Signal processor
First Claim
1. A signal processor for playing back an image signal including a plurality of image frames, comprising:
- a buffer memory for storing the image signal for output as a main image signal;
a point setting section for storing a position on a temporal axis of the main image signal as a registration point in response to a given capture command, said registration point corresponding to the capture command;
a playback control section for playing back the image signal by causing said buffer memory to output image frames following the registration point in response to a given playback command;
a video capture section for generating a registration image based on at least one image frame in a neighborhood of the registration point of the main image signal outputted from said buffer memory, and storing the registration image; and
an image superimposing section for superimposing the registration image onto the main image signal for display in a signal screen to generate a composite image signal,wherein said playback control section has a cue playback capability of temporarily stopping playback of the main image signal in response to a given standby command, and thereafter causing said buffer memory to output the image frame following the registration point in response to said playback command.
