Patent ID: 7742686

Claim:
A signal processor for processing image signals including a plurality of image frames, comprising: a buffer memory for storing the image signal and outputting the stored signal as a main image signal; a point setting part for setting, in response to a given capture instruction, a position on a time axis of the main image signal corresponding to the capture instruction, as a registration point, and instructing generation of a registration image; a playback control part for causing said buffer memory to output the image frame from the registration point used as a starting point in response to a given playback instruction; a capture processing part, when instructed by said point setting part, for generating a registration image of a lower resolution than image frames of said main image signal based on at least one image frame of the main image signal outputted from said buffer memory and storing the registration image, said at least one image frame being placed at the registration point in a neighborhood of the registration point; a point recording part for writing the registration point set by the point setting part as a recorded point into a memory, and writing the registration image stored in the capture processing part as a recorded image corresponding to the recorded point into said memory, thereby recording said registration point and said registration image is said memory; a point calling part for reading out the recorded image and the recorded point from said memory in response to a given calling instruction; and a memory interface detachably connected to a recording device having said memory, wherein when connection of said recording device to said memory interface is detected, said point recording part writes the registration point and the registration image into said memory through said memory interface, when connection of said recording device to said memory interface is detected, said point calling part reads out the registration point and the registration image from said memory through said memory interface, and said point setting part sets the recorded point and the recorded image read out from said, memory by said point calling part, as the registration point and the registration image, respectively.
