DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. A detection line-of-sight position correction device A1 as the above-described line-of-sight detection device according to the present invention is configured as shown in FIG.
2, a shift detection unit 16, a correction unit 18, and a display unit 20.
And a display control unit 22. The computer terminal P shown in FIG. 2 is assumed to be equipped with the detection line-of-sight position correction device A1 having the above configuration.

Here, the camera 10 is for photographing a user's face in particular, and as shown in FIG.
Is installed so as to capture the face of the user in front of the user.
This camera 10 is constituted by a CCD camera or the like.
Further, the line-of-sight detection unit 12 as the line-of-sight detection means
Is for detecting a line of sight from image data obtained by the camera 10, and detects a line of sight of a person when the image data has a human face and faces the display unit 20. Specifically, edge extraction is performed on image data obtained by shooting, and when a human face is captured, the direction of the iris in the eyes is detected. Details will be described later. Further, the line-of-sight detection unit 12 is provided with a line-of-sight detection information storage unit 14. The gaze detection information storage unit 14 stores a gaze detection table used for gaze detection. That is, the line-of-sight detection table stores a plurality of pieces of position information of coordinate positions and corresponding density distribution information. In the data in the eye gaze detection information storage unit 14, data defaulted in advance for the initial eye gaze detection are also stored separately from the additional data taken in with the target display.

That is, the line-of-sight detection information storage unit 14
A table as shown in FIG. 3 is provided. For example,
As for the image data 1, the line-of-sight position (x1, y1) corresponding to the image data 1 is stored. It is assumed that each image data is separately extracted and stored as density distribution information in the X direction and density distribution information in the Y direction. For example, the image data 1 is stored separately for density distribution information in the X direction and density distribution information in the Y direction. The density distribution information is constituted by, for example, a histogram curve. In FIG. 3, image data 1 to image data n are default image data. That is, general image data is stored in advance. Further, the additional data in FIG. 3 is image data obtained when the correction target is displayed. This density distribution information functions as the detection data. Further, the line-of-sight detection information storage unit 14 functions as the storage unit.
The gaze detection unit 12 actually includes a memory that stores various data such as a program for performing gaze detection, and a CPU that performs predetermined processing according to the program.

The shift detecting section 16 detects a shift in the line of sight based on the detected position of the line of sight. For example, it is determined that there is a shift in the line-of-sight position when the detected line-of-sight position is frequently outside the display unit 20 or when the gazing point is biased toward a certain area. Further, the shift detecting unit 16
Is to compare the line-of-sight position detected by the line-of-sight detection unit 12 with the target position from the display control unit 22 to detect a shift between them. That is, the shift direction and the shift amount between the line-of-sight position and the target position are detected.
The details will be described later. The shift detector 16 functions as a shift detector and a second shift detector.

The correction unit 1 as the correction means
Numeral 8 is for correcting the detected line-of-sight position. Specifically, when a shift is detected, the image data at that time is fetched and stored in the line-of-sight detection information storage unit 14. When storing the image data in the eye-gaze detection information storage unit 14, it is made to correspond to the information on the target position.
As a result, the information of the image data is used in the subsequent gaze detection.

If there is already defaulted image data for the coordinates of the displayed target position, a process for averaging the image data and the image data obtained by displaying the correction target is performed. That is, the density distribution information as the pattern images in the X direction and the Y direction for the same coordinate position is averaged. The display section 20 as the display means is for displaying predetermined information, and is constituted by a monitor such as a CRT or an LCD.

The display control section 22 controls display on the display section 20. In particular, when a shift is detected by the shift detection section 16, a target for line-of-sight detection is displayed on the display section 20. Control. The target may be a display body having a size capable of detecting the line of sight, and may be a character such as a character or a symbol, or may be a figure or the like. The display control unit 22 functions as the display body display unit.

The operation of the detection line-of-sight position correcting apparatus A1 having the above configuration will be described with reference to FIG. First, it is assumed that the user is performing a process using the computer terminal P equipped with the detection line-of-sight position correction device A1 having the above configuration.
This processing is arbitrary, such as input of characters by a word processor, processing by spreadsheets, and the like.

First, image data is taken into the camera by 10 (S10). That is, the camera 10 photographs the face of the user A. Then, the image captured by the camera 10 is sent to the visual line detection unit 12. Next, the line-of-sight detection unit 12 performs line-of-sight detection (S11).
That is, first, the line-of-sight detection unit 12 performs an edge extraction process on the captured image. Then, after the edge extraction processing, first, it is detected whether or not there is a human face. In other words, the image subjected to the edge extraction processing is compared with the person standard pattern image to estimate whether or not there is a human face.
The determination of a human face may be performed in consideration of skin color information. The moving object may be detected from the difference image between the frames, and the human face may be determined by comparing the moving object with the person standard pattern image.

If it is detected that there is a human face, the line of sight is detected. Here, the gaze direction is detected. That is,
From the edge information obtained by extracting the edges, the vertical position and the horizontal position of the eyes in the detected human face are estimated to cut out an image of the eye portion, and a grayscale image of the cut out region Generate Thereafter, the density distribution information regarding the position of the iris in the eye is calculated for the horizontal direction and the vertical direction, and the density distribution information for the horizontal direction and the vertical direction is calculated in advance, and the similarity is calculated to detect the gaze direction. It is. The horizontal density distribution information and the vertical density distribution information from the image data 1 to the image data n in the table of FIG. 3 correspond to the previously provided horizontal and vertical density distribution information. Note that, when the density distribution information stored in the table is increased by displaying the correction target, these are also taken into consideration in gaze detection. At the beginning of the process, since there is no additional data shown in FIG. 3, the line-of-sight detection is performed only with default data.

Then, the spatial position of the line of sight in the detected direction is detected. That is, the spatial position of the line of sight is detected based on the spatial coordinate position of the eye of the person in the captured image and the detected direction of the line of sight. The spatial coordinate position of the eye is detected as follows. That is, the coordinates in the X direction and the Y direction shown in FIG. 2 can be detected by the coordinates in the photographed two-dimensional image, and the coordinates in the Z direction can be estimated from the size of the face, for example. And a method of detecting with a distance sensor. The coordinates in the Z direction may be calculated based on the time from when a predetermined light is emitted to when the light is reflected back on the face, eyes, and the like and returns.

As described above, the position of the line of sight in the space is determined based on the spatial position of the eye and the direction of the line of sight, so that the position of the line of sight on the display unit 20 is determined. Specifically, the coordinates (X, Y) as the line-of-sight position where the line of sight passes on the display surface of the display unit 20 are calculated.
When there is a line of sight outside the display surface of the display unit 20, the coordinates on the extension surface of the display surface are detected as the line of sight.

In the detection of the line of sight, it is preferable that a condition is determined as to whether or not a gazing point is detected. In other words, the processing is performed on the assumption that the line of sight has been detected for the first time when the line of sight has been stopped for a certain time. In other words, even if the line of sight is directed toward the display unit 20, if the line of sight does not stop for a certain period of time, it can be said that the displayed keyword is not perceived, and the line of sight is stopped for a predetermined period of time for line of sight It is desirable to make it a condition. The line-of-sight detection processing is performed by the line-of-sight detection unit 12.

The method of detecting the direction of the line of sight is not limited to the above method, but may be another method. For example, the detection of the presence or absence of a human face may be performed in the same manner as described above, and the detection of the line of sight may be performed based on the reflection angle by irradiating near-infrared light. Further, the above method and this method using near-infrared light may be used in combination. The coordinates in the Z direction may be detected based on the arrival time at which the near-infrared light is reflected and returned. The method of gaze detection is described in JP-A-8-322796 and JP-A-5-252.
No. 05030.

When the line of sight is detected as described above, it is determined whether or not a shift is detected by the shift detecting unit 16 (S12). That is, the detected gaze position is displayed on the display unit 2.
It is determined that there is a shift in the line-of-sight position when the frequency is outside the range of 0 or when the gazing point is biased toward a certain area. It is assumed that the information on the display range of the display unit 20 is stored in the shift detecting unit 16 in advance. In addition, it is determined that there is a gap even when the point of interest is gathered outside the display range of the icon while the screen displaying the icon is displayed. In this case, information on the display range of the icons is obtained from the display control unit 22. In this step S12, when a shift is detected, the process proceeds to step S13, and when no shift is detected, the process returns to the beginning. That is, the process returns to step S10.

Next, in step S13, a correction target is displayed. That is, the correction target is displayed on the display unit 20. The display of the correction target is performed by the display control unit 22. It is preferable that the correction target be large enough for the user to perceive the correction target, and that the color be different from the surrounding colors so that the user can easily perceive the correction target. In addition, the target may be blinked to draw the user's attention. In the example shown in FIG. 5, a correction target T indicated by a cross is displayed.

When the correction target is displayed, the line of sight at that time is detected (S14). This gaze detection is performed in the same manner as the gaze detection in step S11. That is,
The gaze position on the display surface of the display unit 20 is detected. Note that the gaze detection timing is obtained by the display control unit 22 displaying the correction target, giving a gaze detection instruction to the gaze detection unit 12 at a timing that takes into account the user's perception and a delay until the gaze is moved. In addition, the line of sight when the correction target is displayed is detected.

Then, the display position of the displayed correction target is compared with the detected line-of-sight position to detect a deviation between them (S15). That is, the shift direction and the shift amount between the line-of-sight position and the target position are detected.
As a method of detecting the shift direction and the shift amount, there is a method of detecting by comparing the shift amount in the horizontal direction (X direction) and the shift amount in the vertical direction (Y direction). That is, in FIG. 5, the coordinates of the correction target T are (x
α, yα), the coordinates of the detected line-of-sight position K are (xk,
In the case of yk), the shift amount in the X direction is represented by xα-xk, while the shift amount in the Y direction is represented by yα-yk.

After the deviation is calculated as described above, it is determined whether correction is necessary (S16). As a concept in this case, if the deviation amount is too large, the correction is not performed because there is a possibility that the displayed correction target has been missed. That is, the distance r between the correction target T and the line-of-sight position K is calculated, and if this r is smaller than a predetermined threshold, the correction is performed, while the distance r is larger than the threshold. If it is larger, no correction is made.

If it is determined that correction is necessary, the flow advances to step S17 to correct the line-of-sight position. That is, the image data at that time is captured and stored in the visual line detection information storage unit 14. In this case, if the position information of the coordinate position of the target position is not already in the position information of the default data, the registration is newly performed in the line-of-sight detection information storage unit 14. When the image data is stored in the visual line detection information storage unit 14, the visual line position in the table of FIG. 3 is the position information of the target position. That is, when the correction target is displayed at the coordinate position (xα, yα) as shown in FIG. 5, this (xα, yα) is written in the line-of-sight position of the table. And
The image data at this time is stored separately for horizontal density distribution information and vertical density distribution information. As a result, the information of the image data is used in the subsequent gaze detection.

On the other hand, when the position information of the coordinate position of the target position is already in the default data, a process for averaging the density distribution information of the image data is performed. For example, in FIG. 3, the line-of-sight position (x1, y1) and the line-of-sight position (xα, y
If α) is the same coordinate position, it is assumed that the content of the image data of the image data 1 is averaged instead of newly registering the image data α. That is, the density distribution information in the X direction is averaged for the image data 1 and the image data α, and the density distribution information in the Y direction is also obtained for the image data 1 and the image data α. Average things.

In the manner described above, in subsequent gaze detection, the degree of similarity with the averaged density distribution information is calculated to detect the gaze direction, so that more accurate gaze detection can be performed. . In addition, since the correction target is displayed and corrected during the processing in the computer terminal P, there is no need to perform calibration in advance.

In order to correct the density distribution information in the default data, it is preferable to set the line-of-sight position in the initially default data as the coordinate position of the correction target. . In the above description, step S10
From step S12, it has been described that the correction target is displayed when the displacement of the line-of-sight position is detected. However, the above-described displacement detection is not performed, and the correction target is displayed periodically. You may. The correction target may be displayed by a user's input operation.

Next, a second embodiment will be described. Second
The configuration of the detection line-of-sight position correction device A2 of this embodiment is substantially the same as that of the first embodiment, and has the same configuration as that of FIG. 1 except for the operation of the display control unit 22. That is, the display control unit 22 detects the display position of a certain input character, and sends information on the display position of this character to the shift detection unit 16. Further, at the timing when the character is displayed on the display unit 20, the gaze detection unit 12 is instructed to detect the gaze. The detailed operation will be described later.
The other configuration is the same as that of the first embodiment, and the description thereof is omitted.

The operation of the detection line-of-sight position correcting device A2 in the second embodiment will be described with reference to FIG. First, as shown in FIG. 2, it is assumed that the user is performing a process using the computer terminal P equipped with the detection line-of-sight position correction device A2 having the above configuration. This processing is arbitrary, such as input of characters by a word processor, processing by spreadsheets, and the like.

First, image data is taken into the camera by 10 (S20). That is, the camera 10 photographs the face of the user A. Then, the image captured by the camera 10 is sent to the visual line detection unit 12. Next, the line-of-sight detection unit 12 performs line-of-sight detection (S21).
The gaze detection method is the same as in the first embodiment.

After the line of sight is detected, it is determined whether or not a shift is detected by the shift detecting unit 16 (S22).
That is, it is determined that there is a shift in the line-of-sight position when the detected line-of-sight position is frequently outside the display unit 20 or when the gazing point is biased toward a certain area. It is assumed that the information on the display range of the display unit 20 is stored in the shift detecting unit 16 in advance. In addition, it is determined that there is a gap even when the point of interest is gathered outside the display range of the icon while the screen displaying the icon is displayed. In this case, information on the display range of the icons is obtained from the display control unit 22. In this step S22, when a shift is detected, the process proceeds to step S23, and when no shift is detected, the process returns to the beginning. That is, the process returns to step S20.

Next, in step S23, it is determined whether or not there is a character input. If there is a character input, the process proceeds to step S24. In step S24, the coordinates of the input position of the input character are detected. FIG.
Assuming that “LOGON” has been input as shown in (1), the coordinates of the display position of “LOGON” displayed on the display unit 20 are detected. The detected coordinates are (xα, yα)
And Note that the detected coordinates are “LOG
The coordinates of the position of the center “G” in “ON”.

When the coordinates of the character input position are detected, the line of sight at that time is detected (S25). This gaze detection is performed in the same manner as the gaze detection in step S21. In addition,
In actuality, the gaze detection timing is obtained by giving the gaze detection instruction to the gaze detection unit 12 at a timing in which the display control unit 22 displays characters, and considers the user's perception and the delay until the gaze is moved. It is preferable to detect the line of sight when the character is displayed.

Then, the display position of the character is compared with the detected line-of-sight position to detect a shift between them (S
26). That is, the shift direction and the shift amount between the line-of-sight position and the target position are detected. As a method for detecting the shift direction and the shift amount, the shift amount in the X direction and the shift amount in the Y direction are detected in the same manner as described above. That is, in FIG. 7, the coordinates of the input character L are (xα, yα)
In the case where the coordinates of the detected line-of-sight position K are (xk, yk), the shift amount in the X direction is represented by xα−xk.
The shift amount in the direction is represented by yα-yk.

After calculating the deviation as described above, it is determined whether or not correction is necessary (S27). Also in this case, similarly to the first embodiment, the distance r between the input character L and the line-of-sight position K is calculated, and if this r is smaller than a predetermined threshold, the correction is performed. If the distance r is larger than the threshold, no correction is performed.

If it is determined that correction is necessary, the flow advances to step S28 to correct the line-of-sight position. The method of this correction is the same as in the first embodiment.
That is, when the position information of the target position is not included in the position information of the already defaulted data, a new registration is performed in the line-of-sight detection information storage unit 14, while the position information of the target position is stored in the already defaulted data. If it is in the middle, a process of averaging the density distribution information of the image data is performed.

In the manner described above, in subsequent gaze detection, the degree of similarity to the averaged pattern image is calculated to detect the gaze direction, so that more accurate gaze detection can be performed. In addition, since the correction is performed by detecting the display position of the character input during the processing in the computer terminal P, it is not necessary to perform the calibration in advance. Further, according to the second embodiment, since the correction is performed in accordance with the shift between the display position of the input character and the detected line-of-sight position, it is necessary to display the correction targets one by one as in the first embodiment. Absent.

In the second embodiment, the description has been made assuming that the correction target is displayed when the displacement of the line of sight is detected, as shown in steps S20 to S22. Instead of performing the displacement detection as described above, the correction target may be displayed periodically.

In the above description, it has been described that the visual line detection information storage unit 14 stores image data separately into density distribution information in the X direction and density distribution information in the Y direction. However, the present invention is not limited to this. Instead, they may be stored as two-dimensional image data.

In the above description, the correction method is described as changing the density distribution information in the X and Y directions for a predetermined line of sight. However, the present invention is not limited to this. According to the shift direction and the shift amount,
A process of changing the information on the line-of-sight position in the table shown in FIG. 3 may be performed. That is, a deviation between a certain correction target and the detected line-of-sight position is detected in the X direction and the Y direction, and the coordinate information of the line-of-sight position stored in the table is corrected by the amount of the deviation.

That is, the deviation between the display position of a certain correction target and the detected line-of-sight position is detected in the X and Y directions, and the coordinate information of the line-of-sight position stored in the table is corrected by the amount of the deviation. is there. That is, in the example of FIG. 5, the shift amount in the X direction is xα−xk (this is xm).
On the other hand, the shift amount in the Y direction is represented by yα-yk (this is ym). Therefore, the data of the line-of-sight position already stored is corrected by this deviation amount. That is, in the case of image data 1, the line-of-sight position is (x
1−xm, y1−ym). It is preferable that the image data to be corrected be only default image data. In other words, image data other than the default image data is image data obtained by displaying the correction target, and thus the necessity of correction is low. In addition, the image data obtained by displaying the correction target increases as image data α and image data β. In this case, it is more appropriate to average the correction values.

[0047]

According to the gaze detecting apparatus according to the present invention,
Since the detected gaze position is corrected by displaying a correction target or a display such as an input character,
There is no need to perform calibration in advance.
