Samsung has announced 50MP camera sensor with faster autofocus



Samsung has revealed a new 50 megapixel image sensor dubbed ISOCELL GN1. It's Samsung's first sensor to feature both dual-pixel autofocus and Tetracell pixel-binning, which the firm claims will deliver a mix of good output and low-light picture clarity. The pixel size is 1.2μm, comparable to what you will see on a traditional phone camera sensor than the high-resolution sensors that have been more common in the past year. The main rival is Sony's latest IMX689 camera, used on phones including the Oppo Find X2 Pro, which has 48 megapixels at 1.22μm. Samsung's sensor will take 12.5-megapixel photos with four pixels attached to one by default.

Addition of dual-pixel phase-detection autofocus is noteworthy because Samsung has had a recent high-profile failure in this area. The Galaxy S20 Ultra, which used a 108-megapixel sensor without dual-pixel processing, suffered from weak autofocus performance; Samsung said it would repair it, but we haven't been able to check for progress yet. In any case, the combination of increased resolution and fast autofocus speed is clearly Samsung 's priority over ISOCELL GN1. The company claims the sensor went into mass production this month, and it shouldn't be that long until it's on the phone.
