  • Patent number: 10074319
    Abstract: A bi-stable electronic display driving technique drives an image refresh on a bi-stable electronic display, such as an electrophoretic display, using a driving integrated circuit with a single and limited in size image buffer, in a manner that does not require a simultaneous blanking or erasing of the display and in a manner that operates to drive the pixel elements of the display to their final value associated with the new image more quickly during an image refresh cycle. This technique results in an image refresh that is of higher quality and that is more pleasing to the eye while still using a driving integrated circuit with limited memory and processing power.

    Abstract: The invention relates generally to edge detection and presentation in thermal images. Infrared and visible light images comprising at least partially overlapping target scenes are analyzed. An edge detection process is performed on the visible light image to determine which pixels represent edges in the target scene. A display image is generated in which some pixels include infrared image data and in which pixels corresponding to edges in the visible light image include a predetermined color and do not include corresponding infrared image data to emphasize edges. Edge pixels in the display image can include exclusively the predetermined color, or in some examples, a blend of a predetermined color and visible light image data. Methods can include replacing one or the other of visible light edge pixels or corresponding infrared pixels with the predetermined color before combining the visible light and infrared image data to create a display image.
