Embodiment Construction
[0030]FIG. 1 is a block diagram of a multi-aperture, shared sensor imaging system 100 according to one embodiment of the invention. The imaging system may be part of a digital camera or integrated in a mobile phone, a webcam, a biometric sensor, image scanner or any other multimedia device requiring image-capturing functionality. The system depicted in FIG. 1 includes imaging optics 110 (e.g., a lens and / or mirror system), a multi-aperture system 120 and an image sensor 130. The imaging optics 110 images objects 150 from a scene onto the image sensor. In FIG. 1, the object 150 is in focus, so that the corresponding image 160 is located at the plane of the sensor 130. As described below, this will not always be the case. Objects that are located at other depths will be out of focus at the image sensor 130.
[0031]The multi-aperture system 120 includes at least two apertures, shown in FIG. 1 as apertures 122 and 124. In this example, aperture 122 is the aperture that limits the propagat...
