Abstract:
An image processing apparatus includes a processing unit configured to execute image processing on an image signal; a filtering unit configured to execute filtering processing; and a changing unit configured to, in a case where a range of a value which a predetermined color component of the image signal can take is changed from a first range to a second range narrower than the first range by the image processing, change the value of the predetermined color component of the filtered image signal based on the first range and the second range.
