    • A MTF measuring system includes measurement result screen data indicative of an object image and an MTF curve image are generated in accordance with the object image data obtained by photographing the object and the MTF curve image data indicative of the MTF curve generated from MTF data that become an index to evaluate lens performance. The measurement result screen based on the generated measurement result screen data is displayed on a real time basis in the case of evaluation measurement operations of the lens performance. A user can grasp the necessity for a focus adjustment from the MTF curve image on the measurement result screen. If necessary, the user can adjust the focus of the object displayed together with the MTF curve image, and at the same time can evaluate the lens performance from the MTF curve image.
    • MTF测量系统包括指示对象图像的测量结果屏幕数据,并且根据通过拍摄对象获得的对象图像数据和指示从MTF数据生成的MTF曲线的MTF曲线图像数据生成MTF曲线图像 评估镜头性能的指标。 在透镜性能的评价测量操作的情况下,基于生成的测量结果画面数据的测量结果屏幕被实时显示。 用户可以从测量结果画面上的MTF曲线图像中掌握聚焦调整的必要性。 如果需要,用户可以调整与MTF曲线图像一起显示的对象的焦点,同时可以从MTF曲线图像评估镜头性能。

The measurement result screen based on the generated measurement result screen data is displayed, so that the measurement result screen indicative of the object image and the MTF curve image can be displayed on a real time basis in the case of evaluation measurement operations of the lens performance. As a result, a user grasps necessity for a focus adjustment from the MTF curve image on the measurement result screen, if necessary, adjusts focus of the object displayed together with the MTF curve image, and at the same time can evaluate the lens performance from the MTF curve image.
    • 根据通过拍摄对象获得的对象图像数据和表示从成为指标的MTF数据生成的MTF曲线的MTF曲线图像数据来生成表示对象图像和MTF曲线图像的测量结果画面数据,以评估透镜 性能。 显示基于生成的测量结果画面数据的测量结果画面,从而可以在透镜性能的评估测量操作的情况下实时显示指示对象图像和MTF曲线图像的测量结果画面 。 结果,如果需要,用户可以从测量结果画面上的MTF曲线图像中掌握聚焦调整的必要性,调整与MTF曲线图像一起显示的对象的焦点,并且同时可以评估来自 MTF曲线图像。
