Directional scaling systems and methods

Abstract

An electronic device may include scaling circuitry to scale input pixel data to a greater resolution. The directional scaling circuitry may include first interpolation circuitry to receive best mode data, including one or more angles corresponding to content of the image and interpolate first pixel values at first pixel positions diagonally offset from input pixel positions of the input pixel databased on the best mode data and input pixel values corresponding to the input pixel positions. The directional scaling circuitry may also include second interpolation circuitry to receive the best mode data and the input pixel values and interpolate second pixel values at second pixel positions horizontally or vertically offset from the input pixel positions based at least in part on the best mode data and the input pixel values.

Description

Background technique

[0001] The present disclosure relates generally to image processing, and more particularly to the analysis of pixel statistics, scaling and / or enhancement of image data for displaying images on electronic displays.

[0002] This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present disclosure, which are described and / or claimed below. This discussion is considered helpful in providing the reader with background information to facilitate a better understanding of various aspects of the disclosure. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.

[0003] Electronic devices typically present visual representations of information, such as text, still images, and / or video, by displaying one or more images (eg, image frames) using one or more electronic displays. For example, such electronic devices may include comp...
