1. A night vision device arranged for acquiring and displaying images in real-time, the night vision device comprising: i) an imaging sensor comprising a radiation sensitive array for acquiring an image, ii) a readout circuit connected to the radiation sensitive array for reading out the image, iii) a signal processor for processing the image for obtaining a processed image, and iv) a display 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 by a) initializing an exposure of a row, and b) reading out its contents after said exposure, for sequentially providing subsets of pixels), each subset of pixels corresponding to one row or a subset of the rows of sensor pixels or a subset of pixels from a single row; 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, and wherein the direct view system comprises a further imaging sensor and a further readout circuit, the further imaging sensor comprising a further radiation sensitive array for acquiring a further image, the further readout circuit being connected to the further radiation sensitive array for reading out the further image, the further radiation sensitive array being arranged in rows of further sensor pixels, the further readout circuit being a further rolling shutter circuit for sequentially reading out the rows of further sensor pixels for sequentially providing further subsets of pixels, and wherein the direct view system is configured for synchronously displaying the image and the further image on the display by: (1) the rolling shutter circuit and the further rolling shutter circuit being configured for synchronously providing the subset of pixels and one of the further subsets of pixels by substantially synchronously reading out corresponding portions of the image and the further image; and (2) the signal processor being configured for, on availability of the subset of pixels and the further subset of pixels, combining the subset of pixels with the further subset of pixels for obtaining the processed subset of pixels, wherein the radiation sensitive array has a first spatial resolution, the further radiation sensitive array has a second spatial resolution, the second spatial resolution being lower than the first spatial resolution and the further rolling shutter circuit being configured for reading out the further image with a second readout speed that is lower than a first readout speed of the rolling shutter circuit for enabling said synchronously providing the subset of pixels and the further subset of pixels, and wherein the rolling shutter circuit is clocked at a first pixel clock for providing the first readout speed and the further rolling shutter circuit is clocked at a second pixel clock for providing the second readout speed.
