Patent image
ARL

A method and system for forming an improved image from a series of frames comprising inputting a pixel value array for each image frame; summing the pixel values in each frame to obtain the frame intensity for each frame; multiplying the pixels in pixel value array by the frame intensity; summing the frame intensity multiplied pixel value arrays together and dividing by the number of frames to obtain an average of the frame intensity multiplied pixel value arrays; then, using the inputted pixel value arrays, creating an array of average pixel values; multiplying the array of average pixel values by the average frame intensity for all of the inputted frames; and subtracting the array of average pixel values multiplied by average frame intensity from the average of the frame intensity multiplied pixel value arrays to provide an array of modified pixel values to form an improved image.
