Abstract

An image recording apparatus includes a JPEG CODEC that produces JPEG data by compressing image data. Markers SOI and EOI are embedded in produced JPEG data, and such the JPEG data is recorded into a magnetooptical disk by a disk drive. Upon completion of recording a plurality of frames of the JPEG data, each frame of the JPEG data is read out into a work area of an SDRAM, and the markers SOI and EOI are detected from the read JPEG data. Index information of each frame of the JPEG data is generated on the basis of the detected markers SOI and EOI. Generated index information is recorded following a last frame of the JPEG data.

Claims

1. An image recording apparatus for recording a plurality of still image signals into a recording medium in a state that markers are added to the respective signals, comprising;

a detector for detecting the markers recorded in said recording medium;

a generator for generating recording location information of the plurality of still image signals on the basis of the markers detected by said detector; and

a recorder for recording into said recording medium the recording location information generated by said generator in association with the plurality of still image signals.

2. An image recording apparatus according to claim 1, wherein the markers are added to a head and a last of the respective still image signals, and the recording location information includes a head address and a size of the respective still image signals.

3. An image recording apparatus according to claim 1, wherein said detector includes a reader for reading out the still image signals recorded into said recording medium onto an internal memory, and a marker detector for detecting the markers by examining said internal memory.

4. An image signal recording method, comprising steps of:

(a) recording a plurality of still image signals into a recording medium in a state that markers are added to the respective signals;

(b) detecting the markers recorded in said recording medium;

(c) generating recording location information of said plurality of still image signals on the basis of the markers detected in said step (b); and

(d) recording into said recording medium the recording location information generated in said step (c) in association with the plurality of still image signals.
