発明の名称 (英語) RANGE IMAGE MEASURING APPARATUS
発明の概要(英語) This range image measuring apparatus 1 is provided with: imaging units 3 in which are arrayed a plurality of pixels Xijeach having a photoreception unit 12 for converting pulse light emitted from a light source 2 and reflected by a target object O to an electrical charge, in response to incidence of the pulse light, an electrical charge accumulation unit 13 for accumulating electrical charges transferred from the photoreception unit 12, a charge expulsion unit 14 for expelling electrical charges transferred from the photoreception unit 12, and a gate electrode 15 for controlling transfer of electrical charges from the photoreception unit 12 to the electrical charge accumulation unit 13 or to the charge expulsion unit 14, according to a plurality of control patterns P for controlling the charge transfer destination; and a control means 4 and a signal-processing circuit 5 for, on the basis of the plurality of control patterns P and a plurality of electrical charge quantities Q accumulated in the electrical charge accumulation unit 13, estimating the pulse light flight time from the light source 2 to the photoreception unit 12.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional, pulsed light is irradiated to the object, the reflected light pulses of light can be detected by measuring the time-of-flight distance measuring device has been known. For example, Patent Document 1 is a distance measurement apparatus described, the pulse width sufficiently shorter than the response time of the light receiving unit onto the object to the pulsed light is irradiated to the control of the timing, with reference to the timing of irradiation of the 2 types of the control of the phase pulse voltage applied to the gate voltage. Thus, in a light receiving part of the pulsed light incident in the conversion of the electric charge, is modulated in the charge storage unit and stored there. Then, these 2 kinds of phase-modulated by a pulse voltage of 1 and the second charge 2, the first and the second charge reading unit 1 read out as an electric signal of 2, 2 1 of the first and second calculation section calculates the first distance to the object according to an electric signal is calculated. Thus, the range of the object image is generated.
