METHOD AND DIGITAL VIDEO CAMERA FOR IMPROVING THE IMAGE QUALITY OF IMAGES IN A VIDEO IMAGE STREAM

摘要

The invention relates to a method for improving the image quality of images in a video image stream captured by a digital video camera (5, 5 '). The method includes capturing a first subset of images by the digital video camera (5, 5 '); Outputting the images of the first subset of images as the video image stream; Before capturing an image of the second subset of images, the image sensor 14, 14 'and / or the lens 12, 12' of the digital video camera 5, 5 ' To a respective test position; Capturing a second subset of the images using the digital video camera (5, 5 '), wherein capturing a second subset of the images comprises capturing a first subset of the images And is interspersed; Comparing the image of the first subset of images with the image of the second subset of images; Determining, based on the comparison, whether the image of the second subset of images represents an improved image quality compared to the image of the first subset of images; And initiating an image quality improvement operation on the digital video camera (5, 5 ') if the image of the second subset of images indicates an improved image quality compared to the image of the first subset of images . The invention also relates to a digital video camera (5, 5 ') for improving the image quality of images in a video image stream.
