Abstract

PROBLEM TO BE SOLVED: To allow the user to easily grasp a color mode selected at present and an output color and to suppress mis-copy resulting from the color mode and the output color. SOLUTION: A display section is made up of a ROM 301, a CPU 302, a RAM 303, a VRAM 304, a display control section 305 and a color display section 306 and when an operation section selects a color mode, the color used by the color display section 304 in response to the selected color is changed. The revision is made by rewriting the content of the VRAM 304 or the display control section 305 is used to change the display color. As a color used by the color display section 306, a background color, a display character color, or a color of a mode selection button is selected. Then the relation between the displayed color in use and the selected mode is grasped by the user.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus having a plurality of color modes and outputting a read original according to the color mode.

[0003] Among them, Japanese Patent Application Laid-Open No. Hei 2-203663 discloses a read command means for commanding reading of a registered color, and a method for embodying the color to identify the color read by the read command means. There is disclosed a copying apparatus that includes a display unit that displays the converted colors and uses the registered colors for copy editing processing related to the colors of the document.

Japanese Patent Application Laid-Open No. 221461/1990 discloses a display unit which embodies and displays a color to be output, setting means for arbitrarily setting the color of the display content of the display unit, and setting means by the setting means. And a determining unit for determining a color of the displayed content as an output color, and forming a color image on a sheet based on the color determined by the determining unit.

Japanese Patent Laid-Open Publication No. Hei 2-304579 discloses an area setting means for dividing an image area, a color designating means for designating a color for each of the divided areas divided by the area setting means, Area indicator lights corresponding to each of the divided areas, color indicator lights corresponding to each of the specifiable colors, and the same number of the specifiable colors, and each of the divided areas and their designated colors are assigned to each of the divided areas. Display control means for controlling the area indicators and the color indicators so as to be sequentially displayed for each color, and a color image editing function for forming a plurality of color hard copy images by dividing the image area into colors. A multi-color image forming apparatus having the same is disclosed.

[0006]

A variety of color copiers (color image forming apparatuses) capable of performing some editing on a color image as described above are known and sold. In such color copying, a mode for copying a color original in full color, a mode for copying in black and white original or black and white, a mode for copying in an arbitrary registered color, and a mode for copying in two colors are prepared.

However, since there are various types of color modes, a user may make a copy without realizing that a color mode different from the one desired by the user is selected, resulting in a miscopy. Was.

Therefore, in the invention described in Japanese Patent Application Laid-Open No. 2-203666, the registered colors are read and confirmed to prevent erroneous copying.
It has not been possible to easily grasp which color mode is selected. For this reason, there is a case where a mis-copy occurs without understanding the relationship between the color mode and the output color. These circumstances are the same in the other known examples.

SUMMARY OF THE INVENTION The present invention has been made in view of such a situation of the prior art, and its object is to allow a user to easily grasp the currently selected color mode and output color. It is an object of the present invention to provide an image forming apparatus capable of suppressing the occurrence of miscopy caused by the above.
