Abstract
An information device operation apparatus includes an image capturing device, an illumination device, a controller, image storage device, operation object extracting device, detection device, and signal output device. The image storage device stores a plurality of images that are acquired by the image capturing device under a plurality of illumination intensity conditions. The operation object extracting device extracts the operation object by comparing the plurality of images. The detection device detects at least one of a predetermined shape and a movement of the operation object that is extracted by the operation object extracting device. The signal output device outputs a signal to the target device, the signal corresponding to the at least one of the predetermined shape and the movement of the operation object detected by the detection device.
