ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to scanner systems and, more particularly, to a scanner system which converts image information of a film to electronic image information.
2. Related Art And Prior Art Statement
Conventionally, in Japanese Patent Publication No. SHO 56-7631 and Japanese Utility Model Publication No. SHO 63-36768, technical means is disclosed which reads a film by a one-dimensional sensor to convert the film to a video signal. Further, in recent years, proposed have been a film-image fetching apparatus such as a FOTOVIX (trade name: manufactured by Kabushiki Kaisha Tamuron) or the like, and a system for fetching image information of the film by an image pickup element such as a two-dimensional CCD or the like due to a macro mode or the like such as still video or the like.
Moreover, in Japanese Patent Laid-Open No. HEI 2-20170, technical means is disclosed which pre-scans a reading image to set a reading condition.
Meanwhile, U.S. Pat. No. 4,965,626 discloses a film capable of recording various information (date, correcting values, type or kind and the like) upon photographing.
Nevertheless, in the technical means due to Japanese Patent Publication No. SHO 56-7631, Japanese Utility Model Publication No. SHO 63-36768 and the like, in a case where an image of the film is electronically imaged, it is necessary to perform setting of brightness, setting of trimming, and the like by a hand or manual operation. Particularly, in a case where correction such as exposure correction or the like is performed upon film photographing, it is difficult for general users to conform to the condition. Furthermore, for the technical means which uses the above-described two-dimensional CCD, it is necessary to use a large-size two-dimensional sensor in order to improve resolution. This causes an increase in camera size and an increase in cost.
Further, in the technical means due to the above-described Japanese Patent Laid-Open No. HEI 2-20170, in a case where pre-scanning is performed to set various kinds of conditions, surplus or extra operation is required. Moreover, in a case where exposure correction is performed, or the like, advantages of the exposure correction cannot be expected.
Meanwhile, in a case where the image information of the film due to the aforesaid U.S. Pat. No. 4,965,626 is read by the scanner or the like, various information recorded as above mentioned cannot be fed-back. Thus, U.S. Pat. No. 4,965,626 has a problem that an adequate electronic image cannot be reproduced or cannot reappear.
OBJECTS AND SUMMARY OF THE INVENTION
It is a first object of the invention to provide a scanner system which automatically performs setting of a condition adequate or optimum for electronic imaging of a film, by a simple arrangement.
It is a second object of the invention to provide a scanner system which sets an image fetching condition of a scanner on the basis of information recorded onto a magnetic recording medium on a film, to obtain or produce an adequate electronic image similar to that upon film photographing, by a simple operation.
It is a third object of the invention to provide a scanner system which is capable of easily converting an image of a film to an adequate electronic image on the basis of trimming information which is recorded onto a magnetic recording medium on a film.
It is a fourth object of the invention to provide a scanner system which is capable of easily converting an image of a film to an adequate electronic image, on the basis of luminance information or intensity information which is recorded on a magnetic recording medium on the film.
It is a fifth object of the invention to provide a scanner system which is capable of easily converting an image of a film to an adequate electronic image, on the basis of light-source information which is recorded on a magnetic recording medium on the film.
It is a sixth object of the invention to provide a scanner system which can optimize an integrating time of a photoelectric conversion element, the number of added pixels, brightness of a light source, feeding speed of a film, and the like, on the basis of information which is recorded on a magnetic recording medium on the film, so as to be capable of easily converting an image of the film to an adequate electronic image.
Briefly, according to the invention, there is provided a system for reading an image formed on a silver-salt film, comprising:
(a) magnetic information reading means for reading magnetic information recorded on a magnetic recording medium on the film;
(b) feeding means for feeding the film;
(c) illuminating means for irradiating light to the image formed on the film;
(d) filter means arranged between the illuminating means and the film;
(e) photoelectric conversion means for receiving the light from the illuminating means, which is passed through the film, to convert the image formed on the silver-salt film to an electric signal;
(f) memory means for storing an image signal from the photoelectric conversion means; and
(g) control means for controlling at least one of the feeding means, the illuminating means and the photoelectric conversion means, on the basis of information of the information reading means.
These as well as other objects and advantages of the present invention will become further apparent from the following detailed explanation.
