Image processing apparatus and image processing method

An apparatus for processing an image, the apparatus comprising at least one processor and/or at least one circuit to perform operations as following:

• a selecting unit configured to select one characteristic among a plurality of characteristics including a first characteristic corresponding to SMPTE ST 2084 (PQ);
• and
• a converting unit configured to convert an image to a false color image relating brightness of the image, on a basis of information in which brightness and color are related to each other, such that the image corresponding to each of sub-ranges of brightness is converted into each of different colors of the false color image, wherein
• brightness levels included in each of the sub-ranges are higher than brightness levels included in range of brightness corresponding to SDR, wherein
• in a case where a characteristic selected by the selecting unit is a first characteristic, the converting unit converts the image to the false color image on a basis of first information, and
• in a case where the characteristic selected by the selecting unit is a second characteristic, the converting unit converts the image to the false color image on a basis of second information which is different from the first information.

A method for processing an image, the method comprising:

• a selecting step of selecting one characteristic among a plurality of characteristics including a characteristic corresponding to high dynamic range (HDR);
• and
• a converting step of converting the image to a false color image for identifying brightness of the image by colors, according to a relationship, which corresponds to the selected characteristic, between brightness and color such that the image corresponding to each of sub-ranges of brightness is converted into each of different colors of the false color image, wherein
• in the relationship, each of the sub-ranges of brightness is related to each of different colors from each other, and brightness levels included in each of the sub-ranges are higher than brightness levels included in range of brightness corresponding to SDR.
