【Big chip solution】Image output is as stable as a rock, WPG launches Novatek-based electronic image stabilization (EIS) solution

Steel said

To achieve high-definition and stable output of video images and powerful anti-shake, look to WPG Group's electronic image stabilization (EIS) solution based on Novatek NT98530+SmartSens SC850SL and a gyroscope (GYRO). It has high image quality, low bit rate, and low power consumption, supports a rate of up to 640M pixels/second, and has an AI computing power of up to 2T. The highly integrated SensPro2 is CEVA's latest generation of DSP, which makes the output image stable and not shaken.

On September 12, 2024 , WPG Holdings, a leading semiconductor component distributor dedicated to the Asia Pacific market, announced

Its subsidiary Quan Ding launched an electronic image stabilization (EIS) camera solution based on Novatek NT98530 chip, SmartSens SC850SL image sensor and TDK ICM-42607 IMU (inertial sensor module). ☜

Today, the innovation of imaging technology is driving the development of all industries at an unprecedented speed, especially in the fields of consumer electronics, smart security, autonomous driving and telemedicine. High-definition, stable and low-latency video capture capabilities are becoming an indispensable key technology for building smart life. To meet this market demand, WPG Semiconductor has launched an electronic image stabilization (EIS) camera solution based on Novatek's NT98530 chip, SmartSens' SC850SL image sensor and TDK's ICM-42607 IMU (inertial sensor module).

EIS (Electric Image Stabilization) is a technology that uses the inertial sensor module IMU to obtain changes in camera posture, and then offsets the image shake caused by camera vibration by partially cropping and deforming the original image, so that the output image is stable.

NT98530 is a highly integrated SoC from Novatek Technology, supporting a processing rate of up to 640M pixels/second, and can achieve more than 8 million pixels/60FPS edge computing performance. The integration of the new generation DSP of CEVA SensPro2 inside the SoC, combined with its fully optimized SDK, can ensure that the SoC has sufficient performance to support complex computer vision algorithms and neural network reasoning. In addition, the SoC integrates the ARM Quad Cortex A53 CPU core, a new generation ISP, an H.265/H.264 video compression encoder, a high-performance hardware DLA module, a graphics engine, a dual display controller, an Ethernet GMAC, USB3.0 and USB 2.0 host/device, an audio codec, RTC and SD/SDIO 3.0, which can provide cost-effective edge computing IP camera solutions.

SC850SL是思特威旗下首款Stack的Rolling Shutter产品，采用Stack BSI+RS架构设计大幅提升产品的灵敏度与暗光成像性能，并且搭载思特威第二代近红外感度NIR+技术，使QE（量子效率）显著提升。

In terms of IMU selection, the solution uses the TDK ICM-42607 chip, which combines a 3-axis gyroscope and a 3-axis accelerometer, with a FIFO of up to 2.25KB, which can reduce the traffic on the serial bus interface and allow the system processor to burst read sensor data and then enter low-power mode.

When designing the circuit, the TDK ICM-42607 needs to be placed parallel or perpendicular to the three-axis angle of the Sensor IC. NT98530 can connect to the TDK ICM-42607 via the SPI interface to provide EIS function and perform related setting control and data transmission. Thanks to the excellent performance of these devices, this solution can provide more stable and clear image performance for a variety of camera applications.
