Abstract: In a solid-state image pick-up device comprising a plurality of light receiving sensor sections, a vertical transfer path 12 formed close to each of the light receiving sensor sections, and a channel stopper 13 provided between the adjacent vertical transfer paths 12 and formed by an insulating layer having a trench structure, a conductive substance 15 to which a predetermined voltage is applied is buried in the insulating layer 14. The predetermined voltage is a negative voltage if a signal charge is an electron, and is a positive voltage if the signal charge is a hole. Alternatively, the predetermined voltage is a pulse having an opposite phase to that of a read pulse to be applied to a transfer electrode 17 of the vertical transfer path 12.

Abstract: In an image processing apparatus to conduct an on-screen display operation, the bus band of an image memory is minimized. The apparatus includes an image memory including a first memory area to store a first image data group of a first image for a background and a second memory area for storing a second image data group of a second image for an on-screen display, a display buffer memory for storing, in a format to be displayed on a display screen, the first image and the second image read from the image memory; and a control section for controlling accesses in the image memory and the display buffer memory, for reading the first image data group from the first memory area and writing the first image data group in the display buffer memory, and for reading the second image data group from the second memory area and writing the second image data group in a specified area of the display buffer memory.

Abstract: A stimulable phosphor film in which acicular particles of stimulable phosphor having an aspect ratio of 1.5 or more are oriented in the direction of depth of the phosphor film gives a reproduced radiation image having increased sharpness when it is employed in a radiation image recording and reproducing method.

Abstract: A method for preparing a photographic photosensitive film comprising a support and formed on at least one side thereof photographic constituent layers containing a photosensitive silver halide emulsion layer is disclosed, which comprises subjecting the photographic photosensitive film to an "out-of-roll curling treatment" so as to result in an outermost-lap curl value of from 55 m.sup.-1 to 200 m.sup.-1 as measured after the treated film is housed in a cartridge, with the emulsion layer side facing inward. Also disclosed are a photographic photosensitive film which comprises a support and formed on at least one side thereof photographic constituent layers containing a photosensitive silver halide emulsion layer and has been prepared by the above method, and a photographic film cartridge containing housed therein the above photographic photosensitive film so that a front end part of the film is out of the cartridge over a length of at least 1 cm.

Abstract: In a photographic camera, a film cartridge having a roll film rolled around a spool in a cartridge body and a shutter member for opening and shutting a film exit slit is loaded in a cartridge chamber. A chamber lid is mounted on the camera to be swung between an opening position where it opens the entrance opening to the cartridge chamber and a closed position where it shuts the same. A spool pressing member provided on the inner side of the chamber lid pushes an end of the spool of the film cartridge at a predetermined pressure when the chamber lid is closed. An arm member is mounted on the inner side of the chamber lid at one end to be swung about the end away from and toward the chamber lid and urged away from the chamber lid by a spring at a pressure larger than the predetermined pressure.

Abstract: A printer processor, a film processor, and a densitometer are connected to a personal computer via a port controller. To diagnose the operational condition of photographic apparatus, the apparatus forms a check sample. The check sample is sent to the densitometer to fetch the measured density data into the personal computer. If the operational condition of the photographic apparatus is abnormal, the personal computer fetches the operational data under management in the photographic apparatus to determine a countermeasure for the abnormal state. The countermeasure is transferred to the photographic apparatus to adjust the adjust failure element automatically. In order to control a plurality of lab shops remotely, each lab shop is provided with a sub-computer connected to the photographic apparatus. The headquarters are provided with a main computer storing therein a management program. The main computer fetches the data of the sub-computer via a communication line.
