An image capturing apparatus is provided having an image capturing device, an image compressing device, a recording device, a definition calculating device, and a residual recordable number calculating device. The image capturing device outputs a captured image. The image compressing device compresses the captured image using flexible compression. The recording device records the compressed captured image into a memory medium. The definition calculating device calculates a definition by summing the absolute value of higher frequency components in the compressed captured image before the higher frequency components are rounded off. The residual recordable number calculating device calculates a residual recordable number of images in the memory medium using the definition of a standard image, the file size of a standard image, and a residual recordable amount of the memory medium.
