1. An image processing apparatus comprising at least one memory and at least one processor function as:
a first determining unit configured to determine a first brightness range, which is included in a dynamic range of a first image and is higher than a predetermined brightness; and
a first converting unit configured to convert the first image into a second image, of which a dynamic range is narrower than the dynamic range of the first image, based on the determination result by the first determining unit, wherein
based on the first brightness range determined by the first determining unit, the first converting unit determines a second brightness range, which is included in the dynamic range of the second image and corresponds to the first brightness range.
