CONTROL DEVICE AND CONTROL METHOD
Document Type and Number:
Japanese Patent JP2018101083
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique capable of improving light detection efficiency and feedback control efficiency.SOLUTION: A control device controls display by a display device comprising a plurality of light source units, an optical sensor, and a temperature sensor. The control device comprises: controlling means for controlling light emission of each light source unit on the basis of input image data; selecting means for selecting any of the plurality of light source units as a target light source unit; determining means for determining whether light from the target light source unit can be detected by the optical sensor from light emission of the target light source unit on the basis of the input image data; first acquiring means for acquiring a light detection value corresponding to the light from the target light source unit from the optical sensor; and second acquiring means for acquiring a temperature detection value corresponding to a temperature of the target light source unit from the temperature sensor. The selecting means determines a preferential light source unit in preference to other light source units or frequently selected as the target light source unit on the basis of determination results of the determining means and change in the temperature detection value.SELECTED DRAWING: Figure 1
