A liquid crystal display having a plurality of sets of matrix wiring elements, a plurality of active elements and a liquid crystal layer includes a conductive layer for being maintained at a predetermined potential, which layer is selectively provided around each of pixel electrodes individually provided for each pixel. An image information processing apparatus includes such a liquid crystal display. The selective formation of the conductive layer makes it possible to reduce cross-talk while reducing the risk of the generation of unwanted parasitic capacitance and leakage current.

An image display apparatus, having a pixel configuration in which pixels on the n-th line and pixels on the n+1-th line are deviated in the horizontal direction, improves the resolution in the horizontal direction by changing over an image signal to be sampled between a delay signal DL and a through signal TH supplied from a delay circuit so as to deviate the image signal by a time corresponding to the deviation of the pixels. By sampling the image signal which corresponds to each line while deviating the image signal by the time which corresponds to the deviation of the pixels in the horizontal direction, the deviation between the pixel and the signal is eliminated, so that the resolution in the horizontal direction is improved.

Image data is hierarchically coded by a coder, and the coded data is stored in a database. A decoder hierarchically decodes the coded data stored in the database, and image data corresponding to each hierarchy is generated. The decoder generates image data of a plurality of levels of resolutions from a low resolution to high resolution from the coded data stored in the database. The image data of the high resolution is original image data. Editing such as enlargement, reduction, transfer, and rotation, specified by an operator, is executed using the image data of the low resolution obtained from the decoder. The content of the edit processing by the operator is stored in a memory. When the editing operation ends, CPU executes the edit processing on the original image data obtained from the decoder based on the content of the edit processing stored in the memory. The final editing is thus performed on the original image data.

Inexpensive, maintenance-free and high efficiency reluctance motors and generators have a construction that makes it possible to decrease pulsating torque and additional harmonic core loses. Each salient pole of the rotor core of the reluctance motor and generator has a shape such that the gap permeance varies in proportion to cos (N.theta..sub.2), where .theta..sub.2 represents an angular position with respect to the origin set to the center of a salient pole, or a shape analogous to the shape. In order to make up for a reduction of reluctance torque due to the shape, slits are provided inside the rotor core which cause a large reluctance for the quadrature-axis flux without interfering with the direct-axis flux.

A focus detection system for detecting a focus state of an object lens, includes an optical device for forming first and second light distributions corresponding to first and second images having light fluxes passing through the different parts of a pupila of the object lens. The positional relationship between the two light distributions varies in accordance with the focus state of the object lens. First and second sensors sense the first and second light distributions. A signal processor for processing output signals from the first and second sensors detect the focus state of the object lens in accordance with the positional relationships between the two light distributions. The signal processor processes the signals from the first and second sensors in accordance with a predetermined formula to obtain the positional relationship between the two images to determine a degree of coincidence of the two light distributions. The signal processing means provides an output signal in accordance with the degree of coincidence of the two light distributions.

The invention relates to an automatic focusing apparatus, particularly, of a type wherein a lens drive amount is calculated by circuits in a camera in accordance with an output from a focusing detection circuit, the calculation result is transmitted to a lens mounted on the camera, and the lens is driven accordingly. While the lens unit is driven for a distance corresponding to the calculation result, operation of the focusing detection circuit of the camera is prohibited by sending a signal for prohibiting the operation of the focusing detection circuit thereto through a contact for transferring data from the camera to the lens unit in modes other than the lens drive mode. The number of contacts between the camera and the lens unit is reduced.
