Method and apparatus for image selection in image transmission system
First Claim
1. A method for selecting a desired video image of a viewer from a plurality of video images provided by an image source, in an image transmission system for transmitting video images from the image source to an image display device, the method comprising the steps of:
- sequentially obtaining feature information for identifying targets shown in each of said plurality of video images;
entering a desired feature information for identifying a desired target of the viewer; and
sequentially selecting the desired video image which contains the desired target of the viewer from said plurality of video images according to the feature information sequentially obtained at the sequentially obtaining step and the desired feature information entered at the entering step.

Abstract
A scheme for image selection in an image transmission system for transmitting images from an image source to an image display device, capable of eliminating a need for the viewer to select the desired image by actually watching individual images and easily selecting the desired image in which a specific desired target of the viewer is shown. Feature information for identifying targets shown in each image is obtained, while a desired feature information for identifying a desired target specified by the viewer is entered. Then, the desired image which contains the desired target specified by the viewer is selected according to the obtained feature information and the entered desired feature information. The feature information may be obtained by recognizing targets shown in each image provided by the image source, or may be generated in advance in correspondence to images provided by the image source.
