US 2018/0027216 A1 · IMAGER SYSTEM WITH MEDIAN FILTER AND METHOD THEREOF

Abstract

An imaging system configured to display a captured image on a display having a lower dynamic range than the imaging system is provided, wherein the imaging system includes a high dynamic range imager configured to capture at least one high dynamic range image, and a processing device communicatively connected to the high dynamic range imager, wherein the processing device is configured to reduce color speckles caused by errant interpolated pixel values and reduce occurrence of errant values of alternate color while maintaining at least one of sharpness detail, edge detail, and generate smoothing color rendering in a displayed image.

Dependent claims

An imaging system configured to display a captured image on a display having a lower dynamic range than the imaging system, the imaging system comprising:

a high dynamic range imager configured to capture at least one high dynamic range image;
and
a processing device communicatively connected to said high dynamic range imager, wherein said processing device is configured to rank each element of an array with respect to an ordering criterion and select a median element, where the median element is a function of a ratio of a non-reference color component of a pixel to a reference color component of the pixel, wherein said ordering criterion comprises a discrete ranking value assigned to every element.

Dependencies are inferred from the claim text.
