Patent ID: 8018502

Claim:
An image recording device that compresses a captured image and records the captured image to a recording medium, the captured image being captured at a second frame rate higher than a first frame rate, and the recording medium being removable from said image recording device, said image recording device comprising: a reference clock generation unit configured to generate a reference clock; a first compression unit configured to generate first compressed image data by compressing a first picture that is included in pictures in the captured image and that is equivalent to the image captured at the first frame rate; a second compression unit configured to generate second compressed image data by compressing a second picture that is included in the pictures in the captured image except the first picture; a first timestamp generation unit configured to generate a first timestamp indicating a time for presentation of the first picture with reference to the reference clock; a second timestamp generation unit configured to generate a second timestamp indicating a time for presentation of the second picture with reference to the reference clock; a first assignment unit configured to assign the first timestamp to the first compressed image data; a second assignment unit configured to assign the second timestamp to the second compressed image data; and a recording unit configured to record, to the recording medium, (i) the first compressed image data assigned with the first timestamp by said first assignment unit and (ii) the second compressed image data assigned with the second timestamp by said second assignment unit.
