It has been proposed that portable information terminal devices such as mobile phones, electronic organizers, PDAs (personal data accessories), etc., having a camera-capturing function be provided with a stop port light emitting means in order to improve the shooting function. I have. When mounting a camera with a tropolite on such an information terminal device, the placement position of the camera and the flashlight is greatly restricted in devices that have become smaller in recent years, such as mobile phones. However, there is a concern that red-eye phenomenon may occur when photographing a person using strobe light.

As a method to avoid the red-eye phenomenon, there is a method in which a flashlight is emitted once before shooting and the image is taken using the afterglow.However, power consumption increases in small information terminal equipment. Therefore, it is difficult to adopt it because it deteriorates the battery life.

It is well known that the condition of the occurrence of the red-eye effect occurs when the angle between the optical axis of the person to be imaged and the camera's imaging lens and between the person and the strobe light is within 2 °. It is a fact. For example, the distance required to fit a 170cm tall person in the entire frame (the distance between the camera's taking lens and the subject) is about 1.8m. , 1800mm X t an2 ° = 62.9mm It can be said that the distance D between the optical axis of the taking lens and the optical axis of the strobe must be at least 62.9 mm.

Trobo zooming is performed, and the distance between the optical axis of the lens and the optical axis of the strobe is increased to suppress the occurrence of red-eye.

Japanese Patent Application Laid-Open No. H8-626675 discloses that a strobe light emitting unit is movably provided in a film unit with a lens in order to achieve a miniaturization while avoiding a red-eye phenomenon. The center of the light-emitting part is located outside the virtual circle, which is the range where the red-eye phenomenon occurs during stop-stop shooting, and inside the virtual circle during non-stop shooting.

Japanese Patent Application Laid-Open No. Hei 9-197520 discloses that a flash light source is coated on the front surface of a strobe light emission window while preventing the occurrence of a red-eye effect without hindering downsizing of a camera body. A camera with a built-in robot is disclosed. In this camera, the strobe unit can be moved between the stowed position with respect to the camera body and the shooting position protruding from the strobe light emission window. When the robo-emitting window is opened, the strobounit moves to the shooting position, and the optical axis of the strobe light moves above the camera body and moves away from the optical axis of the subject light. You.

In these figures, the mobile phone 1 according to the first embodiment has a substantially rectangular shape, and the length (width) W of the side in the horizontal direction of the figure is shorter than the length L of the side in the vertical direction. The thickness H is smaller than the width W.

On the surface of the mobile phone 1, as shown in FIG. 1, in one area in the vertical direction, that is, in the lower area of FIG. 1, an input operation of various buttons and keys including a button for photographing is performed. The unit 2 and the mouthpiece 3 are provided.The other area in the vertical direction, that is, the upper area in FIG. A display unit 4 and a receiver 5 are provided. Further, the tip of the antenna 6 is provided so as to protrude from one side of the upper end surface of the mobile phone 1. This antenna 6 has its rod (not shown) connected to the mobile phone 1 at the time of communication or the like. It can be pulled out from the main body.

As shown in FIG. 2, the back surface of the mobile phone 1 is provided with a photographing lens 10 of a force camera at one end in the vertical direction, that is, at the center in the horizontal direction near the upper end position in FIG. The strobolite 12 is arranged at the other end in the vertical direction, that is, at the center in the horizontal direction near the lower end position in FIG. In this case, the distance D between the optical axis of the photographic lens 10 and the optical axis of the tropolite 12 is the distance between the photographic lens 10 and the astrophore 12 in the longitudinal direction of the mobile phone 1. Are arranged so that the distance between them is the longest, so that the distance is such that the occurrence of the red-eye effect can be sufficiently suppressed, that is, 62.9 mm or more.

To take a photo of the subject, set the operation buttons on the front of the mobile phone 1 to shooting mode, and point the camera's shooting lens 10 on the back of the mobile phone 1 toward the subject. While checking the subject on the LCD display 4, press the shutter button for taking a picture to take a picture.

In an environment where the Strobe Robot 12 is used, the strobe shooting mode can be set by detecting the brightness of the subject or its surroundings and automatically or manually operating the Strobe Button. Then, press the shutter button for taking a photo, and the photo is taken under the strobe light.

FIG. 3 shows the back side of the mobile phone according to the second embodiment of the present invention. The main body of the mobile phone 1 in this embodiment is substantially the same as the embodiment in FIG. 1 and has a substantially rectangular shape, and the length (width) W in the horizontal direction of the figure is The side length L is shorter than the length L, and the thickness H is more than the width W small.

The input operation unit on the surface of the mobile phone 1 (not shown), the mouthpiece, etc., and the arrangement of the liquid crystal display unit 4 and the receiver B are almost the same as in the first embodiment. The configuration of the antenna 6 on the upper end surface is also the same as in the first embodiment.

In the second embodiment, a force camera section 14 including a photographing lens 10 can protrude laterally (to the left in FIG. 3) from the upper end of one of the long sides of the substantially rectangular mobile phone 1. In addition, it is arranged so as to be able to be stored inside the main body of the mobile phone 1, that is, to be hopped up. The photographing lens 10 is disposed on the camera section 14 so as to face the back side of the mobile phone 1. Also, in order to take a picture even when the camera unit 14 is stored inside the main body of the mobile phone 1, the mobile phone 1 corresponding to the shooting lens 10 of the camera unit 14 at the time of storage is taken. A window 16 is provided on the back of the main body.

On the other hand, a strobe unit 18 including a strobe light unit 12 extends laterally (to the right in FIG. 3) from the upper end of the other side of the long side of the mobile phone 1 to a hop of the force camera unit 14. The mobile phone 1 is arranged so as to be able to protrude in a direction opposite to the up direction and to be housed inside the main body of the mobile phone 1. Like the taking lens 10, the strobe unit 12 is also arranged on the strobe unit 18 so as to face the back side of the mobile phone 1. In addition, when the strobe unit 18 is stored inside the main body of the mobile phone 1, it is possible to take a photograph of the stop port, so that the strobe unit 1 can be stored. A window 20 is provided at a position on the back surface of the main body of the mobile phone 1 corresponding to the strobe light 12 of FIG.

In the second embodiment, even when the camera unit 14 and the storage unit 18 are housed inside the main body of the mobile phone 1, the flash photography can be performed through the windows 16 and 20, respectively. It is possible. Camera section 14 and When the storopunit 18 is retracted, the distance D1 between the taking lens 10 and the strobe light 12 is set on both sides in the lateral (width) direction of the back surface of the mobile phone 1, both of which are substantially rectangular. Since they are arranged, they cannot be larger than the distance D in the first embodiment.

However, in order to prevent the occurrence of the red-eye phenomenon at the time of shooting the stop port, the camera unit 14 and the strobe unit 18 are hopped up in the left and right directions. As a result, the distance D2 between the taking lens 10 and the tropolight 12 can be made longer than the distance D1 when no hop-up is performed, and a distance that can suppress the occurrence of red-eye effect, that is, 62 , 9 mm or more. Therefore, in the second embodiment, in the flash photography, a choice is made between a case where the subject is concerned about the occurrence of the red-eye effect and a case where the subject is not concerned about the occurrence of the red-eye effect. It is possible to switch the shooting mode of the mouthpiece.

Also, at the time of flash shooting, only one of the camera unit 14 and the flash unit 18 is hopped up in the lateral direction, and the distance between the shooting lens 10 and the flash unit 12 is reduced. By photographing with the distance not longer than D2 when hopped up, but longer than D1 without hopping up both, we aimed at some degree of red-eye prevention effect. You can also shoot.

The camera section 14 and the strobe unit 18 are hopped up by pressing hop-up buttons (not shown), respectively, and the camera section 14 and the strobe unit 18 are moved. Pushing it into the main body of the mobile phone 1 will lock it to the storage position.

FIG. 4 shows the back side of the mobile phone according to the third embodiment of the present invention. The shape of the mobile phone 1 in this embodiment is also the first and second embodiments. It is almost the same as the form. The arrangement configuration of the surface (not shown) of the mobile phone 1 and the configuration of the antenna 6 on the upper end surface are the same as those in the first and second embodiments.

In the third embodiment, as in the second embodiment, the camera unit 14 including the taking lens 10 is laterally located from the upper end of one of the long sides of the substantially rectangular mobile phone 1 (the left side of FIG. 4). The strobe unit 18 including the strobe 12 is arranged from the upper end of the other side to the side (right side in FIG. 4). It is arranged so that it can protrude and can be stored inside the main body.

The third embodiment is different from the second embodiment in that the camera unit 14 including the taking lens 10 and the strobounit 18 including the strobe 12 are stored and protruded. Is also exposed to the outside of the main body of the mobile phone 1. That is, the camera unit 14 and the strobe unit 18 are arranged at the upper end of the rear surface of the substantially rectangular mobile phone 1 so as to slide horizontally in mutually opposite directions.

For this reason, the upper end of the rear surface 22 of the main body of the mobile phone 1 is provided with a rail composed of a surface whose thickness is one step lower than the rear surface 22 and the upper end surface so that these members can slide in the lateral direction. Grooves 24 are formed. Then, the camera unit 14 and the strobounit 18 are engaged with the rail groove 24, and the camera unit 14 can slide along the rail groove 24 to the left in FIG. The storage unit 18 is configured to be able to slide to the right in FIG.

When the camera unit 14 and the strobe unit 18 are in the stowed position, they are arranged so as to abut each other, and both sides thereof fit within the back surface (projection area) of the main body of the mobile phone 1. Are arranged as follows. At this time, the distance between the taking lens 10 and the strobe light 12 is As in the case of the first embodiment, the distance D cannot be larger than the distance D of the first embodiment.

In order to prevent the occurrence of red-eye phenomenon during shooting of the camera, slide the camera unit 14 and the strobounit 18 in the left and right directions, and move them both outward from the back (projection area) of the main unit. The distance D2 between the photographing lens 10 and the strobe light 12 can be made longer than the distance in the storage position by protruding the camera lens, as in the case of the second embodiment. It is also possible to set the distance such that the occurrence of the red-eye effect can be suppressed, that is, 62.9 mm or more.

Also in the third embodiment, in the flash photography, a subject in which the occurrence of the red-eye effect is not a problem is taken in the stop mouth shooting mode, and a subject in which the occurrence of the red-eye effect is not a concern is taken in the shooting mode. The shooting mode can be selectively switched between when the camera is turned on, and the flash shooting is performed with only one of the camera section 14 and the tropounit 18 sliding sideways. You can also.

In the third embodiment, the camera unit 14 and the strobe unit 18 can be directly moved by hand with respect to the main body of the mobile phone 1 without being operated by buttons or the like. it can. These are locked in the slide position and the storage position.

FIG. 5 shows the back side of the mobile phone according to the fourth embodiment of the present invention. The shape of the mobile phone 1 in the fourth embodiment is also substantially the same as that of the first to third embodiments, has a substantially rectangular shape, and the length (width) W of the side in the horizontal direction of the drawing is The length in the vertical direction is shorter than the length L, and the thickness H is smaller than the width W. The arrangement of the surface (not shown) of the mobile phone 1 and the configuration of the antenna 6 on the upper end surface are the same as those of the first and second embodiments. Further, in the fourth embodiment, as in the first embodiment, the photographing lens 10 of the camera is disposed at one end in the vertical direction, that is, at the center position near the upper end in FIG. The stroboscope 12 is disposed at the end of the shaft, that is, at the central position near the lower end in FIG. However, in the fourth embodiment, the difference from the first embodiment is that the camera's taking lens 10 is arranged in a portion forming the main housing 1 a of the mobile phone 1, The strobe light 12 is disposed on a sub-housing 1b which is vertically slidably mounted on the main housing 1a.

The main housing 1 a is a portion in which the upper half area in the vertical direction on the back side of the mobile phone 1 and most of the area on the front side are integrally formed, and the sub-housing is a part of the mobile phone 1. The lower half area on the back side and the lower end area on the front side are integrally formed. Then, a surface contact is made between the surface 26 which is lower than the rear surface 2 2 of the lower rear side of the main housing 1 a and the surface 30 which is lower than the upper surface 28 of the sub-housing. In addition, the sub-housing 1b can slide vertically within a predetermined range with respect to the main housing 1a.

Therefore, when the sub-housing 1b is not sliding with respect to the main housing 1a, the lower end of the main housing 1a and the upper end of the sub-housing 1b are in contact with each other, and The length of the telephone 1 in the vertical direction is equal to the length L of the first embodiment shown in FIG. When the sub-housing 1b is slid vertically with respect to the main housing 1a, the length of the mobile phone 1 in the vertical direction is L1, which is much longer. Accordingly, when the sub-housing 1b is not slid with respect to the main housing 1a, the distance between the optical axis of the photographing lens 10 and the optical axis of the strobe light 12 also increases. As in the case of the first embodiment shown in FIG. 1, D is obtained.However, when the sub-housing 1b is slid vertically with respect to the main housing 1a, D 3 is longer than D. Become. In the fourth embodiment, as in the above-described second and third embodiments, the sub-housing 1b is used only when shooting a subject in which the occurrence of red-eye effect is worrisome in flash shooting. Can be slid in the direction away from the main housing 1b for shooting. That is, when shooting the subject with the stop aperture, the shooting mode can be selectively switched depending on whether or not the occurrence of the red-eye effect is a concern. Note that, in the fourth embodiment, the operation of sliding the sub-housing lb with respect to the main housing la can be performed directly by hand, and when the sliding is performed and when the sliding is not performed. The sub-housing 1b is configured to be locked to the main housing 1a at both positions.

The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various forms, modifications, and modifications are within the spirit and scope of the present invention. Etc. are possible.

In the above description of the embodiment, the mobile phone has been described as an example of the mobile information terminal. However, it is needless to say that the present invention can be applied to all other mobile information terminals with other PDAs. . Further, the arrangement of the taking lens and the tropo-light may be reversed in the above-described embodiment, and may be changed to an appropriate position as long as the distance between the two can be ensured. Industrial applicability

As described above, according to the present invention, since the distance between the optical axis of the photographing lens of the camera and the optical axis of the tropolite is sufficiently ensured or variable, the stroboscopic imaging of the subject is performed. In this case, only when preventing or suppressing the occurrence of the red-eye effect, a simple structure and operation that allows only a part of the portable information terminal device to hop up or slide, By increasing the distance between the camera and the strobe light for normal shooting, the occurrence of red-eye can be prevented.
