Abstract: The size of the camera sensor devices allows a great number of applications such as medical applications. The image sensor itself is approximately the size of a cube of 1 mm3. Such devices are used for endoscopy in the medical field or to be integrated in alarm clock or a watch for surveillance purpose.

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).
