Patent ID: 8310587

Claim:
An imaging apparatus, comprising: an image sensor, characterized by a pitch, which is adapted to generate an input image in response to optical radiation that is incident on the image sensor; a processing engine, which 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; and an optical assembly, which is arranged to focus the optical radiation onto the image sensor spread function (PSF) such that no more threshold percentage of energy emitted object and focused by the optical assembly first region of the image sensor having that is five times the pitch of the image with a point than a first from a point falls within a a first width 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.
