Abstract
Abstract A video source (101), such as a VCR, plays back a motion image which is input by an image input section (111). Partition of scenes and creation of images representing scenes are performed by a catalog creation section (120). Additionally, at this time, an image representing the movement of an object appearing in the scenes is created. A representative image and a motion description image are initially stored in a catalog storage section (130) and then displayed in catalog form by a display section (104) under control of a display control section (114). Since not only the representative image of scenes but also the movement of the object in those scenes are displayed, the contents of the scenes are easily grasped.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A representative image display method comprising: a scene partition process for partitioning into scenes a motion image comprising a sequence of multiple images, a representative image selection process for selecting a representative image to represent each partitioned scene, a change detection process for detecting changes occurring in an object within each partitioned scene, a change information hold process for associating and holding information related to the detected changes for each scene with the representative image of the scene, and a display process for combining and displaying, for at least one scene, the representative image of the scene with its associated change information.
Claim 2
Dependent Claim
136 words
A representative image display apparatus comprising: an image input section (111) for inputting and storing a motion image comprising a sequence of multiple images, a scene partition section (121) for analyzing the input motion image, detecting transition points in the scenes, and partitioning the motion image into scenes, a representative image selection section (122) for selecting a proper image from the motion image comprising multiple scenes and setting it as a representative image, a change information hold section (120, 130) for detecting changes occurring in an object in each scene and associating and holding the information related to the change for each scene with the representative image of the scene, and a display control section (114) for combining and displaying, for at least one scene, the representative image of the scene with its associated change information.
Claim 3
Dependent Claim
70 words
The representative image display apparatus according to claim 2, wherein changes occurring in the object are caused by movement of the object, and the change information hold section (120, 130) detects the movement of the object based on a difference among a plurality of images, and the display control section (114) displays text which indicates the movement of the object included in the images when it displays the representative image.
Claim 4
Dependent Claim
83 words
The representative image display apparatus according to claim 2, wherein changes occurring in the object are caused by movement of the object, and the change information hold section (120, 130) detects the movement of the object based on a difference among a plurality of images, and further includes a motion description image creation section (123) which creates an image visually showing the movement of the object, and the display control section (114) combines and displays the representative image and the motion description image.
Claim 5
Dependent Claim
56 words
The representative image display apparatus according to claim 4, wherein said motion description image creation section (123) fetches, at a preset time interval, the image stored in the image input section and creates its outline image, and superimposes the outline image onto a previously created motion description image to repeatedly create a new motion description image.
Claim 6
Dependent Claim
40 words
The representative image display apparatus according to claim 5, wherein said motion description image creation section (123) creates new motion description images while changing colors of the outlines based on the elapsed time from the start time of the scene.
Claim 7
Dependent Claim
48 words
The representative image display apparatus according to claims 4 through 6, wherein said display control section (114) highlights the position of an object in a motion description image at a specified time, when an arbitrary time is specified between the start time and end time of a scene.
Claim 8
Dependent Claim
49 words
The representative image display apparatus according to claim 7, wherein said display control section (114) scans for pixels having a color corresponding to the given time, and highlights the location of the object in a motion description image by changing the color of all the pixels found by scanning.
Claim 9
Dependent Claim
73 words
The representative image display apparatus according to claim 2, wherein changes occurring in the object are changes in color of the object, and the change information hold section (120, 130) detects a change in color of the object based on differences among a plurality of images and the display control section displays text which indicates the change in color of the object when said display control section (114) the representative image is displayed.
Claim 10
Dependent Claim
116 words
A motion image search apparatus for performing searches for a motion image, comprising: the representative image display apparatus according to claims 2 through 9, a video source (101) for playing back and supplying a motion image to said representative image display apparatus, a video source control section (112) for controlling the playback of the motion image from the video source, and a command input section (103) for inputting commands for search processing, wherein the video source control section (112) performs, when one scene from displayed scenes and a playback start time for the scene are specified by a command, playback of the motion image from the playback start time of the scene based on the command.
