Image processing apparatus having an image synthesis unit that generates synthesized image data depending on an object brightness, and related image-pickup apparatus

摘要

An image processing apparatus includes a memory that stores instructions, and one or more processors that execute the instructions to cause the image processing apparatus to function as, among other things, an image synthesis unit configured to synthesize first image data acquired by a first acquisition unit and second image data acquired by a second acquisition unit based on an object brightness, so that the first image data is selected in an area in which the object brightness is a first value that is greater than a threshold value, and the second image data is selected in an area in which the object brightness is a second value that is less than the threshold value, and to generate synthesized image data of the first image data and the second image data.
