<p>PURPOSE:To automatically obtain a photograph meeting the image of that time zone at the time of taking the photograph of an evening or morning scene by providing an exposure value calculating means and making the means to calculate exposure values based on the color temperature and object distance. CONSTITUTION:One part of the output of a photometry element 11 is converted into a luminance value by means of a luminance information converting device 21 and inputted to an exposure value calculating means (CPU) 23 and the other part is converted into a color temperature by means of a color temperature information converting device 22 and inputted to the CPU 23. From a photographing lens barrel 2, object distance information and lens data, such as stop value information, etc., stored in an in-lens ROM are inputted to the CPU 23. The CPU 23 calculates the optimum exposure value based on the inputted information. Since the CPU 23 regards a scene as an evening or morning scene when the object distance is long and color temperature is low and sets the exposure to a lower value, a photograph meeting the image of that time zone can be obtained.</p> |
