Colposcope video camera driver
For factory "Zenit", famous for its cameras, we have developed a software package for a colposcope video camera.
The complex incorporates:
- video camera drivers;
- technology software for driver setup;
Video module for which the driver was developed:
Driver is designed as a Directshow filter. It performs full processing of the image coming from the camera. Thus, the following steps are performed:
- elimination of hot and cold pixels;
- black level correction;
- white level correction;
- uniformity correction;
- white balance correction;
- color correction..
Technology software was used for adjusting parameters of all corrections.
This software is designed for viewing the intermediate image received from the camera, setting up the correction parameters, and recording them to the driver.
The whole chain of image processing from the camera is presented below. Please note that these pictures were taken in our office, not in a dedicated laboratory. Therefore, the image quality is not so high.
Initially, the image comes in black and white. First of all, parameters affecting the brightness and contrast are corrected:black level:
And white level:
Then the uniformity is corrected. This process is followed by conversion, giving colors to the image:CFA interpolation:
Then the white balance should be adjusted for a certain light source:
The final stage is color correction:
