The present disclosure is directed to a process to partially or fully suppress, or limit, pixel coloration errors. These pixel coloration errors, represented by small noise values, can be introduced during signal processing of high dynamic range (HDR) video signals. Converting visual content to a half precision floating point representation, for example, FP16, can introduce small amounts of signal noise due to value rounding. The noise can be multiplied and accumulated during HDR signal processing resulting in visual artifacts and degraded image quality. The disclosure can detect these noise amounts in pixel color component values, and suppress, or partially suppress, the noise to prevent the noise from accumulating during subsequent HDR signal processing.

Suppress pixel coloration errors in HDR video systems

A method includes receiving by a capacitive touch screen an object code pattern being associated with an object, the object code pattern including at least one conductive part, so that, upon receiving, electric field changes within an area of the capacitive touch screen that interacts with the at least one conductive part. The method further includes detecting the changes in the electric field to produce a virtual object code including an identifier code relating to the object, recognizing the object by comparing the identifier code to a list of identifier codes, providing application data based on the object, and performing using the capacitive touch screen at least one application based on the application data. In addition, a system, an apparatus and a computer program related to the method are presented.
