Definitions

• This invention concerns an automatic photo-seal dispenser, of the sort that one might find in an entertainment facility such as a game center, which dispenses a photo-seal.
• a photo-seal is a printed seal of an image captured by a digital camera and printed by a color printer.
• the automatic photo-seal dispenser according to this invention is usually installed in a photo booth.
• automatic photo-seal dispensers which are installed in entertainment facilities such as game centers, as mentioned above, use fluorescent or incandescent light as their illumination means when photographing the subject with a digital camera.
• the illumination is required continuously until the photograph is taken since the person to be photographed needs enough time to consider poses as his image is displayed on a monitor. Because of this reason, a fluorescent or incandescent light is usually used as the light source for the photograph.
• the brightness of the image to be printed must be corrected by software processing. Because the customer is unfamiliar with the processing which is needed, he will not easily be able to choose the optimal illumination level. Even though, as has been described, the brightness of the photo-seal can be corrected by a processing routine, the monitoring image on the monitor when the customer considers the pose and the actual print image which is actually photographed for printing a photo-seal are radically different. There is a demand, then, that the state of illumination when the customer considers the pose is the same one used when the image is actually taken.
• strobe light from a stroboscopic illumination unit is used only when the photo is actually taken, there is no light when the customer is considering a pose before taking the photo. This makes it difficult to consider a pose.
• the objective of this invention is to provide an automatic photo-seal dispenser with the following characteristics. It will provide optically uniform conditions throughout the entire region in the photo booth, comprising the space in which a number of peo ⁇ ple can pose and the visual field of the camera. Because it has a brightness adjustment means to adjust the brightness of the camera's output image, it will enable the image which the customer sees when he is considering a pose to match the actual image that will actually be photographed and photo-sealed, even when the subject is lit by auxiliary (supplementary) lighting. It will be able to capture the optimal image to produce a high-quality photo-seal even when the quantity of strobe illumination gets lower. If the quantity of strobe illumination gets lower, it will detect this status in order to achieve the optimal image.
• the photo- seal dispenser according to this invention installed in a photo booth has: a coin processing means to detect and process coins which are inserted; an input means to input an operating command; a first illumination means to illuminate the booth and an image, which continuously illuminates the subject of the photograph in a photo booth; a second illumination means, which illuminates the subject of the photograph while the print image is being captured; a camera which captures the image of the subject to be photographed; a display means to display the image or necessary information; a printer, which prints and outputs a photo-seal of the person or persons whose image was captured; and a control means to control these essential components.
• This photo-seal dispenser in a photo booth works in the following fashion: when the customer inserts a coin, an operating command is input by the customer, the person or persons are illuminated by the first and second illumination means of illumination, and the camera captures their image. The image which is captured is displayed on the display means, and then a photo-seal is printed and output by the printer.
• the second illumination means to illuminate the subject of the photograph, has a strobe box which illuminates the region to be photographed by means of a stroboscopic illumination unit contained in a box-like enclosure, a reflector panel which reflects the strobe light emitted by the device into the region to be photographed, and a diffusion panel which diffuses the strobe light into the region to be photographed.
• the first illumination means includes commonly used lighting devices such as ordinary fluorescent or incandescent lamps, or it may include a combination of one of these with a strobe light. Such a combination may also be used as the auxiliary light source (supplementary illumination 9) .
• the camera includes digital cameras and digital video cameras.
• the diffusion panel for the strobe box may consist of more than one panel.
• two of the strobe boxes may be placed symmetrically to the left and right of the camera.
• the direction of the second illumination means may be selected so that a portion of the illumination from the strobe boxes on either side of the camera overlaps in the region to be photographed.
• the second illumination means may be provided above the region to be photographed which lights the subject from above.
• a brightness adjustment means may be provided to adjust the overall brightness of the image output by the camera.
• This brightness adjustment means to adjust the brightness would adjust the brightness of the displayed image output on the display means and match that to the brightness level of the image that actually printed on the photo- seal so that there would be no discrepancy between the appearance of the image when the pose is approved on the display means and that when the image is actually printed as a photo-seal.
• the brightness adjustment means would also adjust the brightness of the photo-seal to an appropriate level when the quantity of strobe light is detected as insufficient at the moment the photo is taken.
• a service life detecting means may be provided to detect the service life of the stroboscopic illumination unit in the strobe box.
• the service life detecting means to detect the service life may consist of a counter which counts the number of times the strobe flashes and a comparing means to determine service life by comparing the number of flashes with a given number which predicts the service life.
• the service life detecting means to detect the service life may alternatively consist of a light sensor which receives the strobe light and outputs a signal according to the quantity of light received, and a comparing means which compares this output signal representing the quantity of light with a given value for quantity of light which was set to determine the service life.
• the second illumination means which lights the subject for the print image (i.e., the image which will become the photo-seal)
• a dedicated strobe box with a stroboscopic illumination unit, a reflector panel and a diffusion panel. This allows a uniform beam with a sufficient quantity of light to be produced.
• This device is much smaller than the umbrella-type reflectors normally used in studios, so automatic photo booths that use this dedicated strobe box can be made more compact and cheaper.
• the equipment requires a smaller space, so it can fit into a smaller area.
• the strobe box emits a sufficient quantity of light in a uniform beam. As a result, a number of people can pose in the photographic space which is the visual field of the camera.
• the strobe box provides optical conditions in that field characterized by a sufficient quantity of light which is uniform throughout the field. It eliminates shadows caused by extended fingers or by one person shadowing another, so that a high- quality photo-seal can be produced.
• the second illumination means is provided in the higher position and -the illumination beam is emitted to the subject from overhead, the emitted light is scattered by the subject's hair producing a stereoscopic effect in the photograph. As a result, the photo-seal which is printed will reproduce the quality of the subject's hair in a highly satisfactory manner.
• the brightness adjustment means to change the brightness will adjust the image before it is output by the display means so that its brightness can match the brightness of the actually printed photo- seal.
• This system makes it easy to visually verify one's image, so it achieves a photographic result which is highly satisfying.
• this improvement reduces the probability that the photo will have to be retaken, it shortens the time that the customer will have to wait. It improves customer efficiency and so, from the point of view of game room management, allows earnings to be increased. Even if the quantity of strobe light should decrease, the brightness adjustment means to change the brightness can adjust the brightness to the appropriate level and produce a high-quality photo-seal .

• Control device 30 might, for example, consist of a CPU to process calculation and control routines, a ROM to store the programs and a RAM to store data needed for operations. It would then drive all these circuit devices.
• Stroboscopic illumination unit 22 lights up the stroboscopic lamp 22a when it receives input in the form of a strobe start-up signal .
• Digital cameras 11 consist of camera 11a, which, as mentioned above, photographs the subject's upper body or face, and camera lib, which photographs his entire body. When the customer indicates which camera he wishes to use, the photographic operation is begun. When a shutter signal is input to the chosen camera, it takes a photograph and outputs the signals (i.e., the image data) representing the photographed image.

• the brightness can be changed in two ways.
• the customer can input the change he desires or control device 30 can adjust the brightness of the image automatically. If the brightness is adjusted automatically, it can be adjusted to the brightness as it appeared on the display at the moment the customer selected the pose, when the booth was illuminated by fluorescent lights 16 and 18 (darker than with the strobe lights lit) , or to the brightness at the moment the strobe lights flashed.
• the brightness adjustment would be executed by increasing or decreasing the tonal values of the original image.
• the brightness of the original image might be enhanced by increasing its tonal values by ten.

• a reference value for tone is selected (for example, the brightness at the moment the image is printed) .
• the tonal values of the images are compared with this reference value. If the tone value of the captured image is inadequate when compared to the reference value, the tone of the image is adjusted.
• One of the reasons that the tonal value of a printed image will be darker than it should is that the quantity of light emitted by stroboscopic lamp 22a is decreasing. Thus monitoring the brightness of the image in terms of its tonal value allows to monitor the service life of lamp 22a as well.

• the function of the service life detecting means 35 that of monitoring the service life of the strobe, consists of detecting the signal that the lighting capability is decreasing because an insufficient quantity of light is being emitted by stroboscopic lamp 22a of illumination device 22. For this reason the quality which has been specified for the photo-seal (for example, excellent quality) may not be maintained. This circumstance can be viewed as indicating that the service life of the strobe has been completed, and a signal representing detection is output.
• the end of strobe lamp 22 's service life can be detected using three methods. One is to use an accumulator circuit to count the number of times it flashes.
• a second method is to stipulate the quantity of light which should be emitted by lamp 22 and compare the quantity of light emitted when the photo is taken with this stipulated quantity.
• a third method is to check the tone of the RGB values for the overall brightness of the image. In this embodiment, an accumulator circuit counts the flashes.
• service life detecting means 35 having the ability to detect the end of the strobe's service life, makes use of a counter which tabulates the number of times the strobe flashes.

If the sensor value is below the warning value, it outputs a signal to indicate that the user should be warned to replace the strobe.
• a message is delivered via display 12 so that the user will know he needs to find a replacement for the strobe (Step n25) , for example, "The strobe is nearing the end of its predicted service life. Please find a replacement.” When he reads this display, the customer will notify the clerk that he needs to find a new strobe
• service life detection means 35 can detect the quantity of light emitted by the strobe and monitor its service life.
