Abstract

An image recording apparatus includes: a recording process section recording an image on a recording medium; an output process section outputting the image; and a control section multiplexing information on timing for starting the recording of the image with the image output from the output process section before the recording process section starts recording the image on the recording medium.

Claims

1. An image recording apparatus comprising:

a recording process section recording an image on first recording medium;

an output process section outputting the image to a second recording medium; and

a control section multiplexing recording start timing information of the image with the image output from the output process section before the recording process section starts recording the image on the first recording medium,

wherein the image is recorded on the second recording medium and the first recording medium in parallel and starting from a same frame, and the second recording medium also records identification information of the first recording medium, and

wherein the control section determines the start of recording the image on the first recording medium as the time when the first recording medium is driven at a predetermined speed.

2. An image recording apparatus according to claim 1, wherein the recording start timing information is information indicating a period to precede the recording of the image.

3. An image recording apparatus according to claim 2, wherein the recording start timing information is information indicating the number of frames of the image updated as time passes before the recording of the image is started.

4. An imaging recording apparatus according to claim 1, wherein the recording start timing information is information indicating that the apparatus is in a state of preparation for recording the image.

5. An image recording apparatus according to claim 1, wherein the output process section outputs a video signal in compliance with the serial digital interface standard as the output image.

6. An image recording apparatus according to claim 5, wherein the control section multiplexes the recording start timing information with a blanking period of the video signal.

7. An image recording apparatus according to claim 6, wherein the control section multiplexes the recording start timing information using a user bit area of time code information multiplexed with the blanking period.

8. An image recording apparatus according to claim 1, wherein the control section multiplexes information indicating the termination of the recording of the image with the image output from the output process section when the recording of the image on the first recording medium is terminated.

9. An image recording apparatus according to claim 1, further comprising an identification information reading section reading unique identification information set for the first recording medium for recording the image, the identification information being read from the recording medium,

wherein the control section multiplexes the read identification information with the image output from the output process section.

10. An image recording apparatus according to claim 9, wherein the control section generates time-divided information from the read identification information and multiplexes the time-divided information with the image output from the output process section.

11. An image recording control method comprising:

recording an image on a first recording medium;

outputting the image to a second recording medium; and

multiplexing recording start timing information of the image with the output image before the recording of the image on the first recording medium is started,

wherein the image is recorded on the second recording medium and the first recording medium in parallel and starting from a same frame, and the second recording medium also records identification information of the first recording medium, and

wherein the multiplexing step determines the start of recording the image on the first recording medium as the time when the first recording medium is driven at a predetermined speed.

12. An image recording apparatus comprising:

an input process section extracting recording start timing information multiplexed with an input image, the recording start timing information indicating timing for starting the recording of the image at an image output apparatus which has output the image, the start of recording the image at the image output apparatus being represented by the time when the image output apparatus is driven at a predetermined speed;

a recording process section recording the input image in a second recording medium; and

a control section controlling the operation of the recording process section based on the recording start timing information extracted by the input process section to record the input image in the second recording medium in parallel and starting from a same frame with the image recording operation of the image output apparatus,

wherein the image is also recorded in a first recording medium of the image output apparatus, and

wherein the image is recorded on the second recording medium and the first recording medium in parallel and starting from a same frame, and the second recording medium also records identification information of the first recording medium.
