Abstract
A video signal, replay by a video player, is subjected to image processing by a calculation control part of a video image searching device to calculate the image quality value and another feature value. An image whose image quality satisfies a predetermined condition and whose feature value matches a predetermined condition is detected as an image in which an event has occurred. Such images are printed on an output paper together with associated addition information. A main control part of a video image access device reads out the additional information on the output paper by a scanner and effects control via a video control part to search the image corresponding to that information by a video player.
