Abstract
A fast light interconnected processor device for image processing includes an image sensor for producing a line scan signal, a one-dimensional line display for producing a light having an intensity representative of the scan signal and an array of light detectors for producing a two-dimensional convolution of the image with a blurring function performed simultaneously with the scanning of the image scene. The image sensor is, for example, a thermal imager (forward looking infrared system) which outputs electrical signals representative of thermal energy emanating from a scene. The one-dimensional line display is, for example, a one-dimensional array of light emitting diodes which converts the electrical signals of the thermal image to a light image. And the array of light detectors is, for example, an array of charge transfer devices positioned to receive the light image and produce the two-dimensional convolution of the image with a blurring function performed simultaneously with the scanning of the image scene for a contrast map. A zero crossing detector may be connected to the light detector array for producing an outline of the image. Also, the one-dimensional line display may …
