Abstract

A high resolution, high speed digital camera that produces a high resolution image representative of an image scene viewed by the camera. The digital camera comprises an input lens system and an iris that couple light from the image scene into the camera. A first imager generates a sequence of high resolution, low speed digital frames of the image scene. A second imager generates a sequence of low resolution, high speed digital frames of the image scene. Image processing electronics process the digital outputs of the respective imagers to register the high speed and low speed digital frames to each other, generate a vector field that describes the motion of pixels from one frame to the next in the sequence of low resolution, high speed frames, and interpolate pixels of the next frame in the sequence of high resolution, low speed frames using the vector field to translate them in the same manner as the pixels changes in the low resolution, high speed frames to produce high resolution digital frames representative of the images in a scene containing objects moving at high speed.
