Hello,
I'm using photo-sensors from commercial and industrial cameras to document an experiment. Afterwarde I evaluate the change in brightness during the test of a fixed segment of every image I took. The ambient light condition is stable and the images are in raw files, but I'm unsure how raw they are.
I read that in photometry, the radiant power of each wavelength is weighted by a luminosity function, because they want to mimic the sensitivity of the human eye to different wavelengths.
Does this happen here, too? I mean, I know that the sensors are reading absolute values, but are the absolute values weighted by a luminosity function in the camera afterwards? Or do the images contain the absolute values and our eye does the weightening?
In the end, I just want to know if the pixel of the images I reading out are in absolute or weighted values. I could not find anything so far on the web. I'm grateful for every help I'm getting!
regards
Jim
