ABSTRACT:
A color sequential electronic camera includes an RGB light source in which the R and G sources are activated in combination to provide a luminance light beam, and the R and B sources separately to provide separate chrominance light beams. Image light reflected by a subject is captured by an image sensor, which generates a color sequential signal comprising a sequence of luminance and chrominance image components. By activating the light sources such that chrominance light beams alternate between luminance light beams, the chrominance image components are captured at a lower temporal rate than the luminance image components. Furthermore, by binning the sensor photosites together for the chrominance image, the chrominance components are captured at a lower spatial resolution than the luminance image components.
