Embodiment
First embodiment
With reference to Fig. 1, it shows the schematic diagram according to image processor of the present invention.Image processor 100 can be for carrying out scanner or the multi-function processor that colors of image is handled at an object.Image processor 100 comprises optical module 30, controlled processing unit 40 and interface 20 is set.
It is to be used to be provided with the color of object that desire is handled that interface 20 is set, and it also can be for independently being arranged at the circumscribed common apparatus (label does not illustrate) outside the image processor 100.Image processor 100 also can comprise interface (label does not illustrate), is used to connect the circumscribed common apparatus.The circumscribed common apparatus for example is a computer, and interface for example is USB (USB).This color of object is also predeterminable in controlled processing unit 40, and need not be provided with so that interface 20 to be set.
Optical module 30 comprises a plurality of primary lights 31 and sensing element 33.Sensing element 33 is used for sensed light signal, and produces the signal of telecommunication.Controlled processing unit 40 becomes the target gray level image according to electrical signal conversion, and can further handle or export thus image corresponding to above-mentioned object at the target gray level image.
Controlled processing unit 40 is controlled the projection time or the brightness of primary lights 31 according to set color of object, in the present embodiment, is that the projection time of control primary lights 31 is that example explains with controlled processing unit 40.Primary lights 31 for example is that (Light Emitting Diodes, LED) 31a, green LED 31b and blue LED 31c, object can be reflective object or transmission-type object to red light emitting diodes.After primary lights 31 is projected to reflective object or transmission-type object, reflect or transmit a plurality of light signals respectively.In the present embodiment, be that reflective object is that example explains with object.Sensing element 33 detects the light signal that object reflects, and produces a plurality of signals of telecommunication.Sensing element 33 for example be the contact-type image sensing element (Contact Image Sensor, CIS).
With reference to Fig. 1 and Fig. 2, Fig. 2 shows the flow chart according to colors of image processing method of the present invention simultaneously.Being convenient and describing, is that example describes with the color of object of the reflective object that weakens.At first, the beginning image treatment method, in step S201, the user utilizes the color of object that interface 20 is provided with the desire processing is set, and for example is orange (supposition GTG combination: red 255, green 204, blue 51).Generally can use several primary colors with different GTG intensity to the expression of coloured image, for example aforementioned to orange expression.For gray level image, as long as with single GTG value representation, for example 123).In the present embodiment, be with GTG value scope 0～255 redness, green, and blue three primary colors be combined into shades of colour, 0 minimum for brightness, 255 for brightness the highest.Because this expression to color is artificial definition, thus to its logically do opposite setting, the gradient scope is changed and the change of some other logic OR form all is fine.Then, in step S202, according to the redness of set orange (255,204,51) control primary lights 31, green, and blue LED 31a, 31b, and 31c, and be projected on the object with the controlled processing unit 40 of optical module 30.In step S203, sensing element 33 detects from the light signal that object reflected then, and the output signal of telecommunication.Because the orange areas on the object is strong than other color region to orange reflection of light, so in the signal of telecommunication of sensing element output, the difference of orange areas and background colour (for example white) diminishes, the purpose of the orange pattern of having realized weakening.Then in step S204, controlled processing unit 40 produces the target gray level image according to these signals of telecommunication.
In addition, controlled processing unit 40 also receives the set color of object in interface 20 is set, and analyzes thus by primary lights and form the required brightness ratio of this color of object.For example: it is orange (255 that interface 20 set color of objects are set, 204,51), 40 of controlled processing units analyze in view of the above redness, green, and blue three primary colors to form this orange required brightness ratio be 5: 4: 1 (also can adopt 255: 204: 51 or other proportional zoom).Perhaps, when the interface is set is a kind of external common apparatus that is independent of outside the image processor, also can directly utilize interface to be sent to controlled processing unit 40 brightness ratio of forming the required primitive color light of color of object.
