[0010] Hereinafter, embodiments of the present invention (hereinafter referred to as "this embodiment") will be described with reference to the drawings. In the following description, the head-mounted display, which is a display device, will be referred to as "HMD (Head Mounted Display)". In the following description, the directions indicated by X1 and X2 in the figure will be the right and left, respectively, the directions indicated by Y1 and Y2 in the figure will be the up and down, respectively, and the directions indicated by Z1 and Z2 in the figure will be the front and rear, respectively. Each of these directions indicates the direction as seen from the perspective of the user wearing the HMD 1.

[0011] [Overview of HMD1] Figure 1 is a perspective view showing the external appearance of the HMD according to this embodiment. The HMD1 preferably has a mounting band that surrounds the user's head and a main body housing supported at the front of the mounting band. The main body housing houses various components such as a display panel and optical system.

[0012] The HMD1 shown in Figure 1 is just one example and is not limited thereto. The HMD1 only needs to be worn on the user's head and have multiple display panels that display images, and the shape of the mounting band and main housing are not limited to those shown.

[0013] Figure 2 is a schematic diagram of the display panel and optical system configuration in this embodiment, viewed from the left. Figure 2 shows the display panel and optical system on the user's left eye side, but the configuration shown in Figure 2 may be provided on both the right and left eye sides.

[0014] The HMD1 includes a first display panel 10 and a second display panel 20, and an optical system including an optical mirror 30 and an eyepiece lens 40. Note that the optical system shown in Figure 2 is an example, and other optical components may be included.

[0015] [First display panel 10] The first display panel 10 may display a two-dimensional image or a three-dimensional image. The first display panel 10 may be, for example, an organic electroluminescent display panel.

[0016] [Second Display Panel 20] The second display panel 20 may display a two-dimensional or three-dimensional image. The second display panel 20 may be, for example, an organic electroluminescent display panel. The second display panel 20 may be capable of displaying an image with a higher resolution than the first display panel 10. In this embodiment, an example in which a microOLED (Organic Light-Emitting Diode) is used as the second display panel 20 will be described.

[0017] [Optical Mirror 30] The optical mirror 30 is preferably configured to transmit at least a portion of the first image light L1 emitted from the first display panel 10 and to reflect at least a portion of the second image light L2 emitted from the second display panel 20. For example, a half-mirror with a transmission-to-reflection ratio of 1:1 for light of a specific wavelength may be used as the optical mirror 30. However, the transmission-to-reflection ratio is not limited to 1:1 and may be adjusted as appropriate.

[0018] As shown in Figure 2, at least a portion of the first image light L1 emitted from the first display panel 10 passes through the optical mirror 30 and enters the user's pupil. Similarly, at least a portion of the second image light L2 emitted from the second display panel 20 is reflected by the optical mirror 30 and enters the user's pupil. This allows the user to view the images displayed on the first display panel 10 and the second display panel 20.

[0019] [Eyepiece 40] The eyepiece 40 is a convex lens positioned in front of the right eye and left eye of the user wearing the HMD 1. The eyepiece 40 refracts the incident first image light L1 and second image light L2 and directs them onto the user's retina. The eyepiece 40 has the function of magnifying the images displayed on the first display panel 10 and the second display panel 20 so that the user can see them. The eyepiece 40 may be composed of two or more lenses. The eyepiece 40 may also be a Fresnel lens or a liquid crystal lens.

[0020] [Display Image and Display Area] Figure 3 shows an example of a display image and display area in this embodiment. A user wearing the HMD1 views the display image D1 displayed on the first display panel 10 and the display image D2 displayed on the second display panel 20 in the display area A. The display area A is an area that includes display area A1 and display area A2 located inside the outer edge of display area A1. It is preferable that display area A1 is wider than display area A2.

[0021] The displayed image D2 should have a higher resolution than the displayed image D1. As shown in Figure 3, by placing the display area A2, where the high-resolution image is displayed, in an area with high human visual sensitivity, the user will be able to see a high-quality image.

[0022] [Display Method] The display method in this embodiment will be described with reference to Figures 4A to 4B. Figures 4A to 4D are diagrams illustrating an example of the display method in this embodiment.

[0023] In this embodiment, an example of image display using a rolling light emission method will be described. That is, display panel 10 and display panel 20 sequentially emit light from each pixel.

[0024] Figures 4A to 4D schematically show an example of display when it takes 4 ms to display one image. That is, it shows an example where one-quarter of the display area is displayed every 1 ms. Also, in Figures 4A to 4D, the direction from top to bottom is the main scanning direction, and the direction from right to left is the sub-scanning direction, and the pixels are illuminated sequentially. Note that the scanning direction and illumination start position are determined by the design of the display panel and are not limited to the examples shown.

[0025] Figure 4A shows the state 1 ms after the start of display. In display area A1, the display is performed in one-quarter of the area of ​​display area A1. Similarly, in display area A2, the display is performed in one-quarter of the area of ​​display area A2.

[0026] Figure 4B shows the state 2 ms after the start of display. In display area A1, the display is performed in half of the area of ​​display area A1. Similarly, in display area A2, the display is performed in half of the area of ​​display area A2.

[0027] Figure 4C shows the state 3 ms after the start of display. In display area A1, the display is performed in three-quarters of the entire area of ​​display area A1. Similarly, in display area A2, the display is performed in three-quarters of the entire area of ​​display area A2.

[0028] Figure 4D shows the state 4 ms after the start of display, when the display of one image has been completed.

[0029] In the display method of this embodiment, there is a delay between the timing of the display in display area A2 and the timing of the display in the area of ​​display area A1 that overlaps with display area A2. Specifically, 2 ms after the start of display, the right half of display area A2 is being displayed, but the area of ​​display area A1 that overlaps with that right half is not yet being displayed.

[0030] Furthermore, while Figures 4A to 4D illustrate an example where the display start timing is the same for display area A1 and display area A2, in configurations where the first display panel 10 and the second display panel are not synchronized, the display start timings themselves may differ. Thus, in this embodiment, the combination of the rolling light emission method and asynchronous operation results in different display timings for display area A1 and display area A2.

[0031] [Correction Process in This Embodiment] The correction process in this embodiment will be described with reference to Figures 5A and 5B. Figure 5A is a diagram illustrating the correction process in this embodiment when the head of the user wearing the HMD is stationary. Figure 5B is a diagram illustrating the correction process in this embodiment when the head of the user wearing the HMD moves at a speed greater than a predetermined speed. In addition, Figures 5A and 5B show the brightness of the display image D1 (dotted line) and the brightness of the display image D2 (solid line) on the B-B' line (see Figure 3) which includes the edge E of the display area A2.

[0032] The area in which the superimposed image D12, formed by the superposition of display image D1 and display image D2, is visible is defined as the correction target area a. The correction target area a is the area in which both the first display area D1 and the second display area D2 are displayed. In other words, the correction target area a is the area in which the brightness of both display image D1 and display image D2 is greater than 0.

[0033] As described above, the pixel illumination timing differs between the first display panel 10 and the second display panel 20. Therefore, if the user's head moves while the pixels on the second display panel 20, which has an earlier illumination timing, are emitting light, the pixels on the first display panel 10, which has a later illumination timing, will illuminate according to the new viewpoint after the head movement. As a result, an inconsistency occurs between the displayed image D1 and the displayed image D2, and a discontinuous image is visible at the boundary between the displayed image D1 and the displayed image D2.

[0034] Therefore, in this embodiment, a correction process is performed in the correction target area a, in which the brightness of the displayed image D2 is reduced and the brightness of the displayed image D1 is increased as it approaches the edge E. This correction process is a so-called blending process. By performing this correction process, the boundaries of the images can be made less noticeable. In the example shown in Figure 5A, the ratio of the brightness of the displayed image D1 to the brightness of the displayed image D2 is 1:1 at the center in the left-right direction of the correction target area a. Also, the ratio of the displayed image D2 is higher to the left of the center of the correction target area a, and the ratio of the displayed image D1 is higher to the right of the center.

[0035] Furthermore, in this embodiment, a configuration is adopted in which the correction process is dynamically changed according to the user's head movements. Specifically, as shown in Figure 5B, if the movement value related to the user's head movements is greater than or equal to a predetermined threshold, the width of the correction target area a is widened.

[0036] By widening the width of the correction target area a, the brightness of display image D1 and display image D2 in the correction target area a will change more smoothly towards the edge E. This makes it difficult to perceive any inconsistency between display image D1 and display image D2. As a result, it is possible to suppress the user from feeling uncomfortable. If the motion value related to the user's head movement falls below a predetermined threshold, the width of the correction target area a should be returned to the width shown in Figure 5A from the width shown in Figure 5B.

[0037] Here, the movement of the user's head was used as an example to explain the cause of image inconsistency in the correction target area a, but this is not the only example. For example, if the speed of the display object, at least in part, displayed in the superimposed image D12, is greater than a predetermined speed, the width of the correction target area a may be widened. This is because when the display object moves at high speed, discontinuous images may be visible at the boundary between display image D1 and display image D2.

[0038] Furthermore, in the correction target area a, it is preferable to change not only the brightness but also the resolution. Figure 6A shows the resolution of the second display image when the head of the user wearing the HMD is stationary in this embodiment. Figure 6B shows the resolution of the second display image when the head of the user wearing the HMD moves at a predetermined speed or faster in this embodiment. As mentioned above, display image D2 is an image with a higher resolution than display image D1.

[0039] As shown in Figure 6A, in the correction target area a, the resolution of the displayed image D2 is reduced as it approaches the edge E. That is, the resolution of the displayed image D2 is brought closer to the resolution of the displayed image D1 as it approaches the edge E. As a result, the displayed image D2 becomes less clearly visible in the correction target area a. Consequently, even if image inconsistencies occur, they can be made less noticeable.

[0040] Furthermore, if the motion value related to the user's head movement exceeds a predetermined threshold, the width of the correction target area a is widened, as shown in Figure 6B, to smooth the change in the resolution of the displayed image D2. This makes it less noticeable even if image inconsistencies occur.

[0041] The offset region b shown in Figures 5A to 6B is a region that defines the correction target region a, where the correction process is performed. The width of the offset region b may be fixed or even zero.

[0042] [Hardware Configuration of Display Correction System S] Figure 7 is a block diagram showing the hardware configuration of the display correction system according to this embodiment. As shown in Figure 7, the display correction system S may include, in addition to the first display panel 10 and the second display panel 20, a control unit 101, a storage unit 102, a communication unit 103, an operation unit 104, an IMU (Inertial Measurement Unit) 105, and an imaging device 106.

[0043] The control unit 101 includes at least one processor. The control unit 101 may be a program control device such as a CPU that operates according to a program installed in the display correction system S. Also, the control unit 101 may include a GPU (Graphics Processing Unit) that draws an image on the frame buffer based on graphics commands and data supplied from the CPU.

[0044] The storage unit 102 may include a main storage device such as a ROM or RAM and an auxiliary storage device such as an HDD or SSD. Programs executed by the control unit 101 and the like may be stored in the storage unit 102. In addition to programs for realizing various functions of the display correction system S described later, the storage unit 102 may store, for example, a game program (game software). Also, an area of the frame buffer on which an image is drawn by the GPU may be secured in the storage unit 102.

[0045] The communication unit 103 may be a communication interface such as an Ethernet (registered trademark) module or a wireless LAN module. The operation unit 104 is a user interface such as a controller, and may receive a user's operation input and output a signal indicating the content thereof to the control unit 101.

[0046] The IMU 105 may be a sensor that detects the movement of the head of a user wearing the HMD1. The IMU 105 may be able to detect, for example, the orientation, movement amount, speed, acceleration, etc. of the user's head.

[0047] The imaging device 106 may be a gaze camera that tracks the movement of the eyes of a user wearing the HMD1. Also, the HMD1 may have an imaging device such as a tracking camera that images the surrounding environment of a user wearing the HMD1.

[0048] [Functions Implemented by the Display Correction System S] FIG. 8 is a block diagram showing an example of functions implemented by the display correction system according to this embodiment. As shown in FIG. 8, in the display correction system S, a display control unit 201, a motion value acquisition unit 202, an object information acquisition unit 203, and a gaze information acquisition unit 204 may be implemented. These functions may be mainly implemented by the control unit 101 included in the HMD 1. However, it is not limited to this, and part or all of these functions may be implemented by a control unit included in a computer other than the HMD 1. That is, the display correction system S may be composed of a plurality of computers, not just the HMD 1. In this case, the plurality of computers may be wirelessly or wiredly connected to each other.

[0049] The display control unit 201 may control the displays of the first display panel 10 and the second display panel 20. The display control unit 201 may include a correction processing unit 201a. The correction processing unit 201a may change the luminance of the display image D1 and the luminance of the display image D2 as it goes from the display image D2 side to the display image D1 side in the correction target area a where the superimposed image D12 is visually recognized.

[0050] The motion value acquisition unit 202 may acquire motion values related to the movement of the user's head detected (sampled) by the IMU 105.

[0051] The object information acquisition unit 203 may acquire the speed of the display object at least part of which is displayed in the superimposed image D12. The speed of the display object may be acquired based on position information, motion vectors, depth information, etc.

[0052] Further, when the motion value acquired by the motion value acquisition unit 202 is greater than or equal to a predetermined threshold, the correction processing unit 201a may widen the width of the correction target area a. In this embodiment, the motion value is not limited to the speed of the user's head, and may be a value including the amount of change in the position of the user's head. That is, the change in the correction processing by the correction processing unit 201a may be performed when the speed of the user's head wearing the HMD 1 is greater than or equal to a predetermined speed and the amount of change is greater than or equal to a predetermined value. This is because image inconsistency is more likely to occur when the amount of change in the user's head is large.

[0053] Furthermore, if the speed of the display object acquired by the object information acquisition unit 203 is greater than or equal to a predetermined speed, the correction processing unit 201a may widen the width of the correction target area a.

[0054] The width of the correction target area a may be gradually widened according to the speed of the head movement of the user wearing the HMD1. For example, the correction processing unit 201a may widen the width of the correction target area a to the first width when the movement value is greater than or equal to the first threshold, and widen the width of the correction target area a to the second width which is wider than the first width when the movement value is greater than or equal to the second threshold which is greater than the first threshold.

[0055] Similarly, the width of the correction target area a may be gradually widened according to the speed of the display object displayed in the superimposed image D12. For example, the correction processing unit 201a may widen the width of the correction target area a to a first width when the speed of the display object is a first speed or higher, and widen the width of the correction target area a to a second width which is wider than the first width when the speed of the display object is a second speed or higher which is faster than the first speed.

[0056] The gaze information acquisition unit 204 may acquire information about the user's gaze detected by the gaze camera, which is the imaging device 106. The information about the user's gaze may include the direction and amount of change of the user's gaze. The display control unit 201 may then determine whether or not to change the correction process based on the information about the user's gaze. For example, even if the speed of the user's head, which is wearing the HMD1, is greater than a predetermined speed, if the user's gaze is directed towards the display area A and the amount of change of the gaze is small, the correction process may not be changed. Alternatively, even if the correction process is changed, the width of the correction target area a may be suppressed. This is because, while the user is gazing at the display area A, it is preferable to increase the brightness of the display image D2 to make the high-definition image easier to see.

[0057] [Modified Version] Next, with reference to Figure 9, the correction process in a modified version of this embodiment will be described. Figure 9 is a diagram illustrating the correction process in a modified version when the head of the user wearing the HMD moves at a predetermined speed or higher. Note that the same reference numerals are used for components and parts that have the same function as in this embodiment, and their descriptions are omitted.

[0058] As shown in Figure 9, in the modified example, if an image inconsistency occurs in the correction target area a, the brightness of the entire displayed image D2 is reduced, and the brightness of the area of ​​displayed image D1 that overlaps with displayed image D2 is increased. Furthermore, in the vicinity of the edge E of the correction target area a, a correction process is performed in which the brightness of displayed image D2 is reduced as it approaches the edge E, while the brightness of displayed image D1 is increased.

[0059] In the modified correction process, the luminance ratio of the displayed image D2 in the correction target area a is further reduced. As a result, the image resolution in the correction target area a is reduced, making it more difficult to perceive image inconsistencies.

[0060] [Other] The correction processing described in this embodiment and its modifications is merely an example and is not limited thereto. The correction processing unit 201a should change the ratio of the visibility-related elements of display image D1 to the visibility-related elements of display image D2 as you move from the display image D2 side to the display image D1 side in the correction target area a. Alternatively, the correction processing unit 201a should gradually change the ratio of the visibility-related elements of display image D1 to the visibility-related elements of display image D2 based on information regarding the cause of image inconsistency in the correction target area a. However, it is not limited to this, and at a minimum, the correction processing unit 201a should change the degree of change in the ratio of the visibility-related elements of display image D1 to the visibility-related elements of display image D2 depending on whether or not a cause of image inconsistency in the correction target area a occurs.

[0061] Furthermore, in this embodiment and its modified examples, an example was described in which the display image D2 has a higher resolution than the display image D1, and the ratio of the brightness of the display image D2 in the correction target area a is lowered, but the embodiment is not limited to this. That is, the resolution of the display image D2 and the resolution of the display image D1 may be the same. Even in that case, by making changes such as widening the width of the correction target area a, the inconsistency of the image can be made less perceptible.

[0062] Furthermore, while Figures 5A and 5B describe the correction process in the peripheral region of the right edge E of the displayed image D2, it is preferable to perform the same correction process on any of the top, bottom, left, or right edges of the displayed image D2.

[0063] Furthermore, although this embodiment has described an HMD1 having two display panels as an example, the number of display panels is not limited to this. For example, the HMD1 may further have a display panel that is positioned adjacent to the display panel 10 and displays a display image that is visible adjacent to the display image D1.
