Abstract
Image-shearing apparatus comprises a television camera tube for receiving an optical image from a microscope objective. Electrical circuitry receives the output signal from the camera tube and provides a display image in which a horizontal band is uniformly shifted relative to the remainder of the frame. The amount of lateral shift is adjustable, preferably in a calibrated manner. Then, by registering an edge portion of the image in the shifted band with an adjacent edge portion outside the band, the apparatus may be used with particular advantage in sizing.
Claims16
Image-shearing apparatus comprising a television camera tube for receiving an optical image from a microscope objective and producing an output signal representative of the image;
- electrical circuitry coupled to said camera and responsive to the output signal for providing one or more display signals;
- and at least one television display unit which has a monitor and is coupled to said electrical circuitry and responsive to the one or more display signals to produce on said television monitor an image corresponding to the optical image in which at least one horizontal band of each frame is uniformly shifted laterally by a selectively variable amount relative to the remainder of the frame.
Image-shearing apparatus comprising a television camara tube for receiving an optical image from a microscope objective and producing an output signal representative of the image, and electrical circuitry coupled to said camera and responsive to the output signal for providing one or more display signals for a television display unit such as to produce on a television display unit an image corresponding to the optical image in which at least one horizontal band of each frame is uniformly shifted laterally by a selectively variable amount relative to the remainder of the frame.
A method of measuring distance between line elements of an optical image, the method including the steps of forming a television display of an image of an object, uniformly shifting at least one horizontal band of each frame of the television display relative to the remainder of the frame, to form relatively displaced portions of the image in adjacent portions of the field of display, and carrying out calibrated adjustment of the relative displacement of the image portions until a line element of one image portion is brought into alignment with a line element of an image portion in an adjacent portion of the field.
