Abstract:
PURPOSE: A distance measurement device and an operation method are provided to accurately measure a distance with an object. CONSTITUTION: A distance measurement device (10) includes a timing controller (20), an optical module (40), and a distance sensor (30). A light source outputs an optical signal to an object. The distance sensor measures a set of distance information in response to a reflective light which is reflected from the object. The timing controller controls the operation timing of the distance sensor by transmitting an optical radiation control signal to the light source and transmitting an optical detection control signal to the distance sensor. The optical signal includes a plurality of sequences. A phase of a pulse is randomly changed per sequence.
Abstract:
PURPOSE: An image system capable of automatically calibrating a depth image is provided to control the phase of a light source control signal by correcting a phase array between a signal driving a pixel demodulated signal and a signal driving a light source modulating signal. CONSTITUTION: A light source (10) irradiates modulated light to a target object in response to a light source control signal. An image sensor (60) includes at least one pixel and generates a depth image from a pixel signal outputted from the pixel according to the light reflected from the target object. A delay compensation part (62) of the image sensor receives a light source signal receiving feedback from the light source to the image sensor. The delay compensation part controls the light source control signal by comparing the light source signal received feedback with a gate signal driving the pixel.
