FIG. 5 shows the signal processing section 10 shown in FIG.
3 is a block diagram for explaining in detail the processing operation of FIG.
In this case, the signal processing unit 103, the image compression / expansion unit 104, the memory unit 105, and the output unit 10 shown in FIG.
It shows a configuration in which only 6 is extracted.

In FIG. 5, the signal processing unit 103 converts the digital image data input from the camera signal processing unit 102 for the image compression / expansion unit 104, and converts it into an input signal of an angle detection signal from the sensor unit 31. Based on this, the angle of view of the input data of the color difference and the luminance of the digital image data from the camera signal processing unit 102 is changed.

Here, the sensor section 31 which is the detecting means,
The folded state (angle) between the two main bodies, that is, the display-side main body 1 and the operation button-side main body 2 is detected.

That is, when the display side main body 1 is closed with respect to the operation button side main body 2, the angle is close to 90 ° [a case where it is determined to be a semi-open state, a state where the display side main body is opened 180 °] Except for the display side body 1
When the operation button side main body 2 is opened and the angle is such that the operation button side main body 2 does not fall even when placed on a plane {see FIG. 3 (b)}], the sensor unit 3
The output level of the angle detection signal supplied from 1 to the signal processing unit 103 is LOW.

When the signal processing unit 103 receives the LOW level detection signal, the signal processing unit 103 performs the conversion process for the image compression / expansion unit 104 without modifying the angle of view.

The reason why the correction is not performed in this way is that when the telephone is placed on a desk or the like and a videophone is used, it can be assumed that the distance between the telephone and the face of the person who is the subject is not so close. Because the faces are close to each other, it is considered that it is unlikely that the face is displayed on the entire screen or only a part of the face is displayed.

On the other hand, 180 ° with reference to the time when the display side main body 1 is closed with respect to the operation button side main body 2.
If the angle is close to [the case where it is determined to be in the open state, including the state in which the display is opened by 180 °,
And the angle at which the operation button side body 2 is opened and falls on a plane {see FIG. 3 (a)}], the angle detection signal output from the sensor unit 31 to the signal conversion processing unit 103 is output. Set the level to HIGH.

Then, the signal processing unit 103 uses the HIG
When an H-level detection signal is input, the angle of view is automatically corrected to reduce the image.

The reason for making such a correction is that when a telephone is held and a videophone is used,
It can be assumed that the distance between the phone and the face of the person who is the subject is close,
Because the face is close to the camera, it may occur that the face is displayed in the full screen or only part of the face is displayed.

Therefore, by performing the correction for automatically changing the angle of view as described above, it is possible to prevent the entire face from falling within the screen and appearing up.

When reproducing or recording an image, the digital image data compressed by the image compression / expansion circuit unit 104 is output to the memory unit 105, and the digital image data recorded in the memory unit 105 is The image is compressed and expanded by the image compression / expansion unit 104 and expanded to an appropriate size, and the output unit 1
It is output to 06.

In the case of transmission / reception, the memory unit 105
The compressed digital image data input to
It is output to the communication protocol control unit 107.

According to this structure, the first main body (display side main body 1) and the second main body (operation button side main body) of the folding type information terminal device are detected by the means for detecting the folded state. Since the state in which the terminal is placed and the state held in the user's hand are automatically estimated by the opening degree with 2) and the image is corrected to an arbitrary size according to those states, For example, when the user holds a videophone or the like in his hand, the image can be reduced and corrected to an appropriate size and displayed even if the face and the camera tend to be close to each other.

Next, a second embodiment of the present invention will be described.

FIG. 6 is a diagram showing a schematic external structure of a mobile phone 100a with a videophone function when the second embodiment of the present invention is applied. In this case, the structure shown in FIG. , A view angle operation button 200 is newly added.

Further, FIG. 7 is different from the above-described automatic image correction processing by the signal processing unit 103 shown in the first embodiment because the angle-of-view operation button 200 shown in FIG. 6 is newly provided. FIG. 3 is a diagram showing a functional block configuration for explaining a processing operation of a signal processing unit 103a when performing processing. In this case, the signal processing unit 10 shown in FIG.
3 illustrates a configuration in which only 3 and the sensor unit 31 are extracted.

Further, in the diagrams shown in FIGS. 6 and 7,
Components having the same functions as those of the components shown in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted here.

That is, in the above-described first embodiment, the sensor unit 31 detects that the display-side main body unit 1 is rotating with respect to the operation button-side main body unit 2 by a predetermined angle or more, so that the videophone can be operated. In the second embodiment shown in FIGS. 6 and 7, the angle of view operation button 200 is set by the user (use By pressing the button, the correction process can be operated or the operation can be canceled.

In the second embodiment, the signal processing unit 103a normally receives the detection signal from the sensor unit 31 in accordance with the folded state (predetermined angle) as in the first embodiment. Image correction processing (that is, processing for reducing and correcting an image when opened) is performed. However, when the view angle operation button 200 is pressed by the user, a correction process that is in contrast with the input signal from the sensor unit 31 is performed.

Specifically, when the angle between the display-side main body 1 and the operation button-side main body 2 is in the semi-open state, the signal processing unit 103 normally performs image correction by the angle detection signal from the sensor unit 31. However, if the angle of view operation button 200 is pressed by the user, the signal processing unit 10
3 applies image correction. That is, the same correction processing as in the open state is performed.

On the other hand, when the angle between the display-side main body 1 and the operation button-side main body 2 is in the open state, the signal processing unit 1 is normally operated by the angle detection signal from the sensor unit 31.
03 applies image correction, but when the user presses the view angle operation button 200, the signal processing unit 103 cancels the image correction. That is, the correction process is not performed in the same manner as in the semi-open state.

According to such a configuration, the user can arbitrarily cancel the automatic correction process shown in the first embodiment,
It is possible to operate it.

That is, if the view angle operation button 200 is pressed in the semi-open state, the automatic view angle correction process is operated if the image to be displayed on the display screen is made smaller even in the semi-open state. The image can be reduced and corrected, improving usability. Further, if the view angle operation button 200 is pressed in the open state, if the image displayed intentionally on the display screen is desired to be up, the image can be displayed in the up state by canceling the automatic view angle correction process. It will be easier to use.

In the first and second embodiments described above,
The case where the present invention is applied to a moving image has been described, but the present invention is not limited to this and may be applied to a still image.

Further, in the above embodiment, the display side main body 1 is operated by the angle sensor portion 31 and the operation button side main body 2 is operated.
The usage status is determined by detecting that the sensor 31 is rotated by a predetermined angle or more, but the present invention is not limited to this, and is applied to a foldable mobile phone in which the angle changes in advance in several steps, and the sensor 31 The section may detect the above-mentioned stage to determine the use situation and automatically perform the correction process necessary for photographing a person.

Finally, the folding state (angle) of the display-side main body 1 and the operation button-side main body 2 which is installed in the hinge portion 3 described in the first and second embodiments and is accompanied by the rotation of the hinge portion 3 is set. ) Will be described in detail.

When such a rotation angle detection sensor is used, the movable contact portion 303 rotates together with the shaft 301 due to the rotation of the shaft 301 with the opening of the display-side main body 1 with respect to the operation button main body 2. Then, when the movable contact portion 303 touches the terminal 305 connected to the fixed contact piece 304 that is electrically connected, an electrically closed circuit (not shown) is formed. Further, the terminal 305 to be opened / closed changes depending on the rotation angle of the shaft 301.

That is, the non-conductive state is determined to be the semi-open state, and the conductive state is determined to be the open state.

01 shows a state of rotating about 90 °, and FIG. 9B shows a state of rotating the shaft 301 about 180 °.

That is, in FIG. 9A, in this case, the mobile phone 100 is in a semi-open state, and the fixed contact piece 30.
4 and the movable contact portion 303 of the shaft 301 are in a non-conductive state. At this time, the signal processing unit 10 from the sensor unit 31
The output level of the angle detection signal (described in FIG. 5) supplied to 3 becomes LOW.

Further, in FIG. 9B, in this case, the mobile phone 100 is in the open state, and the fixed contact piece 304
Then, the movable contact portion 303 of the shaft 301 becomes conductive. At this time, the output level of the angle detection signal (described in FIG. 5) supplied from the sensor unit 31 to the signal processing unit 103 becomes HIGH.

In the embodiment described above, the sensor unit 31 is folded using the rotation angle detection sensor which is electrically opened and closed by the electrically contacting fixed contact piece 304 and movable contact section 303 contacting each other. ) Is detected, the folded state (angle) may be detected using a sensor that detects the rotational position of the rotating body using a magnetic conversion element.
