In an embodiment, a method includes: receiving data signals from a plurality of pixels of an array of pixels; generating a plurality of signal-to-noise ratios by determining signal-to-noise ratios for each respective pixel of the plurality of pixels on the basis of the data signals received from the respective pixel; and filtering the data signals received from each pixel of the plurality of pixels by using an adaptive filter configured on the basis of the plurality of the signal-to-noise ratios to generate filtered data signals.

Filtering device, associated system and method

A method of adjusting a lens may include adjusting the lens at a first focus position, and acquiring a first image of a scene through the lens. The method may further include adjusting the lens at a second focus position, and acquiring a second image of the same scene through the lens. In addition, the method may include producing respective power spectra of the first and second images, and producing a criterion representing the ratio of the power spectra to estimate a focus error of the lens.

Defocus estimation method independent of the scene content and use in an autofocus system

A method is for evaluating a coverage factor of a photon emission cone of a time of flight sensor. The method may include the steps of assigning a reference curve to the sensory providing a photon flux intensity as a function of time of flight; and acquiring a time of flight and a corresponding flux intensity with the sensor. The method may also include reading the intensity provided by the reference curve for the acquired time of flight, and providing an indication of the coverage factor based on the ratio between the acquired intensity and the read intensity.

Method for evaluating position and motion using time of flight detectors

A method for detecting at least one object in an image including a pixel array, by means of an image processing device, including searching out the silhouette of the object in the image only if pixels of the image are at the minimum or maximum level.
