HiperVis
Overview
As an image sensor technology specialized for automotive applications, we are researching and developing technologies that include various imaging technologies such as HDR and LFM, which are essential in the automotive market, as well as temperature/humidity resistance, shock resistance, self-diagnostic functions, and high-speed transmission and reception capabilities and low-power characteristics that will be required for future high-level autonomous driving functions.
HiperVis Features
- Image sensors with HiperVis technology can be used in a variety of Advanced Driver Assistance System (ADAS) applications, including rearview cameras, SVM cameras, interior monitoring cameras, wing-mirror cameras, and front-facing cameras.
- - Pixel design techniques to minimize random noise and random telegraph signal (RTS) noise and improve signal to noise ratio (SNR).
- - Doping optimization techniques to improve full well capacitance while maintaining charge transfer efficiency
- - Source follower buried channel technology to reduce read noise
- - Optimal pixel design and process optimization techniques to enhance charge transfer even under small FD capacitance conditions to improve sensitivity
- - Deep Trench Isolation technology to minimize crosstalk between adjacent pixels
- - Pixel design and process optimization techniques to ensure high full well capacitance (FWC) for low conversion gain (LCG) and HDR characteristics
- - Backside Scattering Technology (BST) process adaptation and optimization techniques for increased sensitivity in the infrared (IR) quantum efficiency (QE) 850-940 nm band
- PIXELPLUS' HiperDR technology provides image quality optimized for automotive applications by simultaneously delivering 120dB of High Dynamic Range and LED Flicker Mitigation, even in automotive environments with varying light conditions, such as day and night.
- - 120dB High Dynamic Range imaging with Dual Conversion Gain (DCG) and Multi exposure technology
- - Optimized HDR Combine Reconstruction technology for the best possible image quality
- - High-precision/fast analog digital converter (ADC) technology provides multi-imaging capability for HDR technology implementation
- PIXELPLUS' HiperCat technology enables optimized image recognition for driver monitoring systems by recognizing human faces and pupils in dark rooms, even when driving at night.
- PIXELPLUS has specialized sensors and ISP technology for the Surround View Monitoring system. This enables you to develop SVM solutions that are competitively priced, yet have excellent image quality and high reliability.
- PIXELPLUS has acquired sensor and ISP technologies that are especially specialized for Surround View Monitoring systems. This enables us to develop SVM solutions with excellent image quality and high reliability at a competitive price.
- By applying CNA (Color Noise Adaptation) technology, which was developed and patented in-house, we have developed a new concept image sensor that can implement color information and infrared information on one screen by overcoming the limitation that existing image sensors have to output RGB color images and infrared images separately.
This image sensor is characterized by enabling the camera to be configured with only an ISP chip for general RGB color image processing without a separate ISP chip for infrared image processing.
