IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To prevent image compression processing from being performed by an unnecessarily high compression rate and obtain the high quality image after the compression processing.SOLUTION: An imaging device 100 comprises: a first compression control unit 5b which controls compression processing to be performed on a piece of non-compressed image data by a first compression rate; a data size calculation unit 5c which calculates data size of the image data when a predetermined ratio of the image data is compressed in the compression processing: a first determination unit 5d which determines whether the calculated data size exceeds a predetermined determination value in the compression processing; a second determination unit 5f which, when the predetermined ratio of the image data is compressed, determines whether it is possible to start and complete re-compression processing on the image data by a second compression rate that is higher than the first compression rate within a predetermined time period; and a second compression control unit 5g which, when the data size exceeds the predetermined determination value and the second determination unit 5f determines that it is possible to perform the re-compression processing by the second compression rate, controls the re-compression processing to be performed on the processing target image data by the second compression rate.
