Abstract:
A coding device having a coder for coding image data, the coding device comprising:a first setting section for setting therein a predetermined amount of image data to be coded; a storage section for storing a plurality of parameters; a generating section for generating a combination of parameters using the parameters stored in the storage section; an estimation section for estimating a coding amount by setting the combination of parameters generated by the generating section in the coder and coding the predetermined amount of image data set by the first setting section; a second setting section for setting in the coder the combination of parameters, which provides a minimum coding amount, on the basis of an estimation result obtained by the estimation section; and a control section for coding all the image data to be coded, when the second setting section has set in the coder the combination of parameters, which provides the minimum coding amount.
