Claims

[Scope of utility model registration request]

In shutter priority mode, the aperture value is calculated based on the preset shutter speed and brightness, the aperture value is calculated based on the calculated aperture value, and the aperture control is performed based on the calculated aperture value. In a camera that calculates the shutter time value based on a preset aperture value and brightness, and performs shutter control based on the calculated shutter time value, the preset shutter time is displayed in shutter priority mode, and the shutter time value is displayed in aperture priority mode. a first display that displays a preset aperture value; a second display that displays a calculated aperture value in shutter priority mode; and a calculated shutter time in aperture priority mode; A camera comprising: a display; and a control means for making the display color of the second display different between a preset value and a calculated value.
