摘要:
A semiconductor device with an anti-shake function includes a logic chip having a digital circuit which obtains a value for vibration of an apparatus based on a vibration detection signal supplied from a vibration detection element to generate a correction signal. The logic chip includes a correction signal processing unit which generates the correction signal, and a control signal output unit which outputs a vibration control signal in accordance with the correction signal to a vibration correction control unit which executes vibration correction control for an optical component in accordance with vibration. The correction signal processing unit includes a vibration computing unit which is capable of executing a plurality of stages of signal processing operations, by dedicated circuits, respectively, and which generates the correction signal from the vibration detection signal, and a central processing unit capable of executing desired computation processing to be performed by the vibration computing unit, and a signal obtained by executing all or a part of the computation processing to be performed by the dedicated circuits by the central processing unit is supplied as the correction signal to the control signal output unit.
