SPATIAL INFORMATION DETERMINING APPARATUS

摘要

A spatial information determining apparatus capable of precisely determining information of a target space. This apparatus comprises a plurality of photoelectric converting parts that receive a reflected light from a space to which a flash light is irradiated; a charge storing part formed, on each photoelectric converting part, by applying a control voltage to a plurality of electrodes provided on each photoelectric converting part; control means for controlling the number of electrodes, to which the control voltage is to be applied, such that the area of the charge storing part is different based on the flash period of the flash light; and an amplitude image generating part for generating an amplitude image having pixel values each of which is the difference between the charge stored by a charge storing part during the light up of the flash light and the charge stored by another charge storing part during the light out of the flash light. ® KIPO & WIPO 2007
