Abstract
In a color sensor unit for use in a display device, a color measuring device for use in a display device, a display system and a display calibration method of the invention, a CPU is operable to calculate a luminance value or a chromaticity value substantially equivalent to that to be obtained by a measuring device having a light receiving angle smaller than a light receiving angle of a sensor, by correcting a luminance value or a chromaticity value measured by the sensor based on gradation information from the display device.
