Image Recording System with a Rapidly Vibrating Global Shutter CMOS Sensor

摘要

Image recording system, having: a digital camera with a two-dimensional global shutter CMOS sensor array with photosensitive sensor elements; shifting means, which are configured to produce a relative shifting between an object image and the sensor array between two positions; and a control unit, which is configured to control the shifting means between the recording of successive partial images, taking into account a color mosaic filter placed in front of the sensor elements for the simultaneous recording of a red, green, and blue color separation in such a way that by means of successive partial images recorded at the two positions for all image points of an image obtained by combining the partial images, color information for green is available; and an image processing unit, which is coupled to the digital camera and is configured to calculate a result image or a result image sequence, which includes at least two result images, based on at least three successive partial images.

1. An image recording system, comprising:
a digital camera with a two-dimensional global shutter CMOS sensor array with photosensitive sensor elements; at least one shifting actuator, which is configured to produce a relative shifting between an object image and the sensor array between two positions; and a control unit, which is configured to control the shifting means between the recording of successive partial images, taking into account a color mosaic filter placed in front of the sensor elements for the simultaneous recording of a red, green, and blue color separation in such a way that by means of successive partial images recorded at the two positions for all image points of an image obtained by combining the partial images, color information for green is available; and an image processing unit, which is coupled to the digital camera and is configured to calculate a result image or a result image sequence, which includes at least two result images, based on at least three successive partial images, which are recorded in alternating fashion at the two positions at chronologically equidistant intervals, and the first partial image and the third partial image have been recorded at the same position.
