Hereinafter, embodiments according to the present technology will be described with reference to the drawings.
A of
The luminance meter 1 detects a luminance of a right-eye image or a left-eye image emitted from the auto-stereoscopic display 10. In the present embodiment, the movement apparatus 3 supports the luminance meter 1 and the luminance meter 1 also moves along with a movement of the movement apparatus 3. For example, a two-dimensional luminance meter capable of acquiring data on a luminance and the like in a two-dimensional manner may be used as the luminance meter 1, and a luminance value in a desired area may be acquired.
The object 2 is arranged to be sensed by the auto-stereoscopic display 10. For example, in A of FIG. 1, the object 2 is a picture representing a human face. In the present embodiment, the right eye and the left eye have holes 6 and the luminance meter 1 is installed in these positions. That is, the luminance meter 1 moves together with the object 2 and detects the luminance of the right-eye image or the left-eye image emitted from the auto-stereoscopic display 10 through the hole 6 for the right eye or through the hole 6 for the left eye.
It should be noted that the object used for sensing is not limited, and any object may be used in accordance with a sensing method. For example, a marker may be associated with the object 2 and the marker may be tracked. In this case, a hole is opened at the marker position and the luminance meter 1 detects the luminance through the hole.
The movement apparatus 3 includes a support bar 4 that supports the luminance meter 1 and a driving stage 5 that drives the support bar 4. In the present embodiment, the movement apparatus 3 drives the driving stage 5, thereby moving the support bar 4. Accordingly, it is possible to move the luminance meter 1 to reach a predetermined position and a predetermined velocity.
It should be noted that the shape of the movement apparatus 3 is not limited, and the movement apparatus 3 may include the driving stage 5 capable of being driven in a circular arc on the basis of the auto-stereoscopic display 10 or the movement apparatus 3 may be capable of being driven in any direction such as a front-rear direction or an oblique direction with respect to the auto-stereoscopic display 10. As a matter of course, the support bar 4 may be provided with a joint portion capable of changing the position of the luminance meter 1.
The auto-stereoscopic display 10 is a display apparatus capable of displaying a stereoscopic image (right-eye image and left-eye image). The auto-stereoscopic display 10 is capable of displaying a stereoscopic three-dimensional video by emitting different parallax images between the right eye and the left eye at respective different viewpoints.
In the present embodiment, the auto-stereoscopic display 10 includes a camera 11. The camera 11 is capable of tracking the object 2. For example, in A of
Moreover, in the present embodiment, the auto-stereoscopic display 10 emits white images, black images, or particular images including a predetermined pattern which are used checking crosstalk as the right-eye image and the left-eye image. Hereinafter, the white images, the black images, or the particular images including a predetermined pattern will be referred to as pattern images.
In the present embodiment, the particular images including a predetermined pattern are a right-eye image and a left-eye image different in luminance level. For example, in a case where the black image enters the right eye and the white image enters the left eye, the white image is mixed in the black image (or the black image is mixed in the white image) if crosstalk occurs. The crosstalk is evaluated based on a degree of such mixing.
It should be noted that the type of particular images including a predetermined pattern is not limited, and the right-eye image and the left-eye image different in a position of an object displayed in an image, a depth of the object, a shape of the object, or the like may be used.
The information processing apparatus 20 controls the movement apparatus 3 in accordance with a measurement point based on the auto-stereoscopic display 10. The measurement point is a position where crosstalk is assumed to occur. For example, for checking whether or not crosstalk occurs at a position in front of the auto-stereoscopic display 10, the position is a measurement point. Typically, the position where the crosstalk occurs depends on the design and the like of the auto-stereoscopic display 10.
In the present embodiment, a position (point) where crosstalk is assumed to occur or a region including the position is set as the measurement point.

As shown in B of
Moreover, the information processing apparatus 20 controls the exposure timing of the luminance meter 1 on the basis of movement information of the luminance meter 1 obtained from the movement apparatus 3. The movement information is information regarding a movement time of the luminance meter 1. For example, the movement information includes the position, the velocity, and the movement time of the luminance meter 1. In the present embodiment, when the luminance meter 1 reaches the predetermined position and the predetermined velocity, the information processing apparatus 20 outputs a trigger to start exposure to the luminance meter 1 (hereinafter, referred to as exposure ON trigger).
Moreover, the information processing apparatus 20 acquires luminance data in a case where the amount of exposure acquired by the luminance meter 1 has satisfied a predetermined condition, i.e., in a case where the amount of exposure has been sufficiently secured. In the present embodiment, the exposure duration is short with only one exposure performed while the luminance meter 1 is moving, so measurement is performed multiple times. That is, exposure is performed when the luminance meter 1 reaches the predetermined position and the predetermined velocity, and then exposure is performed when the luminance meter 1 returns to the original position (e.g., a position 13 of the luminance meter 1 in B of
C of
As shown in B and C of
As shown in C of
It should be noted that the exposure of the luminance meter 1 may be stopped by an exposure OFF trigger to stop exposure or may be set in advance to stop after several seconds elapse from the exposure ON trigger. It should be noted that although the start point 14 of the measurement point 12 is different from the position of the luminance meter 1 when the exposure ON trigger 18 is supplied in C of
Moreover, the information processing apparatus 20 evaluates crosstalk of the auto-stereoscopic display 10 on the basis of the luminance data acquired at at least one exposure timing. In the present embodiment, crosstalk while the luminance meter 1 is moving, i.e., dynamic crosstalk is converted into a numeric value on the basis of the luminance data.
It should be noted that the dynamic crosstalk refers to crosstalk generated for a time (motion to photon latency) for which the luminance meter 1 moves, the position of the luminance meter 1 is recognized, a stereoscopic image is drawn and generated and output to the display of the auto-stereoscopic display 10, and light is actually emitted.
The information processing apparatus 20 includes hardware required for a computer configuration, such as processors, e.g., a CPU, a GPU, and a DSP, memories, e.g., a ROM and a RAM, and a storage device, e.g., an HDD (see
For example, any computer such as a PC can realize the information processing apparatus 20. As a matter of course, hardware such as an FPGA and an ASIC may be used.
In the present embodiment, an evaluation unit as a functional block is configured by the CPU executing a predetermined program. As a matter of course, dedicated hardware such as an integrated circuit (IC) may be used in order to realize the functional blocks.
The program is installed into the information processing apparatus 20, for example, via various recording media. Alternatively, the program may be installed via the Internet or the like.
The type of recording medium on which the program is recorded and the like are not limited, and any computer-readable recording medium may be used. For example, any computer-readable non-transitory storage medium may be used.

The information acquisition unit 21 acquires various types of information. In the present embodiment, the information acquisition unit 21 acquires the luminance data from the luminance meter 1 and acquires the movement information of the luminance meter 1 from the movement apparatus 3. Moreover, the acquired movement information is supplied to the exposure control unit 24. The luminance data is supplied to the evaluation unit 26.
The measurement point setting unit 22 sets a measurement point. In the present embodiment, the measurement point setting unit 22 sets a start point and an end point of the measurement point. For example, the measurement point setting unit 22 sets the positions of the start point and the end point in accordance with a direction in which the movement apparatus 3 is capable of being driven. It should be noted that in a case where the measurement point is not a region, but only a single point, the same position (coordinates) may be set as the start point and the end point. Information about the set measurement point is supplied to the movement control unit 23 and the image control unit 25.
The movement control unit 23 controls the movement apparatus 3. In the present embodiment, the movement control unit 23 controls the driving stage 5 of the movement apparatus 3 on the basis of the set measurement point. For example, the movement control unit 23 outputs to the movement apparatus 3 a control signal for controlling the driving stage 5 so that the luminance meter 1 reaches the predetermined position and the predetermined velocity between the start point and the end point.
The exposure control unit 24 controls the exposure timing of the luminance meter 1. In the present embodiment, the exposure control unit 24 outputs the exposure ON trigger to the luminance meter 1 on the basis of the movement information of the luminance meter 1 supplied from the movement apparatus 3.
The image control unit 25 controls an image displayed on the auto-stereoscopic display 10. In the present embodiment, the image control unit 25 controls so that the pattern images are displayed on the display of the auto-stereoscopic display 10.
For example, as shown in A of
The evaluation unit 26 evaluates crosstalk of the auto-stereoscopic display 10. In the present embodiment, the evaluation unit 26 calculates a value of crosstalk on the basis of the luminance data in each region of the right-eye image or the left-eye image.
For example, as shown in B of
As a matter of course, the expression for determining crosstalk is not limited, and it may be calculated by any mathematical method. For example, in a case where an image other than the black image and the white image is used, any gradation of this image may be substituted into the expression and the value of crosstalk may be calculated.
It should be noted that in the present embodiment, the auto-stereoscopic display 10 corresponds to an image display apparatus that includes a sensor unit that tracks an object and emits the right-eye image or the left-eye image to the luminance meter.
It should be noted that in the present embodiment, the information acquisition unit 21 functions as a first acquisition unit that acquires movement information regarding a movement time of a luminance meter, the movement information including at least position information of the luminance meter, and a second acquisition unit that acquires, in a case where a sum of the respective amounts of exposure acquired at the at least one exposure timing has satisfied a predetermined condition, the sum of the respective amounts of exposure as luminance data.
It should be noted that in the present embodiment, the measurement point setting unit 22 corresponds to a setting unit that sets the measurement point.
It should be noted that in the present embodiment, the movement control unit 23 corresponds to a movement control unit that controls the movement apparatus in accordance with a measurement point based on the image display apparatus.
It should be noted that in the present embodiment, the exposure control unit 24 corresponds to an exposure control unit that controls an exposure timing of the luminance meter on the basis of the movement information.
It should be noted that in the present embodiment, the image control unit 25 corresponds to a display control unit that controls the right-eye image and the left-eye image emitted from the image display apparatus.
It should be noted that in the present embodiment, the evaluation unit 26 corresponds to an evaluation unit that evaluates crosstalk of the image display apparatus on the basis of the luminance data.
As shown in
The position and angle of the camera 11 that tracks the object associated with the luminance meter 1 are adjusted (Step 103). For example, the determination unit that determines whether or not the camera 11 is correctly tracking the object 2 may perform the adjustment or the user may be provided with a message, a graphical user interface (GUI), or the like for prompting the user to adjust the position and angle of the camera 11.
The movement control unit 23 sets the velocity of the luminance meter 1 (Step 104). In the present embodiment, crosstalk at each predetermined velocity of the luminance meter 1 is evaluated. For example, the movement control unit 23 is set so that the luminance meter 1 moves from the start point to the end point at 5 cm/s. Moreover, for example, in a case where measurement has been completed at a set velocity, measurement may be performed at a different velocity at the same measurement point.
That is, the measurement may be performed at a plurality of different velocities of the luminance meter 1 with respect to a single measurement point and crosstalk may be evaluated on the basis of luminance data at each of these velocities. As a matter of course, also with respect to a newly set measurement point, evaluation may be performed in a similar way.
The image control unit 25 displays the pattern images on the auto-stereoscopic display 10 (Step 105). From Step 105, the movement of the luminance meter 1 is started and the measurement of the luminance data is performed. In the present embodiment, by the movement control unit 23 controlling the driving stage 5, the luminance meter 1 moves between the start point and the end point of the measurement point set by the measurement point setting unit 22.
The information acquisition unit 21 acquires the movement information of the luminance meter 1 (Step 106). In the present embodiment, the information acquisition unit 21 acquires the position and velocity of the luminance meter 1.
The exposure control unit 24 performs exposure of the luminance meter 1 (Step 107). In the present embodiment, the exposure control unit 24 outputs the exposure ON trigger to the luminance meter 1 when the luminance meter 1 reaches the velocity set between the start point and the end point.
Whether or not measurement of all pattern images of the white images, the black images, and the particular images including a predetermined pattern displayed on the auto-stereoscopic display 10 has been completed is determined (Step 108). In the present embodiment, the measurement completion refers to that fact that luminance data when a sufficient amount of exposure has been successfully secured has been acquired. That is, when the white images are displayed on the auto-stereoscopic display 10, exposure of the luminance meter 1 is performed multiple times, a sufficient amount of exposure is secured, and luminance data is acquired, and then the measurement of a first pattern is completed.
In a case where the measurement of all pattern images has not been completed (NO in Step 108), the black images are displayed on the auto-stereoscopic display 10. From Step 106 and 107, when the black images are displayed, exposure of the luminance meter 1 is performed multiple times and luminance data is acquired, and then measurement of patterns of both eyes is completed. Also, when the particular images including a predetermined pattern are displayed, exposure of the luminance meter 1 is performed multiple times and luminance data is acquired, and then measurement of a third pattern is completed.
In a case where the measurement of all pattern images has been completed (YES in Step 108), the evaluation unit 26 calculates a value of crosstalk on the basis of the acquired luminance data.
In
Moreover, in a case where the movement apparatus is driven only in a predetermined direction (direction of the line 31), the movement control unit 23 may control the angle of the luminance meter 1 so that the luminance meter 1 constantly faces the measurement point 30. It should be noted that the angle of the luminance meter 1 does not need to be controlled depending on a distance (range) by which the luminance meter 1 moves.
The exposure control unit 24 outputs the exposure ON trigger when the luminance meter 1 reaches a predetermined position 32 and a predetermined velocity. It should be noted that the exposure control unit 24 may output the exposure ON trigger two times by reciprocation of an initial position 33 and a stop position 34. Moreover, luminance values acquired in respective measurements may be averaged as the acquired luminance data.
Accordingly, the accuracy of the luminance measurement can increase through simple repetition and averaging, and the same point can be measured.
As shown in
In the measurement system 110 shown in
The measurement point setting unit 22 sets the measurement point 41. The movement control unit 23 controls the mirror-moving apparatus on the basis of the set measurement point 41. For example, the movement control unit 23 controls the mirror-moving apparatus so that the mirror 40 reaches the predetermined position and the predetermined velocity.
Moreover, the exposure control unit 24 outputs the exposure ON trigger on the basis of the position, velocity, or movement time of the mirror 40.
Accordingly, the drive portion can be simplified and the size and costs of the measurement system can be reduced.
As shown in

Accordingly, lowering of the measurement accuracy due to stray light can be prevented and the measurement accuracy can increase.
Hereinabove, the measurement system 100 according to the present embodiment includes the luminance meter 1, the object 2, the auto-stereoscopic display 10 that includes the camera 11 that tracks the object 2 and emits the right-eye image or the left-eye image to the luminance meter 1, the movement apparatus 3, and the information processing apparatus 20. The information processing apparatus 20 controls the movement apparatus 3 in accordance with the measurement point 12 based on the auto-stereoscopic display 10, controls the exposure timing of the luminance meter 1 on the basis of the movement information regarding the movement time of the luminance meter 1, and acquires the sum of the respective amounts of exposure as the luminance data in a case where the sum of the respective amounts of exposure acquired at at least one exposure timing has satisfied a predetermined condition. Accordingly, a high-quality viewing experience can be realized.
Conventionally, in the display apparatus that enables a stereoscopic image such as an auto-stereoscopic display to be viewed, crosstalk occurs and affects the video quality and flat fusion for a 3D video. It is difficult to accurately measure such crosstalk with the luminance meter. In particular, in a case where the luminance meter moves, it is difficult to secure the accuracy at low luminance due to an insufficient exposure duration, and thus the measurement accuracy of the crosstalk.
In the present technology, measurement is performed multiple times on the basis of the position and velocity of the moving luminance meter. Accordingly, complementing the insufficiency of the exposure duration, the amount of exposure can be sufficiently secured, sufficient accuracy can be obtained for the luminance measurement, and a high-accuracy crosstalk measurement can be performed. Moreover, measurement can be performed only by aimed setting for performing exposure when the luminance meter reaches the predetermined position and the predetermined velocity, and the measurement accuracy can increase. Moreover, since the luminance meter moves in parallel with the measurement point, the configuration and installation of the measurement apparatus can be simplified.
The present technology is not limited to the above-mentioned embodiment, and various other embodiments can be realized.
In the above-mentioned embodiment, the exposure control unit 24 outputs the exposure ON trigger only when the luminance meter 1 is at the predetermined position and the predetermined velocity. The present technology is not limited thereto, and the timing to perform exposure may be arbitrarily set. For example, the exposure control unit 24 may stop the exposure of the luminance meter other than a desired time zone. Accordingly, it is possible to reduce the influence of dark current of the sensor and increase the accuracy.
In the above-mentioned embodiment, the luminance meter 1 moves to the measurement point multiple times and the luminance measurement is performed. The present technology is not limited thereto, and a luminance distribution of the measurement point may be measured in advance and the luminance data may be complemented.
In the above-mentioned embodiment, the auto-stereoscopic display 10 displays a stereoscopic image of the right-eye image and the left-eye image. The present technology is not limited thereto, and an eyeglasses-type display apparatus capable of displaying a stereoscopic image may be used. For example, the luminance meter may detect the luminance by measuring a stereoscopic vision display that alternately outputs the right-eye image and the left-eye image at predetermined time intervals through the eyeglasses-type display apparatus capable of alternately shielding a lens on the side of the right eye and a lens on the side of the left eye at predetermined time intervals.
In the above-mentioned embodiment, the position and velocity of the luminance meter 1 are acquired in Step 106. The present technology is not limited thereto, and only the position of the luminance meter 1 may be acquired and the exposure ON trigger may be output. For example, in a case where there is a sufficient distance between the position of the luminance meter 1 before it moves and a position where it reaches the velocity of the luminance meter 1 set in Step 104 with respect to the predetermined position, the exposure ON trigger may be output when the luminance meter 1 reaches the predetermined position.
In the above-mentioned embodiment, in Step 108, the three patterns of images, i.e., the black images, the white images, and the particular images including a predetermined pattern, are emitted from the auto-stereoscopic display 10. The present technology is not limited thereto, and any number of pattern images may be emitted. For example, in a case where the luminance data of the black images and the white images is measured in advance, the luminance data may be used. That is, in Step 108, it may be determined that measurement has been completed only by measurement of the particular images including a predetermined pattern.
In the above-mentioned embodiment, the luminance measurement at the single measurement point is performed. The present technology is not limited thereto, and the luminance measurement may be performed at a plurality of measurement points. For example, the luminance meter may pass through the plurality of measurement points and measure the luminance at each measurement point. In this case, the evaluation unit 26 may evaluate crosstalk at each measurement point on the basis of luminance data at each measurement point.
