Optimization of alignment between elements in an image sensor

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.
