Abstract
A hand deviation correction apparatus of a simplified construction for correcting hand deviation effects over a wide frequency range in a hand-held video camera unit includes an oscillation quantity detection unit for detecting an oscillation quantity of a picture caused by wobbling of the video camera unit, a characteristics compensation unit for variably setting compensating frequency characteristics of an output signal of the oscillation quantity detection unit, a correction unit for correcting oscillations in the picture based upon an output signal of the characteristics compensation unit, a temperature detection unit for detecting the ambient temperature of the correction unit, and a compensation quantity calculating unit for calculating a quantity of compensation to be provided by the characteristics compensation unit based upon a detection signal from the temperature detection unit.
