Abstract:
A camera comprising:a light quantity sensor for sensing a quantity of reflected flash light which is emitted from a flash light source, reflected by an object and reaches to a plane to be exposed; a flash light controller for controlling a quantity of flash light emitted from the flash light source by stopping emission of the flash light with reference to the quantity of the flash light sensed by the light quantity sensor; a distance sensor for sensing a distance to the object; a luminance sensor for sensing a luminance of the object; an aperture value selector for selecting an aperture value of a taking lens corresponding to the luminance of the object or selection by an operator; a limit quantity calculator for calculating an upper limit and/or a lower limit of the quantity of the flash light which will be emitted from the flash light source with reference to the distance to the object and the aperture value selected by the aperture value selector; a quantity restrictor for restricting the quantity of the flash light which will be controlled by the flash light controller corresponding to the upper limit and/or the lower limit of the quantity of the flash light calculated by the limit quantity calculator; an input unit for inputting parameter information with respect to parameters which will affect an accuracy of the upper limit and/or the lower limit of the quantity of the flash light calculated by the limit quantity calculator; and a compensator for compensating the upper limit and/or the lower limit of the quantity of the flash light calculated by the limit quantity calculator corresponding to the parameter information.
