A color imaging device comprising: one or more arrays (10, RA, GA, BA) of color-selective photodetectors (R, G, B) configured to acquire a color image of a subject; digital image processing circuitry configured to select the color image and/or a luminance image to generate an output image of the subject, wherein the digital image processing circuitry is configured to quantify an image intensity metric based on the color image, and to compare the image intensity metric with an intensity night vision level threshold and to select the output image as the luminance image of the subject if the image intensity metric is below the intensity night vision level threshold, characterized by a set of avalanche photodiode photodetectors arranged to acquire the luminance image of the subject; wherein the digital image processing circuitry is further configured to compare the image intensity metric with an intensity daylight level threshold and to select the output image as the color image of the subject if the image intensity metric is above the intensity night vision level threshold and above the intensity daylight level threshold, to generate a modified color image by adjusting the color image based on corresponding content of the luminance image and to select the output image as the modified color image of the subject if the image intensity metric is above the intensity night vision level threshold and below the intensity daylight level threshold. one or more arrays (10, RA, GA, BA) of color-selective photodetectors (R, G, B) configured to acquire a color image of a subject; digital image processing circuitry configured to select the color image and/or a luminance image to generate an output image of the subject, wherein the digital image processing circuitry is configured to quantify an image intensity metric based on the color image, and to compare the image intensity metric with an intensity night vision level threshold and to select the output image as the luminance image of the subject if the image intensity metric is below the intensity night vision level threshold, characterized by to quantify an image intensity metric based on the color image, and to compare the image intensity metric with an intensity night vision level threshold and to select the output image as the luminance image of the subject if the image intensity metric is below the intensity night vision level threshold, characterized by a set of avalanche photodiode photodetectors arranged to acquire the luminance image of the subject; wherein the digital image processing circuitry is further configured to compare the image intensity metric with an intensity daylight level threshold and to select the output image as the color image of the subject if the image intensity metric is above the intensity night vision level threshold and above the intensity daylight level threshold, to generate a modified color image by adjusting the color image based on corresponding content of the luminance image and to select the output image as the modified color image of the subject if the image intensity metric is above the intensity night vision level threshold and below the intensity daylight level threshold.
