1. An imaging system, comprising:
a camera configured to capture images of an environment, the camera including a computational pixel imager (CPI) having a plurality of pixels, each of the pixels including:
a first counter configured to count up and down at a frequency F1 of a first modulated light source in the environment, such that a periodicity of an up-down count pattern of the first counter is synchronized with the frequency F1,
a second counter configured to count up and down at a frequency F2 of a second modulated light source in the environment, such that a periodicity of an up-down count pattern of the second counter is synchronized with the frequency F2, and
a third counter configured to count up and down at a frequency F3 of a third modulated light source in the environment, such that a periodicity of an up-down count pattern of the third counter is synchronized with the frequency F3,
wherein the frequencies F1, F2, and F3 are different from each other.
