Lecture 21: Image Sensors (53)

Is the over-presence of green filters just a product of circumstance and norms (no real difference between either color, just happened to pick green and maintain it as a standard? I researched this and the reason is because the human eye is more sensitive to green (due to equal activation of L and M cones) so having a more accurate reading of the green light from a particular sample produces seemingly higher quality images.

Something I was curious about was the need for these filters. Having the photoelectric effect being the main driver of the electrons being jettisoned off the metal and as a signal, wouldn't the factor of the number of electrons ejected being a function of the frequency directly inform the camera of the exact color frequency that's hitting the sensor? Is this possibly due to the rate of the electrons being ejected being too variable or difficult to record?
