Patent ID: 10488654

Abstract:
Control of luminance of a light-emitting unit is enabled without separately providing a device for measuring the luminance of the light-emitting unit. A posture specifying unit specifies a posture of a user-controllable object including the light-emitting unit that emits light at luminance according to drive current, the posture specified based on a posture specifying image taken by a camera, the posture specifying image including an image of the light-emitting unit. A luminance information specifying unit specifies information indicating the luminance of the light-emitting unit based on a luminance specifying image taken by the camera that takes the posture specifying image, the luminance specifying image including an image of the light-emitting unit. A drive current control unit controls the drive current of the light-emitting unit based on the specified information indicating the luminance of the light-emitting unit.
