Howe releases OV50K40 sensor: the first LOFIC technology, breaking through the dynamic range and approaching the human eye!

Domestic manufacturer Howe recently released a new CMOS sensor OV50K40. This sensor is the world’s first smartphone image sensor to apply TheiaCel technology, and its unique design enables a dynamic range close to human visual levels. This breakthrough means that users can obtain more realistic and clear images during shooting, bringing higher image quality performance to mobile photography. Howe has taken a solid step on the road of continuous technological innovation and contributed significantly to the development of the field of smartphone photography. The launch of this new sensor will further promote the

OV50K40 sensor has a native resolution of 50 million pixels and uses a 1/1.3-inch large base area, each pixel The area reaches 1.2 microns. In addition, it also supports pixel four-in-one output, which combines four pixels into one to output a 12.5-megapixel image, resulting in more powerful photosensitivity.

The sensor’s frame rate support is 120 fps and 60 fps (HDR), enabling full 50-megapixel Bayer output, premium 8K video, and 2x crop zoom capabilities.

One of the most noteworthy features is its support for Quad Phase Detection (QPD) functionality, which means it is capable of 2x2 Phase Detection Autofocus (PDAF) across the entire sensor's image array, or 2x2 ocl.

However, the most compelling feature of the OV50K40 sensor is its use of Lateral Overflow Integrating Capacitor (LOFIC) technology. Its principle is to place a high-density capacitor at each photodiode position of the mobile phone sensor to collect photoelectrons that may overflow due to excessive illumination.

When a photodiode converts more photoelectrons than its capacity, the excess photoelectrons will flow into an adjacent capacitor without being lost due to overexposure. In this way, the highlight information in the shooting scene can be better captured and retained by the sensor, making the output of the photo closer to the real-world light and shadow scene and achieving ultra-high dynamic range.

High dynamic range is usually one of the reasons for the excellent look and texture of professional SLR camera photos, because it can restore the colors, light and shadow and other effects seen by the human eye as much as possible . The launch of the OV50K40 sensor has enabled mobile phone photography to be comparable to SLR cameras.

Editor’s comment: The release of the OV50K40 sensor marks an innovative breakthrough for domestic manufacturers in the field of smartphones. This sensor using TheiaCel technology and LOFIC technology not only has excellent resolution and light-sensing capabilities, but also can present a dynamic range close to the level of the human eye. Its emergence will further promote the development of mobile photography, allowing users to easily take stunning photos and videos.
