Variable scaling ratio systems and methods

Abstract:

An electronic device may include an electronic display to display an image based on scaled image data and variable scaling circuitry to generate the scaled image data. Generating the scaled image data may include receiving input pixel values in a first resolution and determining multiple tap point locations based on a scaling ratio to be applied to the input pixel values. Generating the scaled image data may also include determining weighting coefficients based on a scaling curve and the tap point locations, and weighting the input pixel values based on the weighting coefficients. The variable scaling circuitry may generate the scaled image data at a second resolution based on the aggregation of the weighted input pixel values.
