Abstract

PURPOSE:To facilitate the adjustment of the position of a liquid crystal display picture and the position of a camera by providing a moving part varying an angle of observing a liquid crystal display section and a moving part varying an angle of a pickup section picking up its own picture and displaying the self picture onto part of the liquid crystal display section. CONSTITUTION:A moving part 4 for a liquid crystal display section is moved forward/backward by turning a knob 5. Moreover, a pickup section 2 is moved vertically by turning a knob 3 fitted to a side face of the pickup section 2 to cope with a moving object such as a person. A moving part 4 for a liquid crystal display section is moved forward/backward to provide an optional tilt by turning a moving knob 5 thereby varying the visual angle. Thus, the direction of the liquid crystal display screen and the camera is set to a best position by using the moving mechanism. Then the operability is remarkably improved in reference to the human behavior pattern.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a self-imaging device suitable for use in image processing devices such as videophones and image input devices that display a self-image on a liquid crystal display. be.

(Summary of the Invention) The present invention has a movable part for changing the viewing angle of a liquid crystal display section and a movable part for changing the angle of an imaging section for photographing a self-image, and the self-image is displayed as a part of the liquid crystal display section. The present invention relates to a display self-imaging device.

(Prior Art) Conventionally, in videophones and the like, a cathode ray tube has been used as a display screen, but when changing the angle of the imaging section, the position of the device must be changed.

(Problems to be Solved by the Invention) In the conventional device as described above, when displaying a liquid crystal, the color, contrast, etc. of the image appear different depending on the viewing angle due to the viewing angle dependence of the liquid crystal. Therefore, viewers had to make various efforts to get a better view by changing the position of the equipment or moving their bodies.

Similarly, they tried to move the camera position, the position of the device, the position of the body, etc. to get a better picture.

As a method of self-monitoring, a method of viewing using a two-screen display has been proposed, but in a two-screen configuration, the main screen is large and the self-screen is often displayed small, about 1/3 of the size. In this case, memory address control, data compression control, etc. were complicated, the circuit configuration was large, and the screen size could not be determined arbitrarily.

(Means for Solving the Problems) The self-imaging device of the present invention has the following features in order to make the liquid crystal display easier to read:
A mechanism is provided for the display unit to move forward and backward, and a mechanism is provided for the camera to move independently from the display unit.The self-monitor is a two-screen display, and the display size is set using the memory brain data equivalent to the entire display screen. The structure is determined by the following.

(Function) The directions of the liquid crystal display screen and the camera can be set to the best positions by the respective movable mechanisms, and thereby the operability can be significantly improved even in light of human dynamic behavior patterns.

Furthermore, by determining the display size using the memory brain, the display size can be freely selected and the screen configuration can be tailored to suit the device.

(Embodiment) Hereinafter, an embodiment of the self-imaging device of the present invention will be described in detail with reference to FIGS. 1 to 3.

Figure 1 shows an external view of this device. This device consists of a main telephone set 6, a handset 7, and a liquid crystal display movable section 4 incorporating a liquid crystal display section 8 and an imaging section 2. The liquid crystal display movable part 4 can be moved back and forth by turning a knob 5. Further, the imaging section 2 can be moved within the imaging window 1 by turning the knob 3.

Figure 2 shows the structure of the movable part of this device. FIG. 2 is a side view of the device. By turning a knob 3 attached to the side surface of the imaging section 2, the imaging section 2 can be moved up and down, making it possible to handle dynamic subjects such as humans.

The movable part 4 for the liquid crystal display section can be moved back and forth by turning a movable knob 5 to give an arbitrary inclination.
It is possible to change the viewing angle.

A gear 15 inside the main body telephone 6 is attached coaxially with the knob 5, and rotation of the gear 15 can be stopped by a gear stop 16 also inside the main body 6. By stopping the rotation of the gear I5, it is possible to fix the front and back inclination of the liquid crystal display movable section 4.

Figure 3 shows the part of this device that combines a photographed self-image and an image from the outside and displays it on the liquid crystal display. FIG. 2 is a block diagram of a circuit showing the configuration.

Imaging camera 18 (in FIGS. 1 and 2, the imaging unit 2
) is converted into a digital signal by an A/Di converter 19. At the same time, the write address generator 22 is operated at the timing of the synchronization signal taken out by the synchronization separation circuit 20, and the self-image is written into the memory 21.

On the other hand, the video signal input from the external input terminal 24 is converted into a digital signal by the A/D converter 25, as in the case of the self-image. At the same time, the write address generator 28 is operated at the timing of the synchronization signal taken out by the synchronization separation circuit 26, and the external input image is written into the memory 27.

In order to read the self-image written in the memory 21 and the external input image written in the memory 27, the terminal 24 is used.
The contents of the memory are read by operating the read address generator 23 and the read address generator 29 at the timing of the synchronization signal extracted by the synchronization separation circuit 26 from the video signal input from the memory.

When displaying an image from the outside on the liquid crystal display section 8, a self-image taken with the imaging camera 18 can be synthesized at the lower right corner of the liquid crystal display section 8 at one-fourth the size of the external human-powered image. It is read out by the read address generator 23.

In order to synthesize two screens, the memory data that has been read out as described above is switched by the switch 32 and the images are synthesized. The switching timing is such that a 1-bit memory brain called a mask memory 30 is read out by the read address generator 29 at the same timing as the external input image memory 27. The data read from the mask memory is used as a switching signal for the switch 32. Among the bit data in the mask memory 30, the bit data for the part where the self-image is synthesized is the part indicated by the code 31.

31, the terminal 33 and terminal 35 in the switch 32 are connected, and the self-image is connected to the terminal 3.
Output from 5. Further, when the bit data is not the part 31, the terminal 34 and the terminal 35 in the switch 32 are connected, and the external input image is output from the terminal 35. The output of the terminal 35 is converted into an analog signal by the D/A converter 36, and then displayed on the liquid crystal display section 8.

Furthermore, by changing the size of the bit data 31 for self-image composition in the mask memory 30, it is possible to vary the display area of the self-image to be synthesized on the liquid crystal display section 8.

(Effects of the Invention) Since the self-imaging device of the present invention has the above-described configuration, it has the advantage that the position of the 1α crystal display screen and the position of the camera can be easily adjusted. Furthermore, since the self-monitoring screen size can be determined arbitrarily, a display size suitable for the device can be configured, which has the effect of improving operability and recognition.
