摘要： Digital images are computed using an approach for correcting lens aberration. According to an example embodiment of the present invention, a digital imaging arrangement implements microlenses to direct light to photosensors that detect the light and generate data corresponding to the detected light. The generated data is used to compute an output image, where each output image pixel value corresponds to a selective weighting and summation of a subset of the detected photosensor values. The weighting is a function of characteristics of the imaging arrangement. In some applications, the weighting reduces the contribution of data from photosensors that contribute higher amounts of optical aberration to the corresponding output image pixel.

摘要： Various approaches to imaging involve selecting directional and spatial resolution. According to an example embodiment, images are computed using an imaging arrangement to facilitate selective directional and spatial aspects of the detection and processing of light data. Light passed through a main lens is directed to photosensors via a plurality of microlenses. The separation between the microlenses and photosensors is set to facilitate directional and/or spatial resolution in recorded light data, and facilitating refocusing power and/or image resolution in images computed from the recorded light data. In one implementation, the separation is varied between zero and one focal length of the microlenses to respectively facilitate spatial and directional resolution (with increasing directional resolution, hence refocusing power, as the separation approaches one focal length).

摘要： Image data is processed to facilitate focusing and/or optical correction. According to an example embodiment of the present invention, an imaging arrangement collects light data corresponding to light passing through a particular focal plane. The light data is collected using an approach that facilitates the determination of the direction from which various portions of the light incident upon a portion of the focal plane emanate from. Using this directional information in connection with value of the light as detected by photosensors, an image represented by the light is selectively focused and/or corrected.
