INCORPORATION BY REFERENCE
The disclosures of the following priority applications are herein incorporated by reference: JP 8-179223, filed Jul. 9, 1996 and JP 9-83008, filed Apr. 1, 1997.
BACKGROUND OF THE INVENTION
1. Field of Invention
The present invention relates to an image reading and readout system that reads the image of each frame of a long-type film, displays the image on a monitor screen, and provides a method of trimming the image.
2. Description of Related Art
The image reading system is composed of a film image reading device, or film scanner. The film scanner, under the control of a host computer, reads the image of a film negative or reverse film. The host computer collects image data and controls the display of the image on the monitor screen.
In recent years, new types of film have been proposed. One of these is a long type of film (referred to below as “roll film”) which is left in a film cartridge even after development. The roll film is equipped with a magnetic storage region in each frame. In each magnetic storage region, a photographic item is recorded when photography is performed. Print sizes C, H, and P are included in the photographic item.
The C size is called the classic size, and has an aspect ratio of 3:2. The H size is called the high-vision size, and has an aspect ratio of 16:9. The P size is called the panorama size, and has an aspect ratio of 3:1.
In addition to reading the image of each frame, the film image reading device also reads the magnetic information of each magnetic storage region. The host computer executes trimming processing of image data received from each frame, according to the aspect ratio determined by the print size included in the magnetic information, and then displays the image on the monitor screen.
Accordingly, in a conventional image reading system that handles roll film, not all of the image information of the frame read by the film image reading device is displayed on the monitor screen. Only the trimmed frame image, which was automatically trimmed according to the aspect ratio determined by the print size included in the magnetic information, is displayed on the monitor screen.
Sometimes the user sees the frame image displayed on the monitor screen and wants to add changes to the is print size set. during photography. However, a conventional display method ignores part of the image information on the film, as explained above.
Accordingly, the user cannot freely select, on the monitor screen, all of the image information for the film. Instead, the user can only change the frame image displayed according to the aspect ratio determined by the print size set during photography. Therefore, it is difficult to obtain a frame image of a satisfactory size.
Further, in a conventional display method, the frame image is displayed on the monitor screen based on the aspect ratio determined by the print size. Because the print size is only set during photography, when the user changes the image size, the user must do so without knowing what the print size was originally set to. This also points out why it is difficult in a conventional display method to obtain a frame image of a satisfactory size.
SUMMARY OF THE INVENTION
The present invention has an objective to provide an image reading display system equipped with a display method that performs size changes on the monitor screen, effectively using all of the image information on the film, and that can easily scan the final image resulting after changes have been added.
According to a first embodiment, an image reading system is provided having an image reading device for reading the image, frame-by-frame, of long-type film provided with an image storage region and a magnetic storage region in each frame, and outputting an image signal. A magnetic information reading device reads the magnetic information of the magnetic storage region, and outputs a magnetic signal. A display device displays an image and a control device creates a first image data corresponding to roughly the entire body of the image of the image storage region, based on the image signal. The control device also creates a second image data corresponding to the image of the image storage region, which has been trimmed based on the image signal and information related to trimming that is included in the image signal and the magnetic signal. The control device further displays a first image corresponding to the first image data, and a second image corresponding to the second image data, on the display device.
The image reading system may also include a trimming size setting device for setting the trimming size of the image of the image storage region, and for outputting a trimming signal. The control device converts the second image data to third image data based on the image signal and the trimming signal, and displays a first image corresponding to the first image data and a third image corresponding to the third image data on the display device.
The image reading system may still further include a magnetic information writing device for writing the trimming size information set via the trimming size setting device into the magnetic storage region.
According to a second embodiment, an image reading system includes an image reading device for reading the image, frame-by-frame, of long-type film provided with an image storage region and a magnetic storage region in each frame, and outputting an image signal. A magnetic information reading device reads the magnetic information of the magnetic storage region and outputs a magnetic signal. A display device displays an image and a control device creates a first image data corresponding to roughly the entire body of the image of the image storage region, based on the image signal. The control device also creates first trimming frame data, based on the image signal and on information relating to trimming, which is included in said image signal and the magnetic signal. The control device also displays a first image corresponding to the first image data on the display device and displays a first trimming frame corresponding to the first trimming frame data on the display device, superimposed on the first image.
The image reading system may further include a trimming size setting device for setting the trimming size of the image of the image storage region, and for outputting a trimming signal. The control device converts the first trimming frame data, based on the image signal and the trimming signal, into second trimming frame data, and displays a second trimming frame corresponding to the second trimming frame data on the display device, superimposed on the first image.
The image reading system may still further include a magnetic information writing device for writing trimming size information set via the trimming size setting device into said magnetic storage region.
The image reading system may also include an image reading device having the magnetic information reading device and the magnetic information writing device and a host computer having the display device, the control device, and the trimming size setting device.
The image reading system may also include an image size designating device for setting enlargement or reduction with regard to the image within the trimming frame and for outputting enlargement data or reduction data. A magnetic information device writes in the magnetic storage region, where the control device enlargement converts or reduction converts the first image data into second image data based on the enlargement data or reduction data, displays the second image corresponding to the second image data on the display device, and writes the enlargement data or reduction data in the magnetic information writing device.
The image reading device reads each frame of the image, frame by frame, of the long-type film that is equipped with an image storage region and a magnetic storage region in each frame, and outputs an image signal. The magnetic information reading device reads the magnetic information of the magnetic storage region and outputs a ma
