Claims
- 1. A camera, in which a film having a data recording portion can be loaded, said camera comprising:
- colorimetric means having three light receiving portions differing in spectral sensitivity, for measuring a tone of light surrounding an object to be photographed based on an output from the three light receiving portions, said light receiving portions being arranged on a front portion of the camera and arranged so as to receive light at a range larger than an angle of a photographed view;
- color correction amount determining means for determining a color correction amount during a printing operation based on an output of said colorimetric means;
- recording means for recording data as to the determined color correction amount, on the data recording portion of the film;
- flash light emission means for radiating flash light onto the object during an exposure operation of the camera;
- photometric means for measuring a brightness of said object at one of a range roughly equal to the angle of the photographed view and a range of a part of the angle of the photographed view, and for outputting brightness data of the object;
- ratio determining means for determining a ratio of surrounding light to said flash light with respect to the object during the exposure operation which employs the flash light emission means, by using one of the brightness data and data based on said brightness data; and
- color correction amount changing means for changing an output of said color correction amount determining means in accordance with the determined ratio of the surrounding light to the flash light.
- 2. A camera according to claim 1, wherein:
- a light receiving range of each of said light receiving portions includes a range of the angle of the photographed view; and
- a center of each of the light receiving ranges is set to be higher than a center of the angle of the photographed view.
- 3. A camera comprising:
- a camera main body in which a film having a data recording portion is loaded;
- photometric means for measuring a brightness of an object to be photographed at one of a range roughly equal to an angle of a photographed view and a range of a part of the angle of the photographed view, and for outputting brightness data of the object;
- flash light emission means for radiating flash light onto the object during an exposure operation of the camera in accordance with the object brightness data;
- colorimetric means for measuring a color tone of surrounding light, a colorimetric range of the colorimetric means being set to include said angle of the photographed view and to be larger than the angle of the photographed view so as to avoid influence of the color tone of the object within the angle of the photographed view;
- first color correction data output means for calculating the measured tone and a preset reference color tone, and for outputting first color correction data;
- ratio referring means for table-referring a ratio of the surrounding light to the flash light with respect to said object during the exposure operation which employs the flash light emission means, by using one of the brightness data and data based on the brightness data;
- second color correction data output means for multiplying the first color correction data by the ratio obtained by said ratio referring means, and for outputting second color correction data; and
- recording means for selecting said first color correction data when said exposure operation is performed without using said flash light emission means, for selecting the second color correction data when said exposure operation is performed by using the flash light emission means, and for recording the selected color correction data on the data recording portion of the film while the film is wound up.
- 4. A camera, in which a film having a data recording portion is used, said camera comprising:
- an electronic flash light unit for radiating flash light onto an object to be photographed within a photographic region;
- colorimetric means for measuring a color tone of light surrounding the object, the colorimetric means being arranged on a front portion of said camera, a colorimetric range of the colorimetric means being set such that the colorimetric means measures light at a range larger than said photographic region;
- calculating means for calculating a color correction amount by comparing the measured color tone with a predetermined reference color tone level;
- ratio determining means for determining a ratio of external light to said flash light with respect to said object when said electronic flash unit is used during an exposure operation of the camera, by using at least one of data including a brightness of the object, a distance to the object, an exposure time with respect to a film surface, and an aperture value of a photographic optical system;
- color correction amount changing means for changing an output of said ratio determining means in accordance with said ratio of the surrounding light to the flash light; and
- recording means for recording a color correction amount changed by said changing means on said data recording portion of the film.
- 5. A camera according to claim 4, wherein said recording means executes a recording operation on said data recording portion of the film while the film is wound up.
- 6. A camera, in which a film having a data recording portion is usable, said camera comprising:
- colorimetric means, arranged on a front portion of the camera, for measuring a color tone of light at a predetermined range which includes an angle of a photographed view and which is larger than the angle of the photographed view;
- color correction amount determining means for determining a color correction amount during a printing operation based on an output of said colorimetric means;
- recording means for recording data based on the color correction amount, on said data recording portion of the film;
- flash light emission means for radiating flash light onto a region including the angle of the photographed view during an exposure operation of the camera with respect to a film surface;
- colorimetric means for measuring a brightness of one of the angle of the photographed view and a part thereof;
- calculating means for calculating a ratio of the flash light to environmental light of the angle of the photographed view during the exposure operation, by using one of output data of said colorimetric means and data based on the output data; and
- color correction amount changing means for changing an output of said color correction amount determining means in accordance with the calculated ratio output from said calculating means.
