Soundscape evaluation and integrated humanist ecology of audiovisual sense in Hangzhou Gongshu section of the Beijing-Hangzhou Grand Canal

Located at the end of the Beijing-Hangzhou Canal,Hangzhou has a historical and cultural heritage with an abundance of acoustic and visual landscape.The paper introduces the concept of“soundscape”into the canal landscape design,and analyzes its characteristics through documentary analysis,questionnaire method,soundscape walk method,grid method and statistical analysis method.Besides,GIS is also used to present the analysis in a visualized way.The study adopt the increase,decrease and protect design methods which are commonly used in soundscape and the landscape combination methods derived from the classic landscape rules.Eventually,the design is performed in a targeted manner from the perspective of the integrated design of vision and soundscape,offering a optimum proposal and construction strategy.It is hoped that it can promote the design of the integrated acoustic-visual environment of the canal so as to improve the overall spatial environment quality of the urban canal.

CMOS vision sensor with fully digital image process integrated into low power 1/8-inch chip

A digital still camera image processing system on a chip, different from the video camera system, is pre- sented for mobile phone to reduce the power consumption and size. A new color interpolation algorithm is proposed to enhance the image quality. The system can also process fixed patten noise （FPN） reduction, color correction, gamma correction, RGB/YUV space transfer, etc. The chip is controlled by sensor regis- ters by inter-integrated circuit （I2C） interface. The voltage for both the front-end analog and the pad cir- cuits is 2.8 V, and the volatge for the image signal processing is 1.8 V. The chip running under the external 13.5-MHz clock has a video data rate of 30 frames/s and the measured power dissipation is about 75 roW.
