<p>PURPOSE:To secure image blurring preventing operation by storing information corresponding to the state of an image blurring detecting means in the specified state of an optical equipment and controlling an image blurring preventing means in response to the information. CONSTITUTION:At the time of setting a calibration mode, the mirror-up of a camera is started and the result by a shake detecting sensor 5 fetched by timer interruption processing is successively fetched in a waveform memory means 29, and when the mirror-down thereof is completed, the fetching operation is finished. Therefore, sensor error waveform in the still placed state of the camera is fetched in the memory means 29. Meanwhile, in an ordinary photographing state, the memory value of the memory means 29 is subtracted from the value of a register where the result of the data of the sensor is set, and the obtained value is set in the register again. Therefore, the amount of an error signal previously stored in the memory means 29 is subtracted from a camera shake signal + error signal outputted from the sensor 5, so that the real camera shake signal is set in the register.</p> |
