摘要： Systems and methods to achieve an auto-focus camera with a movable lens barrel having a mechanic shock detection capability combined with a re-initialization of the camera module have been disclosed. This re-initialization may comprise moving the lens barrel displaced by the shock to a home position. In a preferred embodiment of the invention a motor with integrated position detection has been used. In a normal operation the position detection feature senses the actual position of the lens, e.g. during auto-focusing of the lens barrel, and provides this position information to a control unit which is controlling the movement of the lens barrel to a target position. In case of a mechanic shock, e.g. if the camera module drops to ground, the control unit detects an extreme rapid displacement of the lens barrel and initiates a re-initialization of the camera module.

摘要： Systems and methods are disclosed for x-y tables wherein rolling elements of rolling-element bearings are transferring electrical energy between a fixed part of the x-y table and a movable part of the x-y table. The electrical energy transferred could be power to electrical devices as well as signals to and from devices on the movable part of the x-y table. Electrically conducting rolling elements are moving on electrically conducting grooves on the fixed and movable part of the x-y table. Conductor tracks on the fixed and movable part are connected to the grooves and to devices on the movable platform. In a preferred embodiment of the invention the x-y table is part of a camera wherein linear motors, preferably with integrated position sensing, are moving the x-y table back to a home position in case of a dislocation due to a mechanical shock. The invention allows an exact and fast positioning of an x-y table without requiring a flexible cable. The rolling-element bearings could be ball bearings, roller bearings, needle bearings, or other kind of bearings having electrically conductive rolling elements.

摘要： Systems and methods to achieve an auto-focus camera module having a retention system with low friction have been disclosed. A magnetic retention system holds the carrier of the camera module, the ball bearings, and the movable lens barrel together. In case of a major mechanical shock the force of the magnetic retention system may not be sufficient to hold the parts together. Therefore a hook, which is deployed on a fixed part of the carrier of the camera module, is introduced in order to hold the parts together when a mechanical shock occurs. The hook does only engage in the movable lens barrel in a shock condition, the hook does not touch the lens barrel under normal operation conditions, hence not causing any friction if no shock occurs.

摘要： In camera systems with more than one aperture plane, light from different object points can be shaded by either the lens' pupil, the system's aperture or both. depending on pupil and aperture diameters, separation and camera system field of view. In an aperture shading correction (ASC) algorithm, the shading that results from the convolution of the lens' pupil function and its aperture function is determined over the image plane for any given pupil and aperture diameter and separation. A shading correction function is then calculated, and/or its parameters are determined, that will undo the adverse relative illumination degradations that result from the tandem pupil and aperture. This can be done in separate color planes. This can be done in tandem with standard lens shading correction that must also be corrected for (i.e., the lens shading correction (LSC) can be performed in the sensor for the case of no aperture shading, then the ASC multiples the LSC during aperture shading). Aperture shading will also impact SNR and MTF, and as such the tuning of these parameters will also benefit from ASC knowledge.

摘要： Systems and methods using the same to achieve a camera having precise timing of a camera shutter, which can be used also for a controllable aperture, are disclosed. The aperture can be controlled continuously and can therefore be used for video cameras. The shutter system is controlled by a feedback loop. The shutter blades are moved by at least one linear motor, a position sensor senses the actual position and speed of the blades. The movement of the blades can be stopped any time to get an aperture desired. For capturing an image in a first step a global reset is opening (activating) every pixel of the image sensor after the shutter is opened. In order to achieve a short active light exposure time (below 1 ms), after the global reset, the mechanical shutter invented closes rapidly after a defined active light exposure time. An active light exposure time is the time span between the image sensor is activated and the mechanical shutter is closed. In order to achieve a precise timing the shutter of the present invention uses electronic control and a feedback loop to control the actual position of the shutter.

摘要： A blended approach to achieving best system-level autofocus in a camera module where conventional mechanical autofocus techniques (and their associated filter algorithms) are used in conjunction with softlens autofocus techniques. In this manner, the mechanical autofocus approach needs only get close to the best focus position (thereby relaxing its tolerances) and then the softlens autofocus approach takes over and completes the fine tuning of the best focus (thereby relaxing its capabilities requirements).

摘要： A horological motor of the Lavet motor concept is used to form an actuator to control movement of a lens system to reduce power consumption in digital camera units used in various electronic equipment, e.g. PDA's, mobile phones, digital still cameras and camcorders, and as a result increase battery life. The coils of the horological motor are driven with CMOS I/O signals eliminating the need for high current motor drivers and allowing the integration of all picture capture functions, including the light sensitive pixel array, into a single chip to form a system on chip implementation. A plurality of actuators is used to control a lens system comprising auto focus, zoom and shutter and iris functions. A gear transmission system is used to allow the motor of the actuator to move in micro step, which allows calibration of the motor against mechanical barriers.

摘要： A method for forming a pixel image sensor that has a high shutter rejection ratio for preventing substrate charge leakage and prevents generation of photoelectrons within a floating diffusion storage node and storage node control transistor switches of the pixel image sensor. The pixel image sensor that prevents substrate charge leakage of photoelectrons from pixel image sensor adjacent to the pixel image sensor. The pixel image sensor is fabricated on a substrate with an isolation barrier and a carrier conduction well. The isolation barrier formed underneath the floating diffusion storage node allows effective isolation by draining away the stray carriers and preventing them from reaching the floating diffusion storage node. The carrier conduction well in combination with the deep N-well isolation barrier separates the pinned photodiode region from the deep N-well isolation barrier that is underneath the floating diffusion storage node.
