Hello Friends,

I have Sabrelite BD-SL-i.MX6 board from boundary devices.

I have ov5640 camera (Image Sensor).

Now I want to know the luminance value from the sensor in my application.

What is the way to go ahead on this.? How should i get luminance value.

Please  suggest me a way to this.

Hi Hitesh!

You can easily get luminance by transform RGB to Brightness by this formula:

Y = 0.3R + 0.59G + 0.11B

You will get a 255 gradations of brightness.

Best Regards,

Ivan.
