摘要:
It is disclosed that in order to form an image of which the continuity is not lost from the image information of an area in which a double image exists and the vicinity thereof and prevent the deterioration of the image, an image processing portion to which video signals from left and right image taking systems are input has an image input portion, an image conversion portion and a synthesized image memory. The image conversion portion has a corresponding point sampling unit for sampling pairs of corresponding points corresponding to the same portion of an object from the video signals, a double image area-dividing unit for effecting the area division of a double image on the basis of the information of the three-dimensional positions of the sampled pairs of corresponding points, a double image mode-discriminating judging unit for determining an image of greater probability with which each double image is connected to a double image non-generating area, and an either image of two systems and common images of two ones simultaneous-removal unit which uses as synthesized image forming data the image determined to be more probably connected to the double image non-generating area by the double image mode-discriminating judging unit, and removes the other image.

The multieye imaging apparatus has an image correlation processing unit for effecting a correlation operation from image signals obtained from a plurality of pick-up-image systems. The apparatus also has an image synthesizing processing unit for joining the other image on the basis of one image from the image signals relative to the correlation operation performed by the image correlation processing unit.
摘要:
A multi-lens imaging apparatus comprises a plurality of imaging optical systems in which an angle formed by optical axes is varied by inclining an optical axis of at least one optical system between a first state and a second state, and a plurality of image sensing means for detecting an image of an object imaged through the imaging optical systems. A photosensitive surface of the image sensing means corresponding to the at least one optical system is inclined with respect to the optical axis, and the inclined angle is established between an imaging surface being conjugated with the object surface in the first state and an imaging surface being conjugated with the subject surface in the second state, thereby reducing unsharpness amount generating at the periphery portions of the screen.

摘要:
A method of detecting a positional deviation between a mask and a wafer, wherein a radiation beam having a predetermined intensity distribution is projected to an alignment pattern of the mask whereby a signal beam is produced, and wherein the positional deviation of the mask and the wafer is determined on the basis of the signal beam. The improvements reside in detecting a deviation of the position of incidence of the radiation beam upon the mask from a predetermined position, on the basis of the signal beam; relatively positioning the radiation beam and the mask so as to substantially correct the detected deviation; and determining the positional deviation of the mask and the wafer by using the relatively positioned radiation beam.

摘要:
A method of detecting relative positional deviation of first and second substrates, wherein first and second marks with optical powers are formed on the first and second substrates. A radiation beam is projected to the first substrate and, as a result, the first and second marks produce a signal beam whose position of incidence upon a predetermined plane is changeable with the relative positional deviation of the first and second substrates. A sensor is disposed adjacent to the predetermined plane and receives the signal beam to produce an output signal corresponding to the position of incidence of the signal beam upon the sensor. Here, a reference mark is provided to produce, when irradiated with a radiation beam, a reference beam so that it advances along a light path substantially the same as the light path for the signal beam to the sensor when the first and second substrates are in a predetermined positional relation. The produced reference beam is received by the sensor, whereby a reference signal corresponding to the position of incidence of the reference beam upon the sensor is obtained. The relative position of the first and second substrates can be detected on the basis of the output signal and the reference signal.

A telephoto lens is provided, in succession from the object side to the image surface side, with a first lens component having a positive refractive power and a second lens component having a negative refractive power. At least one curved lens surface of the second lens component is inclined relative to the optic axis to thereby deflect the image. Particularly the lens surface which near the image surface is inclined.
