Abstract

PURPOSE:To improve the reality of a picked-up object on a picture of a viewer by displaying a real size and a display magnification or the like. CONSTITUTION:When a photographer uses a camera 1 or the like to pickup an object, an image pickup information detection section 2 detects a distance (r) between a lens and an in-camera image reception element on an optical axis, a focus (f) of the lens, size of a pattern and a size (d) of an object on the in-camera image reception element as image pickup recording information and sends it to a processing section 4. The processing section 4 applies processing to form a frame by adding the pickup recording information signal with the picture information signal coded by the picture coding section 3 to, e.g. the information frame and using a line adapter section 6 via a control section 5 to connect to the line and sends it to the line. Thus, even when the size of the object is confirmed, the real size of the object is recognized by displaying the display magnification with respect to the real size of the object or varying optionally the display magnification.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is directed to a device that is photographed on a screen such as a display. There is a screen that displays an object to be photographed three-dimensionally on the screen to provide a sense of presence or reality.

Also, high definition, such as HDTV.

By displaying high-quality images, the shape of the object
There are also devices that perform screen display for the purpose of reproducing colors and the like on two screens in a state similar to the real thing.

[Problem to be solved by the invention]

However, in any of the above west facing displays.

The scale ratio of the actual size of the object to be photographed is determined by the conditions at the time of shooting or the screen size of the viewer. Even if you can change the dimensions, you don't know how many times the actual dimensions are, or the actual dimensions of the object being photographed.

Another problem is that the ratio between the displayed size and the actual size of the object to be photographed (hereinafter referred to as 5 display magnification) cannot be displayed on the screen, and the viewer cannot recognize the actual size of the object to be photographed.

An object of the present invention is to eliminate the above-mentioned problems and improve the sense of reality of the object on one screen on the viewer's screen.

[Means to solve the problem]

The present invention is.

(1) Display the object along with its actual size or display magnification, or display the object by arbitrarily changing the display magnification according to the will of the viewer. (2) The device has a database and its data From among these, one that is around us and whose actual size can be recognized empirically is automatically or arbitrarily selected and displayed on the screen at the same display magnification as the object to be photographed.

Do it like this.

(for production) By displaying actual dimensions, display magnification, etc.

It is possible to give a sense of reality to the shadowed object on the screen.

〔Example〕

FIG. 1 is a configuration diagram of a terminal showing an embodiment of the photographing side of the screen display processing method according to the present invention.

FIG. 2 is a configuration diagram of a terminal showing an embodiment of the viewer-side face display processing method according to the present invention.

FIG. 3 is an example of a terminal screen display.

This will be explained in detail below using two drawings.

In Fig. 1, ■ is a camera, 2 is a photographing information detection unit, and 3 is a camera.
4 represents an image encoding section, 4 a processing section, 5 a control section, 6 a line corresponding section, and 7 a line connection terminal. T! In FIG. 1, which shows the configuration of a shadow example, when a photographer takes a picture of an object with a camera 1, etc., he uses a known technique to capture an image on the optical axis between the lens and the image receiving element surface in the camera. Distance H (image path H: r), lens focal path jll (f), dimensions of the image plane (whip*horizontal; x*y), dimensions of the object on the image receiving element surface in the camera (d) The photographic information detection section 2 detects the information as photographic record information and sends it to the first processing section 4.

The processing unit 4 performs processing to configure a frame by adding, for example, the above-mentioned photographic recording information signal to an information frame along with the image information signal encoded by the 9-image encoding unit 3. The unit 6 connects to one line and transmits.

In FIG. 2, 8 is a line connection Hfm element, 9 is a line corresponding section, 10 is a signal detection section, 11 is a processing section, 12 is an image decoding section, 13 is a control section, and 14 is a storage section.

15 represents an input section, and 16 represents a display section. In FIG. 2, which shows the configuration of the viewing side, a signal detection unit 1° separates a photographic recording information signal and an image information signal from an information frame sent from the photographing side.

The image decoding unit 12 decodes one image information signal.

In the processing unit 11, the distance on the optical axis between the first most shadowed object and the camera lens (subject distance: L),
And the actual size (D) of the object to be photographed is calculated as follows.

r L r L ,', D=-Xd -r At the same time, the dimensions of the screen (display section) and the vertical and horizontal gain (to) are compared via the control section 13 and stored in the storage section 14 in advance. . For example, if the screen size in the vertical direction is
) and the display magnification (ε).

■ d δ δd f becomes.

(1) Select whether or not to display the display magnification on the 9-screen by operating the keyboard (input unit), and combine the above information with the image information signal decoded on the screen, as shown in Figure 3. Display on the display.

Alternatively, by changing the Φ value to ! Appropriately select the display magnification of the affected object on the ji plane.

It is also possible to change it.

(2) By operating the input unit, appropriate objects stored in the storage unit can be displayed simultaneously with the photographed object on the same screen at the same display magnification or at any display magnification, and the actual sizes can be compared.

Figure 4 shows a flowchart. When the leftmost route shown in Figure 4 is selected, a specific object to be photographed is selected in the currently displayed west face, and then the display magnification is displayed. An instruction is given, whereby a specific object to be photographed is displayed together with a display magnification. When the route shown in the center of FIG. 4 is selected, a specific object to be photographed is selected and the display magnification is entered numerically. As a result, the specific object to be photographed is displayed at the changed magnification.

Furthermore, if the rightmost route in Figure 4 is selected.

The user selects an object stored in a memory or the like in advance and then instructs the display position. This causes the object to be displayed on the screen. If you want to erase the display after any of the routes mentioned above, select "Display Erase" to erase the second display and return to the initial state.

〔Effect of the invention〕

As described above, according to the present invention, in a device having a single-screen display function, even when the viewer wants to check the dimensions of the object to be imaged, the display magnification can be set according to the intention of the viewer. By displaying , or by arbitrarily changing the display magnification, the actual size of the object to be photographed can be recognized. Also.

By superimposing familiar objects on the screen, you can check the dimensions of the object, which has the advantage of improving the sense of reality.
