A method for generating an high-dynamic-range (HDR) color image from a dual-exposure-time single-shot HDR color image sensor includes obtaining pixel values generated by a local region of sensor pixels of the image sensor, determining a motion parameter for the local region from pixel values associated with a first color, and demosaicing the pixel values of the local region to determine, for each of three colors, an output value of the images pixel, wherein relative contributions of short-exposure-time pixels and long-exposure-time pixels to the output value are weighted according to the motion parameter. A method for generating an HDR color image from a triple-exposure-time single-shot HDR color image sensor includes generating a first dual-exposure-time HDR image from short-exposure-time and medium-exposure-time pixel values, generating a second dual-exposure-time HDR image from medium-exposure-time and long-exposure-time pixel values, and generating a triple-exposure-time HDR color image from the first and second dual-exposure-time HDR images.
