Description

  The present invention relates to an image processing apparatus that uses two display devices having different display capabilities.

  2. Description of the Related Art In recent years, video recording / reproducing apparatuses that record and reproduce images using a disk medium such as a magnetic disk and an optical disk and a randomly accessible recording medium such as a flash memory have appeared. Such a random access recording medium has come to be used for a recording medium of a video camera.

  In general, a video camera includes a display device (attached monitor device) that reproduces and displays a recorded image, and also includes a video output terminal so that the external monitor device can display the reproduced image. However, as shown in FIG. 10, in the conventional video camera, the same image signal is applied to the attached monitor device and the external monitor device connected to the video output terminal with a cable, and the same image is displayed.

  Not only a video camera but also a device that handles a large number of recorded images, such as a video recording / playback device, thumbnails of a plurality of recorded images are often displayed in a list on one screen. With this function, the user can easily select an image to be reproduced from a plurality of recorded images. Note that the thumbnail is a still image in which the data size or the number of pixels is reduced by thinning processing, for example. In the case of a moving image, a thumbnail is generated from a typical screen image in the moving image, for example, a screen image after a predetermined time from the head position.

  The video camera is small enough to fit in the palm of the hand, and the display size of the attached monitor device is about 2 to 5 inches. On the other hand, as the external monitor device, a general television receiver can be used, so that an external monitor device of 15 inches or more, sometimes 37 inches or more is also used.

  In the thumbnail list display, for example, as shown in FIG. 10, at most six thumbnail images are displayed on one screen so that the user can easily identify the contents of each thumbnail on the screen of the attached monitor device. However, when a large-screen monitor device that can be used as an external monitor device is used, the individual thumbnails are too large, and therefore the number of thumbnails displayed simultaneously is too small. Even if more thumbnails are displayed simultaneously, the user can identify the contents of each thumbnail.

Patent Document 1 describes a display processing technique in which thumbnail display sizes can be changed using a menu, and thumbnails of a selected display size are displayed as a list corresponding to the display size when connected to an external television apparatus. Has been.

  However, when an external monitor device is connected and an image is reproduced and displayed, the user operating the main body may not always be able to completely see the screen of the external monitor device. In such a situation, the user needs to perform an operation while looking at the screen of the attached monitor device of the main body.

  Even if an external monitor device is connected, the image signal output from the main body is not always displayed on the external monitor device, and even if it is displayed, the user views the screen of the external monitor device. It may not be.

  From this point of view, if the display size or the number of displayed thumbnails is changed when an external monitor device is connected, the operation while viewing the attached monitor device becomes impossible or extremely difficult.

In order to solve the above problems, an image processing apparatus according to the present invention includes an image recording apparatus that records a plurality of image data, and a first display that displays a list of up to N display images indicating the plurality of image data. An image processing unit for generating a list display image, a second list display image for displaying a list of up to M images for display indicating the plurality of image data, and displaying the first list display image For selecting image data for each of the attached monitor device, the external output control device for outputting the second list display image to the external monitor device, and the first list display image and the second list display image To select one of the plurality of image data by superimposing the selection images and moving the selection image in the same direction in the first list display image and the second list display image and the part, the accessory monitor Device by displaying the first list display image, and the external monitor when the state of displaying the second list display image by the apparatus, the following operation of the operating section first list image And a control unit that individually controls updating of the first list display image and the second list display image by the image processing unit so that the same image data is selected in each of the second list display images. It is characterized by comprising .

  According to the present invention, it is possible to perform an operation of selecting an image to be recorded on the image recording apparatus while viewing either the attached monitor device or the external monitor device. Further, by utilizing the screen size of the external monitor device, more information can be displayed at the same time, and the user can select an image efficiently.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of an image processing apparatus according to a first embodiment of the present invention applied to a digital video camera for recording moving image data on a disk type recording medium.

  The video camera 10 includes a camera unit 12 and a codec (CODEC) 14 that encodes and decodes image data. The video camera 10 also includes a buffer memory 16 and a disk controller 18 that writes and reads data to and from the disk 20 for recording and reproducing captured images.

  An image processing unit 22, an image memory 24, an LCD control device 26, a liquid crystal display (LCD) 28, an image memory 29, an external output control device 30, and an external output terminal 32 are provided for image display, thumbnail list display, and menu display. It has. The external monitor device 60 can be connected to the external output terminal 32 by the connection cable 50.

  The CPU 34, RAM 36 and ROM 38 are connected to the internal bus 40. A camera unit 12, codec 14, disk control device 18, image processing unit 22, LCD control device 26, and external output control device 30 are also connected to the internal bus 40. The CPU 34 controls the camera unit 12, the codec 14, the disk control device 18, the image processing unit 22, the LCD control device 26, and the external output control device 30 via the bus 40. The operation unit 42 includes various operation levers and buttons operated by the user, and is used to input a user instruction or selection to the CPU 34.

  The moving image recording operation of this embodiment will be described. The camera unit 12 includes an image sensor that converts an optical image of a subject into an electrical image signal, and outputs a digital signal of a captured image to the codec 14. When the user instructs the CPU 34 to start image recording through the operation unit 42, the CPU 34 activates the camera unit 12 to start an imaging operation (operation to convert an optical image into an image signal), controls the codec 14, and controls the camera. The image data from the unit 12 is read and compressed and encoded. Thereby, the image data is converted into compressed data compressed by the MPEG method, so-called MPEG data. The MPEG data is buffered in the buffer memory 16 and supplied to the disk controller 18. The disk controller 18 records MPEG data from the buffer memory 16 on the disk 20. In this way, the moving image is compression-encoded and recorded on the disk 20. A unit of one moving image recorded in this way is called a clip. The buffer memory 16, the disk control device 18, and the disk 20 correspond to the image recording device in the claims.

  When reproducing any clip recorded on the disc 20, first, a list of clips recorded on the disc 20 is displayed as thumbnails. The thumbnail list display operation will be described. The thumbnail corresponds to a display image in the claims.

  The CPU 34 controls the disk control device 18 to sequentially read out the head images of a predetermined number of clips displayed as a list from the disk 20 and their associated information, for example, information on file names and shooting dates and times. Additional information includes data size or shooting parameters. The read compressed image data of the head image is transferred to the codec 14 via the buffer memory 16, and the attached information is transferred to the CPU 34. The codec 14 decodes (decompresses) the compressed image data of the head image. The image processing unit 22 resizes the decoded head image data, and generates a thumbnail having a size for displaying an attached monitor and a thumbnail having a size for displaying an external monitor. The former is called an attached monitor thumbnail, and the latter is called an external monitor thumbnail. The CPU 34 converts the attached information from the disk control device 18 from character code to image data and supplies it to the image processing unit 22.

  The image processing unit 22 stores the attached monitor thumbnail in the memory position corresponding to the display position on the image memory 24. Further, the image processing unit 22 stores the external monitor thumbnail together with the image data indicating the attached information in a memory position corresponding to the display position on the image memory 29.

  Of course, two types of thumbnails are created from one head image read from the disk 20, but the head image may be read from the disk 20 twice. At this time, the image processing unit 22 generates one of the attached monitor thumbnail and the external monitor thumbnail from the first read first image, and generates the other from the second read first image.

  The LCD control device 26 repeatedly reads out the image data stored in the image memory 24 and supplies it to the LCD 28. As a result, one or more thumbnails stored in the image memory 24 are displayed in a list in units of a predetermined number on the screen of the LCD 28 which is an attached monitor device. The image stored in the image memory 24 and displayed on the LCD 28 corresponds to the first list display image in the claims.

  The external output control device 30 repeatedly reads out image data stored in the image memory 29, converts it into an image signal in a standard video format, and outputs the image signal to the external output terminal 32. On the screen of the external monitor device 60 connected to the external output terminal 32 via the cable 50, one or a plurality of thumbnails stored in the image memory 29 are displayed as a list together with their respective accessory information in units of a predetermined number. The image stored in the image memory 29 and displayed on the external monitor device 60 corresponds to the second list display image in the claims.

  FIG. 2 is a diagram illustrating an external configuration example of the operation unit 42. The operation unit 42 includes a cross lever 42a, a zoom lever 42b, a rewind button 42c, a fast forward button 42d, a play / pause button 42e, and a stop button 42f. When displaying a list of thumbnails, the selection target can be changed by tilting the cross lever 42a up, down, left, or right. When the playback / pause button 42e is pressed, playback of the clip for the selected thumbnail starts. When the stop button 42f is pressed during clip reproduction, or when a series of reproduction ends, the thumbnail list display is resumed.

  FIG. 3 shows an example of a thumbnail list display. It is assumed that clips C1 to C22 are recorded on the disk 20 and the clip C9 is selected by a user operation.

  On the LCD 28, thumbnails of the clips C7 to C12 are displayed side by side, three in the horizontal direction and two in the vertical direction. Number in the horizontal direction: X = 3, LCD display number: N = 6. On the other hand, on the external monitor device 60, thumbnails of the clips C1 to C15 are displayed from the left side of the screen, with three in the horizontal direction and five in the vertical direction. Number in the horizontal direction: X = 3, number of displays on the external monitor device: M = 15. In both screens, a selection frame such as a border indicating the selection state is additionally displayed on the thumbnail of the selected clip C9. On the right side of the screen of the external monitor device 60, a preview image frame 70 in which a clip for the selected thumbnail (here, clip C9) is automatically reproduced is displayed. Below the preview image frame 70, a seek bar 72 indicating the playback position of the clip in the preview image frame 70 and attached information 74 such as the name of the clip being reproduced as the preview image frame 70 and the shooting date and time are displayed. .

  As shown in FIG. 3, from the state in which the clip C9 is selected, when the user tilts the cross lever 42a once, the clip C6 positioned above the clip C9 on the screen as shown in FIG. It will be in the selected state.

  Since the newly selected clip C6 is out of the range of the clips C7 to C12 displayed on the LCD 28 before the operation, the CPU 34 newly reads the first image of the clips 1 to 6 from the disc 20 and displays its thumbnail. Is generated by the image processing unit 22. That is, when moving a clip, if the destination clip has already been displayed, the CPU 34 moves only the selection frame on the same screen. If the destination clip is not displayed, the CPU 34 displays the currently displayed thumbnail. Is updated with a thumbnail of another clip, that is, updated in units of screens. As a result, a list of thumbnails of the clips C1 to C6 is displayed on the LCD 28, and a selection frame is additionally displayed on the clip C6 on the screen of the LCD 28.

  On the other hand, on the screen of the external monitor 60, since the newly selected clip C6 is within the range of the clips C1 to C15 displayed before the operation, the thumbnails displayed in a list are not updated. Only the selection frame moves to clip C6.

  When the user tilts the cross lever 42a three times from the state where the clip C9 is selected as shown in FIG. 3, the selected clip moves to the clip C12, the clip C15, and the clip C18. The state shown in FIG. 5 is obtained. The CPU 34 performs the following control in accordance with the operation of the cross lever 42a.

  In the movement from the clip C9 to the clip C12, only the selection frame moves on the screen of the LCD 28 and the screen of the external monitor device 60. In the movement from the clip C12 to the clip C15, the thumbnail list display of the clips C13 to C18 is updated on a screen basis on the screen of the LCD 28, and the selection frame moves to the clip C13. In the external monitor device 60, only the selection frame moves. In the movement from the clip C15 to the clip C18, only the selection frame moves on the screen of the LCD 28. Since the clip C18 is not displayed on the screen of the external monitor device 60, the thumbnail list display of the clips C16 to C22 is updated for each screen, and the selection frame is additionally displayed on the thumbnail of the clip C18.

  In this example, when moving a clip, if the destination clip has already been displayed, only the selection frame is moved on the same screen, and if the destination clip is not displayed, the thumbnail is displayed on the screen. Update the thumbnail of another clip in units (ie, in units of N or M).

  In this embodiment, the number of thumbnails displayed in a list is the same in the attached monitor device (LCD 28) and the external monitor device 60, and the number of vertically arranged external monitor devices 60 is larger than that in the attached monitor device. Thus, although the number of thumbnails displayed on the attached monitor device (LCD 28) and the external monitor device 60 is different, the same clip selection state can be maintained by operating the cross lever 42a of the operation unit 42. That is, the operation while viewing the screen of the attached monitor device (LCD 28) and the operation while viewing the screen of the external monitor device 60 do not differ at all. According to the present embodiment, the poor operability of the conventional example can be solved.

  A second embodiment of the present invention will be described. In the second embodiment, the display screen update method for an operation of selecting a clip outside the range displayed on the external monitor device 60 is different from the first embodiment. In the second embodiment, when the destination clip is not displayed, the displayed clip is scrolled up or down so that the destination clip is included in the display range. That is, the thumbnail is updated in units of one line (that is, in units of X).

  For example, as in the first embodiment, it is assumed that clips C1 to C22 are recorded on the disc 20, and the clip C9 is selected by a user operation. At this time, as in the first embodiment, as shown in FIG. 3, a list of thumbnails is displayed on the screens of the LCD 28 and the external monitor device 60 as shown in FIG.

  As shown in FIG. 3, when the user tilts the cross lever 42a three times while the clip C9 is selected, the selected clip moves to the clip C12, the clip C15, and the clip C18. The state shown in FIG. 6 is obtained. That is, in the movement from the clip C9 to the clip C12 and the movement from the clip C12 to the clip C15, only the selection frame moves on the screen of the external monitor 60. When moving from the clip C15 to the clip C18, on the screen of the external monitor 60, the clip to be displayed is scrolled in units of one thumbnail in the vertical direction, that is, three thumbnails arranged side by side, and the clips C4 to C18 are displayed. The selection frame moves to clip C18.

  A third embodiment of the present invention will be described. A dial switch is used instead of the cross key 42a. As shown in FIG. 7, the operation unit 42 is provided with a dial switch 342a. In the thumbnail list display, the selected image can be moved in the forward direction or the reverse direction by rotating the dial switch 342a up and down. When the playback / pause button 42e is pressed, playback of the clip for the selected thumbnail starts. When the stop button 42f is pressed during clip reproduction, or when a series of reproduction ends, the thumbnail list display is resumed.

  FIG. 8 shows an example of a thumbnail list display. Also here, it is assumed that clips C1 to C22 are recorded on the disc 20, and the clip C9 is selected by the user's operation.

  On the LCD 28, thumbnails of the clips C7 to C12 are displayed side by side, three in the horizontal direction and two in the vertical direction. Number of horizontal directions: P = 3, number of LCD displays: N = 6. On the other hand, the thumbnails of the clips C1 to C20 are displayed on the external monitor device 60 side by side, with five in the horizontal direction and four in the vertical direction. Number in the horizontal direction: Q = 5, number of display on the external monitor device: M = 20. In both screens, a selection frame such as a border indicating the selection state is displayed on the thumbnail of the selected clip C9. Also, attached information such as the shooting time of the clip is displayed below each thumbnail displayed on the external monitor device 60.

  Assume that the user rotates the dial switch 342a downward by 12 steps from the state in which the clip C9 is selected as shown in FIG. In response to this rotation operation, under the control of the CPU 34, the selected clip moves from the clip C9 to the clip C21 in increments of one clip, resulting in the state shown in FIG.

  In the movement from the clip C12 to the clip C13 and the movement from the clip C18 to the clip C19, the newly selected clip is out of the range of the clip displayed on the LCD 28 before the operation. Accordingly, the thumbnails displayed on the LCD 28 are updated to different thumbnails in units of screens (that is, in units of N).

  Further, in the movement from the clip C20 to the clip C21, the newly selected clip is out of the range of the clip displayed on the external monitor device 60 before the operation. At this time, the thumbnails displayed on the external monitor device 60 are scrolled vertically in units of one line, that is, in Q units, and the screen of the external monitor device 60 has clips C6 to C22 as shown in FIG. A thumbnail is displayed.

  Regardless of the movement of any clip, both the LCD 28 and the external monitor device 60 move the selection frame according to the operation of the dial switch 342a.

  In this embodiment, the dial switch 342a selects between clips in the normal order or the reverse order. At that time, on the screen of the LCD 28 which is an attached monitor device, the thumbnail is updated in units of planes, and in the external monitor device 60, the thumbnail is updated in units of rows in the vertical direction. Thus, a desired clip can be selected by the same operation while looking at the LCD 28 or looking at the external monitor device 60.

  In any of the above-described embodiments, any element that can identify the selected state and the non-selected state, such as a selection symbol, a selected character, or a display color, can be used in addition to the selection frame as an element indicating the selection state of the clip.
