Marker dot detecting device for color image recording apparatus
First Claim
1. A marker dot detecting device for a color image recording apparatus, comprising marker dot detecting means for detecting a marker dot by detecting a plane size of binary image date having a preset marker color, said marker dot detecting means including template mask means having a first template mask in a predetermined first size and a second template mask in a predetermined second size larger than the first size, said second template mask including said first template mask, said template mask means outputting a marker dot detecting signal when a detected size of the marker dot is larger than that of said first template mask and smaller than that of said second template mask.

Abstract
A marker dot detecting device for a color image recording apparatus such as a color copying machine, color facsimile, or color printer. The marker dot detecting device includes a marker dot detecting unit for detecting a marker dot by detecting a plane size of binary image data having a preset marker color. Further, the marker dot detecting unit includes a template mask unit having a first template mask in a predetermined first size and a second template mask in a predetermined second size larger than the first size, the second template mask including the first template mask. The template mask unit outputs a marker dot detecting signal when a detected size of the marker dot is larger than that of the first template mask and smaller than that of the second template mask.

5. A color image recording apparatus for performing an editing process based on a marker dot detection, comprising:
-
original input means for supplying an input signal; means for separating the input signal supplied from said original input means into and for supplying a color signal and a non-color signal; and means for detecting a marker dot by comparing the color signal supplied from said separating means with a template, said template holding a measure for determining an upper limit of the size of the marker dot to be detected and a measure for determining a lower limit of the size of the marker dot. - View Dependent Claims (6, 7, 8)
