摘要： This video system includes a camera system and a video converter. The camera system includes an image pickup unit that captures a subject and obtains a pixel signal thereof, and a first processing circuit that generates two video signals from the pixel signal while respectively carrying out mutually-different adjustments and transmits transmission information obtained by adding information related to the respective adjustments of the video signals to one of the video signals. The video converter extracts the information related to the respective adjustments of the video signals from the transmission information and includes a second processing circuit that generates, on a basis of these pieces of information related to the adjustments, a restoration pixel signal by inverse-transforming one of the video signals included in the transmission information, and also generates a video signal corresponding to the other one of the video signals by performing an adjustment for the other one of the video signals on this restoration pixel signal.

摘要： Le circuit de détection comporte un détecteur (1) connectée à un noeud d'intégration (N). Un circuit de polarisation (5) permet de polariser le détecteur (1) entre un premier état de polarisation et un deuxième état flottant. Le potentiel du noeud de rétention (N) se trouve à une valeur cible lorsque le circuit de polarisation polarise le détecteur dans le premier état et évolue lorsque le détecteur est à l'état flottant. Un circuit de mesure sans perte de charge délivrant une valeur représentative du potentiel présent sur le noeud d'intégration N. Un circuit de transfert des charges électriques pour déplacer les charges électriques depuis un condensateur parasite (C PD ) de la photodiode (1) vers un condensateur d'intégration (C INT ). Une borne de sortie délivre une tension représentative du potentiel présent sur la deuxième borne du premier condensateur (C INT ).

摘要： An image processing apparatus (10) for a radiation image obtains radiation image data obtained by radiation imaging using a radiation detector (11), and dark current data based on a signal obtained from the radiation detector without irradiating any radiation from a radiation generator (20). The image processing apparatus generates correction data by changing a ratio of frequency components based on the dark current data, and corrects the radiation image data based on the generated correction data.
