Image processing apparatus, image processing method, and storage medium

An image processing apparatus comprising:

• a first calculation unit configured to calculate a first white balance correction value based on a pixel value in a divided region, among a plurality of divided regions into which first image data is divided, where a color evaluation value is within a predetermined color range;
• and
• a second calculation unit configured to calculate, if the first white balance correction value is at a high temperature side of a predetermined threshold value, a second white balance correction value for correcting white balance for second image data based on a pixel value in a divided region within a color range where a color range at a low temperature side of the predetermined color range is limited.

An image processing method executed by an image processing apparatus, the image processing method comprising:

• calculating a first white balance correction value for correcting white balance for image data based on a pixel value in a divided region, among a plurality of divided regions into which the image data is divided, where a color evaluation value is within a predetermined color range;
• and
• calculating, if the first white balance correction value is at a high temperature side of a predetermined threshold value, a second white balance correction value for correcting white balance for the image data based on a pixel value in a divided region within a color range where a color range at a low temperature side of the predetermined color range is limited.
