摘要： The low power image sensor includes: an image sensing unit which senses light from an object, converts the light into an electric signal, and outputs the electric signal; a comparing unit which receives an electric signal from the image sensor, compares a voltage level of the electric signal with a reference voltage, and outputs an image signal as a 1 bit signal per pixel; and an effective image adjuster which compares bit value distribution of an image signal output from the comparing unit with a preset effective range, and adjusts the reference voltage to output an effective image. Further, an optical pointing device includes: an image sensor which senses light from an object and outputs an image signal; and a motion computing unit which receives the image signal and compares before and after images to calculate a motion vector.

摘要： A remote control transceiver is described. The remote control transceiver reduces costs by simplifying a structure of a conventional space movement remote controller including an acceleration sensor, a microprocessor, a radio transmitting unit, and a radio receiver. A grid pattern formed by a light emitting diode (LED) and an optical system of a transmitter is determined by an infrared sensor of a receiver to discern space movement location information of the transmitter. The remote control transceiver includes a remote control transmitter and a remote control receiver. The remote control transmitter includes a key input unit for receiving commands, an LED driver for controlling the operation of an LED in response to a command signal generated from the key input unit, and a pattern generator for generating a grid pattern using light generated from the LED. The remote control receiver detects a moving direction and a moving distance using the grid pattern received from the remote control transmitter, and generates location information corresponding to the moving direction and distance.
