ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a film image read apparatus which allows a monitor such as a TV set or personal computer to display a photographic image on a film having a recording portion for recording data other than image data.
Recently, cameras for taking photographs by using IX240 films and the like, which have magnetic recording portions, have come into widespread use. Various film read apparatuses for reading images on developed films and displaying them on monitors and the like have also been proposed.
In such a conventional film image read apparatus, regardless of the metering mode in which the camera used for photographing operation was set, a film image in a specific area is measured to adjust the electronic shutter of the CCD, the iris, and the gain.
In the above conventional film image read apparatus, however, if the metering scheme of the apparatus differs from that of the camera used for photographing operation, an object image looking good on a film may not look right on a monitor.
Assume that the camera performs partial metering for an object in a backlight condition, the appropriately exposed film image is read by the CCD with averaging metering, and the film image read with average metering is displayed on the monitor. In this case, a dark object image is displayed as if the object in the backlight condition was photographed with averaging metering.
FIG. 8
shows this state.
Referring to
FIG. 8
, reference symbol (a) denotes the image displayed on the finder of the camera, and (b) and (c), the film images obtained by appropriately photographing the object upon backlight correction. Since correction is performed in accordance with the object, the background is very bright. Reference symbol (d) denotes the image obtained by reading the film image data by the CCD with averaging metering. This object image is underexposed.
SUMMARY OF THE INVENTION
The present invention has been made to solve the above problems, and has as its object to provide a film image read apparatus which allows a monitor to reproduce a film image in accordance with the intention of the photographer, a control method therefor, an image processing apparatus, an image processing method, and a storage medium.
To solve the above problems and achieve the above object, a film image read apparatus of the present invention, according to its first aspect, is characterized by comprising:
information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, switching means for switching metering areas of the metering means for the film image, and control means for, when the read predetermined information includes metering mode information for photographing operation, controlling the switching means to switch the metering areas for the film image in accordance with the metering mode information.
A film image read apparatus of the present invention, according to its second aspect, is characterized by comprising:
information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, switching means for switching metering areas of the metering means for the film image, and control means for, when the read predetermined information includes flash information indicating whether flash means was used in photographing operation, controlling the switching means to switch the metering areas for the film image in accordance with the flash information.
A film image read apparatus of the present invention, according to its third aspect, is characterized by comprising:
information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, switching means for switching metering areas of the metering means for the film image, and control means for, when the read predetermined information includes backlight determination information in photographing operation, controlling the switching means to switch the metering areas for the film image in accordance with the backlight determination information.
A film image read apparatus of the present invention, according to its fourth aspect, is characterized by comprising:
information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, switching means for metering areas of the metering means for the film image, and control means for, when the read predetermined information includes exposure correction amount information in photographing operation, controlling the switching means to switch the metering areas for the film image in accordance with the exposure correction amount information.
A method of controlling a film image read apparatus of the present invention is characterized as follows according to its first aspect.
There is provided a method of controlling a film image read apparatus including information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, and switching means for switching metering areas of the metering means for the film image, comprising: when the read predetermined information includes metering mode information for photographing operation, switching the metering areas for the film image in accordance with the metering mode information.
A method of controlling a film image read apparatus of the present invention is characterized as follows according to its second aspect.
There is provided a method of controlling a film image read apparatus including information read means for reading predetermined information, other than image information, which is recorded on a film, image read means for reading an illuminated film image, metering means for metering the illuminated film image, and switching means for switching metering areas of the metering means for the film image, comprising: when the read predetermined information includes flash information indicating whether flash means was used in photographing operation, switching the metering areas for the film image in accordance with the flash information.
