Abstract
In some embodiments, a method, system, or computer-readable storage device including instructions for reducing the blue light component of displayed video can include one or more of the following features: receiving, at a set-top box, a video signal having a white color balance, the white color balance including a red component value. The set-top box can determine that the current time is after a threshold night value and before a threshold morning value and, based on that, adjust the white color balance of the video signal to increase the red component value. The set-top box can then transmit the video signal with the adjusted white color balance to a display device.
Claims23
A method for reducing a blue light component of displayed video, comprising:
- receiving, at a set-top box, a video signal having a white color balance, the white color balance including a red component value;
- adjusting, by the set-top box, the white color balance of the video signal by:
- when a current time reaches a predefined period of time before a threshold night value, gradually adjusting the white color balance of the video signal to increase the red component value to a set value incrementally over the predefined period of time,
- when the current time is after the threshold night value and before the predefined period of time before a threshold morning value, adjusting the white color balance of the video signal to maintain the red component value at the set value, and
- when the current time reaches the predefined period of time before the threshold morning value, gradually adjusting the white color balance of the video signal to decrease the red component value from the set value incrementally over the predefined period of time;
- and
- transmitting, from the set-top box, the video signal with the adjusted white color balance to a display device.
(canceled)
A system for reducing a blue light component of displayed video, comprising:
- a processor;
- and
- a memory, the memory containing instructions that, when executed by the processor, cause the processor to:
- receive a video signal having a white color balance, the white color balance including a red component value;
- adjust the white color balance of the video signal by:
- when a current time reaches a predefined period of time before a threshold night value, gradually adjust the white color balance of the video signal to increase the red component value to a set value incrementally over the predefined period of time,
- when the current time is after the threshold night value and before the predefined period of time before a threshold morning value, adjust the white color balance of the video signal to maintain the red component value at the set value, and
- when the current time reaches the predefined period of time before the threshold morning value, gradually adjust the white color balance of the video signal to decrease the red component value from the set value incrementally over the predefined period of time;
- and
- transmit the video signal with the adjusted white color balance to a display device.

A machine-readable storage device having stored thereon instructions for reducing the blue light component of displayed video, the instructions causing one or more processors to perform operations, including:
- receiving a video signal having a white color balance, the white color balance including a red component value;
- adjusting the white color balance of the video signal by:
- when a current time reaches a predefined period of time before a threshold night value, gradually adjusting the white color balance of the video signal to increase the red component value to a set value incrementally over the predefined period of time,
- when the current time is after the threshold night value and before the predefined period of time before a threshold morning value, adjusting the white color balance of the video signal to maintain the red component value at the set value, and
- when the current time reaches the predefined period of time before the threshold morning value, gradually adjusting the white color balance of the video signal to decrease the red component value from the set value incrementally over the predefined period of time;
- and
- transmitting the video signal with the adjusted white color balance to a display device.
