In order to obtain high signal noise ratio and high resolution image

the requirements for the scope of scroll angle and pitch angle is put forward by analyzing the influence of aircraft scroll and pitch movement on image quality. According to the mechanism of camera image motion

the formula for calculating the image motion which caused by scroll and pitch of aerocraft and the image motion are given. The image quality is evaluated by way of the Modulation Transform Function（MTF）

and the scopes of scroll angle and pitch angle that can meet the requirements of the space camera image quality are computed. Furthermore

the influence of scroll angle and pitch angle on ground pixel resolution is analyzed. From calculations

the following conclusions are derived. When the control error of scroll angle and pitch angle is 0.1° during the imaging

the angle of axis of sight caused by scroll angle and pitch angle is not greater than 4.8°; or when the control error of scroll angle and pitch angle is 0.05° during the imaging

the angle of axis of sight caused by scroll angle and pitch angle is not greater than 9.5°

which can meet the requirements of the integration progression is 96 and MTF is not less than 0.95. The experimental results indicate that the method proposed is simple and easy to implement

which is suitable for the research on image quality of space camera.
