CPC Class H04N

A vehicle wheel alignment system has a plurality of cameras, each camera for viewing a respective target disposed at a respective wheel of the vehicle and capturing image data of the target as the wheel and target are continuously rotated a number of degrees of rotation without a pause. The image data is used to calculate a minimum number of poses of the target of at least one pose for every five degrees of rotation as the wheel and target are continuously rotated the number of degrees of rotation without a pause. At least one of the cameras comprises a data processor for performing the steps of preprocessing the image data, and calculating an alignment parameter for the vehicle based on the preprocessed image data.

An image sensor may include one or more pixels having a charge steering structure that may selectively route charge from a photodiode to increase the dynamic range of the pixel. The charge steering structure may be a coupled gate structure that routes overflow charge to a voltage supply and to one or more integrating storage structures during an exposure period. The charge steering structure may be two integrating storage structures directly connected to the photodiode that each integrate charge generated by the photodiode in an alternating fashion during an exposure period. Storage structures and transistors within the charge steering structure may receive control signals, which may be asserted in a mutually exclusive manner. Pixels may also include a dual-gain structure, which may provide additional charge storage capacity.

An exemplary embodiment of the present invention includes a PCB (Printed Circuit Board) mounted with an image sensor, a holder member mounted at the PCB to support a lens module, movable lens concentrically arranged with the lens module, a first actuator compensating movement of an image captured by the image sensor by moving the movable lens, and a gyro sensor unit integrally formed with the first actuator to detect rotation of trajectory in response to movement of an electronic device mounted with the camera module.
