Ambient light sensing technique

A system, comprising:

• a display panel;
• an ambient light sensor configured to receive ambient light;
• and
• a processor configured to provide image data to be displayed by the display panel, wherein the processor is configured to provide adjusted image data as the image data when the ambient light indicates the presence of a particular lighting condition.

A device, comprising:

• an ambient light sensor configured to receive light;
• and
• a processor configured to:
• measure intensity levels of different components of the received light;
• generating a first set of weighted measured intensity levels of the different components using the measured intensity levels and a first set of weighting factors;
• calculate a first luminance value related to the first set of weighted measured intensity levels;
• and
• control the brightness level of a light source based on the first luminance value when the first luminance is above an upper threshold value.
