Abstract: A developed photographic film including a magnetic layer is transported up to an image reading part so as to read a film image thereon. The film images are sequentially displayed on a TV monitor in accordance with automatic regenerating information. The automatic regenerating information is previously input as information used for sequentially and automatically regenerating a plurality of the film images. Moreover, magnetic information is used as a part of the automatic regenerating information. This magnetic information is recorded in the magnetic layer by a camera at the time of photographing. As a result, an operation is simplified at the time of inputting the automatic regenerating information.

A line sensor is provided in which photoelectric transfer elements are arranged in a direction perpendicular to a feeding direction of a long roll of developed film for a still camera, the film is fed at the first speed continuously to take the rough image data of all frames through the line sensor, and the taking environment for every frame is detected based on the taken rough image data.

Abstract: The present invention is directed to ultraviolet shielding composite fine particles having transparency in a visible light region include (a) matrix particles comprising an aggregate of primary particles having an average particle diameter of from 0.001 to 0.3 .mu.m, the aggregate being formed while the primary particles retain their shapes; and (b) daughter particles having an average particle diameter of from 0.001 to 0.1 .mu.m, the daughter particles being dispersed in and supported by the matrix particles. In the composite fine particles, the daughter particles have a smaller band gap energy than the particles constituting the matrix particles and are capable of absorbing ultraviolet light, and the resulting ultraviolet shielding composite fine particles have substantially no catalytic activity.

The composite fine particles are produced by preparing a liquid mixture containing a mixture comprising starting materials for matrix particles and for daughter particles; forming droplets from the liquid mixture; and drying the formed droplets and/or pyrolyzing starting materials for pyrolysis therein.

Abstract: A roll of developed still photographic film feeds toward an image capturing part. The image capturing part captures the image data of plural frames. An index image, which is composed of plural frames, is made in accordance with the captured image data of plural frames, and the index image is displayed on a display. When the index image is displayed, the format information relating to an aspect ratio of each frame, which is recorded in the film, is read. An image processing conforming to the format information of each frame is executed in accordance with the read format information, so that the aspect ratio of each frame in the index image can be seen. Only an image area, which is required for display and printing, is read according to the format information relating to the aspect ratio of each frame. As a result, the pixels of the line sensor can be used effectively.

Abstract: A film image input method and device uses a line sensor as an image sensor to reduce the cost, and the image data can be corrected in accordance with the taking environment, which occurs in a case of using the line sensor, for every frame. The line sensor includes photoelectric transfer elements arranged in a direction perpendicular to a feeding direction of a long roll of developed film for a still camera. The film is fed at a first speed continuously to take the rough image data of all frames through the line sensor, and the taking environment for every frame is detected based on the taken rough image data. Thereafter, when reproducing one frame, the film is fed at the second speed, whereby the fine image data of the desired frame are adjusted in accordance with the detected taking environment of the frame and stored in the CCD buffer, and then the image signals are output to the TV monitor based on the stored fine image data.

Abstract: A black-type recording liquid, even when used for ink-jet recording instruments or for recording with ordinary writing instruments on plain paper, is capable of forming a recorded image with high printing quality: high density, excellent color tone, and excellent water and light resistance, and is highly stable when stored for a long time.

Image data can be corrected in accordance with the taking environment, which occurs in a case of using the line sensor, for every frame. A line sensor is provided in which photoelectric transfer elements are arranged in a direction perpendicular to a feeding direction of a long roll of developed film for a still camera. The film is fed at the first speed continuously to take the rough image data of all frames through the line sensor. The taking environment for every frame is detected based on the taken rough image data. Thereafter, when reproducing one frame, the film is fed at the second speed which is lower than the first speed, whereby the fine image data of the desired frame are adjusted in accordance with the detected taking environment of the frame and stored in the CCD buffer. Then, the image signals are output to the TV monitor based on the stored fine image data.

Abstract: When a film cartridge storing a developed film including a magnetic layer is mounted in an electronic viewer, the film is pulled out from the cartridge, and a forward end of the film is wound around a winding axis. A film transport is controlled in accordance with a detection signal generated by a frame detector every detection of the frame, so that a film image of the film can be observed. At the same time, the viewer reads out magnetic information recorded in the magnetic layer, which corresponds to each film image. Contents of the magnetic information are displayed on an LCD of the viewer. As a result, a user can observe his desirable film image and the contents of the magnetic information corresponding the desired film image.

Abstract: A magnetic track on a photographic film is provided with a record region in which a renewal code or a flag indicating that a processing for an order to be completed is recorded. When print order information is renewed, the renewal code or the flag is renewed or cleared. As a result, it can be automatically judged whether the print order information recorded in the magnetic track is the same as one at the time of a previous order, and a processing at a laboratory can be automatically carried out. The print order information is classified into plural types of information including information to be rewritten for every order and information not to be rewritten for every order. At a laboratory, the print order information to be rewritten for every order is automatically deleted or reset before returning the photographic film to the user.
