Embodiments for Carrying Out the Invention

[0014] Next, embodiments of the present invention will be described with reference to the drawings. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. In the present disclosure, directions such as left, right, up, and down are directions with respect to the viewpoint.

[0015] (Wide-view display device) The wide-view display device 1 of the present disclosure is, for example, a head-mounted display. The user wears the wide-view display device 1 on the eyes to view the content data. The wide-view display device 1 has a size that can be worn on the user's eyes and realizes a wider viewing angle in the left-right direction than in the past.

[0016] The wide-field display device 1 is formed symmetrically. This disclosure describes the configuration of the right side of the wide-field display device 1 with respect to viewpoint E.

[0017] As shown in Figures 1 and 2, the wide-field display device 1 comprises a display unit 10 that displays input image data and an optical element 20 that reflects light emitted from the display unit 10. The optical element 20 is, for example, a mirror.

[0018] The input image data is data displayed by the wide-view display device 1 to allow the user to view the content data. In this disclosure, the content data has a wide field of view in the left-right direction. The input image data is data displayed by the display unit 10 to allow the user to view the content data. The input image data conforms to the size of the display unit 10.

[0019] The display unit 10 comprises a central display unit 11 and side display units 12. The central display unit 11 and side display units 12 are visible from viewpoint E.

[0020] The central display unit 11 is located on the central side of viewpoint E. The central display unit 11 displays the main content data in the left-right central part of the content data. In the example shown in Figure 1, the main content data is "A".

[0021] The side display unit 12 is located to the side of the central display unit 11. In Figure 2, the side display unit 12 is located to the right of the central display unit 11.

[0022] The side display unit 12 displays the first sub-content data to the side of the main content data at a first emission angle visible from viewpoint E. The side display unit 12 displays the second sub-content data to the side of the first sub-content data at a second emission angle. In the example shown in Figure 1, the first sub-content data is "B" and the second sub-content data is "C".

[0023] In this disclosure, the "first emission angle" and the "second emission angle" are emission angles as viewed from the side display unit 12. The "first emission angle" indicates the direction of viewpoint E as viewed from the side display unit 12. The "second emission angle" is the direction of the optical element 20 as viewed from the side display unit 12. Each pixel of the side display unit 12 emits light in a predetermined direction according to the mechanism for displaying different content data in multiple directions, and the specifications of the display unit 10 and optical element 20 in the wide-field display device 1.

[0024] The first and second emission angles are formed on a horizontal plane passing through the viewpoint E. In the example shown in Figure 1, the first emission angle is the angle from the side display unit 12 toward the viewpoint E. The user can directly see the light emitted from the side display unit 12 at the first emission angle.

[0025] The second emission angle is the angle from the display unit 10 toward the optical element 20. The second emission angle is an angle that is directed sideways more than the first emission angle. In the example shown in Figures 1 and 2, the second emission angle is the angle from the side display unit 12 toward the optical element 20. In some cases, the user may not be able to directly see the light emitted from the side display unit 12 at the second emission angle. Therefore, the wide-field display device 1 is provided with an optical element 20. The optical element 20 directs the light emitted at the second emission angle into the viewpoint E. The user can see the light emitted from the side display unit 12 at the second emission angle as a virtual image formed by the reflection of the optical element 20. The user recognizes the virtual image formed by the reflection of the optical element 20 as the image displayed by the virtual surface 20v in Figure 1.

[0026] Here, the second sub-content data that the user views is in a state that has been horizontally inverted by the optical element 20. The side display unit 12 displays the horizontally inverted data of the second sub-content data.

[0027] The side display section 12 of this disclosure is formed by providing a lenticular lens on its surface. Different content data is displayed at the first and second emission angles. The side display section 12 can be formed in any way that enables it to display different content data at the first and second emission angles.

[0028] Refer to Figure 3 to explain the directivity in a light field display. In this disclosure, the side display section 12 uses a lenticular lens to display different content data in two directions. Figure 3 illustrates the case where two content data "A" and "B" are displayed in two directions, but the same applies when three or more content data are displayed in three or more directions.

[0029] As shown at the bottom of Figure 3, the side display unit 12 displays input image data in which multiple partial content data, each of the first sub-content data and the second sub-content data, are cut into strips and arranged alternately. Here, the shape of the strips is such that the shorter side is the left-right direction with respect to the viewpoint E, and the longer side is the up-down direction with respect to the viewpoint E. The input image data is arranged from left to right, with the strip portions relating to the first sub-content data and the strip portions relating to the second sub-content data arranged alternately.

[0030] The side display unit 12 directs the portion of the input image data relating to the first sub-content data to the first viewpoint E1 using a lenticular lens. The side display unit 12 also directs the portion of the input image data relating to the second sub-content data to the second viewpoint E2 using a lenticular lens. This allows different content data to be displayed in two different directions.

[0031] The central display unit 11 displays one content data per unit area, while the side display units 12 display two content data per unit area. The resolution of the content data displayed by the side display units 12 is lower than the resolution of the content data displayed by the central display unit 11.

[0032] Generally, the human field of vision is divided into an effective field of vision with an internal angle of about 60 degrees and a peripheral field of vision that covers the rest. The effective field of vision is the range in which the brain can perceive things almost clearly, while the peripheral field of vision is the range in which the shape and color of objects cannot be clearly perceived. Therefore, even if the side display unit 12 displays low-resolution content data, it will not have a significant impact on the user's perception.

[0033] In this disclosure, the side display unit 12 is described in the case where a lenticular lens is used, but other technologies such as a parallax barrier may also be used. In this disclosure, the side display unit 12 is described in the case where it displays different content data for multiple emission angles formed on a plane perpendicular to the display unit 10, but is not limited to this. The side display unit 12 may display different content data for emission angles in any direction relative to the display unit 10.

[0034] The user views the main content data and the first sub-content data on the display unit 10, and views the second sub-content data via the first optical element 20. This allows for viewing of content data with a wider field of view compared to a display device consisting only of the display unit 10.

[0035] The wide-view display device 1 has a mechanism in which the side display units 12 of the display unit 10 display different content data at multiple emission angles, and optical elements 20 mounted on the wide-view display device 1 enable the display of different content data to the user at each angle. The wide-view display device 1 is a compact mechanism using a general-purpose display that can achieve a wide field of view, thus reducing the burden on the user.

[0036] (First variation) Referring to Figure 4, the first modified wide-field display device 1a will be described. The first modified wide-field display device 1a achieves a wider field of view compared to the wide-field display device 1 described with reference to Figure 1.

[0037] The wide-field display device 1a comprises a display unit 10, a first optical element 20, and a second optical element 30.

[0038] The side display section 12a of the wide-field display device 1a displays the first sub-content data at the first emission angle, the second sub-content data at the second emission angle, and the third sub-content data at the third emission angle. The first optical member 20 directs the second sub-content data into the viewpoint E. The second optical member 30 directs the light emitted at the third emission angle into the viewpoint E.

[0039] Of the three sub-content data displayed by the side display unit 12a, the light from the first sub-content data is incident directly on viewpoint E. The light from the second sub-content data is reflected by the first optical member 20 before being incident on viewpoint E. The light from the third sub-content data is reflected by the second optical member 30 before being incident on viewpoint E.

[0040] In Figure 4, when light emitted from the side display section 12b at a third emission angle and reaching the direction of the second optical member 30 is incident on the first optical member 20, the first optical member 20 is formed of a half mirror. Specifically, the first optical member 20 receives light emitted at the second emission angle as incident on the viewpoint E and transmits light emitted at the third emission angle. The light emitted at the third emission angle, after passing through the first optical member 20, is reflected by the second optical member 30 and incident on the viewpoint E.

[0041] The second optical element 30 is located behind the first optical element 20 relative to the display unit 10. Light incident on the second optical element 30 from the display unit 10 passes through the first optical element 20. Therefore, the optical element 20 of the first modified example is formed from a half-mirror. A half-mirror reflects some of the light and transmits some of the light.

[0042] The user views the main content data and the first sub-content data from the display unit 10, the second sub-content data through the first optical member 20, and the third sub-content data through the second optical member 30. The first modified wide-field display device 1a allows for viewing of wider-field content data compared to the wide-field display device 1 of this disclosure.

[0043] The first modified wide-field display device 1a shown in Figure 4 achieves a field of view of 162 degrees. The distances and coordinates shown in Figure 4 are examples. The display unit 10 is formed 7 cm away from the viewpoint E. The second optical element 30 is formed 7.65 cm to the side of the viewpoint E. Therefore, the mechanism of the first modified device can be incorporated into a head-mounted display worn by the user.

[0044] Referring to Figure 5, the field of view when a user wears and views the first modified wide-field display device 1a will be explained. The user views the central display unit 11, the side display units 12, the first optical element 20, and the second optical element 30. The central display unit 11, the side display units 12, the first optical element 20, and the second optical element 30 are formed to be wide in the left-right direction so as to cover the viewpoint E.

[0045] The central display unit 11 displays "A" of the main content data. The side display unit 12 displays "B" of the first sub-content data. The first optical element 20 projects "C" of the second sub-content data onto the first virtual surface 20v. The second optical element 30 projects "D" of the third sub-content data onto the second virtual surface 30v.

[0046] The central display unit 11, the side display units 12, the first optical element 20, and the second optical element 30 are formed to be wide in the circumferential direction so as to cover the viewpoint E. The user can view content data with a wide field of view. The wide-field display device 1a can achieve a high level of immersion.

[0047] (Second variation) Referring to Figure 6, a second modified example of the wide-field display device 1b will be described. The second modified example of the wide-field display device 1a achieves a wider field of view compared to the first modified example of the wide-field display device 1a described with reference to Figure 2.

[0048] The wide-field display device 1b comprises a display unit 10, a first optical element 20, a second optical element 30, and a third optical element 40.

[0049] The side display section 12b of the wide-field display device 1b displays the first sub-content data at the first emission angle, the second sub-content data at the second emission angle, the third sub-content data at the third emission angle, and the fourth sub-content data at the fourth emission angle. The first optical member 20 directs the light of the second sub-content data emitted at the second emission angle onto the viewpoint E. The second optical member 30 directs the light of the third sub-content data emitted at the third emission angle onto the viewpoint E. The third optical member 40 directs the light of the fourth sub-content data emitted at the fourth emission angle onto the viewpoint E.

[0050] The second modified wide-field display device 2a shown in Figure 6 achieves a field of view of 192 degrees. The distances and coordinates shown in Figure 6 are examples. The positions of the first optical member 20 and the second optical member 30 of the second modified wide-field display device 1b are the same in the left-right direction as the position of the first optical member 20 of the first modified wide-field display device 1a. Furthermore, although the third optical member 40 is located behind the viewpoint E, considering the shape of the face, it is possible to position the third optical member 40 around the eyes. Therefore, the mechanism of the second modified device can be incorporated into a head-mounted display worn by the user.

[0051] The user views the main content data and the first sub-content data from the display unit 10, the second sub-content data via the first optical member 20, the third sub-content data via the second optical member 30, and the fourth sub-content data via the third optical member 40. The second modified wide-field display device 1b allows for viewing of wider-field content data compared to the first modified wide-field display device 1a. Furthermore, an even wider field of view can be achieved by increasing the number of mirrors or spreading the arrangement of mirrors further in the circumferential direction.

[0052] (Display system) The display system 100 of this disclosure will be described with reference to Figure 7. The display system 100 comprises a wide-field display device 1 and a processing device 50. The wide-field display device 1 may be a first modified example of a wide-field display device 1a, or a second modified example of a wide-field display device 1b, etc.

[0053] Here, we will describe a case where the display system 100 includes a wide-field display device 1a of the first modified example shown in Figure 4, and the content data viewed by the user is the data shown in Figure 5. The wide-field display device 1a of the first modified example includes two optical members 20 and 30. The content data includes main content data and first to third sub-content data.

[0054] As shown in Figures 7 and 26, the processing unit 50 includes image data G1, segmented image group data G2, processed image group data G3, and input image data G4, as well as the functions of a segmentation unit 51, a processing unit 52, and a synthesis unit 53. Each data is stored in a storage device such as memory 902 or storage 903. Each function is implemented in the CPU 901.

[0055] Image data G1 is the source data for the content data that is presented to the user. Image data G1 has a wide field of view in the left-right direction. While there may be differences in resolution, display angle, brightness, etc., between image data G1 and the content data perceived by the user, particularly on the sides, the composition at least matches.

[0056] As shown in Figure 8, the image data G1 comprises a main image data section G11, a first sub-image data section G12, a second sub-image data section G13, and a third sub-image data section G14. The main image data section G11 corresponds to the main content data. The first sub-image data section G12 corresponds to the first sub-content data. The second sub-image data section G13 corresponds to the second sub-content data. The third sub-image data section G14 corresponds to the third sub-content data. The shapes of G11-G14 follow the configuration of the wide-view display device 1a.

[0057] As shown in Figure 9, the segmented image data G2 comprises the main image data G21, the first sub-image data G22, the second sub-image data G23, and the third sub-image data G24. Here, the second sub-image data G23 is data obtained by horizontally inverting the second sub-image data portion G13 of the image data G1. The third sub-image data G24 is data obtained by horizontally inverting the third sub-image data portion G14 of the image data G1.

[0058] The processed image data G3 is data obtained by processing the first sub-image data G22, the second sub-image data G23, and the third sub-image data G24 from the divided image data G2, so that they can be displayed at a predetermined emission angle.

[0059] As shown in Figure 10, the processed image data set G3 comprises the main image data G31, the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34. The first sub-image data G32, the second sub-image data G33, and the third sub-image data G34 are data obtained by downsampling the vertical pixel groups to 1 / 3 from the first sub-image data G22, the second sub-image data G23, and the third sub-image data G24 in Figure 9, respectively, in order to achieve directionality in a light field display.

[0060] Input image data G4 is data created by combining processed image data G3 to achieve directionality in a light field display.

[0061] As shown in Figure 11, the input image data G4 comprises a main image data section G41 and a sub-image data section G42. The main image data section G41 is the same as the main image data G31 of the processed image data group G3. The sub-image data section G42 is data obtained by superimposing the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34 of the processed image data group G3.

[0062] The division unit 51 divides the image data G1 displayed to the user into a main image data portion in the center in the left-right direction, a first sub-image data portion on the side of the main image data, a second sub-image data portion on the side of the first sub-image data portion, and a third sub-image data portion on the side of the second sub-image data portion. Furthermore, the division unit 51 reverses the second sub-image data and the third sub-image data portions horizontally.

[0063] The segmented image data G2 generated by the segmentation unit 51 includes the main image data G21, the first sub-image data G22, the second sub-image data G23 which is horizontally flipped, and the third sub-image data G24 which is horizontally flipped.

[0064] The processing unit 52 generates processed image data G3 from the segmented image data G2. From the segmented image data G2, the processing unit 52 thins out the vertical pixel groups by 1 / 3 from each of the image data that enables directionality in the light field display, specifically the first sub-image data G22, the second sub-image data G23, and the third sub-image data G24 in Figure 9, to generate the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34 in Figure 10. The processing unit 52 converts the main image data G21 into main image data G31. Here, the method for generating image data that enables directionality in the light field display follows the configuration adopted by the wide-field display device 1.

[0065] The processed image data G3 generated by the processing unit 52 includes the main image data G31, the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34.

[0066] The synthesis unit 53 synthesizes the processed image data G3 to generate input image data G4. The synthesis unit 53 uses the main image data G31 as the main image data unit G41. The synthesis unit 53 superimposes the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34 to generate a sub-image data unit G42. The synthesis unit 53 combines the main image data unit G41 and the sub-image data unit G42 to generate input image data G4. Here, the synthesis method for each data unit follows the directional configuration adopted by the wide-field display device 1.

[0067] (Processing method) Referring to Figure 12, the method for generating input image data G4 by the processing unit 50 will be explained.

[0068] In step S1, the processing unit 50 divides the image data G1 in the left-right direction into the number of optical members, specifically the number of mirrors + 2, to generate divided image group data G2. In the first modified example, the wide-field display device 1a is equipped with two mirrors, so the processing unit 50 divides the image data G1 into four parts. Here, the size of the divisions follows the specifications of the wide-field display device 1a.

[0069] In step S2, the processing unit 50 horizontally flips the images corresponding to the number of mirrors on the side of the divided image data G2. The processing unit 50 horizontally flips the two images on the side of the divided image data G2. This is because these images are reflected by the mirrors and are visible to the user.

[0070] In step S3, the processing device 50 processes the images to be displayed on the side display unit 12 from the segmented image data G2 for multi-viewpoint use to generate processed image data G3. The processing for multi-viewpoint use follows the specifications of the wide-field display device 1a. For example, the processing device 50 reduces the vertical pixel group by 1 / 3 from each of the first sub-image data G22, second sub-image data G23, and third sub-image data G24 in Figure 9 to generate the first sub-image data G32, second sub-image data G33, and third sub-image data G34 in Figure 10.

[0071] In step S4, the processing device 50 synthesizes the processed image data G3 to generate input image data G4. For example, the processing device 50 superimposes the first sub-image data G32, the second sub-image data G33, and the third sub-image data G34, and concatenates the superimposed image data with the main image data to generate input image data G4.

[0072] Note that the content and sequence of the process shown in Figure 12 are just an example and are not limited to this.

[0073] Furthermore, the processing unit 50 may adjust the color of each pixel of the input image data G4 in accordance with the specifications of the wide-field display device 1. Depending on the specifications of the wide-field display device 1, such as the size and angle of the optical elements and whether or not they are half-mirrors, the color seen by viewpoint E may differ from the color of the image data G1. Therefore, the processing unit 50 may adjust the color of each pixel of the input image data G4 in accordance with the specifications of the wide-field display device 1 so that the color seen by viewpoint E approaches the color of the image data G1.

[0074] (Third variation) The wide-field display device 1, the first modified wide-field display device 1a, and the second wide-field display device 1b of the present disclosure are provided with means for realizing a predetermined directivity in the side display section 12 of the display section 10, and utilize an optical member 20 provided on the side of the display section 10 to achieve a wide field of view.

[0075] In the third modified example, with reference to Figures 13-17, a case will be described in which the part of the display unit 10 that provides the means for achieving directionality is arbitrary. The display unit 10 displays input image data for the user to view the content data.

[0076] In the third modified example, the display unit 10c includes a non-multi-viewpoint region 15 and a multi-viewpoint region 16. The non-multi-viewpoint region 15 and the multi-viewpoint region 16 are distinguished by whether or not means for achieving directionality are provided. The non-multi-viewpoint region 15 is the part of the display unit 10 in which means for achieving directionality are not provided. The multi-viewpoint region 16 is the part of the display unit 10 in which means for achieving directionality are provided.

[0077] The means of achieving directionality will be explained using a lenticular lens as an example. A lenticular lens is provided on the front surface of the multi-viewpoint region 16. The front surface is the surface opposite the viewpoint.

[0078] The display unit 10c comprises a first display unit 17 and a second display unit 18. The first display unit 17 and the second display unit 18 differ in that the emitted light passes through the optical member 20 before entering the viewpoint. The first display unit 17 emits light that enters the viewpoint without passing through the optical member 20. The second display unit 18 emits light that is reflected by the optical member 20 before entering the viewpoint.

[0079] In the display unit 10c shown in Figure 13, the non-multi-viewpoint area 15 is located in the center of the display unit 10c in the vertical direction. The multi-viewpoint areas 16 are located above and below the non-multi-viewpoint area 15, respectively.

[0080] The non-multi-viewpoint region 15 has a function corresponding to the central display unit 11 in the display unit 10 shown in Figures 1 and 2. The non-multi-viewpoint region 15 is the part for displaying the main content data "A" in the display unit 10 of this disclosure shown in Figure 1. Since the non-multi-viewpoint region 15 is not provided with means for realizing directionality, the non-multi-viewpoint region 15 is the first display unit 17, which emits light incident on the viewpoint.

[0081] The multi-view area 16 has a function corresponding to the side display area 12 in the display unit 10 shown in Figures 1 and 2. The multi-view area 16 comprises a first display area 17 and a second display area 18.

[0082] The first display unit 17 in the multi-view region 16 is the part of the multi-view region 16 that emits light incident on the viewpoint. The first display unit 17 in the multi-view region 16 is the part of the display unit 10 of this disclosure shown in Figure 1 that displays the first sub-content data "B". Since the first display unit 17 is provided with a lenticular lens, the light emitted from the first display unit 17 is incident on the viewpoint via the lenticular lens.

[0083] The second display unit 18 is the part of the multi-viewpoint region 16 that emits light that is reflected by the optical member 20 and incident on the viewpoint. The second display unit 18 is the part of the display unit 10 of this disclosure shown in Figure 1 that displays the second sub-content data "C". Since the second display unit 18 is provided with a lenticular lens, the light emitted from the second display unit 18 is incident on the optical member 20 via the lenticular lens, and the light reflected from the optical member 20 is incident on the viewpoint.

[0084] The display unit 10c shown in Figure 13 is used, for example, in the wide-view display device 1c shown in Figure 14. As shown in Figure 14, the wide-view display device 1c is provided with optical members 20 above and below the display unit 10c. The optical members 20 reflect the light emitted from the display unit 10c.

[0085] The second display unit 18 achieves directionality by emitting light in the direction of the optical element 20. Of the second display unit 18, the portion above the non-multi-viewpoint region 15 emits light in the direction of the optical element 20 above the display unit 10c. Of the second display unit 18, the portion below the non-multi-viewpoint region 15 emits light in the direction of the optical element 20 below the display unit 10c.

[0086] The second display unit 18 is formed in the direction in which the optical member 20 is formed. As shown in Figure 14, the optical member 20 is formed in the vertical direction of the display unit 10c, so the second display unit 18 is formed in the vertical direction of the display unit 10c.

[0087] The wide-view display device 1c shown in Figures 13-14 is the same as the wide-view display device 1 described with reference to Figure 1-2, but with the direction in which the multi-viewpoint area 16 is provided changed from the left-right direction to the up-down direction. The wide-view display device 1c can achieve a wide field of view in the up-down direction from a viewpoint provided in the X-axis direction.

[0088] The wide-view display device 1c shown in Figure 14 has one optical element 20 at the top and one at the bottom, but it may also have two optical elements 20 and two optical elements 30 at the top and bottom, as shown in the wide-view display device 1c' shown in Figure 15. The display unit 10c' used in the wide-view display device 1c' has a multi-view region 16' in the vertical direction. The multi-view region 16' includes a first display unit 17, a second display unit 18, and a third display unit 19. The first display unit 17 and the second display unit 18 are as described with reference to Figures 13-14.

[0089] The third display unit 19 is the portion of the multi-viewpoint region 16' that emits light that is reflected by the optical member 30 and incident on the viewpoint. Since the third display unit 19 is provided with a lenticular lens, the light emitted from the third display unit 19 is incident on the optical member 30 via the lenticular lens, and the light reflected from the optical member 30 is incident on the viewpoint. When the light incident on the optical member 30 from the third display unit 19 passes through the optical member 20, at least the portion of the optical member 20 that the light incident on the optical member 30 from the third display unit 19 passes through is formed of a half mirror.

[0090] The third display unit 19 provides directivity by directing light in the direction of the optical element 30. As shown in Figure 15, the optical element 30 is formed in the vertical direction of the display unit 10c', so the third display unit 19 is formed in the vertical direction of the display unit 10c'.

[0091] The third display unit 19 is formed in the direction in which the optical member 30 is formed. As shown in Figure 15, the optical member 30 is formed in the vertical direction of the display unit 10c', so the third display unit 19 is formed in the vertical direction of the display unit 10c'.

[0092] The wide-view display device 1c' shown in Figure 15 is a modified version of the wide-view display device 1a described with reference to Figure 4, in which the direction in which the multi-viewpoint area is provided is changed from the left-right direction to the up-down direction. The wide-view display device 1c' can achieve a wide field of view in the vertical direction from a viewpoint provided in the X-axis direction. Furthermore, the wide-view display device 1c' achieves an even wider field of view in the vertical direction compared to the wide-view display device 1c shown in Figure 14.

[0093] In the display unit 10d shown in Figure 16, a non-multi-viewpoint area 15 is formed in the central part, and multi-viewpoint areas 16 are formed at the four corners of the display unit 10d. Each multi-viewpoint area 16 shown in Figure 16 has the shape of a right triangle, but the shape is not limited.

[0094] The non-multi-view region 15 forms the first display unit 17. The multi-view region 16 includes the first display unit 17 and the second display unit 18.

[0095] The display unit 10d shown in Figure 16 is applied, for example, to a wide-field display device having optical members 20 in the left, right, top, and bottom corners of the display unit 10d. The second display unit 18 provides directivity in which light is incident in the direction of the optical members 20. The second display unit 18 is formed in the direction in which the optical members 20 are formed. Optical members 20 are provided in the direction of the four corners of the display unit 10d.

[0096] The display unit 10d shown in Figure 16 can achieve a wide field of view in the four corners: left, right, top, and bottom. When the field of view is expanded in each of the four corners, it is possible that the expanded fields of view at adjacent corners in the circumferential direction may connect. If the field of view realized by the upper left multi-view region 16 connects with the fields of view realized by the lower left and upper right multi-view regions 16, and the field of view realized by the lower right multi-view region 16 connects with the fields of view realized by the upper right and lower left multi-view regions 16, then a wide field of view can be achieved in the circumferential direction of the display unit 10d. A wide-field display device to which the display unit 10d is applied can achieve a field of view wider than the plane of the display unit 10d in the YZ plane.

[0097] In the display unit 10e shown in Figure 17, a non-multi-viewpoint area 15 is formed in the central part, and multi-viewpoint areas 16 are formed along the four sides (left, right, top, and bottom) of the display unit 10e. Each multi-viewpoint area 16 shown in Figure 17 has a rectangular shape with a central rectangle cut out, but the shape is not limited.

[0098] The display unit 10e shown in Figure 17 is applied to a wide-field display device 1e having an optical member 20 in the circumferential direction. The second display unit 18 provides directivity by directing light in the direction of the optical member 20. The second display unit 18 is formed in the direction in which the optical member 20 is formed.

[0099] For example, if the wide-field display device 1e is a head-mounted display, the optical member 20 is formed between the display unit 10e and the user's head when the head-mounted display is worn.

[0100] The wide-view display device 1e shown in Figure 17 can achieve a wide field of view in the circumferential direction of the display unit 10e. The wide-view display device 1e can achieve a field of view wider than the surface of the display unit 10e in the YZ plane.

[0101] (Fourth variation) In the third modified example, a case was described in which the portion of the display unit 10 that is provided with means for achieving directionality is arbitrary. In the fourth modified example, a case is described in which the entire display unit 10 is provided with means for achieving directionality.

[0102] As shown in Figure 18, a multi-viewpoint area 16 is formed across the entire display surface of the display unit 10f. Viewpoints E1, E2, and E3, shown in Figure 19, allow for the viewing of different content when observing the display unit 10f. A means of achieving directionality will be explained using a lenticular lens as an example.

[0103] The multi-viewpoint region 16 includes a first display unit 17 and a second display unit 18, as described in the third modified example. In the fourth modified example, the first display unit 17 includes a means having directionality for incident light in the direction of the viewpoint.

[0104] The first display unit 17 is the part of the display unit 10f that emits light that is incident on the viewpoint. The light emitted from the first display unit 17 is incident on the viewpoint via a lenticular lens. The second display unit 18 is the part of the display unit 10f that emits light that is reflected by the optical element 20 and incident on the viewpoint. The light emitted from the second display unit 18 is incident on the optical element 20 via a lenticular lens, and the light reflected from the optical element 20 is incident on the viewpoint.

[0105] In the fourth modified example, the first display unit 17 and the second display unit 18 are provided across the entire display surface of the display unit 10f. However, for reasons such as accuracy or specifications, a lenticular lens may not be provided on a portion of the display unit 10f.

[0106] The positions of the first display unit 17 and the second display unit 18 depend on the specifications of the means for achieving directivity and the positional relationship between each display unit and the viewpoint. The first display unit 17 and the second display unit 18 may be provided discretely on a pixel-by-pixel basis or in units of multiple pixels. The first display unit 17 and the second display unit 18 may be provided so as to divide the display surface of the display unit 10f in two.

[0107] In the fourth modified example, the optical member 20 is formed around the display unit 10f when viewed from the viewpoint. As shown in Figure 20, when the display unit 10f is observed from the front, the display unit 10f achieves directionality to the left, so the optical member 20 is provided on the left side of the display unit 10f.

[0108] Referring to Figure 20, we will explain the case where a lenticular lens is used to achieve directionality in Figure 19. Figure 20(a) is a view of the xz plane (cross-section in the Z direction of the YZ plane) of the display unit 10f, and Figure 20(b) is a perspective view of the display unit 10f.

[0109] As shown in Figure 20(a), multiple lenticular lenses L are arranged in the Z-axis direction on the viewpoint side of the display unit 10f, such that the convex portion of the lenticular lens L is in the Y-axis direction. In this case, the first display unit 17 emits light towards the viewpoint. The second display unit 18 emits light in the direction of the optical member 20 provided on the left side of the display unit 10f, forming a virtual image on the virtual plane 20v.

[0110] Figure 21(a) shows the orientation and direction of directivity of the lenticular lens L shown in Figure 19. In the case of the lens orientation shown in Figure 20, the direction of directivity is to the left when the display unit 10f is observed from the front. Therefore, as shown in Figure 19, the optical element 20 is provided on the left side of the display unit 10f.

[0111] As another example, when the display unit 10f in Figure 19 is observed from the front, if the lenticular lens achieves directionality in both the left and right directions, optical members 20 are provided on both the left and right sides of the display unit 10f.

[0112] The width of the optical element 20 (length in the X direction in Figure 19) may differ depending on whether directivity is achieved in both left and right directions, or in only one of the left or right directions. When a multi-viewpoint area 16 is provided across the entire display surface of the display unit 10f and a virtual image is formed with the same resolution, the width of the optical element 20 when directivity is provided in either the left or right direction is larger than when directivity is provided in both left and right directions. This is because light from the second display unit 18 of the entire display unit 10f is incident on a single optical element 20.

[0113] Figure 21(b) shows yet another example in which multiple lenticular lenses L are arranged in the Y-axis direction on the viewpoint side of the display unit 10g, such that the convex portion of the lenticular lens L is in the Z-axis direction. In this case, the direction of directivity is achieved in the vertical direction when the display unit 10f is observed from the front. In this case, as shown in the wide-field display device 1g of Figure 22, the optical members 20 are provided on the upper and lower sides when the display unit 10g is observed from the front.

[0114] If the orientation of the lenticular lens L is as shown in Figure 21(b), and directivity is achieved on the upper side but not on the lower side, the optical element 20 is located on the upper side and not on the lower side when the display unit 10g is observed from the front. Similarly, if directivity is achieved on the lower side but not on the upper side, the optical element 20 is located on the lower side and not on the upper side when the display unit 10g is observed from the front.

[0115] (Fifth variation) The fifth modified example, the display unit 10h shown in Figure 23, shares the same characteristics as the fourth modified example in that a multi-viewpoint region 16 is formed across the entire display unit 10h, but the position of the optical member 20 is different. In the above disclosure and each modified example, the optical member 20 is formed around the display unit 10 as seen from the viewpoint, so that the optical member 20 is not intercepted when viewing the display unit 10 from the viewpoint.

[0116] In contrast, in the fifth modified example, the wide-field display device 1h, the optical member 20 is formed between the viewpoint and the display unit 10h. In the wide-field display device 1h, the optical member 20 has mirrors on both sides. The optical member 20 is located at the center of the display unit 10h in the left-right direction. The optical member 20 is located between the left and right viewpoints.

[0117] More specifically, the wide-view display device 1h is formed such that the surface forming the thickness of the optical element 20 is in contact with or close to the display unit 10h, and the mirror surface of the optical element 20 is perpendicular to the display unit 10h.

[0118] Generally, the display unit 10 displays the right-eye image on the right side corresponding to the right eye, and the left-eye image on the left side corresponding to the left eye. This allows the user to view the left-eye image with their left eye and the right-eye image with their right eye when they turn their eyes inward.

[0119] In contrast, the fifth modified example, the wide-field display device 1h, has an optical element 20 placed between the left and right eyes. The optical element 20 has mirrors on both sides and is non-transparent or has low transparency. As shown in Figure 24, the optical element 20 reflects the light of the left-eye image on the left side and incident on the left eye, and reflects the light of the right-eye image on the right side and incident on the right eye. This makes it possible for the display unit 10h to widen the field of view inward.

[0120] Figures 23-24 illustrate the case where the multi-viewpoint region 16 is formed over the entire display unit 10h, but the design is not limited to this. For example, the multi-viewpoint region 16 may be formed only in the vicinity of the part of the display unit 10h that is in contact with the optical element 20. In addition to the multi-viewpoint region 16, the display unit 10h may also include a non-multi-viewpoint region 15. In Figures 23-24, the position of the optical element 20 may be shifted to the right or left. In Figures 23-24, the optical element 20 is provided from the top edge to the bottom edge of the display unit 10h, but it may also be provided only in a portion of it.

[0121] Figures 23-24 illustrate the case where the optical member 20 is positioned vertically with respect to the viewpoint, but the case is not limited to this. As shown in Figure 25, the mirror surface of the optical member 20 may be formed to be parallel to the plane connecting the two lines of sight.

[0122] The wide-field display device 1i has an optical element 20 on the plane connecting the left and right viewpoints. The optical element 20 has mirrors on both sides and is non-transparent or has low transparency. As shown in Figure 25, the optical element 20 reflects light emitted from the upper side of the left and right eyes and incident on the upper side of the viewpoint, and reflects light emitted from the lower side of the left and right eyes and incident on the lower side of the viewpoint.

[0123] Figure 25 illustrates a case where the multi-viewpoint region 16 is formed over the entire display unit 10i, but it is not limited to this. For example, the multi-viewpoint region 16 may be formed only in the vicinity of the part of the display unit 10i that is in contact with the optical element 20. In addition to the multi-viewpoint region 16, the display unit 10i may also include a non-multi-viewpoint region 15. In Figure 25, the position of the optical element 20 may be shifted upward or downward.

[0124] Figures 23-25 ​​illustrate the case where the optical element 20 is provided in the display unit, but as explained with reference to Figure 1 and others, the optical element 20 may also be provided around the display unit.

[0125] Figures 23-25 ​​illustrate the case where the optical element 20 has mirrors on both sides, but it is also possible to have a mirror on only one side.

[0126] (Other variations) The description of the lenticular orientation as being parallel to one of the four sides of the display unit 10 has been made, but it is not limited to this. The lenticular orientation can be any direction, as long as the orientation of the lenticular and the positions of the first display unit 17 and the second display unit 18 formed below the lenticular are appropriate.

[0127] In the above examples, the wide-view display device was described as being formed symmetrically from left to right or up to down, but it is not limited to these cases. The wide-view display device may extend the field of view in only one direction (left to right) or only one direction (up to down). The wide-view display device may also achieve different fields of view in the left and right or up and down directions, such as the left field of view being wider than the right field of view.

[0128] Furthermore, the wide-field display device may be formed symmetrically with respect to any axis. The display device may also be formed asymmetrically with respect to any axis.

[0129] Although the wide-field display device described above includes one or two optical elements in one direction, it may also include three or more optical elements.

[0130] (A modified display system) In the display system 100 of this disclosure, the wide-field display device 1 is provided with means for realizing a predetermined directivity in the side display section 12 of the display unit 10, and a wide field of view is achieved by utilizing the optical member 20 provided on the side of the display unit 10.

[0131] On the other hand, in the third and subsequent modifications, it is possible to provide means for realizing directionality at any position on the display unit 10. Therefore, the processing device 50 may generate input image data G4 according to the position on the display unit 10 of the wide-field display device 1 where the means for realizing directionality is provided, and according to that directionality.

[0132] Specifically, the splitting unit 51 splits the image data G1 to be displayed to the user into a first image data to be displayed on the first display unit 17 and a second image data to be displayed on the second display unit 18. The split image data G2 includes the first image data and the second image data. The image data G1 (content data) to be displayed to the user includes the first image data and the second image data.

[0133] In the third and subsequent modifications, the first display unit 17 and the second display unit 18 may be formed consecutively or discretely. Both the first image data and the second image data may be data from a single block formed by multiple consecutive pixels of the image data G1, or they may be data from multiple blocks.

[0134] The processing unit 52 generates a second converted image data, which is converted from the second image data, so that the second image data can be displayed using the light reflected by the optical element 20. The second converted image data is generated by converting the second image data. The second converted image data is inverted in accordance with the direction of the optical element 20 relative to the second display unit 18. The processed image data group G3 includes the first image data and the second converted image data.

[0135] The second transformed image data, like the second image data, may be data from a single block formed by multiple consecutive pixels of the image data G1, or it may be data from multiple blocks. For example, in Figure 13 or Figure 16, the second display unit 18 is formed discretely, so the second transformed image data may be data from multiple blocks, corresponding to the number of second display units 18.

[0136] The synthesis unit 53 synthesizes the first image data and the second converted image data to generate input image data G4. The input image data G4 is displayed on the display unit 10. The input image data G4 includes the first image data and the second converted image data.

[0137] The processing unit 50 of this embodiment described above uses, for example, a general-purpose computer system comprising a CPU (Central Processing Unit, processor) 901, memory 902, storage 903 (HDD: Hard Disk Drive, SSD: Solid State Drive), communication device 904, input device 905, and output device 906. In this computer system, the CPU 901 executes a program loaded onto the memory 902, thereby realizing each function of the processing unit 50.

[0138] The processing unit 50 may be implemented on a single computer or on multiple computers. Furthermore, the processing unit 50 may be a virtual machine implemented on a computer.

[0139] The program of the processing unit 50 can be stored on computer-readable recording media such as HDDs, SSDs, USB (Universal Serial Bus) memory, CDs (Compact Discs), and DVDs (Digital Versatile Discs), or it can be distributed over a network.

[0140] It should be noted that the present invention is not limited to the embodiments described above, and numerous modifications are possible within the scope of its essence. [Explanation of Symbols]
