Image processing apparatus capable of performing conversion on input image data for wide dynamic range
There is provided an image processing apparatus capable of appropriately performing conversion processing using a lookup table on image data in an image format with a wide dynamic range. In the image processing apparatus, a system control unit sets a second dynamic range (display range) as a display target in a first dynamic range (input range) corresponding to an image format of input image data. A 1D-LUT data generation unit generates, based on the set second dynamic range (display range), first lookup table (LUT) data as a lookup table for performing first conversion processing on the input image data. A 3D-LUT data generation unit generates, based on the first dynamic range (display range), second lookup table (LUT) data as a lookup table for performing second conversion processing on image data obtained by the first conversion processing.
