Referring to Figures 1, 3 and 4 together, the drive element 23 is a motor in the present embodiment, preferably a stepper motor. The driving member 23 includes a rotating shaft 231 which is freely rotatable 360 degrees, and one end of the rotating shaft 231 is fixed to the center of the color wheel 21. The drive control circuit 22 controls the operation of the drive unit 23, and the operation of the drive member 23 causes the rotary shaft 231 to rotate to drive the color wheel 21 to rotate accordingly. A positioning mark 231 is disposed on the rotating shaft 231. The positioning sensor 60 is configured to identify the positioning mark Μ and output a positioning signal Υ4 according to the positioning mark ,. The processing module 30 is driven by the driving control circuit according to the positioning signal Υ4. 22 and the drive element 23 position the color wheel 21. The positioning sensor 60 includes two diodes 与 1 and 02. In this embodiment, the diode Di is a light-emitting diode, and is applied to the diode Di, and the voltage is applied to cause the diode Di to emit light; the diode D2 is a photodiode. The two poles 1 > 2 can absorb light to generate current. The incident light ray emitted from the diode Di of the positioning sensor 60 is irradiated on the positioning mark ,, and the reflected light L2 is reflected by the positioning target M to be reflected on the diode 〇2, thereby causing the diode The output of the 〇2 is fluctuated such that the output of the diode D2 forms the localization signal 丫4°. The diode 01 and the diode D2 are symmetrically distributed in the incident ray and the normal L3 of the reflected ray L2. On both sides. It is further explained that the positioning mark Μ is the same as the texture of the driving element 23, and the intensity of the light reflected on the diode D2 is different. Therefore, the positioning sensor 6 is rotated every time the driving element 23 rotates. Then, a fixed-bit signal Y4 is output, and the positioning signal I is a high-frequency or low-frequency bandwidth in the output signal of the positioning sensor 6〇. In the present embodiment, the high frequency bandwidth indicates that the degree of light reflection of the positioning mark 比 is stronger than the degree of light reflection of the driving element 23. In this embodiment, the number of steps of the driving element 23 to rotate one step is 120 steps, that is, the driving element 23 drives the color wheel 21 to rotate one turn and needs to rotate 12 steps, then each coating color segment of the color wheel 21 is changed. The drive element 23 is required to be rotated by 30 steps. Initially, the positioning mark 设为 is set as the first step, and the corresponding position of the first step is a white film color segment, then it can be determined that the number of steps corresponding to the position of the red coating color segment is the 31st step, according to this The analogy can be used to determine the number of initial steps in the green coating color segment corresponding to the blue coating color segment. Referring to FIG. 1 again, the tone selection module 4 outputs a tone signal 丫1 corresponding to the tone to the processing module 3 according to the color tone selected by the user. It can be understood that the color selection module 40 is a programming interface (not shown) provided with a plurality of color tone options, and the user can select the desired color tone by the program interface. The processing module 3 receives the tone signal 丫1, and outputs a first control signal 根据2 to the positioning sensor 60 and a second control signal to the driving control circuit of the color wheel module 2〇 according to the tone signal Υι twenty two. The positioning sensor 60 receives the first control signal γ2, and starts detecting the rotating shaft 231 of the driving component 23 according to the first control signal γ2, and immediately returns the positioning signal Υ4 to the processing module 3〇. The driving control circuit 22 receives the second control signal Υ3, and outputs a rotational driving signal 9 200952460, No. Y5 to the driving element 23 according to the second control signal Υ3. The driving component 23 receives the rotational driving signal . . . , and rotates the rotating shaft 231 according to the rotational driving signal Υ5. During the rotation, the positioning sensor 60 continuously detects the rotation of the rotating shaft 231 and immediately returns the positioning signal Υ4 to the processing module 3〇. When the positioning signal γ4 appears to be pulsating, the processing module 3 determines that the color wheel 21 is in the white coating color segment and determines the number of steps of the color wheel 21 to the desired coating color segment. When the color wheel 21 is turned to the desired key film color segment, the processing module 3 〇 again outputs a third control signal γ'3 to the drive control circuit 22. The driving control circuit 22 receives the third control signal γ3, and sends an interrupt signal Υ 5 to the driving component 23 according to the third control signal γ3. The driving component 23 stops the rotating shaft 231 according to the interrupt signal Υ5. Rotating, thereby forcing the color wheel 21 to stop rotating, so that the desired film color segment is clamped on the light path of the flash lamp 14. It can be understood that, in order to save energy, at this time, the processing module 3 can send a signal to turn off the operation of the positioning transmission 60. . After changing to the desired hue, the shooting module 50 outputs a shooting signal to the processing module 3〇. It can be understood that the shooting module 5 can be a shutter button (not shown), and the user can press the shutter button to cause the shooting module 50 to output the shooting signal %. The processing module 3 outputs a trigger control signal to the flash trigger circuit 16 according to the shooting signal Υ6, and the read flash trigger circuit 16 outputs a flash trigger signal Ys to the flash 14 according to the trigger control signal Υ7, the flash 14 The light is emitted according to the flash trigger signal Ys. The light emitted from the flash lamp 14 is irradiated from the image forming apparatus 100 through the desired coating color section of the color wheel 21 to immerse the photographed image with a desired color tone. 200952460 The light image of the embodiment 3 is provided by setting the color wheel 21 on the flash to make the flash 14 emit one of the coated color segments, so that the flash 14 can be seen in a wide range of colors. (4), can change the color of the shooting picture. Further, the image forming apparatus 100 is rotated by the (4) color wheel 21 by the frame member 23, and the color wheel 21 is automatically positioned by the positioning sensor (10). k Referring to Fig. 5, an image forming apparatus 200 is provided in accordance with a second embodiment of the present invention. The imaging device of the embodiment of the present invention is different from the imaging device 100 of the first embodiment in that the imaging device 2 further includes a flash light exit port 24, a first surface 80 having the flash light exit port 24, and a The first surface 8 is adjacent to the second surface 9A and an operation window 25 is formed on the second surface 90. A coating color segment of the color wheel 21a can be seen through the flash light exit port 24. A uniformly distributed gear 211 is disposed on the circumference of the color wheel 21a, and the user can toggle the gear 211 by the operation window 25 to rotate the color wheel 2la ©. When the red coating color segment of the color wheel 21a is required, the gear wheel 211 is moved by the operation window, and the color wheel 21& is rotated, so that the coating color segment displayed by the flash light exit port 24 is a red coating color segment. . The light from the flash Ua can be emitted from the flash exit port 24 through the red coating color segment of the color wheel 21a. Further, the imaging device 200 may not be provided with the color tone selection module 40, the positioning sensor 60, the drive control circuit 22 11 200952460, and the driving component 23' of the imaging device 100, and may be configured to realize automatic and manual bidirectional selection. The color of the picture. In the present embodiment, only the hue of the shooting screen - is selected manually. The image forming apparatus 2 provided by the second embodiment of the present invention has the structure of the image forming apparatus 100 provided by the first embodiment, which enables the flash unit 14a to have a wide range of light filling, and can change the color tone of the captured image, and has a structure.
