This invention is relative to an image information display apparatus in which a large-sized image can readily be recognized even with use of a small-sized display unit such as is provided in a portable telephone set or in a mobile computer. It is assumed that an observer (user)is about to recognize an image of a larger sizeusing an image information display apparatushaving a displayof a smaller size. When the observermoves his or her hand, a partial areaof an image demonstrated in the displayis actively changed. This permits the image of a larger sizeto be comprehended readily in its entirety. The image of a larger sizecan readily be recognized by having the hand movement matched to the movement of the display image (partial areaof the image), based on perceptual characteristics of the human being.

Image information displaying apparatus

An object surface is imaged by an imaging unit () and, based on the imaging information by the imaging unit (), the information corresponding to the object is read out and recognized to identify the object, as an object identification code indicating the information set corresponding to the object stored in the storage unit () and the information for specifying the information in the information set corresponding to the object are matched to a position on the object surface by an imaging unit () and a controller (). In this manner, the knowledge stored in the information system can be freely accessed without producing break points, if the knowledge is to be used.

In order to reduce errors in sensing an image position derived from noise light such as background noise, a semiconductor image position sensing device is provided with a photoelectric layer generating a photoelectric current in a portion onto which light was input in response to intensity of the light input to the photoelectric layer, a resistance layer laminated on the photoelectric layer in which the photoelectric current generated in the photoelectric layer flows into a portion corresponding to that onto which the light was input, and signal current output terminals wherein the photoelectric current generated in the photoelectric layer is distributed in a ratio in response to a resistance value between the signal current output terminals and the resistance layer defined at a position where the photoelectric current flowed into the resistance layer and from which the photoelectric current is output as an electric current obtained by summing currents over the whole sensing sections altogether, comprising further a resistance subtracting a photoelectric current having a predetermined distribution of electric current density from photoelectric currents generated in respective portions of the photoelectric layer over the whole sensing sections, and the photoelectric current subtracted by means of the resistance being adapted to flow into the resistance layer.

A semiconductor dark image position sensing device comprises a photoelectric layer generating a photoelectric current in a portion where light is input in response to intensity of the light input, a resistive element layer into which the photoelectric current generated in the photoelectric layer flows from a portion corresponding to the position of light input, a second resistive element disposed in association with the photoelectric layer for replenishing an insufficient amount of electric current with respect to the photoelectric current so as to flow the same into the resistive element layer in such that a distribution of electric current flowing into the resistive element layer corresponding to the position of light input becomes substantially uniform over a whole sensing region, and signal electric current output terminals disposed at the opposite ends of the second resistive element.

An apparatus for the formation of a visual sense effect comprises a first object A having a plurality of windows disposed around an axis of rotation C and a second object B so disposed as to show part thereof through the windows W of the first object A, with the first object A and the second object B adapted to be rotated relative to each other round the axis of rotation C. By virtue of the visual sense effect in vision, this apparatus allows an object of a polygonal shape to be perceived as though the object were repeating enlargement, contraction, deformation, and eccentric movement.

In an image position sensitive device having a photo conductive layer, resistive layer and a group of the output electrodes for separating the resistive layer into a plurality of sections, the group of the output electrodes is divided into a plurality of sets and a common output terminal is provided for each set of the electrodes in order to collectively detect output currents from the electrodes of each set. The number of output terminal is extremely reduced to simplify conformation of a circuit for determining a detection region.

Disclosed is a method of monitoring the state of focusing of an image on a semiconductor image position sensitive device of the type having a photosensitive layer, a resistance layer provided on the photosensitive layer and output terminals provided on the resistance layer. In this method, a bright spot image is moved across a border between a light-insensitive or non-sensitive zone and a light-sensitive zone. The rate of change in the level of an output signal obtained when the bright spot image is moved across the border is then detected. The degree of focusing of the bright spot image is then derived from the state of change in the level of the output signal.

Disclosed in an optical distance measuring apparatus using an observation lens and at least one reflector. Thanks to the use of reflectors the whole size of the apparatus reduced at least one half of a conventional distance measuring apparatus, still assuring the same exactness as the conventional apparatus in measuring a distance.

Disclosed is an apparatus for determining the position of a mark on an object to be determined in terms of configuration, movement or any other geometrical or physical condition, using a photosensitive element and a light reflecting body in such a combination that the reflecter intercepts and casts to the photo-sensitive area of the element the beam of light from the mark, which beam of light would, otherwise, travel apart from the photo-sensitive element, not falling thereon. Thus, the measuring range of the photo-sensitive element is apparently extended, or otherwise the accuracy with which the mark position is determined is substantially improved.

Disclosed is an improvement of method and apparatus for varying the cross-section of a beam of electrically charged particles and projecting the so-varied beam onto the target. Passing through a plurality of apertured masks one after another, a beam of electrically charged particles is so deflected that the image of the overlapping area of the apertures of the masks appears on a target. According to this invention a beam of charged particles is deflected between two subsequent masks upstream so as to reduce the amount of beam current to that which is required in forming a desired image on the target, and the so-reduced beam is deflected between two subsequent masks downstream so as to trim and shape the cross-section of the beam into the exact and sharp contour as desired. The method and apparatus for varying and projecting a beam of electrically charged particles according to this invention are particularly useful in producing microcircuits.
