Embodiment Construction

[0033] One or more specific embodiments are described below. In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, decisions specific to many implementations must be made to achieve the developer's specific goals, such as conformance may vary from one implementation to Another implementation-specific system-related and business-related constraint. In addition, it should be understood that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, engineering, and fabrication for those of ordinary skill in the art having the benefit of this disclosure.

Abstract

An electronic device may include scaling circuitry to scale input pixel data to a larger resolution. The directional scaling circuit may include a first interpolation circuit for receiving best mode data comprising one or more angles corresponding to the content of the image and in relation to the input pixel data from the input pixel data. A first pixel value is interpolated at a first pixel position diagonally offset from the input pixel position based on the best mode data and an input pixel value corresponding to the input pixel position. The directional scaling circuit may also include a second interpolation circuit for receiving the best mode data and an input pixel value and at least partially at a second pixel position horizontally or vertically offset from the input pixel position The second pixel value is interpolated based on the best mode data and the input pixel value.

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...
