  • Image pickup apparatus having a mask for defining the extent of the image to be reproduced
    Patent number: 5159648
    Abstract: An image pickup device for viewing an image on a wall surface includes a mask for defining the extent of the focal plane of a viewed image which will be reproduced by a linear image sensor positioned to scan the masked area. Binary data representative of the scanned image is generated and controls a printer which reproduces the masked portion of the image. The size of the masked image is restored to the full size capability of the printer by a data scaling circuit which precludes the need for utilizing a zoom lens in the image pickup device.
