Abstract
An image processing device includes an image input section configured to receive input of an image, a chromatic value acquisition section configured to obtain a chromatic value with respect to each of pixels of the image, an RGB conversion section configured to convert the chromatic value of each of the pixels of the image into an unnormalized linear RGB value expressed by a linear RGB value based on a characteristic of a display which outputs the image, a normalization section configured to divide the unnormalized linear RGB value by a modulus higher than a maximum value of linear RGB values which express displayable colors of the display to thereby generate a normalized linear RGB value when the unnormalized linear RGB value of at least one of the pixels is higher than the maximum value, an outputting RGB conversion section configured to convert the normalized linear RGB value into a display outputting RGB value, and an output section configured to output the display outputting RGB value to the display.
