  FIG. 1 is a schematic block diagram showing an image reproducing apparatus according to the present invention.

  In FIG. 1, 101 is a drawing unit that draws a rectangle or the like on image data in the image memory 102, 102 is an image memory that stores image data, 103 is an image processing unit that performs image processing such as enlargement / reduction, and 104 is a user. 10 is a display unit such as an LCD for displaying image data stored in the image memory 102, 106 is a CPU for controlling the entire image reproducing apparatus, and 107 is data recorded on the recording medium 108. This is a playback unit that reads a file and restores a playback image. Reference numeral 108 denotes a removable recording medium such as a disk or a memory card. 101 to 107 constitute an image reproduction apparatus. During normal image reproduction, the reproduction unit 106 reads data from the recording medium 108 set in the image reproduction apparatus, restores the reproduction image, and an image processing unit. The image processing for display is performed by 103 and stored in the image memory 102, and the display unit 105 displays the reproduction data stored in the image memory 102.

  FIG. 2 is an image diagram of index display in the image reproducing apparatus according to the present invention. In FIG. 2, image 1 is a normal still image file, image 2 is a continuous shooting object, image 3 is a moving image file, image 4 is a continuous shooting object, image 5 is a moving image file, and image 6 is a normal still image file.

  First, when the normal still image file 6 is displayed as an index, a reduced image or thumbnail image of the image is displayed after image processing such as reduction.

  Next, an object associated with a plurality of still image files, such as continuous shooting, displays one reduced image or thumbnail image of a representative image in a plurality of images, and the drawing unit 101 according to the number of related files. Draws and displays a rectangle. The index display when the first image in the object is the representative image is image 2, and the index display when the third image from the top in the object is the representative image is image 4. The rectangle drawn in the upper right of the display image (reduced image of the representative image) indicates the number of files in the same object behind on the time axis, and the rectangle drawn in the lower left is in the same object preceding in the time axis Indicates the number of files. The drawing color of the rectangle differs before and after the representative image.

  Next, when displaying a moving image file as an index, the drawing unit 101 draws a rectangle on the upper right of one image or thumbnail image in the moving image. A rectangular area to be drawn is determined according to the recording time of the moving image file. Further, when the displayed image is one image in the moving image, the image draws the position in the time axis direction in the moving image file. Image 3 displays one image of a moving image file. In addition, the image 5 displays a thumbnail image of a moving image file.

  FIG. 3 is an image 4 in FIG. 2 and represents a continuous shooting object. The total number of images in the continuous shooting object is 6, and the displayed image is the third image from the top, which means that there are two images before this image and three images behind it. ing.

  FIG. 4 is an image 3 in FIG. 2 and represents a moving image file. If the recording time of the moving image file is S seconds, the length on the time axis representing the recording time S is L, and the length from the top of the displayed image on the time axis is m, the displayed image is the top To S × m / L seconds.

  FIG. 5 is an operation flowchart of the CPU 106 during index reproduction in the image reproduction apparatus according to the present invention.

  At the time of index reproduction, six images are displayed and set as a display image counter n.

  First, 0 is substituted into the display image counter n (S501). It is determined whether the display image counter n satisfies n <6 (S502). If NO, the process ends. If YES, object information including the object type, recording time, number of images, etc. is obtained from the desired image object recorded on the recording medium 108 (S503). Whether the object is a moving image object is determined from the object information acquired in S503 (S504). If YES, the recording time is acquired from the object information acquired in S503 (S505). Next, the position on the time axis of the moving image object representative image is acquired (S506).

  If NO in S504, it is determined from the object information acquired in S503 whether the object is a continuous shooting object (S511). If YES, the number of continuous shots is acquired from the object information acquired in S503 (S512). Next, representative image position information in which it is designated which image of the continuous shooting object is the representative image is acquired (S513).

  After executing the processing of S506 and S513, the drawing unit 101 generates a rectangular icon from the recording time and representative image position for a moving image object, and the total number and representative image position for continuous shooting objects (S507). Next, the representative image and the rectangular icon generated in S507 are synthesized (S508).

  If NO in S511, the thumbnail image is reproduced (S514).

  The composite image of S508 and the thumbnail image of S514 are displayed on the display unit 105 (S509). Next, n + 1 is substituted into the display image counter n, and the process proceeds to S502 (S510).
