摘要： An image sensor is formed with shifts among the optical parts of the sensor and the photosensitive parts of the sensor. The optical parts of the sensor may include a color filter array and/or microlenses. The photosensitive part may include any photoreceptors such as a CMOS image sensor. The shifts allow images to be formed even when the light received at a given pixel location varies in angle of incidence as a function of pixel location within the array. The relative shifts among the pixel components may be, for example, plus or minus some fraction of the pixel pitch. The shift may be variable across the array or may be constant across the array and may be deterministically determined.

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： 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 method for controlling the frequency dependence of insertion loss in an etalon-lens-fiber (ELF) optical assembly comprises defining target frequencies and insertion loss objectives therefor and adjusting the optical path length between pairs of the etalon, lens and fiber components until insertion loss objectives are achieved. Insertion loss objectives include insertion loss and insertion loss ripple objectives. The method allows for control of the frequency dependence of insertion loss and insertion loss ripple without introducing additional components, such as spectral filters, into the system.
