The following diagrams are combined to explain the content in detail with examples. First Embodiment: FIG. 2 is a schematic front view of the appearance of the camera in the first embodiment. As shown in the figure, 'in this embodiment' the body 1 has an infrared transmitter 20 and an infrared receiver 21 on the front side (the same side as the lens 3 and the viewing window 2), and the rear side of the body i has Shielding warning light 22. The infrared transmitter 20 and the infrared receiver 21 are placed on the outer side of the edge of the sharp light lamp 10 'to monitor the presence of a shield. After the user activates the flash function, the infrared transmitter 20 will consistently emit an infrared-type test signal 'and the infrared receiver 21 will wait to receive the test signal while reading. When there is no obstruction (such as the user's hand) near the flash 10, the infrared test signal emitted by the infrared transmitter 20 will be sent to the outside without encountering reflection, so the infrared receiver 2 丨 does not No signal will be received. On the other hand, when the user's hand or other obstruction is placed directly in front of the flash or within the flash angle range, the infrared test signal will be reflected, and the infrared receiver 21 can receive the reflected test letter saying , As shown in Figure 3. #Infrared receiver 21 When it receives the test signal reflected by the shield 302, it will generate a warning signal for other actions: f is a controlled action. In addition, 'in this embodiment, because the infrared transceiver is a general commercial product', infrared detection is used, but it is not intended to limit the present invention. For those who are familiar with wireless transmission technology, 4390 1 1 V. Description of the invention (6 ) You can also use various other types of radio waves for detection, to achieve the same purpose. In addition, some commercial products also have an infrared transmitter and an infrared receiver assembled into the same electronic component, which can also be applied to the present invention. When a shield 30 appears in front of the flash 10, two coping methods are adopted in this embodiment, as shown in FIG. Fig. 4 shows a circuit diagram of a camera flash detection device in the first embodiment. The first masking method is to use the mask & warning light 22 to achieve the purpose of warning. The shielding warning light 22 can be achieved by a light-emitting diode (LED). When the infrared receiver 21 receives the reflected infrared test signal, a warning signal is generated and sent to the shielding warning light 22 Let the light-emitting diode emit light. Since the warning light M is placed on the back of the fuselage 1, the user can judge whether there is an obstruction blocking the flash by checking whether the warning light 22 is turned on, and then decide whether to continue recording. V 'shown in the figure. The sub-control switch 25 indicates no state, and the sign indicates the state. If a masking method is used, the user is prohibited from recording. As in the fourth, an electric switch 25 is installed on the path from the shutter knob 5 to the camera's internal shutter (can be implemented by using a MOS transistor, for example), and the switching state of the electric control is controlled by a warning signal. The electronic control switch 25 will be driven when the external signal of the warning signal is displayed. The road-shaped user can control the shutter through the shutter knob 5; when there is a hidden object, the electronic control switch g25 will be driven to display ^ The user cannot achieve the purpose of control through the gate knob 5 here. It is forbidden to shoot through the transparent material. The person who does not care about covering the warning light 22 message is not allowed. One person can prevent flashing.

Description of the invention (7) Photographing with incomplete light. Fig. 5 is a flowchart showing a camera flash detection method in the first embodiment. First, when the user activates the flash function (S1), the infrared transmitter 20 starts to emit an infrared test signal (S2). At the same time, the infrared receiver 21 waits to receive the reflected infrared test signal (S3). If the infrared receiver 21 consistently receives the reflected infrared test signal, the warning signal 22 is used to light the warning light 22 and the user is prohibited from pressing the shutter (S4) until the shield in front of the flashlight 10 is removed. If the infrared receiver 21 does not receive the infrared test signal (that is, there is no obstruction in front of the flashlight 10), it is determined whether the user presses the L-shaped door knob (g &). If the user presses it, the flash 10 is caused to fire and shooting is completed (S 6). During the activation of the flash function, the 'infrared transmitter 2 q and 纟 τ outside receiver 21 1 will continue to transmit and wait for reception to prevent any obscuration from blocking the flash 10. . In the first embodiment, the 'infrared transmitter 20 and infrared receiver 2 i can detect the presence of a cover immediately when the flash function is activated; when the cover appears, a warning light can be used to inform the user of the benefits and 'Stop pressing the shutter', so as to actively prevent image capturing under uneven flash conditions, and achieve the object of the present invention. Second embodiment: In the first embodiment, only one set of infrared emitters / receivers located under the flash's edge is used to detect the obstructions in front of the flash.

Description of the invention (8) Occlusions can occur, for example, the obstructions only appear above the edge of the flash, and they cannot be detected effectively at this time. In this embodiment, an array of infrared emitters / receivers is used to detect obstructions to improve the accuracy of detection. FIG. 6 is a schematic front view showing the appearance of the camera in the second embodiment. As shown in the figure, four infrared emitters / receivers are set around the edge of the flash 10. Among them, 'infrared transmitter 20a / receiver 21a is placed below the edge of the flash 10, and infrared transmitter 20b / receiver 2lb is placed to the right of the edge of the flash 10' Above the edge, the infrared emitter 20d / receiver 21d is placed to the left of the edge of the flash 10. With these four IR transmitters / receivers, the presence of obstructions can be detected more reliably. Fig. 7 shows a circuit diagram of a camera flash detection device in the second embodiment. As shown in the figure, the warning signals generated by the infrared receivers (2 1 a-2 1 d) pass through one infrared 2 2. On the other hand, the electric infrared receiving between the shutters cannot control the shutter. In this embodiment, due to the detection of the shielding object in this embodiment, although the present invention passes through the gate or the 2 9 receiver detects, each warning sub-control opener detects the action. Tak can achieve multiple utilizations, so the detection is based on a better Shida judgment. That is, as long as any obstruction is detected, the obstruction warning light signal is controlled to be connected in series with the shutter knob 5 and off 2 5 a ~ 2 5 dd. Similarly, as long as any obstruction is left, this path is left open and the user To the purpose of active control. The same purpose as the first embodiment. In addition, the reliability of the group of infrared transmitters / receivers is more improved = 'The embodiment is disclosed as above', but it is not intended to limit
