Claim One:
1. An imaging system, comprising: an image sensor to capture a sequence of images including at least one low dynamic range (LDR) image and at least one high dynamic range (HDR) image; control circuitry and readout circuitry, wherein the control circuitry is coupled to the image sensor to control LDR image capture and HDR image capture, and wherein the readout circuitry is coupled to read out image data captured by the image sensor; a processor coupled to the readout circuitry to receive image data corresponding to the at least one LDR image and image data corresponding to the at least one HDR image, and wherein the processor is configured to: generate a mix mask; combine high frequency image data extracted from image data corresponding to the at least one LDR image with low frequency image data extracted from image data corresponding to the at least one HDR image; and generate a composite image from the low frequency image data and the high frequency image data, wherein the mix mask governs placement of the high frequency image data and the low frequency image data in the composite image; and a data output coupled to the processor to receive the composite image.
