摘要：
The present invention relates to a system for displaying a video image to a user having a visual impairment. The system comprises a video camera, a data storage device, a processor and an image display device for displaying processed images in a display region. The processor is operative to perform at least one of the operations of (i) including in the display region, a marker at a location offset from a centre of the display region, whereby if the user, who suffers from blurred vision at the centre of the users visual field, looks at the marker, the user sees the captured image in focus or (ii) deforming a portion of the captured image by a correction matrix, whereby, upon displaying the processed images by the display device, the correction matrix corrects a deformation in a corresponding portion of the visual field of the user due to the visual impairment.
