METHOD FOR CAPTURING AND DISPLAYING A VARIABLE-RESOLUTION DIGITAL PANORAMIC IMAGE

摘要

The invention relates to a method for capturing a digital panoramic image comprising a step whereby a panorama is projected onto an image sensor using a wide-angle lens. According to the invention, the wide-angle lens has an image point distribution function which is non-linear in relation to the field of view of the object points of the panorama, such that at least one area of the image obtained is expanded while at least one other area of said image is compressed. During the display of a panoramic image obtained in compliance with said method, a step is provided for involving the correction of the non-linearity of the initial image which is performed using a function which is reciprocal to the lens non-linear distribution function or using the non-linear distribution function. The invention is advantageous as the image is expanded and the definition in the most useful areas of said image is improved. The inventive method is particularly suitable for video surveillance, video teleconferencing and video conferencing and for digital panoramic photography.
