    • A device, method and a computer program product are shown for correcting the focus error in an optical device, wherein in a first position of the optical device at least one focus detector is focused onto a given image plane of the target subject and the distance (d1) between the optical device and the given image plane is locked and wherein in a second position of the optical device following a reorientation of the optical device for achieving the desired framing of the image the shutter is released, the method comprising sensing a distance vector parallel to the focus plane after reorientation between the first position and the second position after reorientation, calculating a focus correction value (de) from the sensed distance vector and adding the focus correction value (de) as a corrective to the locked focus distance (d1).
    • 示出了用于校正光学装置中的聚焦误差的装置,方法和计算机程序产品,其中在光学装置的第一位置中,至少一个焦点检测器被聚焦到目标对象的给定图像平面上,并且距离( 在光学装置和给定的图像平面之间的d1)被锁定,并且其中在光学装置的第二位置跟随光学装置的重新定向以实现图像的期望的构图,快门被释放,该方法包括感测距离矢量 在重新定向后在第一位置和第二位置之间重新定向之后平行于聚焦平面,从感测的距离矢量计算聚焦校正值(de),并将聚焦校正值(de)作为校正值添加到锁定的聚焦距离(d1 )。
