Abstract
PURPOSE:To eliminate the photometric error caused by the adverse incident light given through a finder eyepiece, by storing the luminance of a subject obtained before the mirror is stored in a storage means by a setting operation of a self- timer and controlling automatically the exposure value by the output of the storage means. CONSTITUTION:An eyepiece shutter set signal source using a switch S13 incorporating a resistance R7 and a self-timer set signal source having a switch S6 are connected to the input terminal of a gate G18 to control the output of the signal of a switch S2 which functions with the 2nd stroke of the pressure of a shutter button through the gate G18. The signals supplied from the switches S2 and S6 are applied to the gate G18 via inverters I9 and I8. At the same time, the eyepiece shutter is set. In such a case, the switches S6 and S13 are closed. Thus, the gate G18 is closed to delivery the synchronizing signal obtained right before the mirror-up state through an OR gate G19. Thus the photometric action is discontinued.
