Abstract

PROBLEM TO BE SOLVED: To provide a display device in which the display direction is easily switched into either of the vertical or the horizontal directions and to provide an electronic device provided with the display device. SOLUTION: An LCD 13 consists of a liquid crystal display having an approximately square shape (1:1=n:n) in which a display region having the aspect ratio of 1:n (n>1) displays a picture. If a mode changeover switch 31 is charged to a lower side, the direction of the display region is set so that the top and the bottom of the display region of the LCD 13 matches with the top and the bottom of a device being used at present as an electronic still camera in the state that the device is held in the horizontally long condition. Thus, the top and the bottom portions becomes non-display regions. On the other hand, if the switch 31 is charged to an upper side, the display region is rotated to 90 deg. in the state that the device is held in the vertically long condition so that the top and the bottom of the display region of the LCD 13 matches with the top and the bottom of the device being used at present as a PHS terminal. Thus, the left and the right become the non-display regions (against the LCD at the time of using the electronic still camera).

Further, by switching the display direction of the display area, the scale of the display image is not changed, and a part of the display image is not cut off.

B. Second Embodiment Next, a second embodiment according to the present invention will be described. In the second embodiment, when the multifunction device is used as an electronic still camera (or may be a single electronic still camera), a conventional technology that occurs when an attempt is made to capture a vertically long subject in a full frame frame. It is intended to solve the problem.

B-1. Configuration of the Second Embodiment As described above, the gripping form of the composite device of the present invention is changed according to the intended use so that it is most easily used in the intended use. For example, when the composite device is used as an electronic still camera, FIG.

B-2. Next, the operation of the multifunction peripheral according to the second embodiment will be described. In the following description, the operation of each unit during a call or photographing is the same as the operation of a normal PHS terminal or an electronic still camera, and a description thereof will be omitted. Here, FIG. 8 is a flowchart for explaining the display switching operation when the multifunction peripheral according to the second embodiment is used as an electronic still camera.

First, in step S20, it is determined whether or not the camera mode is such that it operates as an electronic still camera.
If the mode is other than the camera mode (PHS terminal), the process proceeds to the corresponding process. On the other hand, if the mode is the camera mode, step S2
The process proceeds to step 2 to determine whether or not the mode switch 31 has been operated. If the mode switch 31 has not been operated, the process proceeds to another process. On the other hand, if the mode changeover switch 31 is operated, the process proceeds to step S24, and it is determined whether the switch is turned down or turned up.

If the user desires to take a horizontally long image and turns on the mode changeover switch 31 downward, the process proceeds to step S26. In step S26,
As shown in FIG. 7A, the exposure area of the CCD 1 is 1: n
The aspect ratio is changed so that (n> 1). Next, in step S28, the capture start position of the image signal of the CCD 1 is changed to the start position SP1 in the exposure area as shown in the figure.

As a result, the image captured by the CCD 1
While the device is held horizontally, the image is displayed on the LCD 13 as a horizontally long image as viewed from the user, and is recorded in the flash memory 8 or the like.

On the other hand, if the user desires to shoot a vertically long image in accordance with the subject and turns on the mode switch 31 upward, the process proceeds to step S30. In step S30, as shown in FIG. 7B, the exposure area of the CCD 1 is changed to have an aspect ratio of n: 1 (n> 1). Next, in step S32, the capture start position of the image signal of the CCD 1 is changed to the start position SP2 in the exposure area as shown in the figure. As a result, the image photographed by the CCD 1 is displayed on the LCD 13 as a vertically long image as viewed from the user while the device is held horizontally, and is recorded in the flash memory 8 or the like.

As described above, in the second embodiment, the aspect ratio of the exposed portion of the CCD 1 is switched in accordance with the operation of the mode changeover switch 31, and the start position of image signal capture is switched in accordance with the exposed portion. Thereby, as shown in the figure, both the horizontally long image and the vertically long image can be photographed without rotating the housing of the multifunction peripheral. Therefore, since it is not necessary to rotate the housing, shooting can be performed without lowering the angle of view, and the number of effective pixels can be improved, camera shake can be reduced, and the color tone in the field of view can be improved. Can be.

In the second embodiment described above, the CCD 1

That is, in the third embodiment, the moving direction (top and bottom) of the housing is detected, the top and bottom (up and down) of the image data to be captured is recognized, and the character information is added so as to match the direction. That is. The details will be described below.

C-1. Third Embodiment Configuration FIG. 9 is a block diagram showing a configuration of a multifunction peripheral according to a third embodiment of the present invention. The parts corresponding to those in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. The components newly added in the third embodiment are a timer 25 and a movement direction sensor 26. The timer 25 counts a predetermined system clock and counts the current time and date. The current time and date are used as character information added to the image data. For this reason, a character for displaying the current time and date is stored in the ROM 22.

The moving direction sensor 26 detects the rotation angle of the multi-function device.
As shown in FIG. 10A, the camera is turned to the subject in the horizontal direction, which is a normal use mode, or is rotated by 90 ° to shoot a vertically long subject as shown in FIG. 10B. Is detected, and angle information corresponding to the rotation angle is supplied to the CPU 21. Here, FIG. 10 is a front view showing an example of the configuration of the movement direction sensor 26. In the figure, a column 27 has a rotatable fulcrum at one end and a weight 28 at the other end. One end of the support column 27 is connected to a rotation axis of a rotation angle sensor 29. The column 27 rotates so that the weight 28 always faces the direction of gravity according to the rotation angle (gripping angle) of the composite device. Therefore, the rotation axis of the rotation angle sensor 29 also rotates in accordance with the rotation of the column 27. The rotation angle sensor 29 sends out an output voltage according to the rotation angle of the rotation shaft.

In accordance with the angle information from the moving direction sensor 26, the CPU 21 changes the position at which the CCD 1 starts capturing image signals in the exposure area, and also changes the scanning direction, the number of horizontal dots, and the number of vertical dots. The details of this will be described later. Further, the CPU 21 creates character information based on the current time and date from the timer 25 and determines a position at which the character information is displayed with respect to the image data based on the angle information from the moving direction sensor 26. It is determined, and image processing is performed to add the created character information to the position.

C-2. Operation of Third Embodiment The user desires to take a horizontally long image, and FIG.
As shown in (a), when the composite device is gripped in the horizontal direction, the aspect ratio of the exposure area of the CCD 1 is set to 1: n (1
> N), and the start position of capturing the image signal is set as the start position SP3 in the exposure area. In this case, the main scanning direction is the illustrated x-axis direction, and the sub-scanning direction is the y-axis direction. Next, at the timing when the image data captured from the CCD 1 is displayed on the LCD 13, character information is created based on the current time and date from the timer 25, and character information is created based on the angle information from the moving direction sensor 26. The position in the image data to which the information is to be added is determined, and the created character information is added to the position shown. As a result, the character information is displayed on the LCD 13 at a position and a direction that match the top and bottom (vertical direction) of the image data.

On the other hand, the user desires to shoot a vertically long image in accordance with the subject, and as shown in FIG.

It can be determined that the multi-function device (electronic still camera) is vertically oriented so that the C side is at the bottom, and shooting is being performed.

Therefore, if the support B is electrically connected to the terminal A, it means that the multifunction device was photographed in the state shown in FIG. 14A, so that it matches the top and bottom (up and down) of the image data. As described above, the character information may be added so that the right direction is upward at the lower left of the screen when viewed on the LCD 13 at the normal time when the composite device is photographed sideways. In addition, support B
If the terminal is not electrically connected to either of the terminals A and C, it means that the composite device was photographed in a state as shown in FIG. 14B, that is, in a normal state. Character information may be added so that

Similarly, if the column B is electrically connected to the terminal C, it means that the multifunction device was photographed in the state shown in FIG. Character information may be added so as to match, so that the left direction is on the upper right of the screen when viewed on the LCD 13 in a normal state. Thus, when the user views the image data in the correct direction, the character information is displayed in the correct direction at the lower right of the image data.

As shown in FIGS. 15A and 15B, a predetermined container 3 is used as the moving direction sensor 26 described above.
5 encloses a liquid 36 and a column 39 having a rotatable fulcrum 37 at one end and a float 38 made of a member having a lower specific gravity than the liquid 36 at the other end.
8, a rotation angle sensor 41 connected to a rotation shaft 40 is provided,
Utilizing the fact that the column 39 is rotated so that the float 38 always comes upward due to the buoyancy, the direction of the photographing (moving direction) is detected from the output of the rotation angle sensor 41.

Then, based on the moving direction, character information such as the current time (shooting time) and the date is added to the image data at a predetermined position and direction that matches the vertical direction of the image data. . Therefore, similarly to the above-described third embodiment, regardless of whether the composite device (electronic still camera) is photographed horizontally or vertically, character information is displayed in an appropriate position and direction together with image data. can do. As a result, the user can easily visually recognize the character information together with the image data.
