Abstract
An image processing apparatus includes a detection unit configured to detect a specific area from a captured image, and a determination unit configured to determine, based on the detected specific area, a light source color including a characteristic color by using a learning unit trained in advance by machine learning.
Claims11
An image processing apparatus comprising:
- one or more processors configured to function as following units:
- a detection unit configured to detect a specific area from a captured image;
- a first determination unit configured to determine, based on a color included in the detected specific area, a light source color including a characteristic color by using a learning unit trained in advance by machine learning;
- a first calculation unit configured to calculate a first white balance correction value corresponding to the light source color determined by the first determination unit;
- a second determination unit configured to determine the light source color based on a color of an area including an area other than the specific area;
- a second calculation unit configured to calculate a second white balance correction value corresponding to the light source color determined by the second determination unit;
- and
- a third calculation unit configured to calculate a third white balance correction value based on the first white balance correction value and the second white balance correction value.
