Abstract
An image calibration method for use in an imaging system. The imaging system includes a projection device, a color detector and a processor. The image calibration method includes in an ambient light environment, the color detector taking a background luminance and an ambient measurement of a test image on a projection surface, and the processor generating a color appearance representation using the background luminance and the ambient measurement, in a darkroom environment, the color detector taking a darkroom measurement of a test image, and if a surround ratio is less than a predetermined threshold, the processor generating a target using the darkroom measurement and the color appearance representation, and the processor configuring a gamut of the projection device according to the target, and adjusting an image according to the gamut and the darkroom measurement, and the projection device projecting the adjusted image.
