The shooting position specifying module 102 is used to circle and select a shooting position on the display interface 100 of the image capture device 10, that is, the position where the subject is expected to be located in the frame range presented by the entire display interface 100; and the image recognition module 104 is used to identify a display position when the image of the subject is actually displayed on the display interface 100; the comparison processing unit 106 is based on the shooting position circled by the shooting position specifying module 102 and the display position identified by the image recognition module 104 Compare, compare whether there is a position gap between the two, and generate a control signal according to the compared position gap, this control signal is used to indicate a movement direction required to compensate the position gap; the indicating unit 108 is based on The control of the control signal outputs a notification message, so that the subject moves according to the moving direction notified by the notification message, so as to adjust the display position presented on the display interface 100, so that the subject's image can finally be displayed in the circled area. on the shooting position.

When the comparison processing unit 106 compares the displayed position of the person being photographed with the photographing position and judges that there is no position gap, that is, the displayed position of the photographed person is already at the predetermined photographing position, unless a control signal is issued to control the instruction unit 108 to output a notification information, so that the person being photographed knows that he is outside the predetermined shooting position, and transmits an activation signal to control the automatic shooting module 110 to carry out the actual shooting action.

The image capturing device 10 of this embodiment can be a digital camera or a mobile communication device with a camera function. Next, a digital camera is taken as an example, and the schematic diagrams shown in FIG. 2 and FIG. 3 provided by the present invention are further described. FIG. 2A is a schematic diagram of a digital camera 10a. The indicating unit 108 of the digital camera 10a is a light-emitting element 1082 arranged on the surface of the image capture device 10 (that is, the surface of the digital camera 10a), respectively used to instruct the subject 1044 to move forward. , backward, left or right, and FIG. 3 shows a schematic view of the display interface 100 of the digital camera 10a. As shown in FIG. The shooting location specifying module 102 selects a shooting location 1022 according to the needs of the user (generally, the subject 1044). For example, when the display screen 1002 is a touch screen, directly click Click on 1002 to circle a specific range, and record it as the predetermined shooting position 1022 by the shooting position designation module 102; or provide the function of dividing the display screen 1002 into multiple blocks, through the shooting position designation module 102 The range surrounded by the selected blocks is recorded as the shooting position 1022 .

The subject 1044 is located in front of the lens of the digital camera 10a, and the image received by the lens is displayed on the display screen 1002 (as shown in FIG. 3B ). The image recognition module 104 recognizes the image of the subject 1044 displayed on the display screen 1002 Location 1042. Since the image recognition technology currently used on the digital camera 10a is very developed and proficient, those skilled in the art can use various image recognition software and hardware dynamic detection to achieve the result of recognizing the above-mentioned display position 1042 , which will not be repeated here.

The comparison processing unit 106, such as a digital signal processor (DSP), compares the shooting position 1022 circled by the shooting position specifying module 102 with the display position 1042 identified by the image recognition module 104, and compares the difference between the two. The existing position gap, as shown in FIG. 3B , is known that the display position 1042 where the subject 1044 is located is too far to the left relative to the shooting position 1022 (too far to the right from the angle of facing the camera), and thus produces A control signal is sent to the indicating unit 108 to indicate a moving direction required for compensating the position gap, that is, based on the shooting position 1022, the direction in which the display position 1042 approaches the shooting position 1022 is used to control the indicating unit 108 with the control signal Output a corresponding notification message to notify the subject 1044 to move to the left facing the camera. For example, as shown in FIG. The direction of the location 1022 moves, for example, the light-emitting element on the left side flickers to indicate that the subject 1044 moves to the left or similar indications.

The voice information in the memory (not shown) of the digital camera 10b directly prompts the subject 1044 to move in a specific direction by voice. In addition, the method of outputting the notification information by flickering the light emitting element 1082 is not limited to a plurality of light emitting elements 1082. Those skilled in the art can use a single light emitting element, Or light-emitting elements plus voice prompts and other ways to make appropriate changes.

When the subject 1044 moves its location according to the notification information output by the instruction unit 108, the comparison processing unit 106 finds that the displayed position 1042 of the subject 1044 has been located on the predetermined shooting position 1022 after comparison (as shown in FIG. 3E ) At this time, in addition to sending a control signal to control the instruction unit 108 to notify the subject 1044 that the person 1044 has been positioned (for example, the light-emitting elements 1082 for indication are all illuminated), a start signal is also sent to the automatic shooting module 110, so that the operation of automatic shooting is executed. In this way, the subject 1044 can take pictures that meet the shooting requirements and composition without the assistance of others or additional auxiliary equipment.

FIG. 4 is a flow chart of an embodiment of a method for automatically indicating a shooting position by an image capture device provided by the present invention, which includes the following steps: Select a shooting position 1022 (S401) in the upper circle; then identify a display position 1042 (S403) where an image of the subject 1044 is displayed on the display interface 100 by an image recognition module 104; then provide a comparison processing unit 106 to display The shooting position 1022 on the interface 100 is compared with the display position 1042 to determine whether there is a position gap between the two (S405); if there is a position gap between the two positions, as shown in FIG. 3B, the image of the subject 1044 If it is not located at the pre-selected shooting position 1022, the comparison processing unit 106 generates a control signal to control an indicating unit 108 (S407).
