Abstract
The invention provides an image taking apparatus for shortening image taking time and obtaining a high quality image by preventing deterioration of the S/N ratio. A digital camera that performs image taking for generating image signals by capturing, with a CCD, object light sent via an image taking optical system includes: a shading correction section performing shading correction by adjusting gain depending on respective positions on the CCD; a scene determination section determining that a scene just shot is to be corrected if the scene just shot includes a uniform region with a predetermined or more area and a predetermined or higher bright ness; and a shading correction control section causing, if the scene just shot is determined by the scene determination section to be a scene to be corrected, the shading correction section to perform shading correction on an image signal obtained by image taking just performed.
