Abstract
Various embodiments for compensating for user view angle of a display device are presented. The viewing angle of a user may be determined using sensors. Based on the viewing angle, the attenuation of the output of the display device may be determined. Compensation mode for the display output may be determined. The compensation mode may adjust the output of the display to compensate for the display attenuation allowing an improved image quality at large viewing angles.

(canceled)
A method for correction of images displayed by a display device, the method comprising:
- detecting, using a signal from one or more sensors for observing an environment proximate to the display device, a set of users in a set of positions relative to the display device;
- computing an effective viewing angle between the display device and the set of users in accordance with the set of positions relative to the display device;
- detecting, according to the one or more sensors, an ambient condition of the environment proximate to the display device;
- and
- adjusting image display settings, responsive to detecting the set of users and responsive to detecting the ambient condition, to modify an output image displayed by the display device to compensate for attenuation of output of the display device when viewed in the ambient condition of the environment proximate to the display device from the effective viewing angle, wherein the adjusting is in accordance with expected attenuation data for the display device determined using a data file associated with the display device.
A television receiver for correction of images displayed by a display device, the television receiver comprising:
- one or more processors;
- one or more sensors for observing an environment proximate to the display device, wherein the one or more sensors are communicatively coupled with the one or more processors;
- and
- a non-transitory memory communicatively coupled with and readable by the one or more processors and having stored therein processor-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including:
- detecting, using a signal from the one or more sensors, a set of users in a set of positions relative to the display device;
- computing an effective viewing angle between the display device and the set of users in accordance with the set of positions relative to the display device;
- detecting, according to the one or more sensors, an ambient condition of the environment proximate to the display device;
- and
- adjusting image display settings, responsive to detecting the set of users and responsive to detecting the ambient condition, to modify an output image displayed by the display device to compensate for attenuation of output of the display device when viewed in the ambient condition of the environment proximate to the display device from the effective viewing angle, wherein the adjusting is in accordance with expected attenuation data for the display device determined using a data file associated with the display device.
