Description

  The present invention attaches a removable portable memory in which both original image data representing an original image and thumbnail image data representing a thumbnail image of the original image are recorded, and the original recorded in the portable memory. The present invention relates to an image reproducing apparatus that displays an original image and a thumbnail image based on image data and thumbnail image data on a display screen.

  Conventionally, many digital cameras having a display screen have a function of an image reproducing device. As described above, when the digital camera has the function of an image playback device, if a removable portable memory in which a large number of image files are recorded is loaded in the digital camera, the image is recorded in the mounted portable memory. In addition, a captured image based on any captured image data in a large number of image files can be reproduced and displayed on a display screen of a display unit included in the digital camera.

  When replaying and displaying such a photographed image, the photographed image based on the image data obtained by the most recent photographing is first displayed on the display screen, and further, depending on the operation of the operator. In many cases, the pages are switched so as to go back to the past, and the already taken images are displayed one after another. By doing so, it is possible to easily search for an image that the user wants to see by switching the images one after another by performing an operation.

  However, when such an image search is performed, if an image based on the image data of each of the many image files recorded in the memory is reproduced and displayed on the screen one by one. , It may take longer than necessary to find the image you want to see.

  Therefore, in order to make it possible to search within a short time, in the case of shooting using the auto bracket function or continuous shooting function, only the first shot image is displayed. (For example, refer to Patent Document 1). Also, when an image is played back and displayed on the display screen, a thumbnail image representing another shot image is displayed below that image, and one shot image is played back and displayed according to the operation. In some cases, an image search can be performed during the process (see, for example, Patent Document 2).

  However, when finding out an image that one wants to see from an enormous number of image data, it takes too much time to search for an image even if the techniques of Patent Document 1 and Patent Document 2 are used.

  Therefore, there is a technique in which an index image composed of a plurality of thumbnail images (reduced images of the original image) is displayed on the display screen to further reduce the time required for the search (for example, Patent Document 3 and Patent Document). 4).

  FIG. 1 is a diagram showing the index image and a cursor displayed over the index image.

  The example shown in FIG. 1 shows an example in which nine thumbnail images are displayed on nine multi-screens, and a frame-like cursor is displayed so as to surround one of the nine screens. An example is shown.

  In the example shown in FIG. 1, for example, the cursor on the display screen is moved so as to raster-scan the index image for one page displayed on the display screen in accordance with the operation of the right key of the cross key, and the thumbnail at the end. After moving to the image, the index image of the next page is updated and the index image of the next page is displayed on the display screen. Further, after the index image is updated, if the operation of the operator is still continued, the cursor is moved so as to perform raster scanning on the index image of the next page.

  When it is desired to search for another image in the portable memory in this way, for example, while the right key of the cross key continues to be operated, the raster scanning movement of the cursor is repeated and the page is switched. As a result, the index images are updated and displayed one after another. In this way, for example, if you look at nine thumbnail images and think that it is not the image you want to see, you can quickly search for the image you want to find by continuing to operate the cross key. .

  When an index image composed of a plurality of thumbnail images is displayed in this way, a plurality of thumbnail images are displayed on one screen at a time, so the number of images to be searched on the screen for one page has increased. Search time is reduced. Further, in Patent Document 3, in order to further reduce the time required for the search, a region where a single thumbnail image is displayed is divided into a plurality of related thumbnail images representing, for example, continuously shot images. Since a plurality of images are displayed at a time, the time required for searching is further reduced. Furthermore, in Patent Document 4, when image files are grouped by shooting date and one thumbnail image in the index image is specified by operation, a plurality of images having the same shooting date and time as the specified thumbnail image are specified. Since the thumbnail image of the image file is displayed as an index image, the time required for the search is further reduced.

However, when performing an image search, not only one portable memory but also a plurality of portable memories may be included. As a result, the number of image data becomes enormous, and even if the cursor is moved so as to perform raster scanning according to the operation of the operation element, the related image is used for the purpose of shortening the search time as described above. Even if a device is devised to group them, the time to continue operating the search operator in proportion to the number of image data inevitably increases. In this way, there are some users who feel annoyed if they have to operate the search operator for a long time.
Japanese Patent Laid-Open No. 2003-101910 JP 2001-111408 A JP 2002-112079 A JP 2001-230992 A

  In view of the above circumstances, the present invention provides an image playback device having an image search function that allows a user to search for an image he / she wants to find in a short time with a simple operation without causing the user to feel troublesome. The purpose is to provide.

An image reproducing apparatus of the present invention that achieves the above object is provided with a removable portable memory in which both original image data representing an original image and thumbnail image data representing a thumbnail image of the original image are recorded. In an image reproducing apparatus for displaying an original image and a thumbnail image based on original image data and thumbnail image data recorded in the portable memory on a display screen,
An index image for one page in which a plurality of thumbnail images are arranged is displayed on the display screen, and when an index image for one page is displayed, of the plurality of thumbnail images constituting the index image A display control unit that displays the cursor on the position of one of the thumbnail images,
An operator for instructing movement of the cursor displayed on the display screen,
When the display control unit moves the index image for one page displayed on the display screen as a mode for moving the cursor on the display screen, and moves to the thumbnail image at the end, the display is performed. The normal mode in which the index image of the next page is displayed on the screen and moved so as to perform raster scanning is connected to the upper left and lower right of the index image for one page displayed on the display screen. It has a fast-forward mode that moves the direction and moves to the thumbnail image at the end, displays the index image of the next page, and moves on the index image in the above direction, and switches the mode according to the operation state of the operator And controlling the display on the display screen.

  According to the image reproducing apparatus of the present invention, when an image search is performed in the fast forward mode, the cursor moves in a direction connecting the upper left and lower right of the index image for one page. Since the cursor was moved horizontally by one frame so as to perform raster scanning as it is, it took a considerable time to move the cursor by one page. However, in the image reproducing apparatus of the present invention, Since the fast-forward mode is provided and the cursor is moved diagonally, the distance to move the cursor is shorter than when the cursor is moved so as to perform raster scanning, and if the cursor speed is the same, The cursor movement time is shortened. At this time, if the movement speed of the cursor becomes too fast, the cursor may move too fast and only the page change may be visible to the user, so the index image displayed on one screen By moving the cursor fast enough to read and understand the contents diagonally, the cursor movement time in the index image of one page is made shorter than before, and the time interval for switching pages is set. It is shortened.

  Then, during the period when you continue to operate the controls, you can search for a larger number of thumbnail images than before, and when searching for the same number of thumbnail images, The image you want to find will be found in a shorter time than the time required for. When an image that the user wants to find is found in such a short time, the time to continue operating the operation element is shortened, so that the user feels that the operation is troublesome.

  In this way, an image playback device having an image search function that allows a user to search for an image he / she wants to find in a short time with a simple operation without causing the user to feel troublesome is realized.

  Although the user may be allowed to select the normal mode and the fast-forward mode, the display control unit is configured so that the display control unit performs display on the display screen in the normal mode at the start of scanning of the operator. In addition to the control, when the operating element has been operated for a predetermined time or longer, it may be switched to the fast-forward mode for control.

  Then, when the operation element has been operated for a predetermined time or longer, the display control unit interprets that the image search is being performed, and the normal mode is automatically switched to the fast-forward mode. As described above, when the normal mode is automatically switched to the fast-forward mode according to the operation state of the operation element, the user does not have to bother to select the fast-forward mode in a short time. You can search for the image you want to find.

   As described above, an image playback device having an image search function that allows a user to search for an image he / she wants to find in a short time with a simple operation without causing the user to feel troublesome is realized. The

  FIG. 3 is a diagram showing an internal configuration of the digital camera 100.

  The operation of the digital camera 100 is comprehensively controlled by the CPU 111. The CPU 111 has a built-in ROM, and a program is stored in the built-in ROM. The overall operation of the digital camera 100 is controlled by the CPU 111 in accordance with the procedure of this program. The power switch 102, the shooting / playback mode switching lever 103, and the other switches 104 to 108 shown in FIG. 3D are all connected to the CPU 111. When any one of these switches is operated, the CPU 111 is operated. A signal is input.

  First, when the power switch 102 is turned on, the CPU 111 detects that the power switch 102 is turned on, and the lens barrier 1011 shown in FIG. 2 (e) is opened. As shown in FIG. 101 is paid out. At this time, the CPU 111 detects that the output of the barrier sensor 1011a has changed before the taking lens 101 is extended, and then the taking lens 101 is extended. When the photographing lens 101 is thus extended, the photographing process or the reproduction process is started by the CPU 111. The CPU 111 detects the switching position of the shooting / playback mode switching lever 103 when the power is turned on. If the detected switching position is the shooting mode 103a, the CPU 111 starts the shooting process and instructs the image playback processing circuit. The through image is displayed on the LCD panel 109a, and if the switching position is the reproduction mode 103b, the image data recorded on the recording medium 140 is read out to the media control circuit 115 and further the image reproduction processing circuit 117 via the bus. Is supplied with the image data. The image reproduction processing circuit 117 performs processing for converting the image data into display image data, and further supplies the display image data to the LCD drive circuit 109. The LCD drive circuit 109 causes the image based on the image data to be displayed. Is displayed.

  Here, the operation of the photographing process will be briefly described with reference to FIG.

  The CPU 111 detects that the mode switching lever 103 has been switched to the shooting mode 103a as shown in FIG. 3 and starts the shooting process. Image data representing the subject imaged on the CCD 110 is displayed at predetermined intervals. To the CDSAMP 111. The image data output at every predetermined interval is processed in the signal processing stage after the A / D converter 112 to obtain a through image, and the through image is displayed on the LCD panel 109a. Then, the subject within the range captured by the photographic lens 101 is displayed on the LCD panel 109a as if it were a moving image.

  Since the user arbitrarily performs framing and shooting based on the through image displayed on the LCD panel 109a, the subject in the direction toward the digital camera 100 is immediately displayed as a through image. The focus detection position is always detected by the AF detection circuit 130, and the focus lens 101a in the photographing lens 101 is moved to the focus position by the focus adjustment mechanism. The focus adjustment mechanism includes a focus lens 101a, a motor 101c that drives the focus lens 101a based on the detection result of the in-focus position of the AF detection circuit 130, and a lead screw that moves the focus lens 101a by the motor 101c (see FIG. And a sensor 101b for detecting the position of the focus lens 101a moved by the rotation of the lead screw.

  In addition to the focus adjustment by this focus adjustment mechanism, the AE & AWB detection unit 131 detects the field luminance and switches and sets a small aperture or an open aperture (not shown) for white balance adjustment. A clear through image is displayed on the LCD panel 109a by adjusting the gains of the color signals R, G, and B. The user performs framing while viewing the through image, and performs a release operation at a photo opportunity.

  When the release button 107 is pressed and a release operation is performed, the CPU 111 supplies a timing signal to the CCD 110 from a timing generator (not shown) in order to form an image at the time of the release operation on the CCD 110. This timing signal informs the CCD 110 of the start and end of exposure and corresponds to a so-called shutter speed. At the end of exposure, the CPU 111 outputs image data (consisting of the three primary colors R, G, and B of RGB light) from the CCD 110, and the output image data is supplied to the subsequent CDSAMP 111. In the CDSAMP 111, the noise of the image data output from the CCD 110 is reduced, and the image data with the reduced noise is supplied to the A / D converter 112. The image data composed of RGB converted into a digital signal by the A / D conversion unit 112 is supplied to the image signal processing circuit 113, and the image signal processing circuit 113 converts the RGB signal into the YC signal. Further, the YC signal is supplied to the compression / decompression processing circuit 114 and compressed, and the compressed image data is recorded as an image file on the recording medium 140 via the media control circuit 115.

  The digital camera 100 is provided with a shooting mode dial 106 for specifying a shooting mode. Among the shooting modes that can be specified with the mode dial 106, there is a moving image shooting mode. When the moving image shooting mode is designated by the shooting mode dial 106, audio data is recorded along with the moving image in addition to the moving image data based on the moving image. This audio data is audio recorded via the microphone 1002 when a moving image is being shot, and the audio recorded by the microphone 1002 is supplied to the audio processing circuit 116 as audio data. The sound processing circuit 116 converts the sound data suitable for the speaker 1003.

  If the CPU 111 determines that the audio data is during moving image shooting, the audio data and the moving image data are associated with each other and recorded on the recording medium 140 as a moving image data file.

  The operation of the image playback device provided in the digital camera having such a photographing function will be described.

  The operation of the image playback device is controlled centrally by the CPU, as in the digital camera. When the CPU 111 detects that the shooting / playback mode switching lever 103 has been switched to the playback 103b side, the CPU 111 causes the media control circuit 115 to read out the image data recorded in the recording medium 140, and the compression / decompression processing circuit 114. Then, the image reproduction processing circuit 117 is supplied with the image data that has undergone the decompression process. In this image reproduction processing circuit 114, the decompressed image data is subjected to processing suitable for the LCD monitor, and then the processed image data is output to the LCD drive circuit 109. The LCD drive circuit 109 receives the image data and drives the LCD panel 109a to reproduce and display an image based on the image data on the LCD panel 109a. In the digital camera of the present embodiment, when playing back and displaying, a selection menu is used to select whether to play back and display an image based on the image data over the entire screen or to display and play back a thumbnail image so that image search can be easily performed. It is made to be able to. If the photographer has selected the above-described “image search”, an index image as shown in FIG. 1 is displayed on the LCD panel 109a.

  The CPU 111 corresponding to the display control unit of the image playback apparatus provided in the digital camera 1 of the present embodiment performs raster scanning of the index image for one page displayed on the LCD panel 109a with a frame-like cursor, as in the past. When the image is moved to the thumbnail image at the edge, the index image of the next page is displayed on the LCD panel 109a, and the index image is moved to perform raster scanning, and a frame-like cursor is displayed on the display screen. A fast-forward mode in which the direction connecting the upper left and lower right of the index image for one page is moved to the thumbnail image at the end, the index image of the next page is displayed, and the index image is moved in the above direction on the index image. Have. The CPU 111 which is the display control unit of the image reproducing apparatus of this example displays the cursor in the normal mode at the start of scanning of the right key 104c of the cross key 104 which is an operator, and the cross key 104 is operated for a predetermined time or more. If the operation is continued, the cursor is automatically displayed by switching to the fast-forward mode.

  In this embodiment, switching is performed automatically. For example, two modes are displayed as selection items on the LCD panel, and one of them is selected by operating the cross key to fast forward to the normal mode. The mode may be switched.

  FIG. 4 is a diagram for explaining a display example of the index image and the cursor in the normal mode and the fast-forward mode controlled by the CPU of the present embodiment.

  The index images shown in FIGS. 4A and 4B are the same index image, but the movement of the frame-like cursor differs between the left and right index images. In FIG. 4A, it is indicated by an arrow that the cursor moves so as to perform raster scanning in the normal mode, and FIG. 4B is displayed on the display screen in the fast-forward mode. The movement of the index image for one page in the direction connecting the upper left and the lower right is indicated by an arrow.

  As described above, when “image search” in one item in the selection menu is selected, an index image and a cursor shown in FIG. 4 are displayed.

  In the image reproducing apparatus of the present embodiment, the CPU 111 instructs the media control circuit 115 to read and read a large number of thumbnail image data in the header portion of the image file recorded on the recording medium 140 and read them out. The image is temporarily stored in the frame memory in the media control circuit 115. When stored in the frame memory, nine thumbnail images among the many thumbnail images are supplied to the image reproduction processing circuit so that the nine thumbnail images are displayed as a list of index images. At this time, the CPU 111 supplies a cursor display instruction to the LCD drive circuit 109 via the image reproduction processing circuit 117 to cause the LCD drive circuit 109 to display the cursor. In this example, the CPU 111 calculates the frame advance number in accordance with the operation time of the cross key, and further calculates the display position of the thumbnail image in accordance with the frame advance number from the current position of the cursor. The reproduction processing circuit and the LCD drive circuit 109 are notified to cause the LCD drive circuit to drive the LCD panel 109a and display a cursor on the LCD panel 109a. Further, the CPU 111 notifies the image reproduction processing circuit 117 and the LCD drive circuit that raster scanning is performed, and displays a cursor so that the LCD drive circuit performs raster scanning. As a result, as shown in FIG. 4, a frame-shaped cursor is displayed over the index image, and the cursor moves in the raster direction indicated by the arrow. The CPU 111, the reproduction processing circuit 117, and the LCD drive circuit 109 correspond to the display control unit referred to in the present invention.

  In the conventional example of FIG. 1, the cursor is merely moved so as to perform raster scanning in this way. However, in the image reproducing apparatus of this embodiment, the cursor is controlled in the raster scanning direction as shown in FIG. As shown in FIG. 4B, the cursor can be moved obliquely. Here, two modes are described in the program, and when the cross key is continuously operated over a predetermined time, switching from the normal mode to the fast-forward mode is automatically performed, for example, diagonally The position of the three thumbnail images at the position is notified as the movement position, and the cursor is moved further obliquely, so that the image reproduction processing circuit and the LCD drive circuit are notified, and the cursor is moved obliquely to the LCD drive circuit. The cursor is displayed on.

  By doing so, it is interpreted that the image search is performed according to the operation time of the cross key without having to bother to select the image search with a switch or a menu, and the mode is automatically switched to the fast forward mode. Become.

  FIG. 5 is a flowchart showing a procedure of processing related to image search performed by the CPU 111.

  If 'image search' is selected on the menu screen, the process of this flow is started.

  In step S501, an index image and a cursor for one page are instructed to the image reproduction processing circuit 117, and the LCD panel 109a is driven by the LCD drive circuit 109 to be displayed. Proceeding to the next Step S502, it is determined whether or not the cross key 104 has been operated. If it is determined to be present, the process proceeds to the next step S503, and it is determined whether or not the operation continuation time of the cross key 104 is longer than a predetermined time T. If it is determined in step S503 that the predetermined time T has not been continued, the process proceeds to No, the normal mode is set, and the cursor is moved in the raster scanning direction by the number of frames corresponding to the cursor operation time. Returning to step S502, it is determined whether or not the cross key is operated. If the cross key 104 is not operated here, the cursor is stopped.

  If it is determined in step S503 that the operation has been continued for a predetermined time T or longer, the process proceeds to the Yes side, the fast-forward mode is set in step S506, and the diagonal movement of the cursor is started in step S507. When the diagonal movement of the cursor is started in this step S506, the diagonal movement is continued until the cursor moves to the end. Proceeding to the next step S508, it is determined whether or not the operation of the cross key is continued. If it is determined that the operation is not continued, the process proceeds to the No side and the cursor is stopped in step S511. If the operation of the cursor is continued, the process proceeds to step S509 and it is determined whether or not the position of the cursor has moved to the diagonally right end. If it is determined in this step S509 that it has not moved to the end, the process proceeds to the No side, and the processing from step S508 to step S509 is repeated. If it is determined in this step S509 that it has moved all the way, the process proceeds to the Yes side, and the process proceeds to the next step S510 where the page is switched to update and display the index image. Returning to step S508, it is determined whether or not the operation of the cross key is continued. If it is determined that the operation is continued, the process proceeds to Yes, and the processing from step S508 to step S510 is repeated, and if it is determined that the operation is not continued in step S508. The process proceeds to No, and the cursor is stopped in step S511 to end the processing of this flow.

  In this way, for example, when the right key 104c of the cross key 104 is operated for a predetermined time or more, it is interpreted that the image search is being performed by the CPU 111 as the display control unit, and the normal mode is changed. It is automatically switched to the fast forward mode. As described above, if the normal mode is automatically switched to the fast-forward mode according to the operation state of the operation element, the image search can be performed by a simple operation without making the user aware of the fast-forward mode. An image reproducing device that can be performed is achieved. In addition, until now, the index image is displayed and the cursor is moved so as to perform raster scanning by the operation key. However, in the present invention, the operation time tends to be slightly extended. By moving to, the user feels that the page is being switched more efficiently, making it difficult for the user to feel troublesome.

  As described above, an image reproduction apparatus having an operation function that allows a user to search for an image he / she wants to see in a short time without causing the user to feel bothered is realized.

  In the present embodiment, a digital camera provided with an image playback device is taken as an example, but a dedicated image playback device may be used.

It is a figure which shows an index image and the cursor displayed on the index image so that it may overlap. It is a figure which shows the external appearance of the digital camera which is one Embodiment of this invention. It is a figure which shows the internal structure of the digital camera 100 of FIG. It is a figure explaining the example of a display of the index image and cursor in the normal mode and fast-forward mode which CPU of this embodiment controls. It is a flowchart which shows the procedure of the process which concerns on the image search which CPU111 performs.
