In recent years, smartphone photography has made remarkable progress. On the one hand, it benefits from multi-lens technology, on the other hand, it comes from the upgrade of CIS image sensor. On P30 series mobile phones, Huawei also adopted RYYB sensor to increase the amount of light, so that night scenes can be photographed in by going up one flight of stairs. There are two mainstream technologies for CIS sensors: FSI front-illuminated and BSI back-illuminated. Recently, Stevie Electronics announced the introduction of DSI pixel sensor technology, which can significantly improve the performance of the sensor, and its sensitivity is twice that of FSI sensor, especially suitable for applications that need to shoot ultra-clear video in low light environment.

According to the data of official website, SmartSens Technology is a high-performance CMOS image sensor chip design company, which was founded on 20 1 1 and has the world-leading R&D teams in Silicon Valley of the United States and Shanghai, China. SmartSens focuses on providing future-oriented and world-leading CMOS image sensor chip products, and is the first company in the world to launch a globally exposed CIS chip based on voltage domain architecture and BSI process. At present, SmartSens is in a leading position in the field of video surveillance, and its products involve security monitoring, vehicle images, machine vision and consumer electronic products (sports cameras, drones, sweeping robots, smart home cameras) and other application fields.

It is worth mentioning that at this year's ISSCC international conference, Entway became the first image sensor design company selected in China since the founding of the conference. His paper "Stacked Global Shutter CMOS Imager with SC-type mixed GS pixels and self-inflection point calibration single frame HDR and on-chip binarization algorithm for intelligent vision applications" attended the ISSCC conference.

At ISC West 20 19, Stevie Electronics announced the launch of DSI pixel sensor technology, which is the latest next-generation sensor technology developed by the company. Compared with the previous generation technology, it can provide better performance, faster time to market and higher cost performance, and its performance is better than that of FSI and BSI sensors.

According to the company, DSI pixel sensor technology is equipped with the advanced sensor architecture of Entway Electronics, which can significantly improve the technical indicators of the sensor. Sensitivity is twice that of FSI sensor, and dark current is twice as low. It is also superior to FSI and BSI sensors in SNR 1 and reading noise.

DSI pixel sensor technology is suitable for all kinds of applications that need high-definition shooting, as well as all-weather applications that need to perform key tasks in bad lighting environment, such as video surveillance, AIoT, smart home and so on.

However, Entway Electronic Technology Co., Ltd. did not mention the information about when DSI pixel sensor products will be launched.
