Hereinafter, an embodiment will be described.
As illustrated in FIG. 1, the display system includes an imaging device 10, a processing device 20, and a display device 30.

The imaging device 10 outputs image data RG obtained by capturing the entire surrounding image.
The processing device 20 includes a sensor interface (denoted as “sensor I / F”) 21, an image data processing unit 22, a display interface (denoted as “display I / F”) 23, a central processing unit (CPU) 24, and a memory 25. , And a recording medium interface (denoted as “recording medium I / F”) 26. The image data processing unit 22, CPU 24, memory 25, and recording medium interface 26 are connected to each other via a bus 27.

The sensor interface 21 receives the image data RG output from the imaging device 10 and outputs it to the image data processing unit 22.
The image data processing unit 22 performs processing on the image data output from the sensor interface 21 and stores the processed image data in the memory 25. The memory 25 is an example of a recording unit. Further, the image data processing unit 22 performs processing on the image data read from the memory 25 and stores the processed image data in the memory 25.

  The recording medium interface 26 inputs and outputs data to and from the recording medium 40 that can be attached to and detached from the processing device 20. The recording medium 40 is a memory card, for example, and is installed in a slot of the processing device 20.

  The CPU 24 controls the image data processing unit 22 and the like according to an operation of an operation unit (not shown). For example, the CPU 24 sets a setting value corresponding to the operation mode set according to the operation of the operation unit in the image data processing unit 22 or the like. Further, the CPU 24 transfers image data from the memory 25 to the recording medium 40 or from the recording medium 40 to the memory 25 in accordance with the operation of the imaging unit.

  The image data processing unit 22 reads the data stored in the memory 25 and converts the image data according to the display device 30. Then, the image data processing unit 22 outputs the converted image data. The display interface 23 outputs the image data output from the image data processing unit 22 to the display device 30.

As shown in FIG. 2A, the display device 30 has a cylindrical display panel 31. The display panel 31 is a liquid crystal display panel (LCD), for example.
The cylindrical display panel 31 includes a display portion 32 and terminal portions 33 and 34 at both ends of the display portion 32 (both ends in the axial direction of the cylinder (vertical direction in FIG. 2A)). The cylindrical display panel 31 is formed by curving the plate-like display panel 31 as shown in FIG. Since the cylindrical display panel shown in FIG. 2A and the plate-like display panel shown in FIG. 2B have the same configuration, the same reference numerals are used for description.

  The shape of the display panel 31 is, for example, a parallelogram. In the display panel 31, terminal portions 33 and 34 are formed along a pair of sides 31a and 31b, and terminal portions are formed on the other pair of sides 31c and 31d. Not. As shown in FIG. 2A, the cylindrical display panel 31 is formed by bending a plate-like display panel 31 so that a pair of sides 31c and 31d where no terminal portions are formed abut each other. .

  As shown in FIG. 2C, the display panel 31 has a plurality of subpixels 35. The sub pixel 35 is an example of a display pixel. The sub-pixels 35 are arranged along two arrangement axes AX and AY that extend along the surface of the display panel 31 on a plane and intersect each other. For example, the array axis AX and the array axis AY are set to be orthogonal to each other. The array axis AX is set so as to form a predetermined angle with respect to the side 31a where the terminal portion 33 of the display panel 31 is formed. An angle (acute angle) between the array axis AX and the side 31a is, for example, 45 degrees. Similarly, the angle (acute angle) between the array axis AY and the side 31a is 45 degrees.

  In the display panel 31, the side 31 d where no terminal portion is formed is formed in parallel with the array axis AY. Therefore, the angle between the side 31a where the terminal portion 33 is formed and the side 31d where the terminal portion is not formed is 45 degrees. Similarly, as shown in FIG. 2B, the angle between the side 31b where the terminal portion 34 is formed and the 31c where the terminal portion is not formed is 45 degrees.

  As shown in FIG. 2C, electrodes DX and DY are formed on the display panel 31 along the arrangement direction of the sub-pixels 35. The electrodes DX and DY are examples of a first electrode and a second electrode. The electrode DX is formed in parallel with the array axis AX, and the electrode DY is formed in parallel with the array axis AY. The electrode DX is called a data line or a signal line, and the electrode DY is called an address line, a gate line or a scanning line. Each electrode DX, DY is connected to a corresponding terminal TX, TY formed on the terminal portion 33. Terminals TX and TY are examples of a first terminal and a second terminal. Note that FIG. 2C schematically shows the sub-pixel 35 and the electrodes DX and DY, and the positional relationship and size of the sub-pixel 35 and the electrodes DX and DY may be different from actual ones. Although not shown in FIGS. 2A to 2C, similarly, terminals TX and TY are formed in the terminal portion 34, and the terminals TX and TY are connected to the electrodes DX and DY, respectively.

  In the display panel 31 shown in FIG. 2B, a terminal TX connected to the electrode DX and a terminal TY connected to the electrode DY are formed on a pair of sides 31a and 31b of the two pairs of sides. Therefore, as shown in FIG. 3A, the cylindrical display panel 31 is formed by abutting the pair of sides 31c and 31d, on which the terminal portion is not formed, of the two pairs of sides. In this case, as shown in FIG. 3B, the arrangement interval L1 between the two sub-pixels 35 sandwiching the abutted sides 31c and 31d is equal to the arrangement interval L2 between the two sub-pixels 35 formed in the other part. Almost equal. Therefore, a visual break is not generated in the pixels displayed by the display panel 31.

Next, a comparative example of the display device will be described.
As shown in FIG. 4A, the rectangular display panel 101 is bent to form a cylindrical display panel. As shown in FIG. 4B, the display panel 101 has terminal portions 102 to 105 formed in the periphery. As shown in FIG. 4C, the display panel 101 has sub-pixels 106 arranged along the sides. The terminal 111 formed in the terminal portion 102 is connected to an electrode 115 extending in a direction orthogonal to the side on which the terminal 111 is formed. Similarly, the terminals 113 and 114 formed in the terminal portions 104 and 105 are connected to electrodes 117 and 118 extending along a direction orthogonal to the sides. Therefore, the display panel 101 is shaped into a cylindrical shape (see FIG. 4A) so that the terminal portions 104 and 105 overlap. In this case, the arrangement intervals of the sub-pixels 106 are wider than the arrangement intervals (pitch) of other portions by the terminal portions 104 and 105. For this reason, a visual break occurs in the displayed image.

Next, generation of image data supplied to the display panel 31 of the present embodiment will be described.
As illustrated in FIG. 5, the imaging device 10 includes a drive unit 11 and an imaging unit 12.
The drive unit 11 includes a motor such as a stepping motor, for example, and rotates the imaging unit 12 around a vertical axis at a predetermined speed.

  The imaging unit 12 includes, for example, an imaging optical system and an imaging element (image sensor) 13. The imaging optical system includes one or more lenses that collect light from a subject, a diaphragm that adjusts the amount of light that has passed through the lens, and the like. The image sensor 13 is a CCD, a CMOS image sensor, or the like, and includes a color filter. The image sensor 13 generates image data corresponding to the incident light. The image data includes information such as luminance corresponding to the amount of incident light and color information corresponding to the color filter.

  The image sensor 13 has, for example, a plurality of pixels (photographing pixels) arranged two-dimensionally. The imaging element 13 outputs pixel data generated by a plurality of shooting pixels arranged in a first direction (for example, the column direction). The imaging device 13 outputs the image data obtained by one shooting by repeating the output of the plurality of pixel data along the second direction (for example, the row direction). A plurality of pixel data generated by a plurality of photographing pixels arranged along the first direction (column direction) is referred to as line data. Image data obtained by one imaging includes a plurality of line data.

  The image pickup device 13 is fixed to the image pickup unit 12 with an angle inclination according to the arrangement direction (tilt of the arrangement axis) of the sub-pixels 35 included in the display panel 31 of the display device 30. For example, the imaging device 13 is fixed so that the angle between the direction in which a plurality of imaging pixels that generate one line data is arranged and the vertical direction is equal to the angle in the arrangement direction AY of the display panel 31. .

  The imaging element 13 scans a plurality of imaging pixels at every predetermined angle, and outputs image data corresponding to the light incident on each imaging element. The angle at which the photographic pixel is scanned is set according to the number of pixel data (number of pixels) included in block image data BG, which will be described later, and the number of sub-pixels 35 (number of display pixels) included in the display panel 31. For example, the imaging device 13 scans a plurality of imaging pixels every “11.25 degrees” and outputs image data. Therefore, the image sensor 13 captures an image of the entire circumference (360 degrees) by 32 scans.

  The sensor interface 21 illustrated in FIG. 1 outputs block image data BG including a plurality of line data among the image data output from the imaging unit 12 to the image data processing unit 22. For example, the sensor interface 21 outputs block image data BG including a plurality of (for example, “12”) line data including imaging pixels on the optical center (optical axis) among image data obtained by one scan. . The number of pixel data included in one line data is equal to or greater than the number of sub-pixels 35 arranged along the arrangement axis AY of the display panel 31.

  As shown in FIG. 6, a plurality of (32 pieces of block image data BG in FIG. 6) block image data BG are obtained by rotating the imaging unit 12 shown in FIG. 5 once. The image data processing unit 22 illustrated in FIG. 1 extracts pixel data corresponding to the display panel 31 from the plurality of block image data BG and stores the pixel data in the memory 25. In FIG. 6, a region corresponding to the display unit 32 of the display panel 31 is indicated by a dashed frame GF. The vertical width of the frame GF (the interval between two broken lines) corresponds to the vertical width of the display unit 32 in which the sub-pixels 35 are formed in the display panel 31 shown in FIG. The image data processing unit 22 stores the pixel data extracted according to the display unit 32 among the plurality of pixel data included in each line data in the memory 25 shown in FIG.

  Then, the image data processing unit 22 aligns the pixel data when storing the extracted pixel data in the memory 25. The alignment of the image data is to convert the arrangement of pixel data included in the block image data BG into a rectangular arrangement.

The pixel data alignment (array conversion) will be described.
FIG. 7 shows the extracted pixel data PG for one frame along the pixel arrangement direction. In FIG. 7, a plurality of pixel data extracted from one block image data BG are collectively shown as one pixel data PG. The X axis corresponds to the pixel arrangement direction in each line data, and the Y axis corresponds to the pixel arrangement direction between the line data. The position on the X axis (X number) and the position on the Y axis (Y number) indicate one pixel data PG.

  As shown in FIG. 2C, the sub-pixel 35 of the display panel 31 is formed according to the intersection of the electrode DX and the electrode DY that intersect each other. Accordingly, each sub-pixel 35 is selected by the electrode DX and the electrode DY. The position (number) of the electrode DX corresponds to the position (X number) of the pixel data on the X axis shown in FIG. 7, and the position (number) of the electrode DY corresponds to the position (Y) of the pixel data on the Y axis shown in FIG. Number).

  As shown in FIG. 8, for example, the block image data BG obtained by one scan includes 12 columns × 42 pixel data PG. In FIG. 8, a broken line extending in the horizontal direction indicates the display unit 32 in the display panel 31 shown in FIG. Therefore, as shown in FIG. 9, one block image data BG includes effective pixel data EG indicating a position by a circle and invalid pixel data VG indicating a position by a square. The valid pixel data EG is included in the display unit 32 illustrated in FIG. 8, and the invalid pixel data VG is not included in the display unit 32. When describing the effective pixel data EG, it may be simply referred to as pixel data EG.

  The imaging device 10 illustrated in FIG. 1 outputs pixel data according to, for example, a synchronization signal (vertical synchronization signal and horizontal synchronization signal) and a clock signal. The sensor interface 21 receives pixel data based on the synchronization signal and the clock signal. Therefore, when the pixel data (effective pixel data EG) included in the plurality of block image data BG is arranged in accordance with the output order of the imaging device 10, as shown in FIG. 10, a useless area in which no data is stored in the memory 25 Occurs. For this reason, the image data processing unit 22 aligns the pixel data.

  As shown in FIG. 11, for a plurality of effective pixel data EG included in one block image data BG, the position (coordinate value) of the pixel data EG arranged in the horizontal direction is Ax, and the pixel data arranged in the vertical direction Let Ay be the position (coordinate value) of. In FIG. 11, the coordinate value (Ax, Ay) of the pixel data at the left end of the uppermost stage is (1, 1). Accordingly, the coordinate value (Ax, Ay) of the pixel data at the uppermost right end is (30, 1), and the coordinate value (Ax, Ay) of the pixel data at the lowermost right end is (41, 12).

The coordinate values of the aligned pixel data are (Bx, By). The image data processing unit 22 has the following formula:
Bx = Ax−fa (θ, Ay)
By = (Sn−1) × Lb + Ay
Then, the coordinate values (Bx, By) after alignment are calculated.

  In the above equation, θ is the inclination of the image sensor 13 and, as shown in FIG. 6, the inclination of the block image data BG with respect to the vertical direction in the display unit 32. This inclination is equal to the angle between the vertical direction and the scanning direction of the image sensor 13 in the imaging device 10 shown in FIG. The function fa (θ, Ay) calculates the coordinate value of the first effective pixel data EG (the coordinate value of the leftmost effective pixel data EG in FIG. 11) in each column. This function, for example, multiplies tan θ (tangent function) by a value obtained by subtracting a predetermined value (eg, “1”) from the coordinate value Ay, and obtains a value obtained by rounding up the result of the multiplication to an integer. . Sn is the number of scans in the imaging device 10 that captures the entire circumference image and is equal to the number of the block image data BG output from the imaging device 10. Lb is the number of pixel data in the vertical direction of the block image data BG, and is equal to the number of lines of line data in the block image data BG.

When the inclination of the imaging unit 12 shown in FIG. 5 is 45 degrees, since tan (45 °) = 1, the function fa (θ, Ay) is a predetermined value (= 1) from the coordinate value Ay before alignment. Can be an arithmetic expression (Ay-1). In other words, the above formula is
Bx = Ax− (Ay−1)
By = (Sn−1) × Lb + Ay
It can be.

For example, in FIG. 11, the coordinate values (Ax, Ay) of the pixel data at the left end of the lowermost stage are (12, 12). Note that pixel data included in the block image data BG obtained by the first scan is used. In this case, the coordinate values (Bx, By) after alignment are
Bx = 12- (12-1) = 1
By = (1-1) × 12 + 12 = 12
And (1, 12).

Further, in the block image data BG obtained by the third scan, the pixel data EG having the coordinate value (35.6) is expressed by the above formula: Bx = 35− (6-1) = 30
By = (3-1) × 12 + 6 = 30
Thus, the coordinate values (Bx, By) after alignment are (30, 30).

  By this conversion, the pixel data EG shown in FIG. 11 are aligned as shown in FIG. The image data processing unit 22 stores the aligned pixel data EG in the memory 25 according to the coordinate values (Bx, By) of each pixel data.

Next, a process for reading the recording data stored in the memory 25 as reproduction data will be described.
The image data processing unit 22 sequentially reads the recording data according to the coordinate values (Bx, By). Then, the image data processing unit 22 converts the coordinate values (Bx, By) of the read image data into coordinate values (Cx, Cy) corresponding to the arrangement of the sub-pixels 35 of the display panel 31 shown in FIG. The image data processing unit 22 is, for example, the following equation:
Cx = Bx + fb (θ, By)
Cy = By
Accordingly, the coordinate values (Cx, Cy) corresponding to the display panel 31 are calculated.

θ is the inclination in the arrangement direction of the sub-pixels 35 and is equal to the inclination of the image sensor 13.
The function fb (θ, By) calculates an offset amount for offsetting the coordinate value of the effective pixel data EG at the head of each column according to the inclination in the arrangement direction of the sub-pixels 35 of the display panel 31. This function, for example, multiplies tan θ (tangent function) by a value obtained by subtracting a predetermined value (eg, “1”) from the coordinate value Ay, and obtains a value obtained by rounding up the result of the multiplication to an integer. .

In the case of the display device 30 shown in FIGS. 2A to 2C, the inclination of the arrangement of the sub-pixels 35 is 45 degrees. Therefore, since tan (45 °) = 1, the function fb (θ, By) can be an arithmetic expression (Ay−1) that subtracts a predetermined value (= 1) from the coordinate value Ay before alignment. . In other words, the above formula is
Cx = Bx + (By-1)
Cy = By
It can be.

For example, in FIG. 12, the coordinate value (Bx, By) of the top pixel data EG in the 12th column is (1, 12). Based on this coordinate value,
Cx = 1 + (12-1) = 12
Cy = 12
Thus, the converted coordinate values (Cx, Cy) are (12, 12). Therefore, each pixel data EG shown in FIG. 12 is offset as shown in FIG.

  The coordinate values (Cx, Cy) after conversion correspond to the numbers (positions) of the electrodes DX and DY of the display panel 31 shown in FIG. The image data processing unit 22 outputs the reproduction pixel data EG read from the memory 25 and the coordinate values (Cx, Cy) after conversion. The display interface 23 outputs the pixel data EG at a timing according to the coordinate values (Cx, Cy). This pixel data is supplied to the sub-pixels 35 connected to the corresponding electrodes DX and DY. As described above, the image data processing unit 22 sequentially reads the pixel data EG for one frame stored in the memory 25. Then, the image data processing unit 22 converts the read coordinate values (Bx, By) of the pixel data into display coordinate values (Cx, Cy). The display interface 23 outputs each pixel data EG to the display device 30 at a timing according to the coordinate values (Cx, Cy).

  For example, as shown in FIG. 14, the cylindrical display panel 31 includes a plurality of electrodes DX and DY that intersect with each other, and subpixels 35 that are formed according to the intersections of the electrodes DX and DY. The electrodes DX and DY are inclined on the display panel 31 in a state where the display panel 31 is expanded on a plane so as to form a predetermined angle with respect to a straight line parallel to the axis of the cylindrical display panel 31. ing. Therefore, the arrangement direction of the plurality of sub-pixels 35 formed according to the electrodes DX and DY is inclined with respect to the straight line.

  Image data PG for displaying an image on the display panel 31 is obtained by the imaging element 13 in which the arrangement of the photographic pixels is inclined according to the inclination in the arrangement direction of the sub-pixels 35 of the display panel 31, and is stored in the memory 25. To be recorded. As shown in FIG. 15, the image data PG recorded in the memory 25 is inclined with respect to the array axes X and Y of the photographing pixels. Note that the left-right direction in FIG.

  For example, the image data PG hatched in FIG. 15 is supplied to the hatched sub-pixel 35 in the display panel 31 shown in FIG. Since the inclination of the arrangement of the image data PG is the same as the inclination of the sub-pixels 35 in the arrangement direction, it is possible to display an image in the same state as when the subject is recorded.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The display device 30 includes a cylindrical display panel 31 in which a plate-shaped display panel 31 is curved. The shape of the plate-shaped display panel 31 is, for example, a parallelogram. In the display panel 31, terminal portions 33 and 34 are formed along a pair of sides 31a and 31b, and terminal portions are formed on the other pair of sides 31c and 31d. Not. The cylindrical display panel 31 is formed by bending the plate-shaped display panel 31 so that a pair of sides 31c and 31d on which terminal portions are not formed abut each other.

  The display panel 31 has a plurality of subpixels 35. The sub-pixels 35 are arranged along two arrangement axes AX and AY that extend along the surface of the display panel 31 on a plane and intersect each other. For example, the array axis AX and the array axis AY are set to be orthogonal to each other. The array axis AX is set so as to form a predetermined angle with respect to the side 31a where the terminal portion 33 of the display panel 31 is formed.

  The display panel 31 is supplied with a driving voltage to each sub-pixel 35 via terminals TX and TY formed on the terminal portions 33 and 34 and electrodes DX and DY. Therefore, in the cylindrical display panel 31, the arrangement interval L1 between the sub-pixels 35 sandwiching the sides 31c and 31d that are in contact with each other is substantially equal to the arrangement interval L2 between the two sub-pixels 35 formed in the other part. Therefore, the display panel 31 provides a visual, continuous all-around image in the displayed image. Thereby, the fall of the recognizability of a surrounding image can be suppressed.

  (2) The display system includes the imaging device 10 that outputs an all-around image. The image pickup device 13 of the image pickup apparatus 10 is tilted and fixed according to the tilt of the arrangement of the sub-pixels 35 of the display panel 31. The imaging device 10 rotates the imaging unit 12 by the drive unit 11, scans the imaging element 13 at every predetermined angle, and outputs image data RG corresponding to the entire surrounding image. The arrangement of the pixel data PG included in the image data RG corresponds to the arrangement of the sub-pixels 35 of the display panel 31. Therefore, it is possible to display an image in the same state as when the subject is recorded.

  (3) The image data processing unit 22 arranges a plurality of pixel data PG extracted from the block image data BG output from the imaging device 10 according to the display unit 32 of the display panel 31 and stores them in the memory 25. Thereby, image data corresponding to the display panel 31 can be efficiently recorded in the memory 25.

  Then, the image data processing unit 22 converts the array (coordinate values (Bx, By)) of the image data (pixel data PG) read from the memory 25 into coordinate values (Cx, Cy) corresponding to the display panel 31. Output. The coordinate values (Cx, Cy) of the pixel data PG after conversion correspond to the positions of the electrodes DX, DY included in the display panel 31. Thereby, an image corresponding to the image data read from the memory 25 can be efficiently obtained on the display panel 31.

In addition, you may implement each said embodiment in the following aspects.
In the above embodiment, the angle of the array axis AY in which the sub-pixels 35 are arranged in the display panel may be changed as appropriate. Further, the angle between the array axis AY and the array axis AX may be appropriately changed.

  In the above embodiment, the sensor interface 21 shown in FIG. 1 may output one line data at a predetermined position among image data obtained by one photographing.

  In the above embodiment, the cylindrical display panel 31 is formed in a circular shape when viewed from the support shaft direction, but the shape may be changed as appropriate. For example, an elliptical shape, a cylindrical shape having a flat surface in part (for example, a polygonal shape (triangle, quadrangle, pentagon, etc.), a semicircular shape, a fan shape, etc.) with chamfered corners may be used.

In the above embodiment, the display panel 31 is a liquid crystal display panel, but may be changed as appropriate. For example, an organic EL display panel may be used.
-The display panel 31 of the said embodiment can be used for what looks directly at the image displayed on the display panel, or what projects an image on a cylindrical screen or a wall surface. For example, it may be used as a light valve for a projector.

  The effective pixel data EG included in each block image data BG may be stored in the memory 25 without arranging the pixel data. In this case, when image data is read from the memory 25 for image display, coordinate offsets may be performed for each number of lines of line data included in the block image data BG.

  The valid pixel data EG and the invalid pixel data VG may be stored in the memory 25. In this case, when the image data is read from the memory 25 for image display, it is preferable to perform coordinate offset for the read effective pixel data EG for each number of line data columns included in the block image data BG. .
