This article presents a color light detection system integrated in 130 nm CMOS technology. The sensors and corresponding electronics detect light in a CIE XYZ color luminosity space using on-chip integrated sensors without any additional process steps, high-resolution analog-to-digital converter, and dedicated DSP algorithm. The sensor consists of a set of laterally arranged integrated photodio...

With the expansion of digital photographic content stored online and concurrent proliferation of capturing devices, the management and visualization of personal photo collections have become very challenging tasks. In order to gain insight into novel ways of handling and representing large personal photo collections, this paper presents results of a user experience study into novel visualizatio...

We describe general web-based photo management solutions. We will see how thesesolutions provide users with search and browsing functionalities but little more than this. We will then describe systems that take photo management to a further step and provide users with additional information. The systems that we first describe are contextbased services that provide users with some information. T...

We live in a society where the large majority of the population has a cameraequipped smartphone. In addition, hard drives and cloud storage are getting cheaper and cheaper, leading to a tremendous growth in stored personal photos. Unlike photo collections captured by a digital camera, which typically are pre-processed by the user who organizes them into event-related folders, smartphone picture...

In recent years, advertisers and magazine editors have been widely criticized for taking digital photo retouching to an extreme. Impossibly thin, tall, and wrinkle- and blemish-free models are routinely splashed onto billboards, advertisements, and magazine covers. The ubiquity of these unrealistic and highly idealized images has been linked to eating disorders and body image dissatisfaction in...

This paper describes a prototype smart imager capable of adjusting the photo-integration time of multiple regions of interest concurrently, automatically and asynchronously with a single exposure period. The operation is supported by two interwined photo-diodes at pixel level and two digital registers at the periphery of the pixel matrix. These registers divide the focal-plane into independent ...
