  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a block diagram illustrating the main functions of the digital camera 1 of the present invention.

The image capturing unit 101 that captures a subject includes a photographing lens, a diaphragm, a shutter, an image sensor, a driver that drives the image sensor, and the like. Here, the image pickup device is a photoelectric conversion image pickup device that outputs an electric signal corresponding to the light intensity of the subject image formed on the image pickup surface, and a CCD type or MOS type solid state image pickup device is used. An imaging signal from the imaging unit is converted into a digital signal by the A / D converter 102 and temporarily stored in the buffer memory 103. The buffer memory can store a plurality of frames of image data captured by the imaging unit 101 at the same time. The imaging signal is subjected to processing such as contour enhancement, gamma correction, color correction, and compression / expansion processing during recording / reproduction in accordance with instructions from the CPU 104. The signal after this processing is also temporarily stored in the buffer memory 103 described above. If necessary, the image data compressed by the processing circuit 105 is recorded on a memory card 106 that is detachably attached to the digital camera. Image data captured by the imaging unit 101 and converted into a digital signal is displayed on a liquid crystal (LCD) monitor 107. The LCD monitor 107 is also used to reproduce and display image data recorded on the memory card 106. The captured or reproduced image data is also sent to an external display device through the interface unit 108. As a connection method with the display device when transmitting the image data, there are a connection method using a cable such as USB or IEEE1394, or a wireless connection method such as a wireless LAN or Bluetooth. In the present embodiment, it is assumed that the digital camera and various electrical appliances such as a TV monitor placed in each room in the home are connected to each other via a home network via a wireless LAN. Among these electrical appliances, devices that are turned on can detect IDs (identification information) of devices that are turned on, and can transmit and receive data in accordance with preset operation procedures. If a plurality of devices are detected at this time, a device that transmits and receives data is selected according to a predetermined priority order. The operation member 109 includes a shutter button or the like for instructing start of photographing, and details will be described later with reference to FIG. The CPU 104 controls the entire sequence at the time of shooting and playback of the digital camera 1. The CPU 104 further includes a counter 1041 that measures an elapsed time after selecting one image when reproducing image data. Details of this function will be described later.

  An example of the display form in each device when the digital camera 1 and the external large display device 2 according to the present invention are connected will be described with reference to FIG. 2 that are the same as in FIG. 1 are numbered the same. An external large display device (external monitor) 2 is a home TV monitor or TV receiver having a large display screen 201. In addition to receiving ordinary TV broadcast programs, this TV receiver directly receives data from the digital camera 1 by the reception antenna 202 using a wireless LAN protocol. Or the management server which manages the whole home network may be installed separately, and the form which transmits / receives various data between apparatuses via this server may be sufficient.

  The external part of the digital camera 1 will be described. The aforementioned operation member 109 is composed of at least buttons 1091 to 1095. Reference numeral 1091 denotes a shutter button for instructing start of photographing. Reference numeral 1092 denotes a select dial for switching between recording and reproduction modes. A multi-selector 1093 is used to move the cursor up / down / left / right with respect to various menu items displayed on the LCD monitor 107 by pressing a menu display button 1094, and to set and determine menu displayed items and functions. It is. The multi-selector 1093 is also used for raising and lowering the zoom lens at the time of shooting, and is also used for updating a reproduced image, selecting a screen in the multi-display screen, and zooming up and down the reproduced screen during reproduction. Reference numeral 1095 denotes a multi-display switching button for switching whether to reproduce a multi-screen or only one screen on the LCD monitor. Reference numeral 1061 denotes an insertion slot for the memory card 106. Reference numeral 1081 denotes an antenna that transmits various data to an external monitor using a wireless LAN protocol. As an embodiment of the present invention, in FIG. 2, an image surrounded by a bold frame at the lower right of the reduced images of four frames displayed on the LCD monitor 107 (an image in which frame number 4 is displayed in the figure). ) Is selected, and the data of the selected image is sent to the TV monitor 2 and displayed on the large screen 201.

Next, the operation of the present invention will be described using the flowcharts of FIGS. FIG. 3 is a schematic operation flow of the entire digital camera 1 according to the present invention connected to the external monitor 2. In step S11, it is confirmed whether the power of the digital camera 1 is turned on. If the power is turned on, the process proceeds to step S12 to check whether the digital camera 1 is connected to the external monitor 2 by recognizing the identification information described above. . Here, the connection form may be either the above-described wired or wireless method. If not, the process proceeds to step S13 to check whether the power is turned off. If the power is turned off, the process is terminated. If not, the process returns to step S12 to check whether the external monitor 2 is connected. In the middle of the loop of step S12 and step S13 when the external monitor 2 is not connected, the digital camera alone performs shooting or playback operations, but these are not necessary for the description of the present invention and are omitted here. ing.

  If it is confirmed in step S12 that the external monitor 2 is connected, the process proceeds to step S14 where the number of horizontal / vertical pixels and the aspect ratio of the display unit 201 of the external monitor 2 are changed from the external monitor 2 connected here. For example, information on the external monitor 2 is read. In step S15, the selection dial 1092 determines whether or not the playback mode is set. If the shooting mode is set, the process proceeds to step S16 to perform a shooting operation. If the playback mode is set, the process proceeds to step S17 to set the display mode of the multi-screen and selection screen on the LCD monitor 107 and the external monitor 2 in the playback mode. The specific contents of this display form will be described in step S18. To switch the display on the LCD monitor 107 from single-screen playback to multi-display playback among the display modes, the multi-display switching button 1095 is pressed to switch the display screen alternately between single-screen playback and multi-display playback. The other display modes are set by pressing the menu display button 1094 and selecting a selection menu (contents will be described later in step S109) with the multi selector 1093.

  In step S18, a playback image is displayed on the LCD monitor 107 or predetermined screen data is output to the external monitor 2 in accordance with the display mode in the playback mode set in step S17. Details of the monitor reproduction in step S18 will be described with reference to FIGS. In step S19, it is determined whether the power of the digital camera 1 has been turned off. If it is not turned off, the process returns to step S15, and if it is turned off, this flow is terminated.

  The monitor reproduction in step S18 in FIG. 3 will be described with reference to FIGS. First, in step S101 in FIG. 4, it is determined whether or not the multi-display switching button 1095 is pressed as described above to set the multi-display on the LCD monitor 107. If it is set to display multiple images, four images are displayed on the LCD monitor 107 as shown in FIG. 2, and the process proceeds to step S109 in FIG. In this case, the number of images to be displayed in a multi display mode can be set to other image numbers such as 9 images by the multi selector 1093.

If it is not set to display multiple images, the process proceeds to step S102, the counter 1041 described in FIG. 1 is reset, and the last image recorded on the memory card 106 is displayed on the LCD monitor 107 in step S103. Display on the screen. In step S104, it is determined whether or not a predetermined time has elapsed since the display of one screen was started after the counter 1041 was reset. If the predetermined time has not elapsed, the process proceeds to step S106. If the predetermined time has elapsed, the process proceeds to step S105, and the same screen as that displayed on the LCD monitor 107 is displayed on the external monitor 2. Image data is sent out. In step S106, it is determined whether or not an operation for selecting the next screen has been performed. For this selection, the UP / DOWN function of the multi-selector 1093 is used. If the next screen is selected, the process returns to step S102 to reset the counter 1041. If the next screen is not selected, the process proceeds to step S107, where it is determined again whether or not the multi-display is set on the LCD monitor 107. If multi-display is set here, the process proceeds to step S109 in FIG. 5, and if it is determined that multi-display is not set, the process proceeds to step S108. In step S108, it is determined whether or not the selection dial 1092 is set to a mode other than the playback mode. If the playback mode is subsequently set, the process returns to step S103 to continuously display the image selected and displayed so far on the LCD monitor 107. If it is determined in step S108 that the reproduction mode has been completed, this flow ends.

  In this way, on the LCD monitor 107 of the digital camera 1, reproduced images for each screen are displayed one after another in response to the UP / DOWN operation of the multi-selector 1093, whereas on the large screen 201 of the external monitor 2. Even if the next screen is selected within a predetermined period set in advance, this screen is not displayed. This display mode will be described with reference to FIG. The upper part of FIG. 8 shows the timing of image display on the LCD monitor 107. The lower part shows the display screen on the external monitor. In this figure, the screen A starts to be displayed on the external monitor 2 after a certain period (T) has elapsed since the screen A was selected. After that, after selecting the screens B and C, the screen of A continues to be displayed since a certain period has not elapsed. After that, the screen display is changed from A to D for the first time after a certain period of time after selecting the screen D. Thereby, it is possible to prevent the external monitor 2 from being unsightly due to the change and display of the playback screen one after another. In addition, since image data that is not actually displayed is not transmitted, camera operation and network line use are performed efficiently. Here, the fixed time is about 0.5 seconds, but it is better to be able to change this value according to the user. The change can be easily set by the menu display button 1094 and the multi-selector 1093 described above.

  If it is determined in step S101 or step S107 that the display has been switched to the multi display by the multi display switch button 1095, the process proceeds to step S109 in FIG. Here, the same multi-screen as the multi-screen displayed on the LCD monitor 107 is output to the external monitor 2 or only a single image selected from the multi-screen displayed on the LCD monitor 107 is displayed on the external monitor 2. It is determined whether it is set to output to. For this setting, an item of external monitor output screen selection is selected from the selection menu items displayed by pressing the menu display button 1094 (not shown). After the selection, two items of multi-screen output and selected image output are displayed (not shown), and the setting is made by selecting one of these items. A multi-selector 1093 is used for selection. Among these, if it is set to output the selected image, the process proceeds to step S115, and if it is set to output the multi-screen, the process proceeds to step S110. In step S110, in order to display a multi-screen on the LCD monitor 107 and the external monitor 2, multi-screen data for each display screen is created. Details of step S110 will be described later with reference to FIG. In step S111, it is determined whether an instruction to update the displayed LCD monitor 107 or multi-screen of the external monitor 2 has been issued. As an example of a method for updating the multi-screen, a multi-selector 1093 shown in FIG. 2 is used to select an image selection cursor displayed in the multi-screen (in the case of FIG. 2, the frame of frame number 4 is enclosed). New 4 images or 9 images are displayed by moving the same thick frame) to the upper left or lower right and moving it in the same direction. When an update instruction is issued in this way, the process returns to step S110 to display a multi-screen on the LCD monitor 107 or the external monitor 2. If no update instruction is given in step S111, it is determined in step S112 whether or not the display has been changed to the single screen display setting by the multi-display switching button 1095. If the multi-display setting is maintained, the process returns to step S109. If it is determined that the setting is changed so as to make the single display, the process proceeds to step S113, where it is determined whether the LCD monitor 107 is turned off. This will be described in the detailed description of step S110 in FIG. 7 because the LCD monitor 107 may be turned off. If it is off, the LCD monitor 107 is turned on in step S114, and if it is on, the process directly returns to step S102 in FIG.

If it is set in step S109 to output only one image selected from the multi-screen to the external TV monitor 2, the process proceeds to step S115 in FIG. 6 to create a multi-screen for display on the LCD monitor 107. In step S116, a cursor for selecting a predetermined image is superimposed on the created multi-screen and displayed on the LCD monitor 107. FIG. 2 shows an example of this display. Originally, in the first screen displayed on the multi-screen, the upper left image of the reduced image (frame number 1 in this figure) is surrounded by a thick cursor to indicate that it is selected. In FIG. 2, the multi-selector 1093 is selected. Shows the case where the frame number 4 is selected. Step S117 The counter 1041 is reset as in step S102. In step S118, it is determined whether or not the image surrounded by the selected thick cursor remains selected for a certain period. Again, for the same reason as when the fixed period has elapsed in step S104, if the fixed period has not elapsed, the process proceeds to step S120, and if the fixed period has elapsed, the process proceeds to step S119 to select the image selected by the cursor. Are output to the external monitor 2. In step S120, it is determined whether or not the next image has been selected by the multi selector 1093. If it is selected, the process returns to step S116 to display a multi-screen with different cursor positions. If the next screen has not been selected, the process proceeds to step S121, where it is determined whether an instruction to update the multi-screen has been issued.

  If an update instruction is given, the process returns to step S115 to create a new multi-screen for the LCD monitor 107. If no update instruction has been given, the process proceeds to step S122, where it is determined again whether or not the image data selected by the cursor is set to be output to the external monitor 2, as in step S109 described above. If the setting has been changed so that the multi-screen is output, the process returns to step S110 to proceed to a sequence for outputting the multi-screen to the external monitor 2, and if the setting has not been changed, the process proceeds to step S123. In this step S123, it is determined whether or not the multi-display setting of the LCD monitor 107 so far has been changed. If the setting has been changed, the process returns to step S102, which is a single screen display flow. If the setting has not been changed, the process proceeds to step S124, where it is determined whether or not the reproduction mode is terminated. If it is determined that the reproduction has been completed, the present flow is ended. If not, the flow returns to step S118 to repeat the flow for outputting the selected image to the external monitor 2.

  With the sequence described so far, the LCD monitor 107 can display multiple images, and the external monitor 2 can display only a single image selected from the reduced images displayed on the LCD monitor 107 on the large external screen. . This makes it easy to check what other images are recorded on the LCD monitor of the digital camera even when one image is displayed on a large screen on an external monitor. You can search with the camera. Also in this case, if the cursor is moved in order to select another image in a short time, the image selected before moving the cursor is not output to the external monitor 2. In the case of a digital camera capable of recording moving images, when a moving image and a representative screen indicating the contents of the moving image and character data indicating the recorded contents are simultaneously recorded on the memory card 106, the representative screen or character data is displayed on the LCD monitor 107. It is also possible to display the selected moving image on the external monitor 2 in a list.

  Next, creation and output of a multi-screen of the LCD monitor 107 and the external monitor 2 in step S110 of FIG. 5 will be described with reference to FIG. In step S130, it is determined whether or not the same multi-screen data as the multi-screen displayed on the LCD monitor 107 is set to be output to the external monitor 2. This setting can be set in advance using the menu display button 1094 and the multi-selector 1093, but may be set in advance to any one by default. If it is set to output the same multi-screen as the display on the LCD monitor 107 to the external monitor 2, the process proceeds to step S131, and if not, the process proceeds to step S132. In step S132, the number of horizontal and vertical pixels of the connected external monitor 2 is determined from the external monitor information read in step S14 of FIG. In step S133, the arrangement and the number of reduced images in the multi-screen to be displayed on the large screen 201 of the external monitor 2 are determined according to the determined number of pixels.

  In step S134, it is determined whether the arrangement or the number of images determined in step S133 is different from that displayed on the LCD monitor 107. If they are the same, the process proceeds to step S131, and if they are different, the process proceeds to step S135. In step S135, it is determined whether the LCD monitor 107 is on. If it is on, the display contents are different between the LCD monitor 107 and the external monitor 3, so that the user is confused when selecting an image with the multi-selector 1093 of the digital camera 1. In order to avoid this, the display of the LCD monitor 107 is turned off, and multi-screen data for the external monitor 2 is output in step S137. If the screens of the LCD monitor 107 and the external monitor 2 are the same multi-screen in step S134, the process proceeds to step S131 to create a multi-screen for the LCD monitor 107 and to the external monitor 2 in step S138. The same multi-screen data as the multi-screen displayed at 107 is output.

  FIG. 8 shows a display example of the multi-screen described so far. In FIG. 8, the digital camera 1 is the same as the digital camera described in FIG. The external monitor 3 is a horizontally long large screen monitor such as a high-definition television or the like which is different from the external monitor 2 of FIG. Based on the number of vertical and horizontal pixels of the external monitor 3, the digital camera 1 displays 4 × 3 images as shown in FIG. 2, whereas the LCD monitor 107 displays 2 × 3 images as shown in FIG. doing. Further, the LCD monitor 107 on the digital camera side originally displays a reduced image of 4 images as a multi-display as shown in FIG. 2, but when the external monitor 3 is connected, the external monitor 3 is connected as shown in FIG. On the other hand, image data for six screens is transmitted and its own LCD monitor 107 is turned off. In this way, when the number of multi-screen images displayed on the external monitor is different from the number of images displayed on the LCD monitor of the digital camera, it is natural that the display arrangement of these images is changed. The sequence may change even if it does not change. For example, this is the case when a portrait screen of a mobile phone is desired to be displayed on a landscape screen such as a normal external TV monitor. In this case as well, the LCD monitor of the mobile phone should be turned off.
