The invention provides a device and method for reading compact storage image data. The device comprises a reading control unit, a write row cache control unit, a row cache unit, a reading address jumping unit and a configuration information storage unit. The method comprises the steps of: configuring the configuration information storage unit, opening bit configuration of a circuit working switch, reading the address jumping unit, calculating a reading address of each reading action, and sending the reading address to the reading control unit; reading data of a word by the reading control unit, and sending the read data to the write row cache control unit; judging which part of the read data is written in the row cache unit by the write row cache control unit, and according to the judgment result, and writing all or part of the read data into the row cache unit according to the judgment result for the displaying of external images or the use of processing circuits; and circulating in such way until all the rows of the images are completely read. The device and method are used for controlling the reading of a compact image storage mode, and the control process is simple and effective.
