Title
(EN) ACQUIRING AND DISPLAYING IMAGES IN REAL-TIME
(FR) ACQUISITION ET AFFICHAGE D'IMAGES EN TEMPS RÉEL
Abstract
(EN) An imaging device (100) for acquiring and displaying images in real-time, the imaging device comprising i) an imaging sensor (110) comprising a radiation sensitive array (120) for acquiring an image (142), ii) a readout circuit (140) connected to the radiation sensitive array for reading out the image, iii) a signal processor (160) for processing the image for obtaining a processed image (162), and iv) a display (180) for displaying the processed image, the radiation sensitive array being arranged in rows of sensor pixels and the display being arranged in rows of display pixels, and wherein the readout circuit is a rolling shutter circuit for sequentially reading out the rows of sensor pixels for sequentially providing subsets of pixels, the signal processor is configured for, on availability of one of the subsets of pixels, processing the subset of pixels for providing a processed subset of pixels, and the display is configured for, on availability of the processed subset of pixels, displaying the processed subset of pixels on a thereto corresponding subset of display pixels for displaying the processed image sequentially on the rows of display pixels.
(FR) Dispositif imageur (100) servant à acquérir et à afficher des images en temps réel, le dispositif imageur comprenant i) un capteur imageur (110) comprenant un réseau sensible au rayonnement (120) servant à acquérir une image (142), ii) un circuit de lecture (140) relié au réseau sensible au rayonnement, servant à lire l'image, iii) un processeur de signal (160) servant à traiter l'image pour obtenir une image traitée (162), et iv) un affichage (180) servant à afficher l'image traitée, le réseau sensible au rayonnement étant agencé en rangées de pixels capteurs et l'affichage étant agencé en rangées de pixels d'affichage. Le circuit de lecture est un circuit de lecture en mode volet roulant servant à effectuer une lecture séquentielle des rangées de pixels capteurs pour produire séquentiellement des sous-ensembles de pixels ; le processeur de signal est conçu, dès qu'un des sous-ensembles de pixels est disponible, pour traiter ce sous-ensemble de pixels et produire un sous-ensemble de pixels traité ; et l'affichage est conçu, dès que le sous-ensemble de pixels traité est disponible, pour afficher le sous-ensemble de pixels traité sur un sous-ensemble de pixels d'affichage qui lui correspond de manière à afficher l'image traitée séquentiellement sur les rangées de pixels d'affichage.
