Description

The present invention relates to a photographing system.

Slow shutter (bulb photography, long exposure) is known as one of the photography methods with a camera. This photography method involves a longer exposure time than normal photography, and is used, for example, in so-called "light painting," which involves moving a penlight in a dark space and photographing the trajectory of light.

When performing light painting with a conventional shooting system, live view cannot be performed while the camera is taking long exposures, making it difficult to check whether the penlight is drawing letters or figures of the desired shape and size. There wasn't. Also, because of the long exposure, faces tended to become blurry and unclear.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIGS. 1a and 1b, a photographing system 1 according to an embodiment of the present invention is installed in a darkroom D, photographs the trajectory of light of a penlight L moved by a user, and generates a light painting image. .

As shown in FIG. 1b and FIG. 2, the photographing system 1 includes an arithmetic and control device 10, a first photographing device 11, a second photographing device 12, a touch panel 13, a printer 14, a communication device 15, etc. housed in a housing. .

The first photographing device 11 and the second photographing device 12 are, for example, digital cameras, and output photographed image data to the arithmetic and control device 10 .

The touch panel 13 displays operation buttons, and when an operation button is pressed, receives an operation instruction corresponding to the operation button. Furthermore, the touch panel 13 displays a live view image, which will be described later. Instead of the touch panel 13, a display without a touch function and input means such as a keyboard or a mouse may be provided.

The printing method of the printer 14 is not particularly limited, and an inkjet method, a sublimation type thermal transfer method, a melting type thermal transfer method, etc. can be used.

The communication device 15 can send and receive data via a network such as the Internet.

The arithmetic and control device 10 is a computer that controls each part of the imaging system 1 and exchanges data. As shown in FIG. 3, the arithmetic and control device 10 has a storage unit 100 consisting of a hard disk or a semiconductor memory. By executing the light painting image generation program stored in the storage unit 100 by the CPU of the arithmetic and control unit 10, the photographing processing unit 101, display processing unit 102, image processing unit 103, address information acquisition unit 104, and print control are performed. The functions of section 105 and transmission processing section 106 are realized. The processing of each part of the arithmetic and control device 10 will be described later.

Next, a photographing method using the photographing system 1 will be explained along the flowchart shown in FIG.

When the user enters the dark room D and operates the touch panel 13 to instruct the start of photographing processing, the photographing processing section 101 controls the first photographing device 11 to perform the first photographing (step S1). The first photographing device 11 lights up a flash, increases the shutter speed, and photographs the user with a first exposure time. By photographing with the first photographing device 11, a user image P1 as shown in FIG. 5a is generated.

The photographing processing unit 101 acquires the user image P1 from the first photographing device 11 and stores it in the storage unit 100. The user image P1 is captured by illuminating the user with flash light and increasing the shutter speed, so the user's face is clear.

If there is a lighting fixture in the darkroom D, the first photographing device 11 may photograph the user while the lighting fixture is used to brighten the inside of the darkroom D.

Next, a second photographing is started using the first photographing device 11 and the second photographing device 12 (step S2). In the second photographing, in order to photograph the trajectory of the light of the penlight L, both the first photographing device 11 and the second photographing device 12 turn off their flashes and perform photographing in a dark room D.

The photographing processing unit 101 controls the second photographing device 12, slows down the shutter speed, and sets the exposure time to a second exposure time longer than the first exposure time to perform so-called bulb photography. The second exposure time is, for example, about 10 to 30 seconds.

The photographing processing unit 101 controls the first photographing device 11 to perform photographing in live view mode. The shutter speed of the first photographing device 11 in live view mode is faster than the shutter speed of the second photographing device 12 performing bulb photography, and during the first photographing of the first photographing device 11 in step S1. The shutter speed may be faster than the shutter speed of

The photographing processing unit 101 sequentially acquires photographed images (live view images) from the first photographing device 11. The display processing unit 102 sequentially (continuously) displays the captured images sequentially acquired by the imaging processing unit 101 on the touch panel 13. As a result, a live view image is displayed on the touch panel 13 (step S3). For example, the touch panel 13 displays a live view image P4 as shown in FIG. 6 in which only the part of the penlight at the time of shooting is bright. On the live view screen of the touch panel 13, bright areas move according to the user's movements.

The user can adjust the trajectory of the penlight L while viewing the live view image displayed on the touch panel 13.

When the second photographing device 12 performs exposure for a predetermined time (step S4_Yes), a light image (light painting image) that captures the trajectory of light is generated. For example, a light image P2 as shown in FIG. 5b is generated. The photographing processing unit 101 acquires a light image from the second photographing device 12 and stores it in the storage unit 100.

The image processing unit 103 combines the user image obtained in the first shooting and the light image obtained in the second shooting to generate a composite image (step S5). For example, the image processing unit 103 adds the brightness of the user image and the light image to generate a composite image. The method of image synthesis is not particularly limited, and known methods such as alpha synthesis can be used. The composite image is stored in the storage unit 100.

For example, by combining the user image P1 shown in FIG. 5a and the light image P2 shown in FIG. 5b, a combined image P3 shown in FIG. 5c is generated.

The address information acquisition unit 104 displays an email address input screen on the touch panel 13. The user operates the email address input screen to input an email address (step S6). The address information acquisition unit 104 acquires email address information via the touch panel 13 and stores it in the storage unit 100. The e-mail address may be entered at any time, such as before the photographing process or after the printout, which will be described later.

The transmission processing unit 106 uses the communication device 15 to transmit an e-mail with the composite image data attached to the input e-mail address.

The print control unit 105 transfers the composite image to the printer 14, controls the printer 14, prints the composite image on paper, and outputs the print 3 (see FIG. 1b) (step S7).

As described above, according to the present embodiment, while the second photographing device 12 is slowing down the shutter speed and photographing the trajectory of light, it is possible to perform live view using the captured image by the first photographing device 11. can. The user can adjust the trajectory of the penlight L while viewing the live view screen, and draw characters or figures of a desired shape and size with the penlight L. In addition, since the user image is captured at a faster shutter speed in addition to the light image, the user's face can be made clear.

In the embodiment described above, the user may be requested to input an email address and respond to a questionnaire. The photographing system 1 collects the questionnaire response results.

In the above embodiment, an example was explained in which a composite image is attached to an email and sent using an input email address. A card with a passcode etc. printed thereon may be printed out from the printer 13.

The image processing unit 103 combines the user image obtained in the first shooting with the image shot in the live view mode by the first imaging device 11 in the second shooting, and displays this synthesized image as a live view image on the touch panel. 13 may be displayed.

For example, as shown in FIG. 7, a composite image P5 obtained by combining a user image P1 obtained in the first photographing and an image P4 photographed in the live view mode by the first photographing device 11 in the second photographing is a live image. displayed on the view screen.

The image processing unit 103 cumulatively adds the brightness of a plurality of images taken by the first photographing device 11 in live view mode in the second photographing, and combines the brightness cumulative addition image with the user image obtained in the first photographing. The synthesized image may be displayed on the touch panel 13 as a live view image.

For example, as shown in FIG. 8, the luminance accumulation is obtained by cumulatively adding the luminances of the user image P1 obtained in the first photographing and the plurality of images photographed in the live view mode by the first photographing device 11 in the second photographing. A composite image P7 obtained by combining the added image P6 is displayed on the live view screen.

By displaying such composite images P5 and P7 on the live view screen, the user can adjust the trajectory of the penlight in consideration of the size and position relative to his or her body.

The penlight trajectory guide may be displayed overlappingly on the live view screen. For example, before photographing, a guide input screen as shown in FIG. 9a is displayed on the touch panel 13, and a guide input is accepted from the user.

The user presses the pen button B1 and inputs hand-drawn patterns, illustrations, characters, etc. into the input area R. By pressing the text button B2, characters can be input. By pressing the template button B3, a desired image can be selected from predetermined template images and input. The template image is an image of a star, the moon, a heart, etc., and is stored in the storage unit 100 in advance.

For example, as shown in FIG. 9B, a live view image P8 is displayed on the touch panel 13, in which the user image and the hand-drawn pattern guide G1 are combined with the image photographed in the live view mode. Further, as shown in FIG. 9c, a live view image P9 is displayed on the touch panel 13, which is a composite of the user image and the text guide G2 with the image photographed in the live view mode. Further, as shown in FIG. 9D, a live view image P10 is displayed on the touch panel 13, which is a composite of the user image and the guide G3 of the template with the image photographed in the live view mode.

The user can create a desired light image by moving the penlight in accordance with the guides G1 to G3 while viewing the live view screen.

In the second photographing, the first photographing device 11 may perform bulb photographing, and the second photographing device 12 may perform photographing in live view mode.

In order to prevent the user from being reflected in the light image due to the light from the live view screen of the touch panel 13 during the second shooting, the brightness of the user image may be lowered and displayed in live view. Furthermore, the live view display may be performed by lowering the brightness of the left and right sides of the user image compared to the central part where the user is shown.

The user image may be captured after the ride image is captured while the live view screen is displayed.

It should be noted that the present invention is not limited to the above-described embodiments as they are, but can be implemented by modifying the constituent elements within the scope of the invention at the implementation stage. Moreover, various inventions can be formed by appropriately combining the plurality of components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiments. Furthermore, components of different embodiments may be combined as appropriate.
