​IMX462 6.46mm diagonal (1/2.8 type) CMOS active pixel type solid-state camera image sensor

IMX462 is a 6.46mm diagonal (1/2.8 type) CMOS active pixel type solid-state image sensor with a square pixel array and 2.13 million effective pixels. The chip uses a triple power supply of analog 2.9V, digital 1.2V, and interface 1.8V, with low power consumption. It uses R, G, and B primary color mosaic filters to achieve high sensitivity, low dark current, and no smear. The chip has an electronic shutter with variable charge integration time.

Common questions and answers about IMX462 image sensor are as follows:

1. What are the basic specifications of IMX462 image sensor?

A: The IMX462 is a 6.46mm (1/2.8-inch) diagonal CMOS active-pixel solid-state image sensor with a square pixel array and 2.13 million effective pixels. It is powered by a triple power supply of analog 2.9V, digital 1.2V, and interface 1.8V, with low power consumption. This sensor is commonly used in applications such as surveillance cameras, FA cameras, and industrial cameras.

2. What is the pixel size and recommended number of recorded pixels of the IMX462?

A: The pixel size of the IMX462 is 2.9μm x 2.9μm. Its recommended number of recorded pixels is 1920(H) x 1080(V), about 2.07 million pixels. This means that in most cases, images close to or reaching this resolution can be captured using this sensor.

3. What is the maximum frame rate of the IMX462?

A: In full HD 1080p mode, the maximum frame rate of the IMX462 is 120 frames/second. This ensures clear capture and smooth video playback in high-speed dynamic scenes.

4. What high dynamic range (HDR) features does IMX462 support?

Answer: IMX462 supports multi-exposure HDR and digital overlap HDR features. These features help capture more details in environments with complex lighting conditions, reduce overexposure and underexposure, and improve the dynamic range of the image.

5. How to solve the image layering phenomenon when debugging the IMX462 image sensor?

Answer: When debugging the IMX462 image sensor, if you encounter image layering, it may be caused by the BypassMeshShading option not being enabled. Through the PQ debugging tool, checking the BypassMeshShading option usually solves this problem. This shows that BypassMeshShading is essential to eliminate image anomalies.

6. What is the package form of IMX462?

Answer: IMX462 uses a 110 pin LGA package form, which helps protect the internal circuit of the sensor and provides good electrical connection and heat dissipation performance.

7. What image processing functions does IMX462 have?

A: IMX462 has a variety of image processing functions, including CDS/PGA function (for adjusting analog gain and digital gain), 10-bit/12-bit A/D converter, adjustable settings for parameters such as brightness, contrast, sharpness, saturation, and advanced image processing functions such as backlight compensation, DOL mode wide dynamic, 2D/3D noise reduction. These functions work together to improve image quality and visual experience.

8. What interfaces and data formats are applicable to IMX462?

A: IMX462 supports MIPI-CSI2 interface and can output uncompressed UYVY data format and YUV422-8bit data type. These interfaces and data formats help to achieve high-speed, high-quality image data transmission and processing.
