Camera shaking prevention device and camera shaking warning device

摘要

There is disclosed a device for preventing the camera shaking, provided with a light metering circuit for receiving the light from an object and releasing luminance signal corresponding to the luminance of the object; a detection circuit for detecting the camera shaking at phototaking operation; a counter for counting the number of phototaking operations identified as involving camera shaking and the number of phototaking operations identified as not involving camera shaking; a discriminator for comparing the above-mentioned numbers and discriminating the relation of the numbers; and an exposure control circuit for varying the shutter time, calculated from the luminance signal, to a shorter shutter time if the count of phototaking operations identified, by the discriminator, as involving camera shaking is larger than the count of phototaking operations identified as not involving camera shaking.
