Here, the imaging unit 8 and the projection unit 14 are arranged such that the shooting direction by the imaging unit 8 and the projection direction by the projection unit 14 face the same direction. Further, the imaging unit 8 and the projection unit 14 are arranged close to each other. This makes it possible to project a moving image based on the moving image pattern from the projection unit 14 within the shooting angle of view by the imaging unit 8.

Next, referring to the flowchart shown in FIG. 2, the camera 2 according to the first embodiment of the present invention.
The shooting process will be described. When the operator operates the mode setting button of the operation unit 18 to shift the camera 2 to the moving image shooting mode, the control unit 4 stores in advance a screen for selecting a moving image pattern to be projected by the operator, that is, the memory 10. A list of names of the plurality of moving image pattern data displayed is displayed on the LCD display unit 16. For example, a list of names such as “water wave swaying”, “water wave swaying”, “mirror ball”, “candle light swaying”, “shade swaying”, “steaming up”, etc. Is displayed. When the operator moves the cursor indicating the selection target by operating the cross button and the OK button and selects “Swing of the water surface wave” from the list of names (step S10), the control unit 4 causes the projection unit 14 to “ A moving image based on the moving image pattern of “water wave flickering” is projected (step S12). In this case, the imaging unit 8 captures a subject at a predetermined frame rate, and the imaging unit 8
A through image is displayed on the LCD display unit 16 based on the photographing signal output from the.

Therefore, as shown in FIG. 3, when there is an object (ship) 42 placed on the desk W within the shooting angle of view of the imaging unit 8 of the camera 2, a moving image of “water wave fluctuation” A moving image 44 based on the pattern is projected from the projection unit 14 within a shooting angle of view of the imaging unit 8. As a result, it is possible to provide an effect such that the ship 42 floats on the water surface in the captured moving image.

The control unit 4 determines whether or not the moving image pattern change button has been pressed (step S1).
4) When the moving image pattern change button is pressed (step S14, Yes), as in step S10, a list of names of moving image pattern data is displayed on the LCD display unit 16 and projected to the operator again. The moving image pattern to be selected is selected (step S16). When the operator moves the cursor indicating the selection target by operating the cross button and the OK button and selects “Shake Waves from Underwater” from the list of names, the control unit 4 returns to step S12 and performs the projection unit 14. A moving image based on the moving image pattern of “underwater wave flickering” is projected (step S12). Therefore, as shown in FIG. 4, when an object (doll) 52 placed in a transparent box 50 exists within the shooting angle of view of the imaging unit 8 of the camera 2, A moving image 54 based on the moving image pattern of “Swing” is projected from the projection unit 14 within a shooting angle of view of the imaging unit 8. Here, the moving image 54 is also projected on the side of the box 50. Therefore, it is possible to give a production effect that the object 52 is placed in the aquarium on the moving image to be photographed.

If the moving image pattern change button is not pressed in step S14, it is determined whether or not the shooting start button is pressed (step S18). When the shooting start button is pressed (step S18, Yes), moving image shooting is started by the imaging unit 8 while the moving image is projected by the projection unit 14 (step S20). The moving image data captured here is stored in the memory 10.

The control unit 4 determines whether or not the moving image pattern change button has been pressed even during the shooting of the moving image by the imaging unit 8 (step S22), and when the moving image pattern change button has been pressed (step S22). , Yes), similarly to step S10, the moving image pattern to be projected is selected again by the operator (step S24). When the operator selects “mirror ball” as a moving image pattern to be projected by operating the cross button and the OK button, the projection unit 14 projects a moving image based on the moving image pattern of “mirror ball”. Therefore, as shown in FIG. 5, when a room 60 exists within the shooting angle of view of the imaging unit 8 of the camera 2, the “mirror ball”
A moving image 64 based on the moving image pattern is projected from the projection unit 14 onto the wall or floor of the room 60 within the shooting angle of view of the imaging unit 8. Here, since the moving speed of the spot light included in the moving image 64 varies depending on the wall or floor of the room 60 being projected, the moving image 3 of the room 60 is included in the captured moving image.
It is possible to provide a production effect that makes it easy to grasp a dimensional space. This makes it possible to change the effect that is given to the captured moving image during shooting of the moving image.

If the moving image pattern change button is not pressed in step S22, it is determined whether or not the shooting end button is pressed (step S26). If the shooting end button is pressed (step S26, Yes), the moving image shooting by the imaging unit 8 is ended (step S28). Then, the moving image data stored in the memory 10 is stored in the memory card 12. Also, the projection of the moving image pattern by the projection unit 14 is finished (step S).
30).

According to the camera of the first embodiment of the present invention, it is possible to perform moving image shooting by the imaging unit while projecting a moving image based on the moving image pattern from the projection unit within the shooting angle of view by the imaging unit. Thus, it is possible to easily obtain moving image data having a high effect.

Next, a camera according to a second embodiment of the present invention will be described.

Therefore, a detailed description of the same configuration as that of the first embodiment will be omitted, and description will be made using the same reference numerals as those of the first embodiment.

FIG. 6 is a flowchart for describing shooting processing of the camera 2 according to the second embodiment. When the operator operates the mode setting button of the operation unit 18 to shift the camera 2 to the still image shooting mode, the control unit 4 sets names of a plurality of moving image pattern data stored in advance in the memory 10. A list is displayed on the LCD display unit 16. When the operator moves the cursor indicating the selection target by operating the cross button and the OK button, and selects, for example, “Swing of underwater waves” as a moving image pattern to be projected from the list of names (step S40), the control unit 4 determines whether or not the release button is half-pressed (step S).
42). In this case, the imaging unit 8 captures a subject at a predetermined frame rate, and displays a through image on the LCD display unit 16 based on the imaging signal output from the imaging unit 8.

When the release button is half-pressed (Step S42, Yes), the control unit 4 projects the projection unit 1.
4 starts projection of a moving image based on the moving image pattern of “underwater wave flickering” (step S44). Therefore, as shown in FIG. 4, a moving image 54 representing the wave of underwater waves is projected from the projection unit 14 onto, for example, a transparent box 50 on which the object 52 is placed.

The control unit 4 determines whether or not the release button is half-pressed (step S4).
6) If the half-press of the release button is released (step S46, Yes), the process returns to step S40 to stop the projection of the moving image and cause the operator to select the moving image pattern to be projected again. On the other hand, if the release button is not half-pressed (step S46, No) and the release button is fully pressed (step S48, Yes), the projection unit 14 causes the moving image 5 to be displayed.
In the state where 4 is projected, a still image is taken by the imaging unit 8 (step S50), and still image data based on the taken image is stored in the memory card 12. The projection unit 14
The moving image projection by is terminated (step S52).

According to the camera of the second embodiment of the present invention, it is possible to shoot a still image of a subject by the imaging unit while projecting a moving image from the projection unit within the shooting angle of view by the imaging unit.

For example, as shown in FIG. 7A, when the ladybug 40 moving on the desk W exists within the shooting angle of view of the imaging unit 8 of the camera 2, the control unit 4 temporarily stores in the memory 10. The ladybug 70 is recognized as the main subject on the basis of the image data of the through image output from the image pickup unit 8 stored in the memory. In this case, since the ladybug 70 is moving, the ladybug 70 is tracked on the basis of the image data of the through image, and a moving image is projected such that a spotlight 72 having a white color and a predetermined luminance is applied to the ladybug 70. You may make it perform. That is, FIG.
As shown in (d), a moving image including a spotlight 72 that tracks the ladybug 70 is projected from the projection unit 14. Thereby, it is possible to provide an effect such that the spotlight 72 hits the moving ladybug 70 on the moving image to be shot.

Further, when a human face exists within the shooting angle of view of the imaging unit 8 of the camera 2, the control unit 4 performs face recognition based on the image data of the through image stored in the memory 10. The moving image to be projected may be determined from the projection unit 14 based on the facial expression of the person recognized by recognizing the face as the main subject and performing smile recognition or the like. For example, when the facial expression of a person is a smile, it may be determined as a moving image that brightens the background of the person within the shooting angle of view.
