Claims (1)

[Scope of utility model registration request] A photometric means for measuring subject brightness, a program diagram predetermined so that the shutter speed changes stepwise in a first step according to the subject brightness, and a first step for determining the shutter speed based on the photometric value. The shutter speed determination means 1 operates when the photometric value changes before and after the point of change in the shutter speed in the program diagram, and the shutter speed is determined at a second step interval shorter than the first step. A second step is to control the shutter speed so as to gradually approach the shutter speed determined in the first step by changing the shutter speed.
a shutter speed determining means; and an aperture control means for controlling an aperture based on the photometric value and the shutter speed determined by the first or second shutter speed determining means. camera.
