Time-of-flight (TOF) light sensor of TOF camera for use in three-dimensional-TOF (3D-TOF) camera system, has light transit time pixels that includes different color filters which are distributed in predetermined pattern on sensor area

摘要

The light sensor (22) has multiple light transit time pixels that is configured for demodulating the received modulated light (Sp2). The light transit time pixels are provided with different color filters which differ in the spectral transmittance in a visible light range. Each color filter comprising transparency for a portion of the infrared light spectrum of the modulated light, is distributed with the spectral transmittance in the red, green and blue lights in a predetermined pattern on the sensor area.
