Title: Photographing device
Inventor: FUJISAKI TATSUO
IPC: G02B27/64
Filed: 1990-02-27
Abstract: PURPOSE:To prevent the adverse effect of a signal from arising in a photographed image and a finder image by providing a judging means judging whether or not the detected information of a blurring detecting means is a proper blurring detecting signal. CONSTITUTION:A blurring quantity theta applied to an camera from outside is detected by the blurring detecting means 41 and outputted as a detected angular displacement theta. This angular displacement value is inputted to a CPU, multiplied by a proper coefficient by an arithmetic means 42 and converted into an instruction signal (x). The detected angular displacement value theta from the blurring detecting means 41 is monitored by the deciding means 48. When the absolute value of theta is larger than a preset value, by judging that it is a state detecting panning among 'improper shaking detecting signals', a driving signal - (X) is made equal to zero. Thus, the finder image passing through a photographic lens is prevented from becoming discontinuous and imparting sense of incongruity to a photographer.
