output to the outside by selecting an image displayed on a display device using an operation unit having keys, buttons, a touch panel, and the like is also known.

  With recent digital cameras with higher pixels, it is possible to shoot high-definition images, so it is now practical to magnify and view a part of the image, and there are imaging devices with such an enlarged display function. To do. Conventionally, the image output from the electronic imaging device to the external device is usually the same as the image displayed on the display device of the electronic imaging device. Therefore, when an enlarged display (display of a part of an image) is performed on the display device of the imaging apparatus, an image output to an external device such as a connected television or printer is also enlarged as in the display device of the imaging apparatus. It becomes the displayed part.

  Therefore, by using this enlarged display function, it is possible to print out only a certain area in the image. However, if you want to move the enlargement location (display part), return to the state where the entire image is displayed and select the desired enlargement location again, or use the operation unit of the imaging device, for example. The operation of moving the enlarged part is necessary and complicated. For example, in the case of using an image for a presentation, there is a scene where a specific part of the image must be shown immediately in response to a viewer's request. In such a case, this complicated operation is inconvenient.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings. In the following embodiment, a case where the present invention is applied to a digital still camera (including a camera capable of moving image shooting) will be described. However, the present invention is applied to a memory card as well as a digital video camera capable of shooting a still image. The present invention can be applied to any apparatus having a function of reproducing and displaying image data, such as a printer having a function of reading out recorded image data and displaying it.

  FIG. 1 is a diagram illustrating an example of a front appearance of a digital camera 101 according to the present embodiment, and FIG. 2 is a diagram illustrating an example of a rear appearance of the digital camera 101. The digital camera 101 includes a lens 102, a shutter button 103, a memory card storage unit 201, an LCD monitor 202, an optical viewfinder unit 203, an external output terminal unit 104, a flash unit 105, a shooting / playback changeover switch 204, and an operation button group 210. .

  The operation button group 210 includes a plurality of buttons. When switched to the playback mode by the shooting / playback switch 204, it functions as a feed button (a pair of a forward button 205 and a reverse button 206) used for image selection, which will be described later, and a confirm button 207 for confirming the selection. To do. In the shooting mode, these buttons function as shooting function switches such as shooting mode switching and continuous shooting switching.

  FIG. 3 is a diagram illustrating an external appearance example of a state in which the digital camera 101 and a color printer 301 as an example of an external device are connected. In this embodiment, the external output terminal unit 104 of the digital camera 101 conforms to the USB standard, and both are connected by a USB cable 302.

  FIG. 4 is a block diagram showing functional configurations of the digital camera 101 and the color printer 301 corresponding to the state of FIG.

  In the present embodiment, the digital camera 101 performs predetermined processing with the camera signal processing unit 401 on the video information imaged and signaled by the imaging unit 1020 including the lens 102. Thereafter, the image data is converted / compressed into an image file in JPEG2000 format by the compression / decompression circuit 402, and recorded in a memory card 404 as an example of a recording medium through processing in the recording / playback unit 403. At the time of reproduction, the recording / reproduction processing unit 403 reads the image recorded on the memory card 404, decompresses it with the compression / decompression circuit 402, and stores it in the RAM 405. The image stored in the RAM 405 is combined with the character generated by the character generator 408 and displayed on the LCD monitor 202. Further, as will be described later, it has a function of outputting an image to the printer 301 via the RAM 407, the output control unit 409, and the external output terminal unit 104. A system controller 410 controls the overall operation of the digital camera 101.

  Corresponding to the operation of the operation button group 210 feed switches 205 and 206, images recorded on the memory card 404 are sequentially read out, sequentially stored in the RAM 405, and sequentially displayed on the LCD monitor 202. Therefore, the operator can search for a desired image from the images stored in the memory card 404 by repeating the operation of the feed buttons 205 and 206 and display it on the LCD monitor 202 for viewing.

  The printer 301 includes a USB terminal 417 for connection to the digital camera 101 via the USB cable 302, an input control unit 411 that performs predetermined processing on input image data, and a RAM 412 that stores the processed data. Prepare. The print control unit 413 controls the print head 414 according to the image data while reading data from the RAM 412, and transfers the image to paper. The paper feed mechanism unit 415 feeds paper corresponding to the scan of the print head 414 based on information from the print control unit 413, and discharges the paper when printing is completed. In the printer 301, print processing is performed according to the control of the system controller 420. The operation unit 416 is provided with keys and buttons for an operator to give instructions to the printer 301, and a display device for indicating the status of the printer 301.

  Here, the characteristics of the image file in the JPEG 2000 format, which is the image recording format of the digital camera 101 in the present embodiment, will be described. JPEG2000 can realize less image deterioration and a higher compression rate than the conventional JPEG method. That is, if the image data is the same, the data size can be reduced by increasing the compression rate compared to the conventional JPEG method. In addition, it has features such as being able to cope with lossless compression and having scalability in image quality and resolution.

  Further, as a feature that is particularly noticeable in the present invention, JPEG2000 has a function called ROI (Region of Interest). ROI means a method of encoding a specific part in one image at a compression rate different from that of other parts (see Patent Document 1). As an example, let us consider a case where a presentation material in which an image portion and a character portion are mixed is compressed in the JPEG2000 format. In this case, if the image portion is encoded as an ROI (low compression rate) and a text portion that is not required to have a high resolution is encoded as a non-ROI (high compression rate), the size of the entire image can be reduced without deterioration of the image quality of the image portion. .

  The ROI is specified by the operator by, for example, specifying the desired area of the image on the operation unit before encoding, and the encoder performs compression encoding on the ROI and non-ROI areas under preset conditions. The encoded image data is generated. Mask information including information such as the position, size, and number of ROIs in the image is recorded in the header of JPEG 2000 encoded image data. By referring to the mask information, the character generator 408 can generate a frame line (described later) indicating the ROI at the time of decoding.

  FIG. 6 shows an example of an image file 601 in the JPEG2000 format. In the image, three locations 604, 605, and 606 indicated by broken lines are designated by ROI, and are encoded with higher resolution than other portions. In this example, the compression ratio of a portion of high interest such as a subject person is reduced to a high resolution, and the portion of the background that is relatively uninteresting is increased to reduce the overall data size.

  In the digital camera 101 according to the present embodiment, it is assumed that the operator can specify the ROI using the LCD monitor 202 and the operation button group 210 at the time of shooting. The compression / decompression circuit 402 performs compression encoding using the JPEG2000 system based on this designation, and the recording / playback processing unit 403 is stored in the memory card 404.

  Next, a processing procedure when the digital camera 101 according to the present embodiment outputs an image to the printer 301 that is an external device and performs printing will be described with reference to a flowchart shown in FIG.

  In this case, the digital camera 101 is set to the playback mode. In step S <b> 501, the recording / playback processing unit 403 calls an image recorded on the memory card 404 and supplies the image to the compression / decompression circuit 402 in response to the operator's send button operation. The compression / decompression processing circuit 402 decompresses the image data and stores it in the RAM 405 via the switch 406. The image data stored in the RAM 405 is combined with the character generated by the character generator 408 and displayed on the LCD monitor 202.

  At this time, when the ROI area is included in the image displayed on the LCD monitor 202, the character generator 408 generates frames 604, 605, and 606 for clearly indicating the ROI area as shown in FIG. Displayed image data.

  When the operator presses the confirm button 207, the image feed is locked. If the ROI is included in the image data, the character generator 408 further generates a ROI area selection cursor frame 603 (FIG. 6), and displays it on the LCD monitor 202 (step S502).

  If the displayed image is an image that does not have an ROI area, the image displayed on the LCD monitor 202 as a print target is confirmed when the confirm button 207 is pressed, and for example, a print procedure (data output process) is immediately started. You may do it. Here, the description of the printing process of an image having no ROI area is omitted.

  Here, a process when an ROI area is included in the confirmed image and an arbitrary ROI area is printed will be described.

  When the confirm button 207 is pressed for an image including the range designated by ROI, the feed buttons 205 and 206 function as keys for selecting one of the ROI areas included in the image being displayed. . That is, the cursor frame 603 is sequentially moved to the ROI areas 604, 605, and 606 in the image corresponding to the operation of the feed buttons 205 and 206. When the ROI areas 604, 605, and 606 are completed, the cursor frame 603 is deleted and the entire image 601 is selected.

  When the button is further operated to perform a feed operation, the cursor frame 603 appears again and “return” 607 displayed by the character is selected. When the confirm button 207 is pressed in a state where “return” 607 is selected, the image feed lock state is released, and another image is sequentially displayed by the operation of the subsequent feed button.

  By such an operation, the operator selects the ROI area to be printed out by using the cursor frame 603. Here, it is assumed that the cursor frame 603 indicates a desired ROI area, for example, this time the ROI area 604 is selected and the confirm button 207 is pressed to confirm the selected ROI area 604 as a print target. When selection confirmation of the ROI area is detected from the input of the operation unit 106 (step S503), the compression / decompression circuit 402 extracts the image data of the selected ROI area 604. Further, the switching circuit 406 is switched, and the image data of the ROI area is stored in the RAM 407 (step S505).

  On the other hand, if the confirmation button 207 is pressed in a state where “return” 607 is selected without confirming the selection of the ROI area (step S504), the screen returns to the image selection state.

  Then, the data is converted into predetermined printing data by the output control unit 409 and output from the external output terminal unit 104 which is a USB terminal (step S506). The print data is transmitted to the color printer 301 through the USB cable 302. If there is a transmission error (Yes in step S507), the process returns to step S506 to perform retransmission processing. When transmission of all data to be transmitted is completed (step S508, Yes), the process returns to step S503 to wait for the next ROI region selection confirmation (or return to image selection) for the image being displayed (step S503). S503 to S504).

  It is assumed that the entire image is selected when the confirm button 207 is pressed in a state where the entire image having the ROI is selected by the operation of moving the cursor frame 603. Then, the processes in and after step S505 are performed, and the entire image data is output to the color printer 301.

  The image data sent to the printer 301 is stored in the RAM 412 after predetermined processing is performed by the input control unit 411. The print control unit 413 controls the print head 414 according to the image data and transfers the image to paper. At the same time, the paper feed mechanism 415 is controlled based on the information from the print control unit 413, and the paper is fed in response to the scanning of the print head 414. When printing is completed, the paper is discharged and printing is completed. In this way, an image 602 is obtained as a print output of the ROI area 604.

  As described above, according to the present embodiment, it is possible to easily check and select a region designated at the time of encoding, and even when only a part of an image is to be output to an external device, the image It is possible to specify while looking at the whole.

  Therefore, even when it is desired to output a plurality of partial areas of the same image continuously, it is possible to specify without repeating the entire display and the partial display, and the operability is improved.
