Description

  Embodiments described herein relate generally to a stereoscopic image processing apparatus and a processing method.

  In general, in a stereoscopic image display method for displaying a stereoscopic image, a stereoscopic image is produced so that the viewer is at a preset position with respect to the display surface. For this reason, when the set position is different from the actual position of the viewer, there is a problem that the size and depth of the stereoscopic image are not displayed correctly.

JP 2006-333400 A

  Here, for example, if the amount of parallax is changed in accordance with the viewer's actual position and the size and depth of the stereoscopic image are displayed correctly, the changed parallax can be obtained when the viewer views the stereoscopic image at a distance close to the display surface. There is a risk that the amount becomes large, and there is a contradiction between convergence, which is a perceptual factor of stereoscopic images, and eye adjustment, and visual fatigue is likely to occur.

  The problem to be solved by the present invention is to provide a stereoscopic image processing apparatus and a processing method that can suppress visual fatigue in a viewer.

  The stereoscopic image signal processing device according to the present embodiment is an image processing unit that processes an input image, and when the viewing distance, which is the distance between the display screen of the display device and the viewer, exceeds a predetermined distance, A first parallax image of a first parallax amount corresponding to the input image is output to the display device, and the first parallax image corresponding to the input image when the viewing distance is within the predetermined distance; An image processing unit that outputs a second parallax image having a second parallax amount different from the one parallax amount to the display device is provided.

The block diagram which shows the image signal process part which concerns on 2nd Embodiment.

  Embodiments will be described below with reference to the drawings.

(First embodiment)
First, before describing the first embodiment, the viewer's interocular distance De, the distance (viewing distance) L between the viewer and the display surface, the parallax amount Pa, and the display are visually recognized by the viewer. The relationship of the distance (depth amount) z from the display surface to the object in the stereoscopic image will be described with reference to FIGS. 1 (a) and 1 (b). FIG. 1A is a diagram illustrating a case where the object A is displayed behind the display surface 10 a when viewed from the viewer 100, and FIG. 1B is a display surface when the object A is viewed from the viewer 100. It is a figure which shows the case where it displays before 10a. Point B indicates the left eye of the viewer 100, and point C indicates the right eye of the viewer 100. D is a point where a straight line connecting the object A and the left eye B of the viewer 100 intersects the display surface 10a, and E is a point where a straight line connecting the object A and the right eye C of the viewer 100 intersects the display surface 10a. Then, the length of the straight line DE becomes the parallax amount Pa.

Since the triangle ABC and the triangle ADE are similar, the parallax amount Pa in the case shown in FIG. 1A is obtained by the following equation (1).

Further, the parallax amount Pa in the case shown in FIG. 1B is obtained by the following equation (2).

  Here, as shown in FIG. 1A, the depth amount z when the object A is on the back side of the display surface 10a is a positive value, and the object A is displayed on the display surface as shown in FIG. The sign is determined so that the depth amount z in the case of 10a is a negative value. Note that the depth amount in the case illustrated in FIG. 1B is also referred to as a pop-out amount. In addition, when the line segment DE goes from top to bottom on the drawing as shown in FIG. 1A, the parallax amount Pa is set to a positive value, and the line segment DE is shown on the drawing as shown in FIG. When the sign is determined so that the parallax amount Pa becomes a negative value from the bottom to the top, the parallax amount Pa is expressed by the equation (1). That is, the formulas (1) and (2) are the same formula.

  As can be seen from the above formulas (1) and (2), when the depth amount z is constant, the parallax amount Pa increases as the viewing distance L decreases. It can also be seen that the depth amount z is proportional to the viewing distance L when the parallax amount Pa is constant.

  Next, the stereoscopic image signal processing apparatus of the first embodiment is shown in FIG. A stereoscopic image signal processing apparatus 1 according to this embodiment is a signal processing apparatus that processes a 2-parallax image signal including a parallax image for a left eye and a parallax image for a right eye, and is a glasses-type stereoscopic image display apparatus or The present invention can be used for a naked-eye type stereoscopic image display device. The stereoscopic image signal processing apparatus according to this embodiment includes a depth amount generation unit 2, an image signal processing unit 4, a viewing distance detection unit 6, a drive unit 8, and a display unit 10 having a display surface 10a. .

Amount of depth generation unit 2 analyzes the 2 parallax image signal input from the outside, generates or calculates the parallax amount Pa1 and set amount of depth z i of 2 parallax image input. The generation of the parallax amount Pa1 is performed using a known method. For example, the signal is separated into a background region and an image signal of the other region, a representative motion vector of the background region is calculated from the image motion vector and the motion vector of the background region, and the representative motion is calculated from the motion vector of the image. A relative motion vector is calculated by subtracting the vector, and a parallax amount Pa1 of the image signal is generated using the relative motion vector. In addition, when the parallax amount and the depth amount are included in the two-parallax image signal input from the outside, it is not necessary to generate the parallax amount and the depth amount of the image. The set depth amount z i is, for example, a position separated from the display surface 10a by a distance of three times the size H in the height direction of the display surface 10a when a parallax image with the parallax amount Pa1 is displayed on the display surface 10a. The depth amount of the stereoscopic image perceived by the viewer who views the video. That is, the depth amount generation unit 2 calculates the set depth amount z i by applying, for example, a preset mathematical formula to the parallax amount Pa1. The reason why the distance of three times the vertical size H of the display screen is used as the reference for the set depth amount z i is that, for example, the distance is recommended as the design viewing distance of the high-definition television. The viewing distance used to calculate the depth amount z i is not necessarily limited to this.

In addition, an image signal for two-dimensional display without parallax may be input to the depth amount generation unit 2. Also in this case, the depth amount generation unit 2 analyzes the input image signal and calculates a parallax amount Pa1 and a set depth amount z i for three-dimensional display. That is, the depth amount generation unit 2 analyzes the image signal for each frame, and uses relative movement of each pixel included in each frame by using, for example, a pixel movement between frames or a difference in pixel values within the same frame. Estimate or calculate depth position. Then, the depth amount generation unit 2 calculates a set depth position z i of each pixel based on the calculated relative depth position. The depth amount generation unit 2 generates or calculates a set depth amount z i for each of the images displayed on the screen.

  The viewing distance detection unit 6 detects a distance (viewing distance) L between the display surface 10a of the display unit 10 and the viewer, and may be a camera provided in the display unit 10, for example. In addition, it may be a detection device that is provided in the display unit 10 and transmits ultrasonic waves or infrared rays to detect a reflected wave from the viewer. That is, the viewing distance detection unit 6 may be any module that can detect at least the distance between the viewer and the display surface 10a. For example, the viewer and the stereoscopic image signal processing input from a module outside the stereoscopic image signal processing apparatus 1 may be used. The module which detects a distance using the information regarding the distance with the display surface 10a of the apparatus 1 may be sufficient. The viewing distance may be input from the outside. In this case, in the stereoscopic image signal processing device 1, the viewing distance detection unit 6 is not necessary.

The image signal processing unit 4 will be described with reference to FIGS. The configuration of the image signal processing unit 4 is shown in FIG. 3, and its operation is shown in FIG. As shown in FIG. 3, the image signal processing unit 4 includes a determination unit 41, a parallax amount setting unit 43, and an image signal correction unit 45. Determining unit 41, viewing distance L is determined whether a predetermined viewing distance L 1 is less than (step S1 in FIG. 4), and sends the determination result to the parallax amount setting unit 43.

As shown in FIG. 7, the predetermined viewing distance L 1 is when the stereoscopic image signal processing apparatus 1 displays a parallax image so that the viewer can view a stereoscopic image with the set depth amount z i. The depth amount z i perceived by the viewer and the depth of field z 0 of the naked eye coincide with each other. Each set depth amount z i is set for an image displayed on the screen. Therefore, the determination unit 41, for example, the absolute value of the set amount of depth z i for each of the image in one screen | z i | maximum value | z i | max is consistent with the depth of field z 0 gross distance may be used as the predetermined viewing distance L 1.

Further, as shown in FIG. 5, the set value z 0 is a function of the viewing distance L, and the viewer is at the viewing distance L and is focused on the display surface 10a. Alternatively, it represents the depth of field in the depth direction, and if the set value z 0 falls within the depth of field, contradiction between convergence and adjustment is unlikely to occur, and a fatigue reduction effect can be obtained. For example, Reference 1 (WN Charman, H. Whitefoot, “Pupil diameter and the depth of field of the human eye as measured by laser speckle,” Optica Acta, pp. 1211-1216, Vol. 24 (1977))) and references 2 (S. Marcos, E. Moreno, R. Navarro, The depth-of-field of the human eye from objective and subjective measurements, “Vision Res., Pp. 2039-2049, Vol. 39 (1999)). Thus, it is known that the depth of field of the naked eye is ± 0.2D to 0.3D, where D is a unit of refractive index of a lens having diopters and a reciprocal dimension of distance. For example, assuming that ± 0.2D, the viewing distance is L, and the set value is z 0 , the depth of field can be expressed by equation (3).

That is, the set value z 0 is expressed by the equation (4).

The parallax amount setting unit 43 sets the parallax amount Pa of the image displayed on the display unit 10 based on the determination result of the determination unit 41. Absolute value of the set amount of depth z i of the image displayed on the screen | z i | maximum value | z i | if max exceeds the set value z 0, i.e. viewing distance L is than the predetermined viewing distance L 1 If it is smaller (Yes in step S1), the set depth amount z i is multiplied by z 0 / | z i | max so that | z i | max does not exceed z 0 , z i × z The parallax amount Pa obtained by substituting 0 / | z i | max into L and z in the above equation (1) is set as z (steps S2 and S4 in FIG. 4).

When the maximum absolute value of the set depth amount z i is equal to or smaller than the set value z 0 , that is, when L is greater than L 1 (No in step S1), the viewer can view a stereoscopic image of the set depth amount z i. In order to be able to perceive, the parallax calculation distance is set as the measurement visual distance L, and the parallax amount Pa obtained by substituting the measurement visual distance L and the set depth amount z i into L and z in the above equation (1) is set. (Steps S3 and S4 in FIG. 4). In this case, the depth amount z is given a positive or negative sign. When the set parallax amount Pa is displayed in a graph, it is as shown in FIG. That is, the parallax amount Pa that is set, when the viewing distance L is equal to or less than a predetermined viewing distance L 1, as shown in the graph g 1, (1) formula z = z i × z 0 / | z i | The value changes as a value obtained by substituting max and L = L, and when it is larger than the predetermined viewing distance L 1 , the value obtained by substituting z = z i and L = L into the equation (1) as shown in the graph g 2. Therefore, it changes and is set so that the parallax amount matches the depth amount and viewing distance of the input two-parallax image signal. Here, the predetermined viewing distance L 1 is set as the interocular distance De at a set viewing distance L 0 (for example, as shown in FIG. 2, when the height of the display surface 10a is H, L 0 = 3H). When the depth amount z i is calculated, the absolute value with the larger absolute value of the maximum value z i max and the minimum value z i min of the set depth amount z i of each image displayed on the screen is the set value z. 5 and the value indicated by the graph g 1 in FIG. 5 means a parallax amount where the maximum value of the depth amount of the image in the screen when the viewer is located is the set value z 0. To do.

Note that the parallax amount Pa in FIG. 5 indicates, for example, the parallax amount of the same image that is continuously displayed in at least a part of the frames that are continuously displayed in time. For this reason, when images with different parallax amounts are displayed on the same screen (when a three-dimensional image with unevenness is displayed), these images are displayed while maintaining a proportional relationship of the parallax amount for each image. Is done. That is, when a parallax image is displayed on the display screen, the parallax amount (depth amount) may differ depending on the position (image) of the screen. In this case, the stereoscopic image signal processing apparatus 1 calculates a set depth amount z i for each position (image), and adjusts the parallax using the distance L and Equation (1). The distance between the viewer and the display screen in the case of L 1 or less, the parallax amount of the image corresponding to the parallax amount when substituting L 1 to L of the formula (1) for calculating the parallax amount. The set parallax amount has a characteristic having a bending point at the set viewing distance L 0 , but the graph g 1 and the graph g 2 are smoothly connected as in the graph g 3 shown in FIG. You may make it have a characteristic. Further, here, it has been described that the maximum value of the depth amount of the image displayed in the display screen is matched with the set value z 0 , but for example, an area (number of pixels, etc.) of a certain ratio in the image displayed in the display screen. ) amount of depth of image occupying, the depth of a predetermined frequency based on a histogram of the amount of depth can also be adjusted to the set value z 0.

  The parallax amount set by the parallax amount setting unit 43 in this way is sent to the image signal correction unit 45 (see FIG. 3), and the image signal is corrected based on the set parallax amount. The image signal corrected by the image signal correction unit 45 is output to the display unit 10 via the drive unit 8, and a stereoscopic image is displayed (see FIG. 2).

  As described above, according to the first embodiment, when the depth amount of the input two-parallax image exceeds the depth of field at the viewing distance, the depth of field at the ideal viewing distance is set. Since the parallax amount of the two-parallax image signal is set, the contradiction between the convergence and the eye adjustment function can be suppressed, and the visual fatigue of the viewer can be suppressed. In addition, when the depth amount of the input two-parallax image is within the depth of field at the viewing distance, the parallax amount is set so as to match the depth amount. It is possible to view a high-quality stereoscopic image that does not occur and is not distorted.

  The above embodiment will be described in other words. It is assumed that the stereoscopic image signal processing apparatus 1 displays an image with a parallax amount Pax, for example, and the viewer perceives a stereoscopic image with a depth amount (jump amount, sinking amount) x. Here, for example, when the viewer approaches the stereoscopic image signal processing device 1 and the stereoscopic image signal processing device 1 detects a change in the distance L between the viewer and its own device, the stereoscopic image signal processing device 1 And an image in which the parallax amount is adjusted so that the viewer can continuously perceive the stereoscopic image having the depth amount x based on the equation (1) and (1). Then, when the viewer comes closer to the predetermined distance, the stereoscopic image signal processing apparatus 1 causes the parallax amount to decrease with the reduction of the viewing distance L so that the depth amount falls within the depth of field, thereby reducing the depth amount. Restrict.

  That is, the stereoscopic image signal processing apparatus 1 changes the distance between the viewer and the display screen when the viewer displays a parallax image corresponding to the input image that is separated from the display screen by a predetermined distance. When the changed viewing distance is longer than the predetermined distance, a parallax image corresponding to the input image and having a parallax amount corresponding to the viewing distance according to the equation (1) is displayed. . The viewer recognizes a stereoscopic image of the image displayed at the same depth position before and after the distance from the display screen changes. However, when the viewer comes to a position within a predetermined distance from the display screen, the viewing distance L and the subject's naked eye coverage are set so that the depth position of the stereoscopic image perceived by the viewer is within the viewer's depth of field. A parallax image having a parallax amount corresponding to the depth of field is displayed.

(Second Embodiment)
A stereoscopic image signal processing apparatus according to the second embodiment is shown in FIG. The stereoscopic image signal processing apparatus 1A of the second embodiment has a configuration in which the image signal processing unit 4 is replaced with an image signal processing unit 4A in the stereoscopic image signal processing apparatus 1 of the first embodiment shown in FIG. . As shown in FIG. 9, the image signal processing unit 4A includes a determination unit 41A, a blur processing unit 42, a parallax amount setting unit 43A, and an image signal correction unit 45A.

Determination unit 41A includes a set amount of depth z i of the image, based on the viewing distance L, the absolute value of the set amount of depth z i | z i | maximum value | z i | max is below the set value z 0 determines whether the absolute value of the amount of depth z | z i | maximum value of | z i | max is the region of the set value z 0 or less is the image, the command signal is the parallax amount setting unit 43A The parallax amount is set and the command signal is sent to the blur processing unit 42 for the image area exceeding the set value z 0 to perform the blur processing.

The blur processing unit 42 performs blur processing on an image of a portion where the depth of field of the image region where the set depth amount z i of the image exceeds the set value z 0 is exceeded. A known technique, for example, a smoothing filter is used for this blurring process.

Parallax amount setting unit 43A, the absolute value of the image each set amount of depth z i that is displayed on the screen | z i | maximum value | z i | max is, for a region of the set value z 0 or less is the image In the same manner as described in the first embodiment, the parallax calculation distance L ′ is set as the measurement viewing distance L so that the viewer can perceive a stereoscopic image having the set depth amount z i , and the measurement viewing distance L and the set depth are set. A parallax amount Pa obtained by substituting the amount z i into L and z in the above equation (1) is set (steps S3 and S4 in FIG. 4). In this case, the depth amount z i is given a positive or negative sign. That is, when the viewing distance L is equal to or less than the predetermined viewing distance L 1 , the set parallax amount Pa is expressed by z = z i × z 0 / | z | max as shown in the graph g 1. And L = L, and changes as a value substituted by L = L. If the distance is larger than the predetermined viewing distance L 1, the value changes according to the value obtained by substituting Z = Zi and L = L in equation (1) as shown in graph g 2. Then, the parallax amount is set so as to match the depth amount and viewing distance of the input two-parallax image signal. Further, when the maximum value | z i | max of the absolute value | z i | of the set depth amount z i exceeds the set value z 0 , the image signal in which the blur processing is performed by the blur processing unit 42, the absolute value of the amount of depth z i | z i | z i | | maximum value with respect to the max set value z 0 following areas, is corrected so that the parallax amount set by the disparity amount setting unit 43A.

  The image signal correction unit 45 </ b> A corrects the image signal using the parallax amount set by the parallax amount setting unit 43 </ b> A and sends the corrected image signal to the driving unit 8.

As described above, in the second embodiment, when the depth amount of the input two-parallax image exceeds the depth of field at the viewing distance, the image of the portion exceeding the depth of field is used. Since the blur processing is performed and the area of the value z 0 or less is set to have the parallax amount suitable for the depth amount and the viewing distance, the contradiction between the convergence and the eye adjustment function is suppressed. This makes it possible to suppress visual fatigue on the viewer and to view a high-quality stereoscopic image that is not distorted. Further, when the depth amount of the input two-parallax image is within the depth of field at the viewing distance, the parallax amount matches the depth amount and the viewing distance as described in the first embodiment. Thus, it is possible to view a high-quality stereoscopic image that does not cause visual fatigue and does not distort the viewer.

  Note that the stereoscopic image signal processing apparatus according to the first and second embodiments includes the visual distance detection unit 6, the drive unit 8, and the display unit 10, but a video recording / reproducing apparatus that does not include these devices, for example, It can be used for DVD players and the like. In this case, the viewing distance information needs to be input from the outside.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
