Abstract
Abstract A method and a system for video recording, in which scenes desired by a user can be recorded, are provided. Even at a case that the user sets the starting time and the ending time of a program beforehand and its broadcasting time is changed, and at a case that the user does not know the contents of the program in detail, the program or the scenes desired by the user can be recorded by the method and the system. The method for video recording provides the steps of; detecting an inputted face image from a video signal composed of plural frames, identifying the inputted face image with an inquiring face image designated by a user, and recording video signals including frames before and after a frame in which the inquiring face image appears for designated minutes when identification between the inputted face image and the inquiring face image was successful, or not recording video signals including frames before and after a frame in which the inquiring face image appears for designated minutes when identification between the inputted face image and the inquiring face image was successful.
