Application Fields and Working Principle of OV06946-ECJA-CH0A Image Sensor

The OV06946-ECJA-CH0A image sensor is widely used for its excellent image quality and resolution in vehicle vision systems. The primary applications include automotive cameras, rear view cameras, exterior cameras, mobile phone cameras, and consumer cameras The OV06946-ECJA-CH0A image sensor is also suitable for applications such as video cameras, medical imaging, and machine vision. The sensor is based on a CMOS technology that uses CCD components to capture light, process it, and then output an analog or digital signal. A lens focuses the light onto the photodiode array, which is then read out by the image sensor. The images are processed using an image signal processor (ISP) and then output to the display device. The OV06946-ECJA-CH0A image sensor’s AF operation is based on the VCM (voice coil motor) to adjust the’s image plane. The AF performance of the image sensor depends on the VCM’s closed loop system. It also supports the MTF (Modulation Transfer Function) cancellation to reduce blur and prevent chromatic aberration.

Conclusion

The OV06946-ECJA-CH0A image sensor is a versatile and high-performance image sensor that offers excellent image quality, resolution, and AF performance for automotive cameras, rear view cameras, exterior cameras, mobile phone cameras, consumer cameras, video cameras, medical imaging, and machine vision applications. Its key features include a 3-megapixel active pixel array, a 3.2 µm pixel size, and a 2.2-megapixel field-of-view at full resolution. Its AF operation is based on the VCM, and it supports the MTF cancellation to reduce blur and prevent chromatic aberration.
