Samsung is launching its new 200-megapixel Isocell HP2 image sensor which aims to give smartphone photographers high resolution and good image quality in challenging conditions. The sensor is expected to be used in the company's flagship Galaxy S23 Ultra phone, which is set to debut in February. The HP2 sensor uses new methods to counteract the problem of small pixels not being able to gather light as well in low-light conditions, such as by gathering light more effectively and boosting high dynamic range (HDR) photos. Samsung is focusing on technology as camera improvements are a prime reason to upgrade phones, and the company's rival Apple is also investing heavily in its cameras.
