Description

  The present invention relates to high magnification electronic binoculars.

With a high-magnification telescope (telescope with a magnification of 10 to 100 times), you can prevent camera shake by preparing a tripod, but you can point the high-magnification telescope accurately at the object you want to observe manually, It was very difficult and practically impossible to focus on.
In particular, when a moving object is viewed with binoculars as in sports watching, it is very difficult to follow the moving object into the field of view of the binoculars and to focus.
High-magnification binoculars have been pointed out as having the disadvantages of the prior art such that the pupil diameter is small and the observed image is dark and difficult to see.
Regarding the telephoto zoom function, binoculars equipped with a telephoto zoom function become heavy, and it was believed that the telescope was the first to be easily carried.

High-magnification binoculars have been pointed out as having the disadvantages of the prior art such that the pupil diameter is small and the observed image is dark and difficult to see.
Regarding the telephoto zoom function, binoculars equipped with a telephoto zoom function become heavy, and it was believed that the telescope was the first to be easily carried.
That is, the shortcomings of the prior art of high magnification binoculars are listed as follows.
(1) Camera shake cannot be prevented, and the screen vibrates and eyes are tired.
(2) Since the pupil diameter is small, the observed image is dark and difficult to see.
(3) Since binoculars equipped with a telescopic zoom function are heavy, the telescope cannot be easily carried.
(4) It is very difficult and practically impossible to accurately point the high-magnification telescope at an object to be manually observed or to manually focus on the object.

The conventional defect (2) can be dealt with by increasing the diameter of the high-power binoculars and increasing the pupil diameter.
For the conventional defect (3), binoculars equipped with a telescopic zoom function become heavy and the telescope cannot be easily carried. However, even if it becomes heavy, there is no problem if there is a function of high magnification binoculars that surpasses that. it is conceivable that.
In addition, if a telephoto zoom lens is installed, high-power binoculars become heavier, but if a variable focal length lens is used, it is necessary to focus. However, focusing on the object with the help of the machine If the high-magnification telescope is used, the disadvantage of the prior art that the high-magnification binoculars become heavy is eliminated.
The conventional drawback (4) cannot be handled with a manually operated high-power telescope, and the high-power telescope can be accurately pointed at an object to be observed with the help of a machine. A high-power telescope that can focus on an object with the help of a machine can be realized.

The coordinates of the point P2 are represented by (x1, y1).
Point P2 corresponds to a point translated from point P1 by Δ (cm) in the x direction.
x2 = x1 + Δx, y2 = y1 (1)
The observation image data G01 is the image G1 within the set observation region SO1 or a converted image of the image G1 in the image G1 (for example, when the image G1 is a color image, the color image G1 is converted into a grayscale image. Image). The number of pixels of the image G1 in the observation region SO1 is N, and is represented by G01 (1) to G01 (N).

The observation region SO2 refers to a peripheral region of the point P2 having a characteristic image of the object Ojt to be observed around the point P2 set by the phase difference detection device DU. The case where it is a rectangle, a circle, or an ellipse similarly to the point P1 is illustrated.

● Pixel means the smallest unit element constituting an image.
● The number of pixels refers to the total number of pixels in the image.
● Pixel value refers to a numerical value representing the intensity or color of light of each pixel.
The pixel values of the observation image G01 and the observation image G02 are converted from the images G1 and G2 and given as one numerical value (natural number or real number). For example, when the image G1 is a color image, the brightness of the image obtained by converting the color image G1 into a grayscale image is one numerical value (natural number or real number).
(1) Color image
In a color image, the color of one pixel is represented by three primary colors of R (red), G (green), and B (blue). A 24-bit image in which each RGB element of one pixel is represented by 8 bits is often used. That is, in a 24-bit image, one pixel is composed of 24 bits (8 bits × 3 colors).

The pixels G01 (1) to G01 (N) of the image G01 are not related to the x-direction displacement Δx, but the pixels G02 (1) to G02 (N) of the image G02 are dependent functions related to the x-direction displacement Δx. is there.

The inventor observes with a pointing device PD (for example, a mouse) without specifying, for example, an image processing operation for extracting a contour line of the image of the object in order to specify the object image of the images G1 and G2. By pointing and inputting a point (point to be focused) P1 to be set, setting an observation region SO1 centered on the point P1, and acquiring observation image data G01 that is an image G1 in the observation region SO1, Notice that the observed image data G01 can be equated with the image of the object Ojt (the outline of the object Ojt),
In the image G2, the point P2 (x2, y2) is set so as to satisfy the expression (1), the observation region SO2 centered on each point P2 translated from the observation region SO1 is set, and the observation region SO2 is set. The observation image data G02, which is the image G2 in FIG. 2, is acquired, and the displacement Δ (cm) is changed to obtain the displacement Δ in which the observation image data G01 and the observation image data G02 match, that is, the phase difference ΔX (cm).

It is divided into binocular and monocular, and there are types such as “immersive type” (non-transmission type) and “transmission type” that completely cover the eyes. It can also be classified into 3D / 2D.
The distance LD refers to a distance (cm) from the high magnification electronic binoculars 100 according to the present invention to the object Ojt. Strictly speaking, the distance LD refers to the distance (cm) from the focus lens FL constituting the high-magnification electronic binoculars 100 to the object Ojt.
