Abstract
An image processing apparatus acquires image data and first information relating to a maximum luminance value of an output dynamic range of the image data. The apparatus then applies, to the image data, processing in which a luminance value of the image data and a first value based on the first information are used. In a case in which the image data is encoded in a first numerical range and the first information is encoded in a second numerical range that is different from the first numerical range, the apparatus applies the processing to the image data after converting the image data, the first information, or the first value so that the image data and the first value have values if the image data and the first value would have been encoded in a same numerical range.
