Abstract

A solid-state image pickup device including a driver-control unit configured to control the operation timing of a pulse-driven actuator driver based on the read timing of the sensor of a solid-state image pickup element is provided.

Claims

1. A solid-state image pickup device comprising:

driver-control means for controlling operation timing of a pulse-driven actuator driver based on read timing of a sensor of a solid-state image pickup element.

2. The solid-state image pickup device according to claim 1, wherein the driver-control means synchronizes the operation timing with the read timing, and sets a cycle of a pulse signal of the actuator driver to an integral multiple and/or an integral submultiple of a read cycle of the sensor.

3. The solid-state image pickup device according to claim 2, wherein the driver-control means adjusts a phase of the pulse signal of the actuator driver.

4. The solid-state image pickup device according to claim 3, wherein the driver-control means changes the phase of the pulse signal of the actuator driver so that sampling timing of a read circuit of the sensor does not overlap an edge of the pulse signal.

5. The solid-state image pickup device according to claim 1, wherein the driver-control means performs control so that a pulse signal of the actuator driver does not occur when sampling timing of a read circuit of the sensor overlaps an edge of the pulse signal.

6. The solid-state image pickup device according to claim 1, wherein the actuator driver is provided inside the solid-state image pickup device.

7. The solid-state image pickup device according to claim 6, wherein the actuator driver dynamically changes a drive capacity.

8. The solid-state image pickup device according to claim 1, wherein the driver-control means performs feedback control inside the solid-state image pickup device, so as to generate a pulse signal of the actuator driver by using a signal read from the sensor.

9. A solid-state image pickup device comprising:

a driver-control unit configured to control operation timing of a pulse-driven actuator driver based on read timing of a sensor of a solid-state image pickup element.
