A CMOS image sensor with pseudorandom pixel placement for clear imaging

金沢大学理工研究域電子情報学系The picture element (pixel) in conventional image sensors, such as CCD or CMOS imager, are placed in the form of a lattice for ease of implementation. Lattice placement of pixels intrinsically has directional dependency on the clarity of image representation; in other words, the image clarity is significantly dependent on the directions of the objects in the image, such as lines. For example, horizontal lines are perfectly represented by lattice pixels, while slanted lines have jagged edges. In this paper, we propose a pseudorandom pixel placement architecture for clear imaging with solving the directional dependency problems. We also discuss our evaluation of its characteristics based on the designed layout of CMOS image sensor with pseudorandom pixel placement, as well as its implementation. ©2009 IEEE

Poster: Power spectrum analysis of reflected waves with ultrasonic sensors indicates "what the target is"

We consider that ultrasonic waves can be used not only for measuring the distance to a target but also for comprehending what the target is simultaneously. We assumed that the physical characteristics of a target object (especially, surface information) are embedded in the power spectrum structure of the ultrasonic waves reflected from the target. The results of our investigation to analyze the characteristics of the power spectrum structure of waves reflected from various kinds of target materials showed whether target objects are soft and deformable or hard and undeformable

RoboCup for science and engineering education: a case of the future University - Hakodate

金沢大学大学院自然科学研究科情報システム金沢大学工学部A newly starting university in Japan, FUnHakodate, is described. The concepts of FUnHakodate is to gather the various areas concerned with the computers, and one of the most important themes is learning through projects. One such project concerns the development of RoboCup

Fast square-area detection algorithm using automata for VLSI implementation

金沢大学大学院自然科学研究科情報システム金沢大学工学部Conventional image sensors, including CCD sensors and smart sensors are considered for just acquiring the image as the matrix of dots, not for recognizing the meaning of image. In this paper, we propose a novel real-time algorithm to detect the square area in an object using the structure of node automata, and discuss its implementation as a CMOS image sensor, where the pixels and the node automata are integrated in one chip. We also discuss the search algorithm of their position in the pixel plain using area dividing methodology
