2. Description of the Related Art For example, various types of electronic image display devices for displaying an electronic image captured by an electronic camera or the like in a viewable manner have been proposed, and an image pickup surface of an image pickup device such as a CCD is generally used. It has a rectangular shape with long sides and short sides, and the electronic image taken thereby has a rectangular shape correspondingly, and the image display section is also a rectangular shape with a general aspect ratio. There are many.

In an electronic image display device having such a rectangular image display section, a vertically long installation posture in which the long side is vertical and a horizontally long installation posture in which the long side is horizontal can be selectively performed. The present applicant has proposed in Japanese Patent Application No. 10-126335 a configuration that can be taken. In the invention described in this application, it is further determined whether the installation posture is portrait or landscape. Is automatically determined, and the display direction of the image is appropriately controlled in accordance with the installation posture.

[0004] With this, the electronic image can be displayed as an erect image without depending on the installation posture. Therefore, regardless of whether the electronic image is vertically long or horizontally long, the installation posture of the electronic image display device is changed each time. Need not be changed to
Usability has improved.

The electronic image displayed on the electronic image display device is not limited to an image captured by an electronic camera, but may be an image captured by a scanner or a film scanner, or computer graphics created on a computer. Various types are conceivable, and the ratio of the long side to the short side may be various.

In particular, for example, in photographing with an electronic camera, not only is one image taken as one composition by one release operation, but also one subject is divided into a plurality of parts and each part is divided into one image. In some cases, one electronic image, for example, one panoramic image is obtained by pasting the plurality of original images together, and in such a case, the electronic image is elongated in one direction. .

However, the above-described conventional electronic image display apparatus focuses on displaying an electronic image composed of a single image, and is not applicable to a panoramic image created by combining a plurality of images. Is not specifically considered, and there is room for further improvement in usability.

When such a narrow panoramic image is to be displayed by a conventional electronic image display device, what kind of display is performed will be described with reference to FIGS. FIG. 14 showing a display example in FIG.
This will be described with reference to FIG.

FIG. 3 shows, for example, an electronic camera in a normal photographing posture in which an image pickup surface thereof is horizontally long, and three continuous images are photographed while turning the electronic camera in the horizontal direction and recorded on an image recording medium. After that, the image recording medium is mounted on an electronic image display device to read out these three continuous images, and these original images are pasted together and combined as one electronic image.

That is, in the example shown in FIG. 3, when an elongated object is photographed, a part of the object is photographed as one image P1 forming a horizontally long rectangle, and is contiguous to this image P1. The other parts of the subject are sequentially photographed as horizontally long rectangular images P2 and P3, and after photographing, the plurality of original images P1, P2 and P3 are stuck together on the short sides to form a single panorama. This is an image created.

When such an image is displayed by an electronic image display device having a horizontally long installation posture, that is, when the long side direction of the original image and the long side direction of the image display section are substantially parallel, FIG. As shown in FIGS. 4 (A), (B) and (C), any of the original images P1, P2 and P3 constituting the panoramic image is displayed so as to occupy almost the entire display surface 7a. Then, when it is desired to observe a portion other than the currently displayed one, by performing an operation of changing to the next one screen adjacent to the currently displayed one screen, that is, by performing a so-called page turning operation. 4 (A), (B),
(C) is displayed.

Next, when an image as shown in FIG. 3 is displayed by an electronic image display device having a vertically long installation posture, that is, the long side direction of the original image and the long side direction of the image display section are substantially the same. When they are perpendicular to each other, the positional relationship between the display surface 7a and the electronic image becomes a relationship rotated by 90 degrees.
As shown in FIG. 4, a part of the panoramic image is displayed while leaving a blank area where no image is displayed above and below. Further, when it is desired to observe another portion of the panoramic image, the portion to be displayed is moved by the length of the short side of the display surface 7a to display the adjacent area.

When the long side direction of the original image and the long side direction of the image display section are substantially orthogonal to each other, the margins and the like generated include the direction of the original image, the bonding direction, the direction of the image display section, and the like. Are classified into several cases. Therefore, these will be described in more detail with reference to FIGS. 5 to 8 according to the embodiment of the present invention.

First, the case shown in FIG. 5 is the same as the case shown in FIGS. 3 and 14 described above, and therefore, blanks are generated above and below the image as shown in FIG. 5B.

FIG. 6 shows a case in which, for example, an electronic camera is taken in a vertically long shooting posture and shot while being turned in the vertical direction, and these images are combined so that the short sides are stuck together. When the display unit 7a is in the horizontally oriented installation posture, blanks are generated on the left and right sides of the image as shown in FIG. 6B.

Next, the case shown in FIG. 7 is a case where, for example, an electronic camera is taken in a horizontally long shooting posture while shooting while turning the camera in the vertical direction, and the images are synthesized so that the long sides thereof are stuck together. When the image display unit 7a is in the installation position in which the image display unit 7a is vertically long, the left and right parts of the image are cut off and an undisplayed portion is generated as shown in FIG. 7B.

Further, the case shown in FIG. 8 is, for example, a case where the electronic camera is shot in a vertically long shooting posture while swinging in the horizontal direction, and the images are synthesized so that the long sides thereof are stuck together. When the display unit 7a is in the horizontally oriented installation posture, as shown in FIG. 8B, the upper and lower portions of the image are cut off, and an undisplayed portion is generated.

A horizontal position support surface 23a for supporting the electronic image display device 21 in a horizontally long installation posture and a vertical position support surface 23b for supporting the electronic image display device 21 in a vertically long installation posture are provided. For example, the display unit direction detection switch 11 is provided on the lateral position support surface 23a.

The display section direction detection switch 11 is constituted by, for example, a push switch, and is turned on when the lateral position support surface 23a contacts an installation surface such as a desk, and is turned off when it is separated from the installation surface. Has become.

Thus, the system controller 8
When the display unit direction detection switch 11 is turned on, it is determined that the installation position is horizontally long, and when it is off, it is determined that the installation position is vertically long.

Next, an example of an electronic image to be displayed by the electronic image display device 21 will be described with reference to FIG. FIG. 3 is a diagram showing one panoramic image created by pasting together the short sides of three horizontally long original images.

FIG. 3 shows, as described also in the above-mentioned conventional example, a case in which the electronic camera is set in a normal photographing posture in which the imaging surface is horizontally long, and the electronic camera is turned three times while turning the electronic camera in the horizontal direction. A continuous image is photographed and recorded on the image recording medium 1, and thereafter, the image recording medium 1 is mounted on the electronic image display device 21 to read out these three continuous images, and these original images are pasted together to form one image. This is synthesized as an electronic image.

That is, in the example shown in FIG. 3, for example, an elongated object such as a train is photographed in three images along the longitudinal direction, and then these original images P1, P2,
P3 is bonded by the bonding processing unit 4 to obtain one panoramic image.

FIG. 4 is a diagram showing a state where each original image constituting the panoramic image shown in FIG. 3 is displayed on a display surface 7a of the image display unit 7 one by one.

The electronic image display device 21 can of course display an electronic image composed of a single original image, and displays each of the original images P1, P2 and P3 as an independent image. 4 (A), (B), (C)
It becomes as shown in.

At this time, the display control section 6 controls the display direction of the electronic image to be displayed on the image display section 7 in accordance with the detection result of the display section direction detection switch 11. Regardless of whether the display device 21 is in the vertical installation orientation or the horizontal installation orientation, the vertical and horizontal positions and the enlargement / reduction of the displayed image are appropriately performed so that the displayed image can be observed at the correct vertical and horizontal positions. ing.

In the electronic image display device 21, a single electronic image is displayed on the display surface 7a of the image display unit 7 as much as possible according to the user's preference, regardless of the installation posture. It is also possible to make it. In the case of performing such display, for example, when observing an image photographed at a vertically long photographing position in a horizontally long installation posture, the image is observed in a state rotated by 90 degrees.

The electronic image display device 21 is also capable of displaying a panoramic image or the like created by bonding as shown in FIG.

Since the aspect ratio of the panoramic image is often greatly different from the aspect ratio of the display surface 7a of the image display unit 7, if the entire panoramic image is to be displayed on the image display unit 7 at one time. It must be extremely reduced and may not always be an appropriate display.

In such a case, a part of the continuous panoramic image is cut out and partially displayed, and the whole displayed can be observed by changing the displayed part. Is more preferred.

The classification of the pasting state of the panoramic images and the installation position of the electronic image display device 21 at this time will be described with reference to FIGS.

First, FIG. 5A shows a case where original images P1 to P3 photographed in the horizontal position are pasted together at their short sides to form one horizontally long image, as in the example shown in FIG. FIG. 6A shows an original image P1 to P3 photographed in a vertical position, which is a single vertically long panoramic image obtained by pasting together short sides thereof, and FIG.
FIG. 8A shows an original image P1 to P3 photographed in the horizontal position, which is a single vertically long panoramic image obtained by pasting together the long sides thereof. FIG. The obtained original images P1 to P3 are pasted together on their long sides to form one slightly horizontally long panoramic image.

FIG. 10 shows a specific display example of FIG. 7A.

A case where such a panoramic image is displayed in a state where the long side direction of the original image and the long side direction of the image display section are substantially matched will be described.

In the case of FIG. 5A, the electronic image display device 2
When 1 is in the landscape orientation, the vertical and horizontal directions of the original image and the vertical and horizontal sides of the display surface 7a are in the same direction, and therefore, as in the case of displaying a single electronic image as described above,
First, the portion of P1 is displayed on the display surface 7a. Then, when the user wants to observe another part of the panoramic image, by operating the scroll switch 12, the display range on the panoramic image is sequentially shifted in the direction of P2, and the screen is scrolled.

In the case of FIG. 6A, the electronic image display device 21
Is in a vertically long installation posture, the electronic image display device 21 is in a horizontally long installation posture in the case of FIG. 7A, and the electronic image display device 21 is in a vertically long installation posture in FIG. 8A. 5A, the vertical and horizontal directions of the original image and the vertical and horizontal directions of the display surface 7a are in the same direction. Therefore, as in the case of FIG.
Is operated to scroll the screen.

Here, an example in which the display is performed by scrolling the screen has been described, but it is needless to say that the display image may be switched by turning the page.

In the case where the display is performed in a state where the long side direction of the original image and the long side direction of the image display section are substantially orthogonal to each other, that is, in the case of FIG. 6 is in the vertical installation position,
In the case of FIG. 7A, when the electronic image display device 21 is in the horizontally long installation posture, and in the case of FIG. 7A, the electronic image display device 21 is in the vertically long installation posture, FIG. In the case of (A), when the electronic image display device 21 is in the horizontally long installation posture, as described in the above-described conventional example, FIGS. 5 (B), 6 (B), 7 (B), and FIG. 8
A margin and a non-display portion as shown in FIG.

In order to improve such a situation, in the present embodiment, the long side direction of the original image and the image
When the long sides of the original image are substantially orthogonal to each other, the image processing unit 5 determines whether the bonding by the bonding processing unit 4 is performed on the long sides or the short sides of the original image. In response, the following processing is performed.

For example, in the case shown in FIG.
As described above, upper and lower margins are generated (see FIG. 9A).
Therefore, the size in the short side direction of the original image substantially coincides with the size in the long side direction of the image display unit 7 so as not to generate this blank space and to prevent undisplayed portions from being formed above and below the image. Such enlargement processing is performed in the image processing unit 5, and the result is displayed on the image display unit 7 as shown in FIG. 9B. At this time, the portion where the panoramic image is not displayed can be displayed by scrolling or turning the page in the left-right direction as described above.

In the case shown in FIG. 6,
Since the left and right margins are generated as described above, the size of the original image in the short side direction is set to the above-mentioned image display unit 7 so that the blank is not generated and the undisplayed portions are not generated on the left and right sides of the image. The image processing unit 5 performs an enlargement process that substantially matches the size in the long side direction, and displays the result on the image display unit 7.

Next, in the case shown in FIG. 7 or FIG. 10, since undisplayed portions are generated on the left and right as described above, the undisplayed portions can be completely displayed. In addition, the size in the long side direction of the original image is set to the image display unit 7 so that no blank space occurs on the left and right of the image.
Is reduced in the image processing unit 5 so as to substantially match the size in the short side direction, and the result is displayed on the image display unit 7. At this time, as for the portion where the panorama image is not displayed, as shown in FIG.
It can be displayed by scrolling up and down.

In the case shown in FIG. 8, undisplayed portions are formed above and below as described above.
The undisplayed portion can be completely displayed, and the size in the long side direction of the original image is set to the image display portion 7 so that no blank space is generated at the top and bottom of the image.
Is reduced in the image processing unit 5 so as to substantially match the size in the short side direction, and the result is displayed on the image display unit 7.

In this way, when the bonding by the bonding processing section 4 is performed on the short sides of the original image, the image processing section 5 changes the size of the original image in the short side direction to the image display section 7. Image processing is performed so as to substantially match the long side size of the original image. On the other hand, when the bonding is performed on the long sides of the original image, the long side size of the original image is Image processing is performed so as to substantially match the short side direction size.

Next, FIGS. 12 and 13 show examples in which one image is synthesized by combining an electronic image and display information and displayed.

As described above, the electronic image display device 21 is provided with the built-in storage unit 9 for storing calendar information, and this calendar information can be displayed on the image display unit 7. I have.

Further, the electronic image display device 21 can be configured based on a plurality of pieces of information formed by an arbitrary combination of the calendar information as display information and image information of an electronic image read from the image recording medium 1. One electronic image is synthesized by the image processing means 5, and is synthesized by an image display unit 7.
Can be displayed.

Thus, the electronic image display device 21
It can also be used as a desktop calendar or a desktop calendar with photos.

The case where a plurality of pieces of information are combined and displayed will be described in more detail.

When the electronic image display device 21 is in the vertically long installation posture, the display direction detection switch 11 detects the position, and as shown in FIG. And the image information 32 are automatically arranged side by side in the vertical direction and synthesized.
Is displayed.

Also, when the electronic image display device 21 is in the horizontally long installation posture, the image processing unit 5 similarly operates based on the detection result of the display unit direction detection switch 11 as shown in FIG. The calendar information 31 and the image information 32 are automatically arranged side by side in the horizontal direction and synthesized, and this is displayed on the image display unit 7.

In this way, display information such as calendar information and image information are automatically arranged in an appropriate direction in accordance with the installation posture of the electronic image display device 21, so that an easy-to-view display can be performed.

The information to be displayed is not limited to the calendar information. For example, personal information such as a business card and a photograph of the person's face may be displayed in parallel. It is possible to apply. At this time, of course, a plurality of pieces of image information may be displayed in parallel, or a plurality of pieces of display information may be displayed in parallel.

According to the electronic image display device of such an embodiment, even when the long side direction of the original image and the long side direction of the image display section are substantially orthogonal to each other, a margin or a non-displayed area is generated. Without making use of the display area of the image display unit, it is possible to perform appropriate easy-to-view display.

Further, since the installation posture is detected by the display direction detection switch, it is possible to automatically perform appropriate switching of display.

Further, since the image can be viewed by scrolling the image, it is possible to easily confirm the point where the joint between the pages is difficult to confirm in the page turning.

When a plurality of pieces of information such as an electronic image and display information or between electronic images or display information are displayed side by side, an installation orientation is detected and an appropriate arrangement direction is automatically determined in accordance with the installation attitude. Since the display is performed, the display can be easily viewed without performing a troublesome operation.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications and applications are possible without departing from the gist of the invention.
