Abstract: An input gray-scale image is converted to a bilevel output signal by an image-processing apparatus with two binarizing circuits: one employing a uniform threshold and the other a dither matrix. The outputs of these circuits are selected for each pixel by deciding whether the pixel is a bilevel pixel or a gray-scale pixel. The decision is based on the maximum and minimum gray levels in a block of pixels centered on the pixel in question. Images having both bilevel and gray-scale parts can thus be binarized with clean reproduction of black-white edges.

IPC: G02B7/36
Filed: 1991-07-23
Abstract: There is provided an automatic focusing device of a camera which accurately adjusts focus in a short time on the basis of recent and past information created in accordance with a focused object. The position of the object is predicted on the basis of the recent information and past information calculated at predetermined time intervals. It is therefore possible to accurately predict the position of the object in a short calculation time and to reliably determine whether the object is at rest or in motion. During a servo operation, a tracking servo operation does not begin erroneously for an object at rest. Once the tracking servo operation begins, because of hysteresis for determining whether the object is moving, the lens continuously and stably tracks the object. During the tracking servo operation, there is no delay of the time intervals at which the distance between the lens and the object is measured, and a distance moved by the object can be corrected and automatically adjusted. The lens can thus be moved smoothly in response to the movement of the object.

Abstract: An electronic reprographic printing system for printing on output sheets of a print job, wherein a set of electronic page images is created, such as by scanning a set of original documents, storing the electronic page images in memory, and wherein certain images are variably shifted on the output sheets. The amount of image shift (x-y) is dependent upon the size dimensions (y) of the original documents and the size dimensions (x) of the output sheets. This size dependent shifting allows for printing onto output sheets of varying sizes, or scanning from original documents of different sizes, such as from different scanning modes. The variable image shift is particularly useful for printing on tabbed sheets where the original documents are all of a standard size, and the images are specially shifted onto the tabbed sheets during printing.
