Abstract
Pixel density limits the resolvable detail and edge-location precision of any camera. The new cameras address this problem by increasing the number of pixels, or in the case of the Kontron Progress 3000 invented by Reimer Lenz small pixels are moved behind the lens to 'fill in' the image area. This paper discusses a similar approach to the Lenz approach except that the entire camera is moved. An image is taken and then the camera is moved to a new location, from a fraction of a pixel to a full pixel from its first location, and a second image is taken. This is repeated until sufficient data or repetition of data is obtained. The task now becomes to reassemble the image in the correct location to get an image of enhanced precision. Moving the camera gives rise to a number of problems which must then be dealt with.
