Abstract:
An interface circuit to control an acquisition of a number of pixels in a scanning system, the interface circuit comprising:a multiplexer to route at least one color component of one of a number of pixels to a register, the multiplexer having at least three color component inputs to receive at least three color components for each of the pixels; logic to control a selection signal applied to the multiplexer and a sample signal applied to the register to acquire the at least one color component according to a color acquisition sequence, the color acquisition sequence causing an acquisition of a number of color components associated with an image that is less than a total number of color components of the image; and logic to generate a number of calculated pixels from the acquired ones of the color components, the calculated pixels having a resolution that is less than a resolution of the image, each of the calculated pixels including a number of averaged color components.
