Document Type and Number:
Japanese Patent JPH0616169
Kind Code:
B2
Abstract:
An image contour data generating apparatus comprises a digitizer for holding an original film having a section which is bounded by a particular contour. The digitizer serves for inputting approximate information regarding the position of the contour on the original film. The apparatus also includes an image sensor in the digitizer which is moved to the inputted approximate position of the contour for detecting the accurate image contour position at that position, an arithmetic device for calculating an absolute contour line position from the inputted approximate contour position data and from the accurate image contour position data obtained by the image sensor, and a memory for storing the contour position data obtained from the calculation. The apparatus is such that the original film is not moved from its location on the digitizer from the time when the approximate image contour information is inputted until after the accurate contour position is detected.
