The hardest part seems to graduate the sharpness levels, as sharpness actually is split into 3 different controls. Of course, one interested on doing that would need to have a device with the needed chipsets and time/interest on doing that. Adding control framework at stk1160 also requires some time. I can't volunteer myself of doing that. I don't have any stk1160-based devices. > Unfortunately, I'm not very good with system drivers programming. > > I'm interesting only in sharpness control because the image quality > (sharpness) during capture using CVBS input is bad (on my EasyCap > device). If I use S-Video input, the quality (sharpness) is better. Yeah, the saa7115 datasheet (freely available at NXP site) mentions that sharpness control may be needed for some kinds of output. > It is important to implement it, because the sharpness control > implemented in hardware (not in software, post-processing filtering). > Control of other parameters like gamma are also don't work, but I'm > not sure that gamma control is hardware (not software) implemented > (I'm not found any info about gamma in saa7113 datasheet).
