Abstract: An image processing method includes the operations of receiving N×N raw data from an N×N sub pixel array including a plurality of first exposure pixels and second exposure pixels having different exposure times, respectively; obtaining a difference value between a value obtained by normalizing an interpolated value of the first exposure pixels and an interpolated value of the second exposure pixels for each channel in the N×N sub pixel array based on the N×N raw data; setting a mismatching value to a maximum value among difference values obtained for the respective channels; and setting a corrected value of a central pixel in the N×N sub pixel array based on the N×N raw data and based on the mismatching value and a threshold value.

Abstract translation: 一种图像处理方法包括分别从包括多个第一曝光像素的N×N子像素阵列和具有不同曝光时间的第二曝光像素接收N×N个原始数据的操作; 基于所述N×N个原始数据，获得通过对所述第一曝光像素的内插值进行归一化的值和所述N×N个子像素阵列中的每个通道的所述第二曝光像素的内插值之间的差值; 将各个通道获得的差值中的不匹配值设定为最大值; 以及基于所述N×N个原始数据并基于所述不匹配值和阈值来设置所述N×N个子像素阵列中的中心像素的校正值。

Abstract: A multi-image sensor system includes data, clock, and control buses, an application processor connected to the data bus and the clock bus, and image sensors connected in a daisy chain using the control bus. A first one of the image sensors configured as a master outputs image data to the data bus, outputs a first clock signal to the clock bus, and sends a control signal to a second one of the image sensors in the daisy chain through the control bus. The control signal has a first logic state when output of the first image data starts and a second other logic state when output of the first image data ends. The second image sensor connects itself to the data bus and the master disconnects itself from the data bus according to a state of the first control signal.

Abstract: A time of flight (ToF) sensor includes: a first pixel including a first photogate to receive light reflected by an object and generate a first phase signal, and a second photogate to generate a second phase signal having a phase difference of 180 degrees with respect to the first phase signal; a second pixel including a third photogate to receive the reflected light and generate a third phase signal different from the first phase signal and a fourth photogate to generate a fourth phase signal having a phase difference of 180 degrees with respect to the third phase signal; a first signal output unit to output the first and second phase signals; and a second signal output unit to output the third and fourth phase signals, wherein the first, second, third and fourth photogates output the first to fourth phase signals during a frame period.
