摘要： Method and system for on-chip processing to obtain an EDOF image combines interferometry and imaging so the two operations do not interfere with one another but, rather, work together to create an in-focus, true color image of a three-dimensional object. This image has no significant artifacts and requires only limited processing. In addition, a coarse depth map is created in the process which may also be helpful in subsequent usage of the acquired image. A CMOS pixel-array sensor includes circuitry to implement processing at the pixel level.

摘要： A method for imaging of an object includes, for each of a plurality of surface-regions of the object, determining a corresponding image-sensor pixel group of a camera illuminated by light propagating from the surface-region via a lens of the camera. The method also includes, after the step of determining and for each surface-region: (i) changing a distance between the object and the lens such that the surface region intersects an in-focus object-plane of the camera and the lens forms an in-focus surface-region image on the corresponding image-sensor pixel group; (ii) capturing, with the corresponding image-sensor pixel group, the in-focus surface-region image of the surface-region; and (iii) combining the in-focus surface-region images, obtained by performing said capturing for each surface-region, to yield an all-in-focus image of the object.
