Get or Set the Video Sharpness Level.
This URL is only available for some sensors and ISP platforms.
In MT9M131 and MT9V135 sensor, there are 7 sharpen levels (1~7).
In ISP C3 platform, there are 4 sharpen levels (1~4). And set sharpen level to 0 will disable the sharpen function.
The error message will be returned if the encoder does not support this URL.
n: 1~255
where the value in n was mapped into different sharpen levels.
The following table gives the mapping rule of value n with platforms (sensor and ISP).
Sensor ISP Platform mapping rule in n MT9V135, MT9M131 None Sharpen Level to sensor = (n > 32) ? n/32 : 1 None C3 ISP Sharpen Level to ISP = n / 52
That means the sharpen function is disabled when n is from 1~51.
