Abstract
An image file recording apparatus of the present invention records, into a recording medium, an image file that includes image data and header information which has variable-length information, and includes: a JPEG compression unit which generates image data; a microcomputer which determines a first address indicating the head of the image file and a second address obtained by adding a fixed value to the first address; and an APP portion writing unit 205 which writes, without going through a memory, the image data into an area, in the recording medium, starting from the second address.
Claims18
An image file recording apparatus which records, into a recording medium, an image file including image data and header information which has variable-length information, said apparatus comprising:
- a generation unit operable to generate image data;
- a determination unit operable to determine a first address indicating a head of the image file, and a second address obtained by adding a fixed value to the first address;
- and
- a writing unit operable to write, without going through a memory, the image data into an area, in the recording medium, starting from the second address.
An image file recording method for recording, into a recording medium, an image file including image data and header information which has variable-length information, said method comprising:
- generating image data;
- determining a first address indicating a head of the image file, and a second address obtained by adding a fixed value to the first address;
- and
- writing the image data into an area, in the recording medium, starting from the second address, without going through a memory.
An image file recording method for recording, into a recording medium, an image file including image data and header information which has variable-length information, said method comprising:
- generating image data;
- creating header information with a fixed data size;
- and
- writing the header information and the image data into the recording medium so that an end position of the header information is followed by a start position of the image data.
