Solid-state imaging device, digital camera, and image processing method

A digital camera comprising;

• an imaging optical system that catches light from an object, and forms an object image;
• and
• a solid-state imaging device that transforms light caught by the imaging optical system into signal charge, and captures the object image,
• wherein the solid-state imaging device includes
• an image sensor that captures the object image, and
• a resolution reconstruction circuit that performs a resolution reconstruction process on the object image,
• wherein the resolution reconstruction circuit performs a filtering process based on a filter as the resolution reconstruction process, and
• wherein the filter has a filter property of reducing a modulation transfer function relative to an ideal modulation transfer function in a frequency range of a frequency higher than a frequency set in advance.
