Abstract: PURPOSE: A driving method of a three-dimensional image sensor is provided to hold the mode of the three-dimensional image sensor to a low-power standby mode when the displacement of subjects is not detected. CONSTITUTION: A three-dimensional (3D) image sensor generates a two-dimensional (2D) image in a low-power standby mode and detects the displacement of subjects (S100). If the displacement of the subjects is detected in the 2D image, a controller of the 3D image sensor converts the mode of the 3D image sensor into a 3D operation mode in which power is more consumed than the low-power standby mode (S200). The 3D image sensor generates a 3D image in the 3D operation mode and recognizes the motion of the subjects (S300). [Reference numerals] (AA) Start; (BB) End; (S100) Generate a two-dimensional (2D) image in a low-power standby mode and detect possible displacement of subjects; (S200) Convert the mode of a 3D image sensor into a 3D operation mode if the displacement of the subjects is detected in the 2D image; (S300) Generate a 3D image in the 3D operation mode and recognize the motion of the subjects; (S400) Convert the 3D image sensor into the low-power standby mode when the motion recognition process ends

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.
