Abstract
Abstract In an image forming apparatus, a color processing circuit calculates a ratio of color components of an image signal supplied from a CCD sensor. In a marker pen registering mode, its color components are detected by a marker color detecting section and stored in memory of a marker registering/canceling section. When the color of the marker pen is canceled, its color components are deleted from memory of the marker registering/canceling section. Since it is possible to cancel/register the marker pen, any general-purpose marker pen, in addition to a marker pen used exclusively for the apparatus, can be used upon editing. Thus, image editing can be implemented without using any designating means specific only to the apparatus.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
205 words
An apparatus for forming an edited image from an image which is read from a document, the edited image being defined with respect to an editing range designated on the document, the editing range being designated by a registered marker pen, comprising: means for setting a registration mode in which a mark of a new marker pen different from a previously registered marker pen is registered and an editing mode in which the editing range on the document is designated with the new marker pen; means for storing a previously registered marker pen signal corresponding to the previously registered marker pen; first converting means for converting the mark of the new marker pen to a new marker pen signal; means for storing one of the new marker pen signal and the previously registered marker pen signal; second converting means for converting the image read from the document and the editing range designated on the document into an image signal; means for comparing one of the new marker pen signal and the registered marker pen signal with the image signal to edit the image signal; and image forming means for forming the edited image on a basis of the image signal edited by the comparing means.
Claim 2
Independent Claim
205 words
An apparatus for forming an edited image from an image which is read from a document, the edited image being defined with respect to an editing range designated on the document, the editing range being designated by a registered marker pen, comprising: means for setting a registration mode in which a mark of a new marker pen different from a previously registered marker pen is registered and an editing mode in which the editing range on the document is designated with the new marker pen; means for storing a previously registered marker pen signal corresponding to the previously registered marker pen; first converting means for converting the mark of the new marker pen to a new marker pen signal; means for storing one of the new marker pen signal and the previously registered marker pen signal; second converting means for converting the image read from the document and the editing range designated on the document into an image signal; means for comparing one of the new marker pen signal and the registered marker pen signal with the image signal to edit the image signal; and image forming means for forming the edited image on a basis of the image signal edited by the comparing means.
Claim 3
Dependent Claim
31 words
The image forming apparatus according to claim 1, in which the second converting means includes means for reading the image on the document at a specific area in the edit mode.
Claim 4
Dependent Claim
40 words
The image forming apparatus according to claim 1, in which the first converting means includes means for reading a color of the mark of the new marker pen, marked on the document at a specific area in the registration mode.
Claim 5
Dependent Claim
41 words
The image forming apparatus according to claim 1, in which the first converting means includes means for reading an image density of the mark of the new marker pen, marked on the document at a specific area in the registration mode.
