Bildsensor, Verfahren zum Betreiben eines Bildsensors und Computerprogramm

(A1) Ein Bildsensor umfasst eine Mehrzahl von Bildelementen, die ausgelegt sind, um zugehoerige Bildelement-Signale zu liefern, die von auf die Bildelemente einfallenden Lichtintensitaeten abhaengig sind. Der Bildsensor umfasst eine Akkumulationsschaltung mit einer Mehrzahl von Ladungsspeicherelementen, wobei die Akkumulationsschaltung ausgelegt ist, um waehrend einer Phase Ladungen auf den Ladungsspeicherelementen in Abhaengigkeit von Bildelement-Signalen jeweils zugeordneter Bildelemente zu veraendern. Die Akkumulationsschaltung ist ferner ausgelegt, um eine Zuordnung zwischen Ladungsspeicherelementen und zugeordneten Bildelementen in aufeinanderfolgenden Phasen zu veraendern, so dass in einem Betrieb eine Ladung auf einem der Ladungsspeicherelemente von Bildelement-Signalen mehrerer Bildelemente in einer Mehrzahl von Phasen abhaengt.

US 20090009645 A1 UPAB: 20090205 NOVELTY - The sensor e.g. time-delayed integration complementary metal oxide semiconductor sensor (610), has an accumulation circuit including a set of charge storage elements e.g. accumulation capacitors. The accumulation circuit is configured to change charges on charge storage elements during a phase in dependence on image element signals of associated image elements, and to change an association between the storage elements and the image elements in successive phases such that the charge depends on image element signals of a set of image elements in a set of phases. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for operating an image sensor with a set of image elements configured to provide associated image element signals (2) a computer program for performing a method for operating an image sensor with a set of image elements configured to provide associated image element signals (3) a computer program for performing a method for operating an image sensor with a set of image elements configured to provide associated image element signals. USE - Image sensor e.g. time-delayed integration complementary metal oxide semiconductor image sensor and charge coupled device image sensor, for use in inspection systems and positioning systems, automobile systems, or automotive systems such as lane detection systems, pre-accident sensor technologies and pedestrian protection and topography measurements. ADVANTAGE - The sensor obtains a sharp mapping of pictures moved with respect to the sensor. The sensor allows a realization in a CMOS technology. The sensor allows a particularly cost-effective realization, when the realization of charge storage elements and the realization of a changeable association between charge storage elements and image elements are implemented in a conventional technology at a low cost. The sensor provides an operational speed that is increased by avoiding the bucket-brigade principle. The sensor avoids a loss of quality by smearing of charge.
