Image processing apparatus, image processing method, and storage medium
First Claim
1. An image processing apparatus that generates a combined image by performing gamma processing and combination processing for a plurality of images obtained by capturing images of the same image capturing-target scene under different exposure conditions, the image processing apparatus comprising:
- an acquisition unit configured to acquire adjustment parameters that adjust gamma characteristics applied to the gamma processing in accordance with a dynamic range of the image capturing-target scene;
a gamma processing unit configured to perform the gamma processing to which adjustment parameters acquired by the acquisition unit have been applied for the plurality of images; and
a combination unit configured to generate the combined image by performing the combination processing for the plurality of images for which the gamma processing has been performed by the gamma processing unit.
