Google has launched an replace that fixes the auto white stability subject on the Pixel 4 units that some customers had delivered to mild final month. The repair is a part of the November safety patch that’s now rolling out to all Pixel units, though the digital camera repair is just for the most recent fashions.
Just a few days in the past, a reddit consumer delivered to consideration the problem with the Pixel four auto white stability, which had a bent to appropriate sturdy, deliberate colours. When taking pictures an image in a room that solely has a purple mild supply (a Philips Hue LED bulb set to shiny purple), the cellphone turned the room to yellow as an alternative of purple. This subject wasn’t seen on different telephones that captured the colour precisely.
The problem was corroborated by Android Police editor Ryne Hager, who shot an image of a crimson cinema curtain, which regarded a really mild shade of pink after the Pixel four digital camera was carried out processing the picture.

The problem appears to be all the way down to the brand new machine studying primarily based auto white stability algorithm that Google launched with the Pixel four, which as an alternative of processing the picture the best way it’s tries to appropriate it to what it ought to be. Google demoed this on stage through the Pixel four launch occasion, the place the cellphone corrects snow that appears blue as a consequence of mild from the sky to white.
Nonetheless, machine studying is barely nearly as good as the info fed to it and is sure to journey up in the end. When proven a very purple room, the ML system probably had no prior data of how one can cope with the state of affairs and did its finest to take away the purple forged, which left the picture with the opposite two main colours, blue and inexperienced, which collectively produced the yellow picture.
After the most recent replace, the problem is fastened and that the digital camera now appropriately renders a purple room as purple.
It is price remembering although that the system should not be bullet-proof and may nonetheless be tripped in excessive situations that the machine studying algorithm hasn’t had any coaching for.
