IMAGE CAPTURING APPARATUS AND IMAGE CAPTURING METHOD

An image capturing apparatus includes: a captured still image data generating section that converts captured light into an electrical signal and generates captured still image data from the electrical signal; a recording section that records the captured still image data onto a recording medium; a free-capacity recognizing section that recognizes a free capacity on the recording medium; a prescribed-maximum-possible-record-count calculating section that calculates a prescribed maximum possible record count according to the free capacity; and a parameter determining section that determines a parameter set on the captured still image data generating section to adjust a data size of the captured still image data. The parameter determining section determines the parameter so that the captured still image data is adjusted to a data size that allows recording of captured still image data equal to the prescribed maximum possible record onto the recording medium while making maximum use of the free capacity.
