Sensor de imagem de câmera CMOS com obturador global SC130GS

SC130GS is a global shutter CMOS image sensor that supports a maximum transmission rate of 1280Hx1024V@240fps. SC130GS outputs black and white RAW/RGB images with an effective pixel window of 1288Hx1032V, and supports complex on-chip operations – such as HDR mode, external trigger global exposure mode, windowing, horizontal mirroring, vertical inversion, etc. SC130GS can be configured through standard SPI and I2C interfaces.

SC130GS can achieve external control of exposure through the Trigger0 pin.

Function Introduction

1. External trigger global exposure mode

In external trigger global exposure mode, the main control chip triggers exposure through the Trigger0 signal to achieve synchronous exposure and video data output of multiple sensors. When the Trigger0 signal occurs, the SC130GS starts to expose, and outputs video data after the exposure. The frame rate is controlled externally. When the SC130GS works in external trigger global exposure mode, the main control chip triggers exposure through the Trigger0 pin.

According to the control method of exposure time, the external trigger global exposure mode is divided into external trigger global Master Mode and external trigger global Slave Mode.

2. AEC/AGC

AEC/AGC are both adjusted based on brightness. AEC adjusts the exposure time and AGC adjusts the gain value, so that the image brightness finally falls within the set brightness threshold range.

3. Black level control (BLC)

The SC130GS pixel array contains 8 black lines, which can provide data for the compensation elimination algorithm. Digital image processing first subtracts the black level data. The BLC algorithm estimates the black level compensation value from the black line data, and the color pixel value is subtracted from the black level compensation value of the respective color channel. If such subtraction results in a negative value at some specific pixel point, the result is set to 0.

By default, the BLC operation is re-performed after changing the gain value.

There are two black level calculation modes: manual BLC and automatic BLC. In manual mode, the compensation value is specified by the register; in automatic mode, the compensation value is calculated by the black line.
