During capturing, image data obtained by applying a simplified development process to RAW image data is recorded together with a RAW image. Afterward, image data obtained by applying a high quality development process to the RAW image data is generated, and this image data replaces the image data obtained by the simplified development. During capturing, a plurality of pieces of image data are generated by using a plurality of different development parameters for RAW image data, and recorded in association with the RAW image data. The development parameter corresponding to image data selected by the user is decided as a development parameter used for the subsequent high quality development process for the RAW image data, thereby facilitating the setting of the development parameters of the RAW image.
