ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a photographing device, a film accommodating body, a film system, a photo lab apparatus, a photographing method by the photographing device, and an image processing method by the photo lab apparatus.
2. Description of the Related Art
Conventionally, in photographing using a high sensitivity film, there is the tendency for an image to easily be overexposed. As a result, because the negative density is high, and printing takes much time at a photo lab or a DPE shop, which is problematic.
The negative density can be calculated from the exposure amount at the time of photographing. However, under the present circumstances the negative density is not known until the film is developed at a photo lab or a DPE shop and passed through a printer or a scanner. There is no way for the photo lab to handle such situation.
Further, at recent small photo labs using a film scanner in place of an optical printer, processing such as changing the tone at the time of printing, trimming by electronic zooming, and the like are possible. However, it is hard for a photographer to give instructions for each frame to the photo lab at the time of requesting development. In practice, because the photographer has to reprint images after receiving the finished prints, it is wasteful in terms of costs and time, and is inefficient.
On the other hand, if the sensitivity is set to be high at the camera in order to avoid overexposure, the object which is the main object such as the face of a person or the like becomes dark due to backlighting, and the balance with brightness around the main object is lost.
Alternatively, in the case of indoor photographing, photographing with a night view as the background, or the like, if an electronic flash is used, the modulated light amount of the electronic flash and the exposure amount of the background are out of balance, and only the object is bright and the background is slightly underexposed. Thus, as a result, the brightness of the object and the background are out of balance.
A method in which these problems are avoided by the photographer himself/herself manually changing the sensitivity setting of the camera has not been realized due to the trouble and the ease of making mistakes at the time of photographing. Among recent electronic cameras, there are cameras in which sensitivity setting cannot be manually carried out.
SUMMARY OF THE INVENTION
The present invention has been achieved in consideration of the above-described circumstances, and an object of the invention is to provide a photographing device and a photographing method characterized by having an identifier detecting component which detects an identifier showing that a light-responsive component can be used in photographing with a sensitivity of the light-responsive component set to a sensitivity different from the indicated sensitivity.
Further, another object of the invention is to provide a photographing device further having a recording component which records sensitivity information showing a sensitivity set at the time of photographing, and to provide a photo lab apparatus and an image processing method which, on the basis of the sensitivity information, process images photographed by the photographing device. Moreover, an object of the invention is to provide a film accommodating body and a film system which can be loaded in the photographing device.
Further, an object of the invention is to obtain appropriate exposure conditions by using the light-responsive component, which can be used in photographing with the sensitivity set to a sensitivity different from an indicated sensitivity, and by automatically switching the sensitivity setting of the photographing device in accordance with photographing conditions.
As a technique relating to the invention, for example, Japanese Patent Application Laid-Open (JP-A) No. 9-80695 discloses a film having a bar code that shows film characteristics including the sensitivity, in order to be able to set the exposure conditions by the camera sensing the bar code.
In order to achieve the above-described objects, a photographing device of a first aspect is characterized by comprising an identifier detecting component which detects an identifier showing that a light-responsive component responsive to light from an object can be used in photographing with a sensitivity different from an indicated sensitivity being set as a sensitivity of the light-responsive component.
Namely, the photographing device is characterized by comprising an identifier detecting component which detects an identifier showing that a light-responsive component responsive to light from an object can be used in photographing with a sensitivity different from an indicated sensitivity being set as a sensitivity of the light-responsive component. Therefore, in accordance with the photographing device, it can be identified whether or not the light-responsive component can be used in photographing with the sensitivity set to a sensitivity different from the indicated sensitivity, in order to inform the user of the sensitivity of the light-responsive component.
In a second aspect, there is the feature that the identifier detecting component of the first aspect comprises a first identifier detecting component which detects the identifier, and a second identifier detecting component which detects an indicated sensitivity identifier showing the indicated sensitivity.
Namely, the identifier detecting component has the first identifier detecting component which detects an identifier, and the second identifier detecting component which detects an indicated sensitivity identifier showing the indicated sensitivity. Therefore, an identifier shown by a position or a shape which is different from that of the indicated sensitivity identifier is detected by the first identifier detecting component, so that it can be identified whether or not the light-responsive component can be used in photographing with the sensitivity set to a sensitivity different from the indicated sensitivity.
In a third aspect, the photographing device of the first aspect may have a luminance detecting component which detects a luminance of the object; a sensitivity setting component which sets a sensitivity on the basis of the luminance of the object detected by the luminance detecting component and the identifier detected by the identifier detecting component; and a photographing component which photographs the object on the basis of the sensitivity set by the sensitivity setting component.
Namely, the photographing device has the luminance detecting component which detects the luminance of the object, the sensitivity setting component which sets a sensitivity on the basis of the luminance of the object detected by the luminance detecting component and the identifier detected by the identifier detecting component, and the photographing component which photographs the object on the basis of the sensitivity set by the sensitivity setting component. Accordingly, for example, by setting the sensitivity of the photographing device to be high in outdoor photographing in the daytime in which it is easily for overexposure to occur, or the like, the exposure amount is reduced, and the negative density can be prevented from becoming high.
In a fourth aspect, there is the feature that the light-responsive component in the photographing device of the first to third aspects has the identifier.
Namely, the light-responsive component has the identifier, and the identifier detecting component of the photographing device detects the identifier of the light-responsive component, so that it can be identified whether or not the light-responsive component can be used in photographing with the sensitivity set to a sensitivity different from the indicated sensitivity.
In a fifth aspect, the light-responsive component in the photographing device of the third or fourth aspect is formed so as to be able to record sensitivity information showing the sensitivity at the time of ph
