Abstract
An image recording apparatus includes an image sensor. Image data of an object imaged by the image sensor is recorded on a recording medium to which an FAT system is adopted. A recording area of the recording medium is divided into a plurality of clusters, and available clusters can be dispersedly distributed. When formatting the recording medium, a CPU increases a cluster size as a capacity of the recording medium is larger, or the recordable number of frames of the recording medium is greater.
Claims18
An image recording apparatus that records image data on a recording medium in which a recording area is divided into a plurality of unit areas and available unit areas can be dispersedly distributed, comprising:
- a detector for detecting a capacity of said recording medium;
- and
- a setter for setting each of said unit areas to a first unit area size when the capacity detected by said detector is one of at least equal to and greater than a first recording medium capacity size, and for setting each of said unit areas to a second unit area size when the capacity detected by said detector is less than the first recording medium capacity size, the first unit area size being greater than the second unit area size.
An image recording method that records image data on a recording medium in which a recording area is divided into a plurality of unit areas and available unit areas can be dispersedly distributed, comprising the steps of:
- (a) detecting a capacity of said recording medium;
- and
- (b) setting each of said unit areas to a first unit area size when the capacity detected in said step (a) is one of at least equal to and greater than a first recording medium capacity size;
- and
- (c) setting each of said unit areas to a second unit area size when the capacity detected in said step (a) is less than the first recording medium capacity size, the first unit area size being greater than the second unit area size.
An image recording method that records image data on a recording medium in which a recording area is divided into a plurality of unit areas and available unit areas can be dispersedly distributed, comprising the steps of:
- (a) detecting the capacity of said recording medium;
- (b) calculating a recordable number of frames of said recording medium on the basis of the capacity detected in said step (a);
- (c) setting each of said unit areas to a first unit area size when the recordable number of frames calculated in said step (b) is one of at least equal to and greater than a first threshold number of recordable frames;
- (d) setting each of said unit areas to a second unit area size when the recordable number of frames calculated in said step (b) is less than the first threshold number of recordable frames and is one of at least equal to and greater than a second threshold number of recordable frames;
- and
- (e) setting each of said unit areas to a third unit area size when the recordable number of frames calculated in said step (b) is less than the second threshold number of recordable frames, the first unit area size being greater than the second unit area size, and the second unit area size being greater than the third unit area size, the first threshold number of recordable frames being greater than the second threshold number of recordable frames.
