Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image input method for a color image input device.
In particular, the present invention relates to an image input device configured to obtain a desired color video signal using a three-color separation filter of light and the rotational force of a motor.

[Conventional technology]

The configuration of a conventional color image input device is shown in a block diagram in FIG. As shown in Fig. 4, the conventional color image input device uses a three-color separation filter (R, G, and G as an example in the figure).
, B filter), three conversion devices for processing and converting signals, and a storage device were required. As another example, a configuration has been adopted in which each device has one input device, one conversion device, and one storage device, separates light into three colors by moving a filter, and inputs signals as needed.

[Summary of the invention]

The present invention provides a color image input device in which a rotating plate equipped with a three-color separation filter is arranged, the rotating plate is rotated at an appropriate speed, and a video signal is inputted at a focal speed, thereby producing clear colors. Enables color image input without deviation,
Moreover, it has been made smaller and lower in price.

[Problem that the invention seeks to solve]

However, the above-mentioned conventional technology requires three input devices each having the same configuration except for the filter, and a conversion device, resulting in a large device, resulting in poor operability and mobility. The high cost of color image input devices has been a major obstacle to the widespread use of color image input devices. In addition, if the apparatus has one input device and one conversion device, and inputs color signals at any time due to the movement of the filter, there is a problem that if there is a time interval between inputs, a shift in the image will occur.

Therefore, the present invention has been devised to solve the above-mentioned problems, and its purpose is to miniaturize the system and provide an inexpensive image processing system with excellent operability and mobility. By realizing an input device and subsequently inputting three-color separation signals of light, it is possible to input a clear image without deviation.

[Means for solving problems]

The color image input device of the present invention includes an input device such as a video camera that inputs an image, a conversion device that converts or processes a video signal into an appropriate format, and a storage device that stores the converted signal. In the apparatus, a rotating plate equipped with a three-color separation filter for light is arranged in front of the input device, and the three-color separated video signal is input by rotating the rotating plate at an appropriate speed. [Function] According to the color image input device configured as described above,
If a rotary plate with three color separation filters attached is placed in front of the input device and rotated continuously at an appropriate speed, there is no need to adjust the digits of the three color filters each time an input is made, and the input time is saved. Can be shortened. Furthermore, there is no need to control the nine rotations of the rotary plate, making it possible to input color images extremely easily.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

In FIG. 1, a video camera I of a color image input device
A rotary plate 3 of an RGB S color light separation filter attached to a motor 2 is arranged in front of the .

An optical sensor 4 is located between the video camera 1 and the motor 2. The image inputted by the input camera is transferred as a video signal to the conversion device 5, and the video signal is data-processed by the conversion device 5 and converted into data to be stored in the storage device 6. The optical sensor 4 detects the R of the rotating plate 3 which is continuously rotating.
Used for digit 1 detection of GB filter. For example, in FIG. 2, when the RGB filters are arranged on the rotary plate 3 as shown in the figure, one hole is provided inside the filter of the rotary plate 3 at the starting position of the R filter 8, Filter 9
Two holes are provided at the starting position of the B filter 10, and three holes are provided at the starting position of the B filter 10.

The optical sensor 4 determines the position and type of the RGB filter based on the position and number of the holes while the motor 2 is rotating, and starts inputting the image when the filter of the desired color comes in front of the lens 7. do. Since the rotary plate 4 rotates at high speed, the position of the filter of a desired color can be detected instantaneously. In the figure, the rotation direction of the rotary plate 4 is as follows:
This is the direction indicated by arrow 11.

In the embodiments described above, image input by the color image input device can be realized by a circuit block as shown in FIG.

That is, the input of the incident light 12 is passed through the R filter 8. G filter 9. The configuration is such that the data is passed through the B filter 10, inputted to one input device 13, subjected to data processing and data conversion by one conversion device 14, and stored in the fourth Lt device 15.

〔Effect of the invention〕

As described above, the present invention allows color images to be easily input using a simple configuration in which a three-color separation filter for light is placed in front of an input camera. At this time, the color image input device system can be made smaller and lower in price.

In addition, by rotating the rotary plate at high speed, it is possible to capture images at high speed, and it is possible to obtain clear images without deviation.
