Picture blur-alarm device for a camera |
摘要 |
A picture blur-alarm device for a camera includes a photo-electric converter for time-sequentially sending brightness data including analog signal components which correspond to the brightness of the plurality of regions of an optical image of a foreground object, a comparator for comparing two successive brightness data time-sequentially issued from the photo-electric converter, and producing an output signal corresponding to the number of those of the analog signal components of a preceding brightness data which have different levels from corresponding analog signal components of a succeeding brightness data; and an alarm circuit which issues an alarm signal when an output signal from the comparator has a higher level than prescribed.
