High frame rate, low depth noise ToF sensor
・ In-pixel analog memory array and sub-frame integration
・Frame rate : -10kfps*1, Depth noise : <1.3%*2
*2 at HP mode, 0.4-4.2m
Overview
・ Recently, ToF sensors that can measure the distance from an object are attracting attention in various fields such as automobiles, robots, and sensor.
・ However, conventional ToF sensors have a issue that it is difficult to improve both characteristics because there is a trade-off between frame rate and depth noise.
・ Therefore, this work has successfully solved the above issue by with in-pixel analog memory array for each image sensor and sub-frame integration.
・ This work achieved up to 10kfps at HS mode and depth noise is less than 1.3% at HP mode(0.4-4.2 m).
・ This work shows higher characteristics than conventional ToF sensors, and therefore, it is expected to be applied to autonomous driving sensors, autonomous running robots, factory automation (FA), drones, VR/AR, etc.
