How to get more resolution from the onsemi 18 MP color sensor

The 18 Megapixel sensor AR1820HS in our UI-3590 camera models has been released by onsemi as a pure color sensor.

As with all color sensors, the Bayer filter therefore effectively provides you with color images "only" with about a quarter of the nominal sensor resolution, since the color information of one pixel is obtained from four neighbors. However, it is not enough to operate the sensor in data RAW format (without Bayer interpolation) to use each individual pixel. The Bayer matrix provides a different perception of the brightness of the individual pixels.

Operating a color sensor as a mono sensor

We will show you how to use the color sensor as a "pure" mono sensor to obtain a significantly higher resolution: by using appropriate parameterisation and suitable light sources.
