Abstract:
1. A method for enhanced color imaging in a low light environment, the method comprising: illuminating a red (R), a green (G), and a blue (B) light at different time periods; capturing an R image frame, a G image frame and a B image frame, in response to the illumination; generating an intermediate color frame for each of the R, G and B image frames; determining moving pixels in each intermediate color frame; determining a true color for the moving pixels in said each intermediate color frame; generating a true color frame for said each intermediate color frame by substituting colors of the moving pixels with respective true colors of the moving pixels, in said each intermediate color frame; calculating scene color metrics of the true color frame for said each intermediate color frame; and adaptively adjusting illumination of one or more of the R, G, and B lights to enhance a next true color frame.
