Embodiments of the present invention will be described below.

(First Embodiment) First, the principle of gaze detection will be described. FIG. 9 is a principle diagram (top view) of the gaze detection method, and FIG. 10 is a principle diagram (side view) of the gaze detection method.
It is. 9 and 10, 906a, 906b
Is a light source such as a light emitting diode that emits infrared light insensitive to the user. Each light source is substantially symmetric with respect to the optical axis of the imaging lens 911 in the x direction (horizontal direction) and in the y direction ( In the vertical direction), it is arranged slightly below (FIG. 10) and divergently illuminates the observer's eyeball. A part of the illumination light reflected by the eyeball is transmitted to the image sensor 912
Image. FIG. 8A is a schematic diagram of an eyeball image projected on the image sensor 912, and FIG. 8B is an output intensity diagram of the image sensor 912.

First, as shown in FIG.
The infrared light reflected from 06b illuminates the cornea 910 of the user's eyeball 908. At this time, a corneal reflection image d (virtual image) formed by the infrared light reflected on the surface of the cornea 910 is condensed by the imaging lens 911 and the image sensor 912
An image is formed at the upper position d '.

Similarly, infrared light emitted from the light source 906a illuminates the cornea 910 of the eyeball. At this time, a corneal reflection image e formed by infrared light reflected on the surface of the cornea 910
The (virtual image) is condensed by the imaging lens 911 and forms an image at a position e ′ on the image sensor 912.

When the rotation angle θ of the optical axis of the eyeball 908 with respect to the optical axis of the imaging lens 911 is small, the x-coordinates of the single parts a and b of the iris 904 are xa. , Xb, xa and xb can be obtained on the image sensor at a number of points (x marks in FIG. 8A).

First, the pupil center x is calculated by the least square method of the circle.
Calculate c. On the other hand, assuming that the x coordinate of the center of curvature o of the cornea 910 is xo, the rotation angle θx with respect to the optical axis of the eyeball 908
Is as follows: oc * sin θx = xc−xo (1) Here, o 'is the center of the eyeball. In addition, xo is determined at the midpoint k between the corneal reflection images d and e in consideration of a predetermined correction value δx.
Xk = (xd + xe) / 2 xo = (xd + xe) / 2 + δx (2) Here, δx is a numerical value obtained geometrically from the installation method of the apparatus and the eyeball distance, and the calculation method is omitted. . When (1) is substituted into (2) to obtain θx, θx = arcsin [[xc − ｛(xd + xe) / 2 + δx}] / oc] (3) Further, the coordinates of each characteristic point projected on the image sensor Similarly, θx = arcsin [xc ′ − {(xd ′ + xe ′) / 2 + δx ′}] / oc / β] (4) Here, β is a magnification determined by the distance sze of the eyeball to the imaging lens 911 and is actually obtained as a function of the interval | xd′−xe ′ | of the corneal reflection image. In addition,
a'b 'is the edge of the pupil formed on the image sensor 912.

When viewed from a vertical plane, the configuration is as shown in FIG. Here, corneal reflection images generated by two infrared light emitting diodes (hereinafter referred to as IREDs) 906a and 906b are generated at the same position, and this is set as i.

The method of calculating the rotation angle θy of the eyeball is substantially the same as that in the horizontal plane, but only the equation (2) is different. If the y coordinate of o of the corneal curvature center is yo, then yo = yi + δy (5) Where δy is a numerical value obtained geometrically from the arrangement method of the apparatus, the eyeball distance, and the like, and its calculation method is omitted. Therefore, the vertical rotation angle θy is as follows: θy = arcsin [[yc ′ − (yi ′ + δy ′)] / oc / β] (6)

Further, when the position coordinates (xn, yn) on the finder screen of the video image pickup device are determined by using a constant m determined by the finder optical system, the position coordinates (xn, yn) on the horizontal plane and the vertical plane are obtained. Xn = m * arcsin [xc ′ − {(xd ′ + xe ′) / 2 + δx ′}] / oc / β] (7) yn = m * arcsin [[yc ′ − ｛(yi '+ Δy')] / oc / β] (8), and the position of the line of sight is determined.

As apparent from FIG. 8A, the pupil edge is detected using the rising edge (b ') and the rising edge (a') of the image sensor waveform. Further, the coordinates of the corneal reflection image use sharp rising portions (e ′) and (d ′).

The individual difference correction system will be described. In an actual observer's eye, the ac dimension in the equation (1) varies, and the optical axis and the support axis of the eyeball are displaced. In consideration of these, it is necessary to measure the special data of each user and set each data at the time of photographing in order to further improve the accuracy of the eye gaze detection.

A method of using the proportional constant A and the offset constant B as user characteristic data as an individual difference correction system will be described. Assuming that a proportional constant A and an offset constant B are separately set in the horizontal direction and the vertical direction with respect to the line-of-sight coordinates obtained by the equations (7) and (8), and the corrected coordinates are (Xnt, Ynt). Xnt = Ax * Xn + Bx (9) Ynt = Ay * Yn + By (10), and the visual line detection is corrected.
