20090128639 | METHOD AND APPARATUS TO CORRECT DIGITAL IMAGE BLUR DUE TO MOTION OF SUBJECT OR IMAGING DEVICE - Signal processing techniques are applied to digital image data to remove the distortion caused by motion of the camera, or the movement of the subject being photographed, or defective optics, or optical distortion from other sources. When the image is captured, the effect of relative motion between the camera and the subject is that it transforms the true image into a blurred image according to a 2-dimensional transfer function. The 2-dimensional transfer function representing the motion is derived using blind estimation techniques or by using information from sensors that detect the motion. The transfer function is inverted and used to define a corrective filter. The filter is applied to the image and the blur due to the motion is removed, restoring the correct image.

20090244300 | METHOD AND APPARATUS FOR MOTION INVARIANT IMAGING - Object motion during camera exposure often leads to noticeable blurring artifacts. Proper elimination of this blur is challenging because the blur kernel is unknown, varies over the image as a function of object velocity, and destroys high frequencies. In the case of motions along a 1D direction (e.g. horizontal), applicants show that these challenges can be addressed using a camera that moves during the exposure. Through the analysis of motion blur as space-time integration, applicants show that a parabolic integration (corresponding to constant sensor acceleration) leads to motion blur that is not only invariant to object velocity, but preserves image frequency content nearly optimally. That is, static objects are degraded relative to their image from a static camera, but all moving objects within a given range of motions reconstruct well. A single deconvolution kernel can be used to remove blur and create sharp images of scenes with objects moving at different speeds, without requiring any segmentation and without knowledge of the object speeds. | 10-01-2009 |

20150350549 | OPTICAL IMAGE STABILIZATION CALIBRATION - In some embodiments, a camera actuator module includes a linear actuator motor for moving a lens assembly, a position sensor coupled to the lens assembly, a mechanical end stop mounted in the path of motion of the lens assembly, and a non-transitory storage medium storing program instructions. In some embodiments, the program instructions are computer-executable to implement exciting, using the linear actuator motor, a mechanical resonance in the camera actuator module calculated to cause the lens assembly to move to an overload displacement by powering the linear actuator of the camera actuator module at a resonant frequency of the camera actuator module, measuring, using the position sensor, a current maximal displacement of the lens assembly during the exciting using a position sensor, and estimating a position of the mechanical end stop using at least the current maximal displacement. | 12-03-2015 |
20160070114 | PASSIVE DAMPING SOLUTION TO OPTICAL IMAGE STABILIZATION FOR VOICE CONTROL MOTORS - Passive dampers (e.g., a viscoelastic material such as a silicon gel) may be applied at one or more locations within an actuator module along wires suspending a moving component (an optics assembly) from a fixed component (e.g., a base of an actuator module). The passive dampers act to passively dampen the motion of the optics assembly on the XY plane within the actuator module during optical image stabilization (OIS) of the optics assembly when subjected to external excitation or disturbance, and may also provide Z (optical) axis damping and impact protection. Process control and automation manufacturing and assembly methods for an OIS voice coil motor (VCM) actuator module including passive dampers are described, as well as design elements that provide for the integrity and reliability of the passive dampers over the life cycle of the actuator module. | 03-10-2016 |
20160112618 | IMAGE SHAKE CORRECTING DEVICE AND CONTROL METHOD THEREFOR, LENS BARREL, OPTICAL APPARATUS, AND IMAGE PICKUP APPARATUS - An angular velocity sensor detects a shake of an image pickup apparatus and a signal divide unit divides a shake detection signal to output it to each of a first drive amount calculating unit and a second drive amount calculating unit. A first drive amount and a second drive amount are calculated based on the divided shake detection signal to drive each of a first correction lens and a second correction lens. An aberration determination unit changes a limiter used in a drive amount limiting unit based on the first drive amount and the second drive amount so as not to increase the eccentric aberration of an imaging optical system generated by the movement of the two correction lenses. The drive amount limiting unit limits the drive amount based on the limiter set according to the result of the determination for the aberration to correct the image shake while suppressing the eccentric aberration. | 04-21-2016 |
