about compensate command #1

Closed yofizane closed 2 months ago

yofizane commented 4 months ago

hello,would u please tell me whats the meaning of “amount of dimming” and “black value for screen detection” in the compemsate command

yaqwsx commented 4 months ago

The amount of dimming is the range of brightness (0-255) that is used to compensate for the bright spots. E.g. if you specify the amount to be 42, the most bright spot in the display will have brightness of 213 instead of 255.

The black value is a threshold of the sensor reading to detect areas outside of the LCD.

thank u very much Jan Mrázek! I am wondering if the TSL2561 sensor window is partially outside the lcd screen,what will the “cutoff” parameter do in that situation， will the compensate still accurate?

yaqwsx commented 4 months ago

Given the size of the sensor vs. the size of brightness unevenness I think it is negligible. Nevertheless, there is still the option to crop the image manually.
