IMAGE DATA COMPRESSION PARAMETER VALUE CONTROLLING DIGITAL IMAGING DEVICE AND IMAGE DATA COMPRESSION PARAMETER VALUE DECISION METHOD

摘要

A compression device has one or more compression parameters. An image data generation device successively performs new test imaging and successively supplies new first type image data to the compression device. The compression device compresses at least two of the first type image data among the first image data successively supplied, with the different compression parameters. A processing device decides the parameter value to be used for the second type image data from the at least two first type image data which have been compressed with the different compression parameter values, according to a predetermined reference. Furthermore, the processing device sets the value of the compression parameter of the compression device as the value which has been decided.
