摘要： The embodiments herein are generally directed to using a current-mode CBC circuit to maintain a voltage bias setting at a receiver when performing capacitive sensing. To do so, the CBC circuit may compensate for the change in voltage at a receiver by providing a current at the input of the receiver. Instead of using a passive CBC capacitor for each receiver, the input device may use a single CBC capacitor and a plurality of current mirrors to source and sink the current required to correct the input voltage at a plurality of receivers. As a result, the current-mode CBC circuit includes only one passive capacitor (or bank of capacitors) and a plurality of current mirrors which may provide space and cost benefits relative to a CBC circuit that uses a passive capacitor (or bank of capacitors) for each receiver channel.

摘要： Embodiments of the present invention generally provide a method for processing an image. The method includes receiving a plurality of input pixel values associated with a video frame and determining that a first portion of pixel values included in the plurality of input pixel values is within a first set of excluded values. The method further includes dithering the first portion of pixel values to generate a first plurality of dithered values. Each dithered value included in the first plurality of dithered values is not within the first set of excluded values. Additionally, a first average pixel value associated with the plurality of input pixel values is substantially similar to a second average pixel value associated with both the first plurality of dithered values and a plurality of pixel values that are spatially proximate to the first plurality of dithered values.
