Problems solved by technology

However, brightness increases in electronic displays may still be limited by the maximum brightness of their light sources (e.g., LED backlights or OLED display pixels)
In addition, increasing the brightness of its display pixels can increase the power consumption caused by the operation of electronic displays

Embodiment Construction

[0030] 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.

[0031] To facilitate communication of information, electronic devices typically present a visual representation of that information via one or more...

Abstract

The invention discloses an electronic device (10). The electronic device (10) may include a display pipeline (36) to be coupled between an image data source (38) and a display panel (12). The displaypipeline (36) may include pixel contrast control processing circuitry (52) programmed to determine pixel statistics (60) indicative of an image frame based at least in part on image data that indicates an initial target luminance of a corresponding display pixel implemented on the display panel (12). The pixel contrast control circuitry (52) may also apply a set of local tone maps (64) to determine modified image data that indicates a modified target luminance. The display pipeline (36) may also include a pixel contrast control controller (62) coupled to the pixel contrast control processing circuitry (52). The pixel contrast control controller (62) may be programmed to execute firmware instructions to determine local tone maps to be applied during the next image frame based at least in part on the pixels statistics determined by the pixel contrast control processing circuitry (52).

Description

Background technique [0001] This disclosure relates generally to electronic displays and, more particularly, to processing image data to be used to display 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 computers, mobile phones, portable media devices, tab...
