Image recorder
View Patent ↗A digital camera ( 10 ) includes an SDRAM ( 26 ). When 40 frames of image signals are accumulated in the SDRAM ( 26 ), a combined file including the 40 frames of image signals is created in a data area of a magnetooptical disk ( 36 ), and FAT information of the combined file is written into an FAT area of the magnetooptical disk ( 36 ). When a predetermined condition is satisfied, image data of the combined file is read out by each 1 frame, and an image file including the read image data is created in the data area of the magnetooptical disk ( 36 ), and the FAT information of the image file is written into the FAT area of the magnetooptical disk ( 36 ). Such the process is repeated for 40 times, and the combined file is later deleted.
1. An image recording apparatus, comprising:
a buffer memory into which M (M≧2, M is integer) images are fetched and stored in response to a fetching instruction;
a recording medium to record the M images fetched into the buffer memory;
a first-file creator for creating in a data area of said recording medium a first file including said M images stored in said buffer memory, said first file being created by writing said M images stored in said buffer memory from said buffer memory directly into said first file created in said data area of said recording medium as a form of combined file;
a first-managing-information creator for creating first managing information that manages said first file;
a reader for reading out, from said recording medium, N (N<M, N is integer) of the M images from said first file stored in said data area of said recording medium based on said first managing information when a predetermined condition that said fetching instruction is not received is satisfied;
a second-file creator for creating in said data area a second file including said N images read out by said reader, said second file being created by transferring said N images read out from said first file stored in said recording medium from said first file to said second file as a form of divided file; and
a second-managing-information creator for creating in a managing area of said recording medium a second-file managing information that manages said second file.
2. An image recording apparatus according to claim 1 , wherein
said recording medium is detachable, and
said first-file managing information creator creates in said managing area said first file managing information.
3. An image recording apparatus according to claim 1 or 2 , wherein
said second-file managing information creator creates said second-file managing information at every time that said second file is created once, and the apparatus further comprising a determining means for determining whether or not said predetermined condition is satisfied at every time that said second-file managing information is created once.
4. An image recording apparatus according to claim 1 or 2 , further comprising:
a fetcher for fetching said M of images into said buffer memory in response to said fetching instruction.
5. An image recording apparatus according to claim 1 or 2 , wherein
said recording medium is a disk recording medium having said data area and said managing area formed in a radius direction thereof, the apparatus further comprising,
a movable recording member moving between said data area and said managing area.
6. A digital camera comprising an image recording apparatus according to claim 1 or 2 .
7. An image recording apparatus according to claim 1 , wherein said M images included in said first file are compressed images, and said N images included in said second file are compressed images.
8. An image recording method for recording M (M≧2, M is integer) images that are fetched into a buffer memory in response to a fetching instruction in a recording medium, comprising:
creating a first-file in a data area of said recording medium, said first file including said M images stored in said buffer memory, said creating said first file including writing said M images stored in said buffer memory from said buffer memory directly into said first file created in said data area of said recording medium as a form of combined file;
creating first managing information that manages said first file;
reading out, from said recording medium, N (N<M, N is integer) of the M images from said first file stored in said data area of said recording medium based on said first managing information when a predetermined condition that said fetching instruction is not received is satisfied;
creating a second-file in said data area, said second file including said N images read out by said reader, said creating said second file including creating a form of divided file by transferring said N images read out from said first file stored in said recording medium from said first file to said second file; and
creating second file managing-information that manages said second file in a managing area of said recording medium.
