  • Publication number: 20130201374
    Abstract: A camera, more particularly for recording aerial images from aircraft, comprising a lens and at least one digital, areal image sensor fixed on a carrier element and having a predetermined pixel size, which image sensor has a curvature, more particularly caused by the fixing on the carrier element within a specific tolerance range. The lens at least partly brings about optical compensation of the curvature of the digital areal image sensor.

  • Patent number: 5784103
    Abstract: It is known to adjust the width/height ratio (aspect ratio) in charge coupled imaging devices in that a number of columns may or may not be used on either side of the imaging matrix. It is possible in this manner, for example, to reduce the aspect ratio to 4/3 starting from a device with an aspect ratio of 16/9 corresponding to a widescreen TV. Practice has shown that this reduction in the width impairs the quality of the imaging device in the 4/3 mode. According to an aspect of the invention, an FT device with an aspect ratio of 4/3 is used and operated as a 4-phase CCD in the 4/3 mode. To obtain the 16/9 aspect ratio, the height of the device is reduced in that selected lines are not used. For this purpose, the sensor matrix is operated as a 3-phase CCD, whereby the number of lines in vertical direction is increased.
