Patent ID: 7406253

Claim:
A shot-image-recording system comprising: a shooting device for shooting an object; and a signal-recording device for recording in a recording medium an image signal obtained by shooting the object with the shooting device, wherein said shooting device comprises: shooting means for generating from a shot image a first image signal having a shooting frame rate; frame-addition-processing means for adding one or more frames to the first image signal generated by the shooting means to obtain a second image signal having an output frame rate in which the shot image is contained at a variable frame rate and outputting said second image signal having the output frame rate and a validity signal indicating a frame of the first image signal having the variable frame rate in said second image signal having the output frame rate; and shooting control means for controlling operations of the shooting means and the frame-addition-processing means on the basis of a frame-rate-setting signal, to vary the shooting frame rate and/or vary the number of frames to be added to the first image signal so that the variable frame rate may be set to a frame rate based on the frame-rate-setting signal, and wherein the signal-recording device comprises: storage means for storing the second image signal temporarily; storage control means for selecting an image signal of the image having the variable frame rate from among the second image signal having the output frame rate on the basis of said validity signal and storing it in the storage means; recording means for recording a signal in the recording medium; and recording control means for recording the second image signal stored in the storage means in the recording medium intermittently at a predetermined recording frame rate in accordance with a signal quantity of the second image signal stored in the storage means.
