Abstract
An optical remote controller includes a movable infrared ray transmitter, a plurality of light receiving modules, and a received light signal selector for selecting the earliest sensed one from the light signals received by the light receiving modules. The signal selector includes a clock signal generator, first to third mask signal generators to generate invalidation signals, received light signal mask circuits to invalidate received signals, a mask release signal generator to measure an invalidation time period, and an encoder to sense termination of each unit of transmission information. A camera is attached rotatably in vertical and horizontal directions on a fixed support plate. The support plate includes a plurality of infrared ray receiving elements. According to a moving command of an optical remote control signal received by the elements, an optical remote controller vertically and horizontally drives the camera and directs the camera to the arrival direction of the remote control signal.
