The conventional input device 1 includes a usb interface 11, a red light emitting unit 12, a green light emitting unit 13, a blue light emitting unit 14, a microprocessor 15, and a driving circuit 16, wherein the color light emitting element is composed of the red light emitting unit 12, the green light emitting unit 13, and the blue light emitting unit 14. The usb interface 11 is electrically connected to the host computer 10 and the microprocessor 15, and the driving circuit 16 is connected to the microprocessor 15, the red light emitting unit 12, the green light emitting unit 13, and the blue light emitting unit 14.

Please refer to fig. 3, which is a block flow diagram illustrating a color adjustment method of a color light emitting device according to a preferred embodiment of the present invention. The method comprises the following steps:

Step B2: the second white light beam is measured to obtain a second luminance value and a second chrominance value corresponding to the second white light beam.

In step C4, when the third chromaticity value corresponding to the third white light beam is determined to be consistent with the second chromaticity value, step C5 is performed. On the contrary, when the third chromaticity value corresponding to the third white light beam is determined to be inconsistent with the second chromaticity value, the step C1 is performed again.
The step D comprises the following steps:
step D1: and adjusting the current value corresponding to the white light-emitting unit according to the third brightness value to enable the white light-emitting unit to generate a fourth white light beam.
Step D2: it is determined whether a fourth luminance value corresponding to the fourth white light beam coincides with the third luminance value.
Step D3: and acquiring a current value corresponding to the white light-emitting unit as a second adjusting parameter.
In step D2, when the fourth luminance value corresponding to the fourth white light beam is determined to be consistent with the third chrominance value, step D3 is performed. Otherwise, when the fourth luminance value corresponding to the fourth white light beam is determined to be inconsistent with the third chrominance value, step D1 is performed again.
The operation of the color adjustment method performed by the input device 2 with color adjustment function according to the present invention will be described. Referring to fig. 2 and fig. 3 again, the driving method of the color adjustment method of the present invention includes two driving methods: first, the control module 23 can be set to automatically perform the color adjustment method when the input device 2 with the color adjustment function is activated. Second, the user can manually start the color adjustment method through a control interface (not shown) installed in the electronic device 201 (e.g., a computer host). First, in step A, the control module 23 performs steps A1-A3: the red light emitting unit 221 is driven to make the red light emitting unit 221 generate a first red light beam, and the green light emitting unit 222 is driven to make the green light emitting unit 222 generate a first green light beam, and the blue light emitting unit 223 is also driven to make the blue light emitting unit 223 generate a first blue light beam. The first red light beam, the first green light beam and the first blue light beam are mixed to form a first white light beam. On the other hand, the control module 23 performs step a 4: the white light emitting unit 224 is driven such that the white light emitting unit 224 generates a second white light beam.
After step a is completed, the control module 23 proceeds to step B1: the light measuring device 202 is activated and measures the first white light beam to obtain a first luminance value L1 and a first chrominance value (Xw1, Yw1) corresponding to the first white light beam. On the other hand, step B2 is performed: the second white light beam is measured by the photometry device 202, and a second luminance value L2 and a second chromaticity value (Xw2, Yw2) corresponding to the second white light beam are obtained.
Next, the control module 23 proceeds to step C1: the current value corresponding to the red light emitting cell 221 is adjusted based on the second chromaticity value (Xw2, Yw2) so that the red light emitting cell 221 generates the second red light beam. Similarly, step C2 is performed: the current value corresponding to the green light emitting unit is adjusted based on the second chromaticity value (Xw2, Yw2) so that the green light emitting unit 222 generates the second green light beam, and the step C3 is performed: the current value corresponding to the blue light emitting cell 223 is adjusted according to the second chromaticity value (Xw2, Yw2) so that the blue light emitting cell 223 generates the second blue light beam. At this time, the second red light beam, the second green light beam, and the second blue light beam are mixed to form a third white light beam, wherein the third white light beam is measured by the light measuring device 202, and a third luminance value L3 and a third chromaticity value (Xw3, Yw3) corresponding to the third white light beam are obtained.
After obtaining the third chromaticity values (Xw3, Yw3), the control module 23 determines whether the third chromaticity values (Xw3, Yw3) corresponding to the third white light beam are consistent with the second chromaticity values (Xw2, Yw2) corresponding to the second white light beam, i.e., step C4 is performed. Wherein, determining whether the chromaticity values of the two are consistent is determined by determining whether the coordinates of the third chromaticity value (Xw3, Yw3) and the second chromaticity value (Xw2, Yw2) in the CIE 1931 color space are consistent, and the CIE 1931 color space is well known by those skilled in the art and is not described herein again. In the preferred embodiment, the control module 23 employs the following settings: and when the X coordinate difference and the Y coordinate difference of the third chrominance value (Xw3, Yw3) and the second chrominance value (Xw2, Yw2) are respectively less than 0.01, judging that the third chrominance value (Xw3, Yw3) is consistent with the second chrominance value (Xw2, Yw 2). Otherwise, the third chromaticity values (Xw3, Yw3) are judged to be inconsistent with the second chromaticity values (Xw2, Yw 2). The above-mentioned determination standard set to 0.01 can be changed according to the requirement, but the invention is not limited thereto.
In step C4, when the control module 23 determines that the third chromaticity values (Xw3, Yw3) are consistent with the second chromaticity values (Xw2, Yw2), step C5 is performed. On the contrary, when the third chromaticity values (Xw3, Yw3) are determined to be inconsistent with the second chromaticity values (Xw2, Yw2), step C1 is performed again to adjust the current values of the red light-emitting unit 221, the green light-emitting unit 222 and the blue light-emitting unit 223 again until the third chromaticity values (Xw2, Yw2) of the third white light beam generated after adjustment are consistent with the second chromaticity values (Xw2, Yw 2). When the step C4 is completed and the third chromaticity value (Xw2, Yw2) of the third white light beam is consistent with the second chromaticity value (Xw2, Yw2), the control module 23 obtains the current value corresponding to the red light-emitting unit 221, the current value corresponding to the green light-emitting unit 222 and the current value corresponding to the blue light-emitting unit 223 as the first adjustment parameter, that is, performs the step C5.
After step C is completed, the control module 23 proceeds to step D1: the current value corresponding to the white light emitting unit 224 is adjusted according to the third luminance value L3 corresponding to the third white light beam, so that the white light emitting unit 224 generates the fourth white light beam. Here, the fourth white light beam may be measured by the light measuring device 202 to obtain a fourth luminance value L4 and a fourth chromaticity value (Xw4, Yw4) corresponding to the fourth white light beam. Next, the control module 23 proceeds to step D2: it is determined whether the fourth luminance value L4 corresponding to the fourth white light beam coincides with the third luminance value L3. Wherein, the control module 23 can adopt the following settings: when the difference between the fourth luminance value L4 and the third luminance value L3 is less than 5%, it is judged that the fourth luminance value L4 is identical to the third luminance value L3. The above-mentioned determination standard set to 5% can be changed according to the requirement, but the invention is not limited thereto.
In step D2, when the fourth luminance value L4 is determined to be consistent with the third chrominance value L3, go to step D3. On the contrary, when the fourth luminance value L4 is determined to be inconsistent with the third chrominance value L3, step D1 is performed again to adjust the current value of the white light emitting unit 224 again until the fourth luminance value L4 of the fourth white light beam generated after adjustment is consistent with the third luminance value L3.
After the step D2 is completed, and the fourth luminance value L4 and the third luminance value L3 are consistent, the control module 23 obtains the current value corresponding to the white light emitting unit 224 as the second adjustment parameter, i.e., performs the step D3. After steps C and D, the control module 23 obtains the first adjustment parameter and the second adjustment parameter, and combines them into a current ratio between the current value corresponding to the red light emitting unit 221, the current value corresponding to the green light emitting unit 222, the current value corresponding to the blue light emitting unit 223, and the current value corresponding to the white light emitting unit 224. Finally, the control module 23 can control the color light emitting device 23 to generate a mixed light beam according to the current ratio, and perform a gray-scale color-mixing procedure on the mixed light beam, i.e., perform step E. The method is completed. The gray level toning process is well known to those skilled in the art, and therefore will not be described in detail.
As can be seen from the above, the input device with color adjustment function and the color adjustment method of the color light emitting element according to the present invention can compare the first white light beam generated by the red light emitting unit, the green light emitting unit, and the blue light emitting unit with the second white light beam generated by the white light emitting unit before performing the gray-scale toning procedure, and obtain the first adjustment parameter based on the second chromaticity value of the second white light beam. Then, a second adjustment parameter is obtained by using a third brightness value of a third white light beam generated by the adjusted red light-emitting unit, the adjusted green light-emitting unit and the adjusted blue light-emitting unit for common light mixing as a reference. Therefore, the color light-emitting element can be controlled to generate the adjusted mixed light beam by utilizing the first adjusting parameter and the second adjusting parameter. Compared with the prior art, the mixed light beam generated by the method of the invention can really improve the color difference problem of the mixed light beam after the gray scale toning procedure is carried out on the mixed light beam.
The above description is only a preferred embodiment of the present invention and is not intended to limit the claims of the present invention, so that other equivalent changes or modifications without departing from the concept disclosed in the present invention should be included in the claims of the present disclosure.
