An image capturing device (100) is provided with: an image capturing unit (102) which generates, by continuous image capturing, a plurality of pieces of image data which are continuous in the time direction; an image processing unit which corrects a compression rate of the image data on the basis of a correction factor for correcting the image data, and performs compression coding by use of an intra-frame predictive coding system; a data control unit (124) which stores the image data, which has been subjected to the compression coding, in an image storage unit; a current compression rate derivation unit (130) which derives a current compression rate which is an actual compression rate of the image data which has been subjected to the compression coding; a current compression rate holding unit (132) which holds a plurality of current compression rates continuous in the time direction; a subsequent compression rate prediction unit (134) which predicts a subject compression rate, which is a compression rate of image data to be subjected to the subsequent compression coding next time, from the plurality of current compression rates which are held, or from the plurality of current compression rates which are held and the compression rate of the image data to be subjected to the current compression coding this time; and a correction factor derivation unit which derives the correction factor on the basis of the subsequent compression rate.
