Summary:An image processing device comprises an acquisition part for acquiring brightness of an input image having a color reproduction range wider than that of a recording device, a conversion part for performing a conversion process for acquiring a value included in the color reproduction range of the recording device with respect to the input image and acquiring the brightness of the image after conversion, and a correction part for correcting the brightness of the input image. The correction part performs correction on the brightness of the input image such that an intensity of correction for the color not included in the color reproduction range of the recording device is increased compared to the color included in the color reproduction range of the recording device on the basis of a conversion characteristic between the acquired brightness of the acquisition part and the acquired brightness of the conversion part. 화상 처리 장치는, 기록 장치보다도 넓은 색 재현 범위를 갖는 입력 화상의 휘도를 취득하는 취득 유닛; 입력 화상에 대하여, 기록 장치의 색 재현 범위에 포함되는 값을 취득하는 변환 처리를 행하고 변환 후의 화상의 휘도를 취득하는 변환 유닛; 및 입력 화상의 휘도를 보정하는 보정 유닛을 포함하고, 보정 유닛은, 취득한 휘도와 취득한 휘도 사이의 변환 특성에 기초하여, 기록 장치의 색 재현 범위에 포함되는 색보다도, 기록 장치의 색 재현 범위에 포함되지 않는 색에 대한 보정의 강도가 강해지도록, 입력 화상의 휘도에 대한 보정을 행한다.
