Samsung: Upcoming ISOCELL Will Drastically Improve Video Quality

Samsung has revealed its plans to bring big improvements for the next-gen ISOCELL camera sensors. Which specifically targeted at the video quality. Nowadays, smartphone cameras have become more important due to the growth of social media platforms. Everyone wants the best quality videos for their content in order to get plentiful views and share. However, it is more complex to shoot a video than taking a picture. To add, a video shoot requires the capture of 30 frames each second rather than one-single frame.

Multi-frame and multi-exposure (HDR) processing vastly improves still images by capturing at least two frames (low exposure and high exposure) and merging them for greater dynamic range. However, that is extremely difficult to achieve with videos because the camera must capture at least 60 frames per second for a 30fps video. This places a massive load on the camera sensor, ISP, and memory, resulting in increased power consumption and temperature.

ISOCELL sensor with enhanced light sensitivity

Samsung intends to enhance video quality by enhancing light sensitivity, luminance range, dynamic range, and depth sensing. It created an innovative high-refractive nano-structure for the optical wall between pixel color filters. It reinforces the light from adjacent pixels to extreme levels. It’s called Nano-Photonics Color Routing by the South Korean company, and it’ll be available in ISOCELL cameras in 2024.

Sensor for enhancing the dynamic range of video without consuming high power

Samsung intends to launch smartphone camera sensors with in-sensor, single-exposure HDR technology to improve the dynamic range of videos. The ISOCELL HP3 sensor from Samsung has two readouts for 12-bit HDR (high gain for details in the dark and low gain for details in the bright regions). However, the company’s efforts are not limited to this range. They intend to release camera sensors with 16-bit HDR for much greater dynamic range in videos.

iToF sensors for improved portrait videos (background blur)

iToF (Time of Flight) depth sensors with an integrated ISP are being used to improve the quality of portrait videos. Since the whole depth processing is done on the sensor itself, the phone consumes less power and does not overheat as much. Such sensors improve the quality of portrait videos, especially in low-light situations, with narrower objects, and with repeated patterns.

With these improvements, Samsung will definitely step ahead in terms of the quality of still images and videos on smartphones. All of these technologies will debut sometime in 2023 or 2024. These sensors are expected to be used in the Galaxy S24 and Galaxy S25.
