Patent ID: 8670654

Claim:
An image capturing device, comprising: an image capturing unit generating a plurality of pieces of image data which are continuous in the time direction by continuous image capturing; an image processing unit correcting a compression rate of the image data on the basis of a correction factor for correcting the image data, and performing compression coding by use of an intra-frame predictive coding system; a data control unit storing the image data, which has been subjected to the compression coding by the image processing unit, in an image storage unit; a current compression rate derivation unit deriving a current compression rate which is an actual compression rate of the image data which has been subjected to the compression coding by the image processing unit; a current compression rate holding unit holding a plurality of current compression rates derived by the current compression rate derivation unit and being continuous in the time direction; a subsequent compression rate prediction unit predicting a subject compression rate, which is a compression rate of image data to be subjected to the compression coding next time, on the basis of the plurality of current compression rates held by the current compression rate holding unit, or on the basis of the plurality of current compression rates held and the compression rate of the image data to be subjected to the compression coding this time; and a correction factor derivation unit deriving the correction factor on the basis of the subsequent compression rate predicted by the subsequent compression rate prediction unit.
