AR0234 1/2.6-inch, 2.3MP CMOS Camera Digital Image Sensor

The AR0234 is a 1/2.6-inch, 2.3MP CMOS camera digital image sensor with an innovative global shutter pixel design that accurately captures moving scenes at 120 frames per second at full resolution.

The sensor has an effective pixel array of 1,920 pixels by 1,200 pixels, producing clear, low-noise images in both low-light and bright scenes.

The AR0234 CMOS image sensor's MIPI interface has a high data rate. This makes it ideal for vision systems implementing artificial intelligence (AI) technology. The AR0234CS has a high frame rate and low power consumption at full frame rate and full resolution, allowing vision system developers to allocate most of the timing and power budget to the host processor instead of the image sensor.

The XGS series of CMOS image sensors for high-resolution industrial imaging complements the AR0234 in the ON Semiconductor portfolio. XGS components are high-performance, low-noise image sensors that deliver excellent image quality and support resolutions from 2 megapixels to 45 megapixels.

All XGS devices feature 3.2µm pixels, producing low noise and high image quality, which is critical for IoT applications such as machine vision and intelligent transportation systems. To simplify and speed time to market, XGS devices are based on a common architecture that enables you to implement the same camera design with a variety of products with higher or lower resolutions.

What are some common questions about the AR0234 camera image sensor?

What are the basic specifications of the AR0234 camera image sensor?

Answer: The AR0234 camera image sensor is a 1/2.6-inch 2Mp (or 2.3Mp in some versions) CMOS digital image sensor with an active pixel array of 1920 (H) x 1200 (V). It uses a global shutter pixel design to accurately and quickly capture moving scenes at full resolution of 120 frames per second, suitable for clear, low-noise image capture in low-light and bright scenes.

How does the AR0234 camera image sensor perform in low-light environments?

Answer: The AR0234 camera image sensor performs well in low-light environments, thanks to its optimized pixel design and low-noise characteristics, which can produce clear, low-noise images in low-light conditions. This makes it an ideal choice for applications such as barcode scanners and gesture recognition that require high sensitivity and low noise characteristics.

What common problems may occur when using the AR0234 camera image sensor?

Answer: The AR0234 camera image sensor may encounter a variety of problems during use, including but not limited to:

Excessive image noise: This may be caused by excessive sensor operating temperature or improper exposure time setting. Solutions include optimizing heat dissipation design, adjusting exposure parameters, etc.

Image color distortion: Color distortion may be caused by incorrect white balance setting, inaccurate lens shading correction, or sensor internal circuit failure. It can be solved by adjusting white balance, calibrating lens shading, or replacing the sensor.

Image blur or ghosting: This is usually related to global shutter or frame synchronization problems. Checking whether the global shutter setting is correct and whether the frame synchronization signal is stable can help solve this problem.

Data transmission error: When transmitting data using MIPI or parallel interface, data transmission errors or frame loss may occur. This may be caused by improper interface configuration, signal interference, or cable quality problems. Ensuring that the interface configuration is correct, the signal is stable, and the cable quality is reliable can effectively avoid such problems.

How to detect whether the AR0234 camera image sensor is faulty?

Answer: To detect whether the AR0234 camera image sensor is faulty, you can follow the following steps:

Observe the image quality: First observe the image quality of the sensor output to check whether there are noise, color distortion, blur or ghosting.

Check the interface signal: Use an oscilloscope or other tools to check the signal waveform of the MIPI or parallel interface to ensure that the signal is stable and meets the specification requirements.

Test the sensor function: According to the instructions in the data sheet, test the various functions of the sensor, such as automatic exposure control, window mode, row/column skip mode, etc., to ensure normal function.

Temperature test: Test the working stability of the sensor in a high temperature environment to check whether there is performance degradation or failure due to excessive temperature.
