ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a film scanner apparatus, and more particularly to a film scanner apparatus which is capable of taking or picking up pictures from plural kinds of films.
2. Related Art Statement
As such a film scanner apparatus dealing with pictures on plural kinds of films, there has been known a film player, exemplified by Japanese Unexamined Patent Publication No. 5-145838, which accepts a cartridge-housed film and a piece film (i.e. a film strip). However, the technical means disclosed in the Japanese Unexamined Patent Publication No. 5-145838 can cope with only films with the same scene size but not dealing with plural kinds of films having different scene sizes. For dealing with the plural kinds of films with different scene sizes, a converter lens would have to be mounted in accordance with a scene size to equalize the picking range on a solid-state image pick-up device such as CCD (Charge Coupled Device). However, this causes the size increase and complication of the apparatus which goes against making the apparatus more compact and cutting down its manufacturing cost.
OBJECTS AND SUMMARY OF THE INVENTION
Accordingly, it is a first object of the present invention to provide a film scanner apparatus which can cope with plural kinds of films with different scene sizes without leading to the size increase and complication of the apparatus.
A second object of this invention is to provide a film scanner apparatus which is capable of accomplishing an extremely easy-to-see picture display without displaying a useless and complicated picture outside a film scene even if scanning plural kinds of films with different scene sizes.
A third object of this invention is to provide a film scanner apparatus which is capable of visually confirming what kind of film corresponds to a target picture.
A fourth object of this invention is to provide a film scanner apparatus which is capable of visually confirming the film type corresponding to a target picture and further which is easy to use without destroying the performance in operation of a preview scene.
Briefly, a film scanner apparatus according to the present invention which allows the input of pictures of a plurality of films with different scene sizes, comprises:
a line sensor for reading out a picture on the film scene;
a scene size decision section for deciding (i.e. determining) the film scene size; and
a selection section for selecting effective pixels (picture elements) of the line sensor in accordance with a decision result of the scene size decision section,
wherein a picture display is made on the basis of the outputs from the effective pixels selected by the selection section.
These as well as other objects and advantages of the present invention will become further apparent from the following detailed explanation.
