CALIBRATION DEVICE, CONTROL METHOD OF CALIBRATION DEVICE, DISPLAY DEVICE AND CONTROL METHOD OF DISPLAY DEVICE

Japanese Patent JP2016122056

A

PROBLEM TO BE SOLVED: To accurately perform calibration to a display device capable of performing display in which consumption power is reduced by reducing a refresh rate under a prescribed condition.SOLUTION: A calibration device for performing calibration to a display device including a display panel for displaying an image with application of voltage to each pixel on the basis of image data and performing such control that voltage is not applied to the display panel in a region where a prescribed condition is established when the image data is updated, comprises: output means which outputs image data including a patch image to the display device; calibration means which acquires a colorimetric value of the display panel from a measuring instrument and performs calibration on the display panel on the basis of the acquired colorimetric value; and correction means which corrects the image data so that the prescribed condition is not established in the region displaying the patch image when the calibration is performed.SELECTED DRAWING: Figure 2
