Abstract:
1. A semiconductor device in which a driver chip having an analog circuit and a logic chip having a digital circuit are sealed in a single package, the driver chip including a vibration correction control unit for achieving an anti-shake function in an apparatus in which the semiconductor device is provided, and the logic chip including: a correction signal processing unit which obtains a value for vibration of the apparatus based on a vibration detection signal supplied from a vibration detection element to generate a correction signal; a control signal output unit which includes a plurality of types of signal output sections and outputs a vibration control signal in accordance with the correction signal to the vibration correction control unit, which executes vibration correction control for an optical component in accordance with vibration; a driver output terminal which outputs the vibration control signal to the driver chip; an external output terminal which outputs a control signal to an external circuit other than the driver chip; and an output switch unit which connects one signal output section among the plurality of types of signal output sections with the driver output terminal for outputting the vibration control signal corresponding to a driving unit which drives the optical component and connects another signal output section of the plurality of types of signal output sections with the external output terminal for outputting the control signal corresponding to the external circuit.
