Abstract
A thin camera having sub-pixel resolution includes an array of micro-cameras. Each micro-camera includes a lens, a plurality of sensors of size p, and a plurality of macro-pixels of size d having a feature of size q. The feature size q smaller than p and provides a resolution for the micro-camera greater than p. The smallest feature in the micro-cameras determines the resolution of the thin camera. Each macro-pixel may have any array of m features of size q, where q=d/m. Additional micro-cameras may be included to increase power.
Claims24
An imaging system comprising:
- an array of lenses;
- a plurality of sensors for each lens, each sensor having a single detection element of size PxPy, with the center-to-center spacing of the detection elements being dx in the x-direction and dy in the y-direction, the plurality of sensors being adjacent to an image plane of a corresponding lens;
- and
- a plurality of macro-pixels of size dxdy, each macro-pixel corresponding to a sensor and being between the corresponding lens and the sensor, each macro-pixel having mxmy micro-pixels, each micro-pixel being of size dx/mx*dy/my and having one of a high and a low transmittance function,
- wherein light transmitted through each lens and directed towards a sensor will impinge on the sensor after multiplication by the transmittance of the macro-pixel, and
- wherein the imaging system has a resolution in the image plane of greater than 1/px in the x-direction or 1/py in the y-direction.
