CMOS image sensor with pseudorandom pixel placement for jaggy elimination
The pixels in the conventional image sensors are placed at lattice positions, and this causes the jaggies at the edge of the slant line we perceive, which is hard to resolve by pixel size reduction. The author has been proposing the method of reducing the jaggies effect by arranging the photo diode at pseudorandom positions, with keeping the lattice arrangement of pixel boundaries that are comp...
متن کاملCMOS image sensor with pseudorandom pixel Placement
The picture element (pixel) in conventional image sensors are placed in the form of a lattice for ease of implementation. Lattice placement of pixels intrinsically has directional singularity on the clarity of image representation, and the clarity is significantly dependent on the directions of the objects in the image. For example, horizontal lines are perfectly represented, while slanted line...
متن کاملPaper Accuracy Evaluation on Area Measurement using Pseudorandom Pixel Placement for Low Resolution Images
Conventional imaging systems have the pixels that are arranged in the regular lattice positions, or lattice pixel placement (LPP). LPP is employed in most imaging systems for its advantages on pixel read-out and image reconstruction ways, however, in LPP, the clarity on image representation depends on the direction of the object in the image, or the directional dependency exists. In this paper,...
متن کاملQuad-pixel edge detection using neural network
One of the most fundamental features of digital image and the basic steps in image processing, analysis, pattern recognition and computer vision is the edge of an image where the preciseness and reliability of its results will affect directly on the comprehension machine system made objective world. Several edge detectors have been developed in the past decades, although no single edge detector...
متن کاملDesign and Preliminary Evaluation of CMOS Image Sensor with Pseudorandom Pixel Placement
The ultimate purpose of the image sensor is to obtain the clear image, especially the clear image we see. However, the jaggy which appears at the edge of the object in the image, which is composed of some pair of pixels, and it becomes the serious factor to defect the clearness of the image, since our eye severely perceives such jaggy, and it cannot be intrinsically eliminated by increased numb...
