  • Patent number: 8310587
    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.

  • Patent number: 7999851
    Abstract: A method for calibration of an imaging device that includes a sensor and optics for forming an image on the sensor. The method includes making a first image quality measurement, based on an output of the sensor, while imaging a first target at a first distance from the device and varying an offset between the optics and the sensor. A second image quality measurement is made while imaging a second target at a second distance from the device, which is different from the first distance, and varying the offset between the optics and the sensor. A working point of the optics is set relative to the sensor responsively to the first and second image quality measurements.

  • Publication number: 20070236574
    Abstract: A method for producing a camera, which includes objective optics for forming an image on an electronic image sensor and a digital filter for filtering an output of the image sensor. The method includes defining a maximum permissible value of a noise gain and determining one or more aberrations due to the objective optics. Coefficients of the digital filter are calculated so as to compensate for the one or more aberrations while preventing the noise gain of the digital filter from exceeding the maximum permissible value. The output of the image sensor is filtered using the computed coefficients so as to generate an enhanced output image.
