Particularly, as shown in Figure 3, can be at interior arrangement variable resistor loop (as shown in Figure 4), D/A converting circuit and the Bluetooth wireless transmission chip of pointer.Wherein, resistance value can be regulated within the specific limits by mechanical hook-up in the variable resistor loop, transformable electric signal is represented numerical value by the color that D/A converting circuit is converted between 0～255, and is transferred to main frame with digital signaling by the Bluetooth wireless transmission chip; Driver in the main frame color represent numerical value send to operating system and (or) the color menu that presets of current application program, and change current input color.
Fig. 5 shows the concrete physical construction in variable resistor loop.As shown in Figure 5, a shell of pointer is offered chute along diametric(al), a side device variable resistor on the chute inwall, and opposite side is other parts in variable resistor loop, both are connected by hard contact a, the b connection lead that is built in the slide block.Indicate scale 0～255 on the chute outer wall.
For example, can use the color mode of three primary colors (RGB) to carry out color adjustment.Particularly, in computing machine shown in Figure 1, the step of regulating color when utilizing the pointer Edit Document is as follows: thumb regulate red slide block (, color is selected module) to the maximal value place, D/A converting circuit (that is signal conversion module) is represented the R0 of numerical value by black with color, G0, B0 are converted to numerical value R255, G0, B0, and being transferred to host computer by Bluetooth wireless transmission chip (that is, signal transmission module), current input color promptly changes R255 into, G0, the redness of B0.
Certainly, in above-mentioned adjusting color process, also can use printing color pattern (CMYK) to regulate.In the CMYK pattern, by the proportioning of cyan, carmetta, yellow and black being regulated the adjusting that realizes color.Particularly, in computer system shown in Figure 1, the step of regulating color when using the pointer Edit Document is as follows: thumb adjusting cyan slide block (, color is selected module) to the maximal value place, regulate the carmetta slide block to the minimum value place, regulate yellow slide block to the maximal value place, and regulate the black slide block to the minimum value place, on behalf of numerical value, D/A converting circuit (that is signal conversion module) be converted to C 100% color, M0, Y100%, B0, and by the Bluetooth wireless transmission chip (promptly, signal transmission module) be transferred to host computer, current input color promptly changes green into.
That is to say, in computer system shown in Figure 1, realize that the step of color adjustment is: from least a primary colors, select the selected primary colors of a kind of conduct, and set the parameter of selected primary colors; Receive the parameter of selected primary colors, and handle, obtain chrominance signal, and chrominance signal is transferred to main frame according to the parameter of selected primary colors.
Fig. 2 is the logic diagram of computer system according to a second embodiment of the present invention.As shown in Figure 2, this computer system comprises: memory module 202 is used to store the corresponding relation between color adjustment signal and the chrominance signal; Pointer 204 comprises: color adjustment module 2042 is used for generating the first color adjustment signal according to user's input operation; Processing module 2044 is used to receive the first color adjustment signal, and determines pairing first chrominance signal of the first color adjustment signal according to described corresponding relation; Signal transmission module 2046 is used for first chrominance signal is transferred out; Main frame 206 comprises: color is selected module 2062, is used to receive first chrominance signal, and selects the color corresponding with first chrominance signal from color module.
Wherein, adopt between pointer and the main frame: the wired or wireless connection.
Wherein, the color adjustment module comprises:
First regulon, being used for the current color adaptation that can write of pointer is first color, generates the first color adjustment signal, and the first color adjustment signal is sent to signal transmission module;
Second regulon, being used for the current color adaptation that can write of pointer is second color, generates the second color adjustment signal, and the second color adjustment signal is sent to signal transmission module;
The 3rd regulon, being used for the current color adaptation that can write of pointer is the 3rd color, generates the 3rd color adjustment signal, and the 3rd color adjustment signal is sent to signal transmission module, wherein
When first regulon, second regulon, and the 3rd regulon when all inoperative, the color that pointer can be write is the color of main frame acquiescence.
Wherein, the structure of color adjustment module comprises: sliding structure, dial type structure, pressing structure, rotary structure, contact-type circuit type structure, photoelectric control formula structure, non-contact type electromagnetic induction structure.
Particularly, as shown in Figure 6, can be at pointer interior arrangement governor motion.Wherein, 4 in device is regulated the contact in the inwall of outer ring, is connected with regulating loop (as shown in Figure 7) respectively.Device has the contact in the inner core, is connected with regulating loop.The contact by back-moving spring and interior core apparatus together.By rotation outer ring or inner core, can realize the circuit shown in the adjustable type loop diagram.
For example, in computer system shown in Figure 2, be pre-existing in three regulons on the pointer, be respectively applied for the current color adaptation that can write of pointer to red, green and yellow.When each regulon on the pointer not being regulated, the color that pointer is write is the black of acquiescence.When thumb regulate on the pointer be used for the current color adaptation that can write of pointer for red regulon the time, this regulon generates red conditioning signal, processing module should redness adjusting signal Processing be a danger signal, and by signal transmission module this danger signal is transferred to main frame, thereby the current input color on the main frame has become redness.When thumb regulate on the pointer be used for the current color adaptation that can write of pointer for green regulon the time, red regulon lost efficacy, and had only this green regulon to work.The adjustment process of subsequent process and above-mentioned redness is similar.
That is to say, in computer system shown in Figure 2, realize that the step of color adjustment is: the corresponding relation between storage color adjustment signal and the chrominance signal; Input operation according to the user generates the first color adjustment signal; Receive the first color adjustment signal, and determine pairing first chrominance signal of the first color adjustment signal according to corresponding relation; First chrominance signal is transferred to main frame.
Certainly, above-mentioned pointer also can be used in the hand-written type mobile phone.In addition, also can regulate the HSL numerical value of representing tone, saturation degree and brightness by pointer, thus the color of the literal that the adjustment pointer is write out.
The above is embodiments of the invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within the claim scope of the present invention.
