摘要： An imaging apparatus which can correct a shaking of the hand whether a moving picture is taken or a still picture is taken. Exposure is carried out within a shorter time than a predetermined exposure time to output a charge. Exposure and delivery of charge is carried out plural times to accumulate charges. An address for accumulation is changed in accordance with information of a shaking occurring within the shorter time and a signal due to the shaking and a signal before the shaking are accumulated at the address. Alternatively, a camera-shake is detected by using a sensor such as a gyroscope adapted to detect an angular velocity or an acceleration of a shaking of the imaging apparatus itself.

摘要： In the imaging apparatus, an image signal derived from an imaging element is supplied to color signal producing means so as to be separated into a R(red) color signal, a G(green) color signal and a B(blue) color signal. These R, G, B signals are supplied to color-depending frequency component changing means. While predetermined information has been stored in a memory with respect to each of the R signal, the G signal and the B signal, and the predetermined information is used in order to change a signal level of a high frequency component every R, G, B signals, the color-depending frequency component changing means extracts a high frequency component from each of the R signal, the G signal and the B signal, and then, corrects frequency components of these extracted high frequency components in such a manner that the corrected frequency characteristics may constitute relevant signals.
