Apple has removed the ultra-wide-angle from its iPad Pro and replaced it with a new sensor that doesn’t take a photo. But what is it for?

Presented at the beginning of May, the new iPad Pro 2024 stood out for its Oled screen, its physical resistance, but also its Apple M4 chip engraved in 3 nm. And Apple has also reworked its design, rotating its front camera block by 90° to find it on the right side of the device. We can of course feel the evolution of the use of this high-end iPad. It is intended to be used in landscape mode, plugged into a keyboard.

At the back too, Apple has revised its sensor configuration. No gain, but loss. The ultra-wide-angle sensor is removed. The wide-angle sensor remains (12 Mpx, f/1.8, 26 mm) alongside a LiDar scanner, a microphone, an LED flash and a mysterious new sensor.

An ambient sensor? To do what ?

This is an ambient light sensor. But usually this one is placed at the front you might say. Its purpose is to adjust the screen brightness according to the ambient lighting. Why did Apple also put one on the back of its tablet?

Apple’s idea is to improve the quality of the rear camera thanks to this ambient sensor. It’s him who brings the new True Tone flash “adaptive” to the iPad Pro M4. This element detects ambient light conditions to facilitate the scanning of documents by removing shadows and modifying the colorimetry of photos, all with the help of artificial intelligence.
