• Frequently asked questions and answers about the AR0230 image sensor are as follows:

• 1. What are the basic specifications of the AR0230 image sensor?

• A: The AR0230 is a 1/2.7-inch CMOS digital image sensor with an effective pixel array of 1928(H) x 1088(V). It supports linear or high dynamic range (HDR) modes with rolling shutter readout. The sensor is suitable for low-light and high dynamic range scenes and can be programmed via a simple two-wire serial interface. (Information source: References 3, 6, 7)

• 2. What is the operating temperature range of the AR0230?

• A: The operating temperature range of the AR0230 is between -30℃ and 85℃. It should be noted that when used in high temperature environments, ensure that the device has sufficient heat dissipation measures to avoid affecting the performance and life of the sensor due to excessive temperature. (Information source: Reference 2)

• 3. How to solve the problem of AR0230 image redding in low-light environment?

• Answer: In low-light environment, AR0230 image sensor may have image redding problem. This is usually caused by increased gain and dark current. Ways to solve this problem include:

• Adjust the gain and dark current settings, but this may have limited effect. (Information source: Reference article 1)

• Try to use different image processing algorithms or filters to optimize image quality.

• Check and optimize the sensor's exposure time and white balance settings.

• If the problem persists, you may need to consider replacing a higher-performance image sensor or optimizing the entire imaging system.

• 4. What is the frame rate of AR0230?

• Answer: The maximum frame rate that the AR0230 image sensor can achieve is 60FPS (frames per second). The specific value of the frame rate may be affected by the sensor's operating mode, exposure time, and other factors. (Information source: Reference articles 2, 4)

• 5. What gain modes does AR0230 support?

• Answer: AR0230 supports two gain modes: LCG (low conversion gain) and HCG (high conversion gain). LCG mode is suitable for high-brightness environments, while HCG mode is used in low-light environments. The switching of these two modes is based on the size of the analog gain. When the analog gain is greater than or equal to 2.7X, the HCG mode needs to be used. In addition, in HDR mode, it is also necessary to set AdaCD (adaptive color noise filter) according to the gain to suppress color noise. (Information source: Reference articles 2, 4)

• 6. What is the package form of AR0230?

• Answer: The package form of AR0230 is iBGA 80Pin, and the package size is 10mm x 10mm. The pads are circular with a diameter of 0.5mm, a total of 80, arranged in a 9×9 manner, without A1 pads, and the center distance of the pads is 1mm. (Information source: Reference article 5)

• 7. What application scenarios are AR0230 suitable for?

• Answer: The AR0230 image sensor is suitable for a variety of application scenarios due to its high definition, low light and high dynamic range performance, including but not limited to monitoring, high-definition video recording, industrial cameras, medical imaging, etc. It can capture continuous video and single-frame images at the same time to meet a variety of imaging needs.
