First Embodiment FIG. 1 is an explanatory diagram showing an outline of an embodiment. The communication device 1 is connected to the television receiver 2 via a cable 3. The communication device 1 is a mobile phone, a smartphone, a PDA (Personal Digital Assistance), a game machine, a notebook personal computer, or the like. The cable 3 is a communication cable. The communication device 1 transmits the created image information to the television receiver 2 via the cable 3. The television receiver cuts out and displays an image based on the image information based on the pixel information.

  FIG. 2 is a block diagram showing the configuration of the communication device 1. The communication device 1 includes an input unit 11, a display unit 12, a CPU (Central Processing Unit) 13, a RAM (Random Access Memory) 14, a storage unit 15, an attitude detection unit 16, and a communication unit 17. The CPU 13 includes a determination unit 131, a calculation unit 132, and a communication device control unit 133. The CPU 13 is connected to each part of hardware via a bus.

  The configuration of the communication device 1 will be described. The input unit 11 is a button or a touch panel, and outputs an instruction signal for instructing the CPU 13 to operate. The display unit 12 is a display such as a liquid crystal display, a plasma display, or an organic EL (electroluminescence), and has a rectangular shape and displays an image.

  The attitude detection unit 16 is, for example, a triaxial acceleration sensor, detects the attitude of the communication device 1, and outputs an attitude signal indicating its own attitude to the CPU 13. That is, when the orientation of the communication device 1 is in the portrait orientation, the orientation detection unit 16 outputs an orientation signal indicating the portrait orientation to the CPU 13. On the other hand, when the orientation of the communication device 1 is in the landscape orientation, the orientation detection unit 16 outputs an orientation signal indicating the orientation to the CPU 13. Hereinafter, the case where the long side of the display unit 12 is oriented in the vertical direction is referred to as the vertical direction, and the case where the long side is directed in the horizontal direction is referred to as the horizontal direction. Note that the posture signal may be a signal indicating which of the four surrounding edges on the display screen is on.

  The CPU 13 controls each part of the hardware by reading and executing the control program stored in the storage unit 15. Further, the CPU 13 writes and reads information to and from the storage unit 15.

  The determination unit 131 of the CPU 13 receives the posture signal output from the posture detection unit 16 and determines whether the signal is a signal indicating the portrait orientation or the signal indicating the landscape orientation.

  When the determination unit 131 determines that the posture signal is a signal indicating the vertical orientation, the calculation unit 132 creates image information that is a vertically long image that matches the size of the display unit 12, and Information is output to the display unit 12. The image based on the image information may be a still image or a moving image, and may be an application display screen, a menu screen, or the like. On the other hand, when the determination unit 131 determines that the posture signal is a signal indicating a horizontal orientation, the calculation unit 132 creates image information that forms a horizontally long image that matches the size of the display unit 12, and The image information is output to the display unit 12. Note that the calculation unit 132 may perform calculation so that an image is displayed in a specific direction without depending on a fixed posture signal.

  Further, the calculation unit 132 creates pixel information. The pixel information includes information on the number of pixels in the vertical direction and the horizontal direction, and a cutout position indicating the position of a pixel serving as a reference for cutting out an image. For example, when displaying a vertically long image with a fixed aspect ratio, such as a photo or a moving image, with the communication device 1 in a landscape orientation, no image is displayed on both sides of the display unit 12. In such a case, it is desirable to appropriately cut out only a certain area of the image. Therefore, the CPU 23 to be described later performs a process of cutting out only a part of the region with display contents based on the pixel information created by the calculation.

  FIG. 3 is an explanatory diagram of pixel information. The number of pixels in the one side direction of the display unit 12 and the other side direction perpendicular to the one side direction is set to n pixels and m pixels, respectively (n> m). When the displayed image is a vertically long image with an aspect ratio of n: m, the image is displayed on the entire display unit 12 when the communication device 1 is in the portrait orientation.

  On the other hand, a case where the communication device 1 is in the horizontal direction will be described. At this time, the computing unit 132 performs computation so that the vertically long image of n: m is similarly reduced, and the similar reduced image is arranged and displayed at the center of the display unit 12.

In FIG. 3, the coordinates of x rows and y columns of the display unit 12 are (x, y), and the upper left pixel is (1, 1). A vertically long image of n: m is similarly reduced to an image having m pixels in the vertical direction and n ² / m pixels in the horizontal direction. When such an image is arranged at the center of the display unit 12, an image having m pixels in the vertical direction and n ² / m pixels in the horizontal direction is set with (n / 2−n ² / 2m + 1, 1) being the upper left vertex. . The position indicated by (n / 2−n ² / 2m + 1, 1) is the cutout position. Pixel information is information obtained by adding information such as vertical m pixels and horizontal n ² / m pixels, which indicates the size of an image to be extracted, to the information on the clipping position. In this way, the calculation unit 132 creates pixel information by calculation.

  When the communication device 1 is connected to an external device such as the television receiver 2, the communication device control unit 133 receives the same image information as the image information indicating the image displayed on the display unit 12 via the communication unit 17.

When receiving the pixel information, the determination unit 232 determines the number of pixels in the vertical direction and the horizontal direction in the pixel information.

The image processing unit 233 cuts out an image based on the image information based on the pixel information. That is, an image is created by cutting out an image based on image information in a range of m pixels in the vertical direction and n ² / m pixels in the horizontal direction from the cut position (n / 2−n ² / 2m + 1, 1). Further, the image processing unit 233 performs a process of enlarging the clipped image so as to correspond to the number of pixels of the display unit 22.

The display determination unit 234 displays a screen on the display unit 12 according to the setting.

  Subsequently, an operation process performed by the CPU 13 will be described. FIG. 7 is a flowchart showing the operation process of the CPU 13. The CPU 13 inputs an attitude signal from the attitude detection unit 16 (S101), and creates image information and pixel information corresponding to the attitude signal (S102). Further, the pixel information is stored in the storage unit 15 (S103). The CPU 13 displays an image based on the created image information on the display unit 12 (S104).

  On the other hand, the CPU 13 determines whether or not a connection signal has been received (S105). If not received (NO in S105), the CPU 13 receives the attitude signal again (returns to S101). When the connection signal is received (YES in S105), the CPU 13 reads pixel information from the storage unit 15 (S106).

  On the other hand, an operation process performed by the CPU 23 will be described. FIG. 8 is a flowchart showing the operation process of the CPU 23. The CPU 23 determines whether or not the communication unit 17 and the communication unit 27 are connected (S121). If it is determined that it is not connected (NO in S121), the CPU 13 continues to wait (return to S121). When it is determined that they are connected (YES in S121), the CPU 23 receives the pixel information and the image information transmitted from the CPU 13 (S122). Further, the CPU 23 cuts out an image based on the image information based on the pixel information (S123). The CPU 23 determines whether or not the number of pixels in the vertical direction of the pixel information is larger than the number of pixels in the horizontal direction (S124). If the result of the determination is that the number of pixels in the vertical direction is large (YES in S124), the CPU 23 sets the display unit to display two screens of the first screen and the second screen side by side. (S125).

  On the other hand, when the number of pixels in the vertical direction is not large as a result of the determination (NO in S124), the CPU 23 sets to display the second screen (S126). The CPU 23 performs a process of enlarging the image displayed by the image information in accordance with the display unit 22 (S127), displays the set screen on the display unit 12 (S128), and ends the process.

  According to the present embodiment, the number of pixels in one side direction and the number of pixels in the direction perpendicular to the pixel information are determined, and based on the determination result, a direction with a large number of pixels is defined as a vertical direction or a horizontal direction. The clipped image is displayed on the display unit 12. Thereby, the display screen of the display part 12 can be utilized effectively.

Second Embodiment A second embodiment will be described. In the present embodiment, when the two-screen display is performed, the size of the first screen is set according to the size of the second screen.

  A process for setting the size of the display screen according to the first screen will be described. The image processing unit 233 performs processing similar to that of the first embodiment, and performs processing for cutting out image information and enlarging similarities based on pixel information. Here, the image processing unit 233 enlarges the number of pixels in the vertical direction of the clipped image so as to match the number of pixels in the vertical direction of the display unit 22.

  On the other hand, the display determination unit 234 sets the number of pixels in the horizontal direction of the first screen to the number of pixels obtained by subtracting the number of pixels in the horizontal direction of the second screen from the number of pixels in the horizontal direction of the display unit 22. The display determination unit 234 sets the number of pixels in the vertical direction of the first screen so that the number of pixels in the vertical direction and the horizontal direction and the ratio of the display unit 22 are equal to the ratio of the first screen.

  The process in which the display determination part 234 sets a display screen is demonstrated concretely. FIG. 9 is an explanatory diagram regarding the size of two screens. It is assumed that the number of pixels of the display unit 22 is vertical e pixels and horizontal f pixels, and an image cut out by the CPU 23 based on the pixel information is vertical c pixels and horizontal d pixels. The display determination unit 234 sets the second screen with the vertical direction e pixels and the horizontal direction de / c pixels to be displayed on the right side of the display unit 22. Here, the image processing unit 233 performs processing for converting the cut-out image into an image of vertical e pixels and horizontal de / c pixels.

On the other hand, the display determination unit 234 sets the number of pixels in the horizontal direction of the first screen to f-de / c pixels obtained by subtracting de / c pixels from f pixels. The ratio of the number of pixels in the vertical direction and the horizontal direction of the first screen is e: f as in the display unit 22. Therefore, the display determination unit 234 sets the number of pixels in the vertical direction of the first screen to e-de ² / cf pixels by multiplying the number of pixels in the horizontal direction by e / f.

  For example, it is assumed that the cut image is 480 pixels in the vertical direction and 320 pixels in the horizontal direction, and the display unit 22 is 1080 pixels in the vertical direction and 1920 pixels in the horizontal direction. Then, the image processing unit 233 performs a process of multiplying the vertical direction of the clipped image by 1080/480 = 9/4. The horizontal direction is 320 × 9/4 = 720 pixels. Accordingly, the display determination unit 234 sets the second screen having a vertical direction of 1080 pixels and a horizontal direction of 720 pixels to be displayed on the right side of the display unit 22. On the other hand, the display determination unit 234 sets the first screen to be displayed on the left side of the display unit 12 with the horizontal direction set to 1920-720 = 1200 pixels and the vertical direction set to 1200 × 9/16 = 675 pixels. .

  In order to make it easier to see the two screens, an area where no image is displayed having a certain number of pixels in the horizontal direction may be provided between the first screen and the second screen.

  FIG. 10 is a flowchart showing the operation process of the CPU 23. The CPU 23 determines whether or not the communication unit 17 and the communication unit 27 are connected (S221). If it is determined that it is not connected (NO in S221), the CPU 13 continues to stand by (return to S221). If it is determined that they are connected (YES in S221), the CPU 23 receives the pixel information and the image information transmitted from the CPU 13 (S222). Further, the CPU 23 cuts out an image based on the image information based on the pixel information (S223). The CPU 23 determines whether or not the number of pixels in the vertical direction of the pixel information is larger than the number of pixels in the horizontal direction (S224). If the result of determination is that the number of pixels in the vertical direction is large (YES in S224), the CPU 23 performs an operation for setting the sizes of the first screen and the second screen (S225). The CPU 23 sets the display unit to display two screens of the first screen and the second screen of the set size in parallel (S226), and proceeds to the processing after S228 described later.

  On the other hand, if the number of pixels in the vertical direction is not large as a result of the determination (NO in S224), setting is made to display only one screen of the second screen (S227). The CPU 23 performs a process of enlarging the image displayed by the image information in accordance with the display unit 22 (S228), displays the image (S229), and ends the process.

  According to the present embodiment, when the display unit 22 displays two screens, the size of the other image is set according to the size of one image, so that the display unit 22 can be used effectively. .

Third Embodiment A third embodiment will be described. In the present embodiment, the screen display of the display unit 22 can be arbitrarily switched between a single screen display and a two screen display.

  When the communication unit 17 and the communication unit 27 are connected via the cable 3, first, the communication device 1 transmits a designation signal that designates the number of screens. For example, when the display unit 22 displays one screen of the first screen, the communication device 1 transmits a designation signal that designates the number of screens as two screens. In this case, the communication device 1 displays one screen of the first screen when the orientation is landscape based on the orientation detected by the orientation detection unit 16 of the communication device 1 and when the orientation is portrait. May transmit a designation signal for displaying two screens of the first screen and the second screen.

  The designation signal may be transmitted from the remote control device 5 and received by the CPU 23 via the remote control receiving unit 26. In addition, the designation signal may be a signal instructing to switch between the one-screen display and the two-screen display.

  The designation signal is transmitted from the CPU 13 and received by the CPU 23 via the communication units 17 and 27 and the cable 3. At this time, the CPU 23 performs a process of switching the display unit 12 to display two screens of the first screen and the second screen according to the designation signal.

  On the other hand, when the display unit 22 displays two screens of the first screen and the second screen, the communication device 1 transmits a designation signal that designates the number of screens as one screen. The CPU 23 accepts the transmitted designation signal. At this time, the CPU 23 performs a process of switching the display unit 12 to display one screen of the second screen according to the designation signal 12.

  FIG. 11 is a flowchart showing the operation process of the CPU 23. The CPU 23 determines whether a designation signal has been received (S321). When the designation signal is not received (NO in S321), the standby is continued (returned to S321). When the designation signal is accepted (YES in S321), the CPU 23 determines whether or not the number of screens displayed on the display unit 22 at the time of acceptance matches the number of screens designated by the designation signal. (S322). If they match (YES in S322), the CPU 23 ends the process while maintaining the number of screens. If they do not match (NO in S322), the CPU 23 switches the number of screens displayed on the display unit 22 (S323) and ends the process.

  According to the present embodiment, it is possible to specify whether the screen displayed on the display unit 22 is one screen or two screens, so that a screen desired by the viewer can be displayed.

Fourth Embodiment A fourth embodiment will be described. In the present embodiment, when the screen display is a two-screen display, the left and right screens can be switched.

  When two screens are displayed side by side on the display unit 22 so that the first screen is on the left side and the second screen is on the right side, the remote control device 5 instructs the replacement of the left and right screens. Send. The replacement signal is received by the CPU 23 via the remote control receiving unit 26. In accordance with the replacement signal 12, the CPU 23 performs processing for setting the first screen to the right side and the second screen to the left side.

  The designation signal may be transmitted from the communication device 1 and received by the CPU 23.

  FIG. 12 is a flowchart showing the operation process of the CPU 23. The CPU 23 determines whether a replacement signal has been received (S421).
