Abstract
The moving images under reproduction are displayed in a main screen and a plurality of thumbnail images that serve as indexes by which to search for a desired scene are displayed. Moreover, the thus displayed thumbnail images are updated at a predetermined timing according as the moving images progress.
Claims23
An image processing method, including:
- controlling to cause to display, at the time when moving images are displayed, a plurality of reduced images in a manner such that a temporal relation of the reduced images to progression of the moving images is recognizable;
- and
- controlling to cause to update the displayed reduced images according to the progression of the moving images.
An image processing apparatus, including:
- a display controller which displays, at the time of displaying moving images, a plurality of reduced images on a same screen displaying the moving images, in a manner such that a temporal relation of the reduced images to progression of the moving images is recognizable;
- and
- a reduced-image updating unit which updates the displayed reduced images according to the progression of the moving images.
Apparatus for recording and reproducing images, including:
- an image extracting unit which acquires moving image signals and extracts unit images that constitute the moving images;
- an image selector which selects an original image of an index image used in the search of a desired scene among the moving images, from the unit images extracted by said image extracting unit;
- a first data recorder which stores the moving images;
- an index image generator which generates the index image by reducing the size of the selected original image;
- a second data recorder which records and stores the index image in a manner such that the index image is associated with the original image;
- an index image specifying unit which selects a predetermined index image from said second data recorder, according to progression of the moving images;
- and
- an index updating unit which updates the index image according to progression of the moving images.

Apparatus for recording and reproducing images, including:
- a first decoder which acquires coded data and decodes unit images that constitute moving images;
- an image selector which selects an original image of an index image used in the search of a desired scene among the moving images, from the unit images decoded by said first decoder;
- a first data recorder which stores the coded data;
- an index image generator which generates the index image by reducing the size of the selected original image;
- an encoder which intra-image codes the index image and compresses a data amount of the index image;
- a second data recorder which stores the coded index image in a manner such that the index image is associated with the original image;
- a second decoder which selects and decodes a predetermined index image along with progression of the moving images;
- and
- an index updating unit which controls to cause to update the decoded index image along with progression of the moving images.
6 more elements
Apparatus for recording and reproducing images, including:
- a first MPEG decoder which acquires coded data that are moving image signals coded in compliance with an MPEG standard, and which decodes unit images that constitute moving images;
- an image selector which selects an original image of an index image used in the search of a desired scene among the moving images, from the unit images decoded by said first MPEG decoder;
- a first data recorder which stores the coded data;
- an index image generator which generates an index image by reducing the size of the selected unit images;
- an MPEG encoder which intra-image codes the index image;
- a second data recorder which stores the coded index image in a manner such that the coded index image is associated with an original image thereof;
- a second MPEG decoder which decodes a predetermined index image;
- an index area generator which generates an index area constituted by using the decoded index image so that a relationship in terms of time with progression of the moving images can be recognized;
- and
- a display controller which controls to cause to display the index area.
7 more elements
A television receiver, including:
- a tuner unit which receives television broadcast signal waves that has been subject to a predetermined modulation, and which demodulates the signal waves into transport streams in which moving image signals coded in compliance with an MPEG standard are multiplexed;
- a TS separator which separates coded data of the moving image signals from the transport streams;
- a first MPEG decoder which acquires the coded data and decodes unit images that constitute moving images;
- a first data recorder which stores the coded moving image signals;
- an image selector which selects an original image of an index image used in the search of a desired scene among the moving images, from the unit images decoded by said first MPEG decoder;
- an index image generator which generates an index image by reducing the size of the selected unit images;
- an MPEG encoder which intra-image codes the index image;
- a second data recorder which stores the coded index image in a manner such that the coded index image is associated with an original image thereof;
- a second MPEG decoder which decodes a predetermined index image;
- an index area generator which generates an index area constituted by using the decoded index image so that a relationship in terms of time with progression of the moving images can be recognized;
- a display controller which controls to cause to display the index area;
- and
- a scene determining unit which, in the event that any of the index images constituting the index area is selected by a user, resumes progression of the moving images from an image associated with the selected index image.
