ABSTRACT:
The present invention provides an apparatus and method for producing series of high resolution color composite images. The digital camera has an optical assembly that directs visual images to a high resolution monochrome sensor and a lower resolution color sensor. These two sensors, which produce a succession of frames at the same rate, are encrypted with a frame number and time code and are stored in a frame buffer. The contents of the frame buffer can be transferred to a mass storage device, or a color rendering processor that produces a composite image from the monochrome frames and color frames. During the processing of the composite image, the monochrome grayscale value becomes the composite frame grayscale value, the color frame hue value becomes the composite frame hue value, and the color frame saturation value becomes the composite frame saturation value. Alternatively, the monochrome frame grayscale value can be used to affect the composite frame hue and saturation values, or the composite frame hue and saturation values can be mapped from the color frame hue and saturation pixel linearly or non-linearly.
