摘要： An optical low pass filter (2) is formed, for example, by a birefringent plate so as to control the light beam separation width, thereby changing the cut-off frequency according to an imaging mode. The number of pixels of an imaging element (5) is set greater than the number of pixels corresponding to the dynamic image display resolution. In a still image capturing mode, the light beam separation width is set narrower so that the resolution of the imaging element (5) can be used as it is while suppressing generation of a false color to a certain degree. On the other hand, in a dynamic image capturing mode, the light beam separation width is set wider so that a high-frequency component corresponding to an unnecessary resolution component for an output image signal can be cut off and suppression of the false color can be performed strongly as compared to the still image capturing mode.

摘要： 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, 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.
摘要翻译：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指示对象图像和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，使得在透镜性能的评估测量操作的情况下，可以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，用户在测量结果画面上从MTF曲线图像中掌握对焦调整的必要性，如果需要，则调整与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。
