Sony IMX377_camera chip image sensor

The imx377 CQT is a 7.81mm diagonal (1/2.3 type) CMOS image sensor with a color square pixel array and approximately 12.35M effective pixels. 12-bit digital output makes it possible to output S igals of approximately 12.35M effective pixels with high definition for shooting still images.

It also has three power supply voltages of analog 2.8V, digital 1.2V, and I/O interface 1.8V, achieving low power consumption.

In addition, it achieves 12-bit digital output by horizontal and vertical addition and subsampling for shooting high-speed and high-definition moving images. To achieve high sensitivity, low dark C current, the sensor also has an electronic shutter function with variable integration time.

In addition, this product is designed for consumer use digital cameras and consumer use camcorders. Sony cannot guarantee the quality and reliability of the product when this application is used for another application.

Therefore, do not use it for applications other than consumer use digital cameras and consumer use camcorders. In addition, individual specification changes cannot be supported because this is a standard product.

3. What are the common faults of IMX377 camera image sensors?

A: Common faults of IMX377 camera image sensors may include but are not limited to:

"Hot pixel" phenomenon: After working for a long time, the temperature of the sensor rises, which may cause some pixels to overheat and appear noise or bright spots.

Image color cast or stripes: Due to data line problems or signal interference, the image may appear color cast or striped noise.

Image afterimage (tailing phenomenon): Some charges are not completely transferred and remain in the photodiode, resulting in the afterimage of the previous frame in the next frame.

Insufficient full well capacity: affects the dynamic range and signal-to-noise ratio of the image sensor, and may cause loss of details in the highlight area.

4. How to solve the "hot pixel" phenomenon of the IMX377 image sensor?

Answer: The methods to solve the "hot pixel" phenomenon of the IMX377 image sensor include:

Optimize heat dissipation design: Ensure that the camera dissipates heat well during use to avoid long-term continuous operation causing excessive temperature.

Use noise reduction algorithms: Use noise reduction algorithms in the backend or software processing to reduce or eliminate the "hot pixel" phenomenon.

Regular maintenance: Regularly check and clean the sensor surface to ensure that there is no dust or impurities that affect the image quality.
