Abstract
An improved image pickup device or method and an improved image processing device or method which directly projects a region specifying image on an object to specify and focus the object within a predetermined region without employing any image display unit so as to take an image of the object and judge the quality of the taken image. An image pickup device (2) includes an image pickup means (22) for taking an image of an object (1) which is focused through a lens (21), and a projecting means (25) for projecting an image (27p) of a predetermined shape on the object. An image processing device (4) compares the image taken by the image pickup device (2) with a predetermined image stored beforehand to produce a result of such comparison.
Claims15
An image pickup device for providing a model image and an input image in combination with an image processing device which registers said model image and conducts a matching process by searching for an image which agrees with said registered model image within a measurement region included in said input image, where in the improvement comprises:
- projecting means in said image pickup device for directly projecting a registration region designating image and a measurement region designating image onto an object for showing a registration region of which image is registered as said model image and said measurement region to an operator.
An imaging device comprising:
- an image processing device;
- an image pickup device for providing a model image and an input image of an object to said image processing device, said image processing device registering said model image;
- a projection light source;
- and
- a slit plate disposed between said projection light source and said object, said slit plate and said projection light source cooperating to directly project a registration region designating image and a measurement region designating image onto said object, said registration region designating image showing a registration region of said registered model image,
- wherein said image processing device conducts a matching process by searching for an image which agrees with said registered model image within said measurement region in said input image.
