This paper presents a 4.1 megapixel, 280 frames/s, back-illuminated, stacked, global shutter (GS) CMOS image sensor with array-parallel analog-to-digital converter (ADC) architecture for region-control applications. The sensor solves an image distort

A 4.1Mpix 280fps stacked CMOS image sensor with array-parallel ADC architecture is developed for region control applications. The combination of an active reset scheme and frame correlated double sampling (CDS) operation cancels Vth variation of pixe

Compression is routinely used in printing pipelines. While both lossless and lossy compression methods exist for compressing halftones, dispersed types of halftones remain difficult to compress given their very nature. In recent years researchers hav

We propose and consider a secure printing system for the distributed printing of documents and images over the World Wide Web. This system enables secure sharing, commerce, and collaboration using images and documents. The main feature of the system

We describe a procedure by which Joint Photographic Experts Group (JPEG) compression may be customized for gray-scale images that are to be compressed before they are scaled, halftoned, and printed. Our technique maintains 100% compatibility with the

Traditional subband coding, where each subband is encoded independently, has been shown by Fischer (1992) to be suboptimum for encoding Gaussian sources in the rate-distortion sense. We show here that if we use prediction across subbands when encodin

Error diffusion is a procedure for generating high quality bilevel images from continuous-tone images so that both the continuous and halftone images appear similar when observed from a distance. It is well known that certain objectionable patterning

We propose a multi-component metric for the evaluation of digital or video cameras under wide dynamic range (WDR) scenes. The method is based on a single image capture using a specifically designed WDR test chart and light box. Test patterns on the W
