A charge-coupled device has a plurality of photodiode arrays, a plurality of storage electrodes, a pluratity of shift gates, a plurality of reset terminals, and a plurality of shift terminals, which can be operated at different timings. Object images detected by the charge-coupled device at a certain time interval are compared for camera shake detection.

A camera shake detector comprising: a light detector group for photoelectrically converting an object image formed by an optical system; a monitoring light detector disposed in the vicinity of said light detector group for photoelectrically converting the average brightness of the object image; clear pulse generator means coupled to said monitoring light detector for generating a clear pulse to clear said monitoring light detector and said light detector group to a certain level; decision means coupled to said monitoring light detector for ascertaining whether an output from said monitoring light detectro drops below a reference voltage; shift pluse generator means coupled to said monitoring light detector for issuing a shift pulse to shift stored charges from said light detector group to a transfer unit when the output from said monitoring light detector is found to be lower than the reference voltage by said decision means, and for issuing a second shift pulse to shift stored charges from said light detector group to the transfer unit again after said first-mentioned stored charges have been transferred from said light detector group; transfer pulse generator means for generating a transfer pulse to transfer the stored charges from said light detector group; time equalizer means for equalizing a time period between a first cliear pulse and a first shift pulse to a time period between a second clear pulse and a second shift pulse; and a comparator/processor for comparing first and second image output signals from said light detector group to ascertain whether there is a camera shake.
