Method and apparatus for recording and re-recording image data in a device having limited memory capacity
First Claim
1. An image re-recording method comprising the steps of:
- recording data representing at least one image obtained by photographing in a recording medium;
storing accompanying information received with regard to the data of each image having been recorded, by relating the accompanying information to the image data;
changing the accompanying information stored, as desired;
judging, based on the accompanying information, whether or not the data of each image are re-recorded as data having a smaller data size when a predetermined operation is carried out;
reading image data to be re-recorded sequentially from the recording medium, based on the judgment;
carrying out conversion processing such that the size of image data becomes smaller than the image data having been read; and
collectively re-recording the image data after the conversion in the recording medium.

Abstract
In the case where images photographed by a digital camera or the like are recorded in a recording medium at a predetermined resolution or compression rate upon photographing and the data representing the image are re-recorded therein after being read and resolution-converted or re-compressed, a target of re-recording can be specified by a simple operation and damage due an erroneous input can be minimized. A function is provided for setting accompanying information such as necessity of printing an image when the image is being replayed in a replay mode, for example. The information having been set is described in a tag of an image file and recorded together with the image. When a user shifts a mode to a re-recording execution mode, necessity of re-recording is judged based on the stored information having been set. A re-recording target image file is then read from a memory card and re-recorded therein after a resolution conversion or compression processing carried out on the image data.

8. An image recording method as claimed in claim 1 wherein the accompanying information is information showing the content of printing of the image data;
- and
the judgment is carried out based on the content of printing.

10. An image re-recording apparatus comprising:
-
photographed image recording means for recording data representing at least one image obtained by photographing in a recording medium;
accompanying information recording means for storing accompanying information received with regard to the data of each image having been recorded, by relating the accompanying information to the image data, the accompanying information recording means capable of changing the stored information, as desired;
re-recording necessity judging means for judging, based on the accompanying information, whether or not the data of each image are re-recorded as data having a smaller data size when a predetermined operation is carried out;
data reading means for reading image data to be re-recorded from the recording medium, based on the judgment;
data converting means for carrying out conversion processing such that the size of image data becomes smaller than the image data having been read; and
re-recording means for collectively re-recording the image data after the conversion in the recording medium. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
the re-recording necessity judging means judges that re-recording is unnecessary if printing is necessary or that re-recording is necessary if printing is unnecessary.
