Abstract
The present disclosure is related to the acquisition of images with an image sensor. It is proposed a variable frame rate acquisition method that accommodates a fixed output frame rate. The exposure time is modified not only within the range of the current acquisition frame rate but the frame rate is modified to take into account the brightness level of the acquired image. The method of the present invention produces a fixed frame rate whatever the acquisition frame rate is defined by duplicating the images (lower acquisition frame rate) or skipping some images (higher acquisition frame rate).
