Title:
IMAGE PROCESSING DEVICE AND DISPLAY DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2017050636
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an image processing device and a display determination method capable of determining whether or not a display device can display an image at a brightness corresponding to each luminance level of input image data.SOLUTION: An image processing device 1 comprises: a first color gamut conversion unit 20 that converts an input image signal of an XYZ colorimetric system into an output image signal A2 of a linear RGB colorimetric system by using an inverse matrix of a matrix M having as a component a value obtained by normalizing an XYZ value obtained by measuring an image displayed on a display device of a determination target by a predetermined luminance value; and a determination unit 40 that, when a value of R, G, or B of the output image signal A2 is larger than 1, determines that the display device cannot display an image related to an input image signal A1 at a brightness corresponding to each luminance of the input image signal A1.SELECTED DRAWING: Figure 1
