Method and apparatus for recording/reproducing image information on/from removable medium
In an image recording/reproduction method for recording image information on a recording medium by using a computer, a verify mode is set into the OFF state when recording image information on said recording medium. In addition, use as a write or read region a specified region of the recording medium which is greater than or equal to a unitary data size being handled during error correction processing to be performed when writing or reading image information on or out of said recording medium. Additionally, upon reading of image information from the recording medium, any image information that has experienced read errors will never be read again.
1. An image recording method for recording image information on a recording medium, comprising the steps of:
inputting the image information;
initializing the recording medium;
preparing an image file region on the recording medium by an operating system;
recording the image information on the image file region on a single frame unit basis,
wherein the step of initializing includes a step of executing at least one of a substep of setting not to verify whether or not a recording processing has been done successfully, a substep of setting not to retry the recording processing and a substep of setting to turn-off an automatic defect exchange function of the recording, and
wherein the step of preparing an image file region includes a substep of detecting a file size of the image information from input information of the image information and a substep of at first changing once a size of the image file region of the recording medium based on the detected file size;
reading, on a single frame unit basis, the image information recorded on the recording medium; and
sequentially displaying on a monitor the image information read on the single frame unit basis,
wherein when a failure has occurred in reading of one frame of the image information in the step of reading, the one frame is not read again, and the image information of a frame just before the one frame is continued to be displayed on the monitor without displaying the image information of the one frame;
a recording region selecting substep of selecting only a recording region capable of being handled on a unit of adding error correction codes upon recording, among the image file region prepared on the recording medium in the step of preparing an image file region; and
an image information recording substep of recording, on the recording region thus selected, the image information of one or plural frames at every recording region of one or a plurality of the units each being the unit of adding error correction codes,
wherein the recording region selecting substep includes a substep of, as to each of physically continuous regions existing within the recording region thus selected, calculating a start sector by a round-up calculation using a multiple of the unit of adding error correction codes and calculating an end sector by a round-down calculation using a multiple of the unit of adding error correction codes.
2. An image recording apparatus for recording image information on a recording medium, comprising:
an inputting unit which inputs the image information;
an image recording control portion which has an initializing unit of initializing the recording medium and a preparing unit of preparing an image file region on the recording medium by an operating system;
a recording unit which records the image information on the image file region on a single frame unit basis,
wherein the initializing unit includes at least one of a function of setting not to verify whether or not a recording processing has been done successfully, a function of setting not to retry the recording processing and a function of setting to turn-off an automatic defect exchange function of the recording, and
wherein the preparing unit includes a function of detecting a file size of the image information from input information of the image information and a function of at first changing once a size of the image file region of the recording medium based on the detected file size;
an image information reproducing unit which includes a unit of reading, on a single frame unit basis, the image information recorded on the recording medium, and a unit of sequentially displaying on a monitor the image information read on the single frame unit basis,
wherein even when a failure has occurred in reading of one frame of the image information in the step of reading, the one frame is not read again, and the image information of a frame just before the one frame is continued to be displayed on the monitor without displaying the image information of the one frame, and
wherein the recording unit includes a recording region selecting unit of selecting only a recording region capable of being handled on a unit of adding error correction codes upon recording, among the image file region prepared on the recording medium by the preparing unit; and
an image information recording unit of recording, on the recording region thus selected, the image information of one or plural frames at every recording region of one or a plurality of the units each being the unit of adding error correction codes,
wherein the recording region selecting unit includes a unit of, as to each of physically continuous regions existing within the recording region thus selected, calculating a start sector by a round-up calculation using a multiple of the unit of adding error correction codes and calculating an end sector by a round-down calculation using a multiple of the unit of adding error correction codes.
