Abstract
Imaging apparatus includes an image sensor, which is adapted to generate an input image in response to optical radiation that is incident thereon. A processing engine is configured to apply a digital filter to the input image so as to generate a filtered image, the digital filter having a kernel, which has a kernel width that is greater than five pixels. An optical assembly is arranged to focus the optical radiation onto the image sensor with a point spread function (PSF) such that no more than a first threshold percentage of energy emitted from a point object and focused by the optical assembly falls within a first region of the image sensor having a first width that is five times the pitch of the image sensor, while at least a second threshold percentage of the energy emitted from the point object and focused by the optical assembly falls within a second region, which contains the first region and has a second width corresponding to the kernel width.
