The weather, here in the Northern hemisphere at least, is starting
to get bright and sunny. This means that leaving the house early
puts the sun squarely ahead of me on my walk to work. To combat
this, I go with the conventional solution that is some sunglasses.
Now, I go to play a podcast or
some music, and, dammit! Can't see
the screen. So, given how sophisticated facial recognition
algorithms are, detecting sunglasses should be easy. So let's do
that, and upon detecting sunglasses, ramp up the phone
brightness.

"True Tone, which is on by default, uses sensors to adjust the color and intensity of your display to match the ambient light, so that images appear more natural. [a1, May 05 2022]

If the phone is outside and the sun is shining, then the screen will already be at maximum brightness. |
|
| |
If the user is wearing sunglasses inside where the screen brightness is less than maximum, then there would be a use for this technology, but I would suggest that a better solution would be for the phone not to increase its brightness but instead for the user to realise they are wearing sunglasses indoors and to take them off. |
|
| |
Unless of course they are wearing sunglass lights in which case the lights will trigger the brightness sensor to make the screen to go to maximum brightness |
|
| |
Not necessarily. If the phone is in the shadow of your head,
for instance, it might be auto adjusted to a lower
brightness. |
|
| |
Might be best to use BOTH cameras (front & back, I mean...
phones these days with their 17 different cameras...); front
looks at you face to see sunnies etc, back looks at the ground
to see the brightness of the other things in your field of view
(overall FOV brightness determines iris aperture, or
something...). |
|
| |
The point is, that even though phones do auto screen
brightness, that's a separate thing to when you're wearing
sunglasses. Shadows, inside, whatever. With sunglasses,
brightness should be max. |
|
| |
Right so the whole outdoors schtick was a red herring (even on a couldy day or int he shadow of [21]'s head the luminousitey of the outdoors is a lot brighter than any super bright interior). |
|
| |
But the whole sunglasses indoors thing is a whole other can of flies. |
|
| |
//best to use BOTH cameras// |

As far as I know, they don't use cameras for light level sensing.
It's much more sensible to use a sensor that needs no optical
elements or multiple pixels for spatial resolution. All you need
is light intensity. For that they use ambient light sensors, just
photoresistors/diodes. Thinking about it, they could also
incorporate some spectral information, even just basic RGB,
you could use that to tune the screen color balance. |

Poc, you meantion sunglasses indoors but this is actually
a good point to raise here. Anyone who's ever used
transition lenses and had to wait several minutes upon
entering a building for the darkened lenses to go clear
again would benefit from this. |

"Did you go out to lunch yet Jeff?"
"No"
"Liar" |

I have a colleague who comes in on bright, cold winter
mornings with dark lenses that are rapidly accumulating
condensation "My glasses are blinding me in two independent
ways!" |
