摘要： A plurality of types of interchangeable lenses having mutually different optical parameters required for identifying the optical correction values can be attached to the image capture apparatus. First, predetermined optical parameters are obtained regardless of what type of interchangeable lens is attached. Furthermore, in the case where the type of the attached interchangeable lens is a type that requires different optical parameters than the predetermined optical parameters for identifying the optical correction value, the necessary optical parameters are obtained. The optical correction value is identified based on the type of the attached interchangeable lens using the predetermined optical parameters, other optical parameters, and so on, and optical correction is then carried out.

摘要： An image processing apparatus capable of properly suppressing coloring caused by image restoration processing. A feature amount of a color of pixels in RAW image data obtained through photographing via an image pickup optical system is calculated as a first color feature amount. Restoration processing is performed on the RAW image data using a restoration filter for improving image quality degraded due to aberration of the image pickup optical system to thereby generate restored image data. A feature amount of a color of pixels in the restored image data is calculated as a second color feature amount. A pixel value of the restored image data is corrected according to a result of comparison between an amount of change in the second color feature amount with respect to the first color feature amount and a threshold value which is set based on a predetermined condition.

摘要： An image processing apparatus capable of properly suppressing coloring caused by image restoration processing. A feature amount of a color of a pixel in an image before restoration processing is calculated as a first color feature amount. Image restoration processing is performed on the image using an image restoration filter. A feature amount of a color of a pixel in an image after restoration processing is calculated as a second color feature amount. High-frequency components included in the first color feature amount and the second color feature amount are attenuated according to a photographing condition at the time of photographing the image. Pixel values of the image after restoration processing are corrected based on the first color feature amount and the second color feature amount of which the high-frequency components are attenuated.
