Abstract
One embodiment of a display system includes a control module that controls an adjustable aperture based on a calculated aperture setting and that applies a calculated gain setting to a set of frame data to define a modified set of frame data, an image analysis module that calculates a gain setting and an aperture setting for said set of frame data and forwards said calculated gain setting and said aperture setting to said control module, and a frame data buffer that stores said set of frame data during calculation by said image analysis module.
Claims20
A display system, comprising:
- a control module that controls an adjustable aperture based on a calculated aperture setting and that applies a calculated gain setting to a set of frame data to define a modified set of frame data;
- an image analysis module that calculates a gain setting and an aperture setting for said set of frame data and forwards said calculated gain setting and said aperture setting to said control module;
- and
- a frame data buffer that stores said set of frame data during calculation by said image analysis module.
A method of controlling a contrast ratio of an image, comprising:
- receiving an image frame data;
- routing said image frame data to both an image analysis module and to a frame buffer;
- conducting an image analysis of said image frame data by said image analysis module to calculate a gain setting;
- and
- applying said gain setting to said image frame data of said frame buffer to control a contrast ratio of said image frame data.
An image projection apparatus, comprising:
- an image modulator that outputs a viewable image having a controlled contrast ratio;
- a set of machine operable instructions that calculates a gain setting and applies said gain setting to a set of frame data to define a modified set of frame data, and that transmits said modified set of frame data to said modulator to produce said viewable image;
- and
- an electronic buffer that stores said set of frame data during calculation of said gain setting by said machine operable instructions, wherein said electronic buffer sends said set of frame data to said set of machine operable instructions after calculation of said gain setting.
