<p>PURPOSE: To surely detect an object instructed by an operator. CONSTITUTION: By image data from an image data memory 76 and data on the number and position of the object to the images outputted by an object control part 68, a liquid crystal unit 14 is driven through a driver 74 and a picture composed of the images and the objects is formed on the screen. When the operator processes an instruction switch 36, signals including the brightness and darkness state of the object from an instruction device 12 are inputted through the SW judgement part 62 of a PC 18 to a brightness and darkness judgement part 64, brightness and darkness judgement is started in the brightness and darkness judgement part 64 and the brightness of the respective objects is made to fluctuate by the object control part 68. Along with the brightness fluctuation of the objects, the instructed object is decided based on the brightness detected by a photosensor in the brightness and darkness judgement part 64 and a processing (screen changeover), corresponding to the decided object is executed by an object corresponding processing part 66.</p> |
