A photosensitive material which when imagewise exposed to record a latent image thereon is formed with an image by heating with a prescribed processing material superimposed thereon is used as a photographic film or the like, the photosensitive material is exposed to record an image thereon, the exposed photosensitive material is developed by superimposing and heating the photosensitive material and the processing material to form the image on the photosensitive material and then peeling the photosensitive material formed with the image off the processing material, the developed image on the photosensitive material is read with a scanner to obtain image data representing the image, and the image data are subjected to prescribed image processing to generate reproducible digital image data.

Image forming method and system

An automatic light measuring device for an image pickup device includes a pair of line sensors suitable for an automatic focusing adjustment and disposed on a semiconductor chip at positions spaced apart by a predetermined distances, an integration time controller for generating an integration control signal for controlling the charge accumulation by incident light by detecting the amount of charges accumulated in the line sensors, a first exposure amount detector for calculating the intensity of incident light from the integration control signal, a second exposure amount detector inclusive of photoelectric conversion elements formed on the semiconductor chip, for detecting the amount of incident light, a pair of lenses mounted above the pair of line sensors for focusing the image of substantially the same subject within the central area of the field of view, and an optical system for applying light within the area broader than the central area of the field of view to the surface of the semiconductor chip inclusive of the photoelectric conversion elements. The photoelectric conversion elements are disposed between the pair of line sensors. The optical system may be made of an acrylic rod, light focusing fibers, retrofocus lens, or the like.

Automatic light measuring device for image pickup device

A range finding device having a lens holder with two tunnels, and two lens plates mounted in front of the tunnels. Two pins are formed on the front surface of the lens holder, the two pins being positioned on vertical positioning lines externally of the vertical center lines of the two tunnels. Each lens plate has an elongated hole extending in the direction of the vertical positioning line, a pin being inserted in the elongated hole. In a preferred embodiment, each lens plate has four holes formed therein. Two of the four holes are used for coupling with two pins. Of these two holes used for positioning, one is a round hole and the other is an elongated hole.

Range finding device unaffected by environmental conditions

An image forming method for use with a photosensitive and pressure-sensitive material fed from a supply position to an exposure position by entrance-side and exit-side nip rollers disposed on opposite side of the exposure position in contact with an exposed material supporting roller. To eliminate sag from the sensitive material, the entrance-side and exit-side rollers are operated with a differential timing. To reduce the per sheet exposure time, a fresh segment of the photosensitive and pressure-sensitive material is fed to the exposure position immediately following each exposure operation.

Image forming method

An image recording apparatus which makes use of a photosensitive and pressure-sensitive thermally developable medium having a carrier and a photosensitive substance applied to the surface of said carrier that is capable of developing a latent image thereon by application of heat and stabilizing the developed image by application of pressure, said apparatus comprising: exposure means; heating developing means; and transferring means for superposing an image receiving sheet member onto said photosensitive and pressure-sensitive developable medium and for pressurizing said image receiving sheet member and said photosensitive and pressure-sensitive developable medium together.

Image recording apparatus

An image recording apparatus employs a photo- and pressure-sensitive heat-developable material having a substrate and a layer formed on the substrate from a material which is photo-sensitive and heat-developable and which enables the developed image to be fixed by a pressure. The apparatus has the following major parts: an exposure device for exposing the material to an original image so as to form a latent image corresponding to the original image on the photo-sensitive material; a heat-developing device for thermally setting the portion of the material corresponding to the latent image thereby immobilizing the image; a pressing transfer device for superposing the material and an image-receiving material in contact with each other and pressing them together; and a conveyor drum defining a path of convey therearound. At least two of the exposure device, the heat-developing device and the pressing transfer device being arranged along the path.
