The flash lamp generally comprises two parts, a lamp tube and a capacitor, wherein the lamp tube is a light-emitting element, and the capacitor stores the luminous energy. When the flash is fired, the capacitor begins to discharge and fires the flash. At present, a flash device 100 as shown in FIG. 1 is generally used, which includes a photosensitive element 10, an image processor 12, a comparison unit 14, a calculation unit 16, and a flash module 18. The flash module 18 generally includes a lamp tube 17 and a capacitor 19 that flashes the lamp tube 17 by discharge. The photosensitive element 10 converts the received object optical signal into an image electrical signal, and the image processor 12 receives the image electrical signal and outputs the image color before the singularity of the singularity of the singularity of the singularity έηΛ I ;. The corpse; r t tc Han father 7L i 4 receives the brightness information Y and compares the value of the brightness information Y with a predetermined standard brightness value of the comparison unit 14, when the value of the brightness information 小于 is less than a predetermined When the standard brightness value is required, the flash module needs to be turned on, and the calculation unit 16 receives the brightness information and processes the time required to turn on the flash module, and outputs it to the flash module 18 to control Its flash. Since the energy provided by the capacitor 19 for a certain period of time is related to the initial voltage of the capacitor 19, the comparison unit I 4 compares the brightness information and determines that the flash form number is required. 1010101 Page 3/18 pages 1003066739-0 1342462 100 March 01 day correction replacement page
光燈工作時，所述閃光燈之電容及燈管即開始工作，所 述演算單元16於計算開啟所述閃光燈模組18之時間内， 所述閃光燈模組18之電容1 9之電壓值已逐漸減小，然而 實際過程中未考慮所述電容19之電壓值減小，仍用演算 單元16計算前之電容之電壓值計算得出閃光時間。當所 述閃光燈模组1 8按所計算之時間來進行閃光補償亮度時 ，由於所述電容19之電壓值減小，所述電容19於所計算 之時間内不能提供給燈管17足夠之能量，從而不能提供 物體成像所需之亮度。 【發明内容】 有繁於此，有必要提供一 閃光燈控制系統及方法。When the light lamp is working, the capacitance of the flash lamp and the lamp tube start to work, and the calculation unit 16 calculates the voltage value of the capacitance of the flash module 18 gradually after the calculation of the flash module 18 is started. However, in the actual process, the voltage value of the capacitor 19 is not considered to be reduced, and the flash time is calculated by using the voltage value of the capacitor before the calculation unit 16 calculates. When the flash module 18 performs flash compensation brightness according to the calculated time, since the voltage value of the capacitor 19 is decreased, the capacitor 19 cannot provide sufficient energy to the lamp tube 17 in the calculated time. Therefore, the brightness required for imaging the object cannot be provided. SUMMARY OF THE INVENTION There is a need to provide a flash control system and method.

The distance between the fixed photosensor and the flash lamp and the discharge time are assumed to be the test points before the effective distance of the flash, the capacitors being at different voltages. The light tube of the flash module is fired, and the light intensity of the flash module is measured by a light sensor. The test result is obtained by the experimental test result 096122528 Form No. 1010101 Page 9/18 pages 1003066739-0 1342462 Correction replacement page of March 01, 100, in step S600, the second time when the flash module 29 is flashed The flashing module 29, the triggering unit 292 of the flashing module 29 receives the second time value of the flashing of the flashing module 29 to control the capacitor C, and discharges to excite the lamp 291 to emit light. 1 The relationship between the magnitude of the capacitor voltage and the flash intensity of the flash module. Then, the capacitor is read before the calculation unit starts calculating and the voltage value is calculated, and the image of the target image is measured by the photo sensor. The brightness is adjusted according to the relationship between the magnitude of the capacitor voltage and the flash intensity index of the flash module to achieve a predetermined brightness. The different capacitances of the capacitor need to compensate for different discharge times. Obtaining a relationship between discharge times of the capacitors to be adjusted at different voltages of the capacitors, and a capacitance discharge time to be compensated as a horizontal axis, wherein the capacitance is different from a voltage value before calculation is started before the calculation unit starts calculating A curve is established for the vertical axis, and then the preset formula adopted by the adjustment unit is obtained. [0037] Compared to the prior art, the flash control The system and method use the adjustment unit 28 to adjust the first time value ti calculated by the calculation unit 26 to obtain a second time value t2, and control the flash time of the flash module 29 by the second time value t2. The brightness required for imaging an object. [0038] In summary, the present invention has indeed met the requirements of the invention patent, and the patent application is filed according to law. However, the above is only a preferred embodiment of the present invention, and the present invention is The scope of the invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art to the spirit of the invention are intended to be included within the scope of the following claims. 096122528 Form No. A0101 笫10 pages/Total 18 pages 1003066739-0 1342462 Correction page of March 01, 100 [Simplified illustration] [0039] Fig. 1 is a prior art flash system. 2 is a functional block diagram of a flash control system according to an embodiment of the present invention.
