During shooting, first encoded image data based on image data obtained by performing a simplified development process on RAW image data is recorded together with a RAW image, and afterward, second encoded image data based on image data obtained by performing a high-quality development process on the RAW image data is generated and recorded. By estimating the data amount of the second encoded image data during shooting and reflecting an area based on this data amount on management information of the recording medium as an area for recording the second encoded image data, the area in the recording medium is ensured.
