Abstract:
1. An image recording system, comprising: a flash memory comprising a control unit and a plurality of memory blocks and storing a faulty block detection procedure, wherein some of the memory blocks are set as first blocks, and the other memory blocks are set as second blocks, a ratio of a quantity of the first blocks to a quantity of the second blocks is set according to a total capacity of the flash memory, and a total capacity and the quantity of the first blocks and a total capacity and the quantity of the second blocks are reset in a flash memory arrangement procedure; and an image recorder connecting to the flash memory and comprising a processing unit, a capturing unit and a storage unit, the capturing unit being configured to capture an object to output a target image file, and the processing unit connecting to the capturing unit and the storage unit and being configured to write the target image file into the first blocks; wherein when the target image file is being written into the flash memory, the control unit performs the faulty block detection procedure to detect whether a first block into which the processing unit tries to write a piece of data of the target image file is faulty; and when the first block is faulty, the control unit selects normal one of the second blocks and writes the piece of the data of the target image file into the selected second block instead of the first block; and wherein the second blocks are back-up blocks for the first blocks, and the total capacity of the flash memory does not include a total capacity of faulty block.
