PURPOSE:To obtain a means for removing image geometric distortion in an image acquiring means mounted on satellite by using only image data. CONSTITUTION:A 1st detector 3 and a 2nd detector 14 for acquiring an image with a slight time delay due to the advancement of the satellite are mutually adjacently arranged on the optical system image forming face of this image acquiring device. A corresponding point of the image obtained from the 2nd detector 14 is detected in an image obtained from the 1st detector 3, the variation of posture generated during an period from the acqusition of the image by the 1st detector 3 up to the acquisition of the image by the 2nd detector 14 is calculated and integrated to calculate the variation of the posture of the image acquiring device. |
