Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing camera, and more particularly to an image processing camera capable of obtaining a high-resolution color image, a low-resolution image, and distance information with one CCD.

[0002]

2. Description of the Related Art Conventionally, when detecting an object in an image processing system such as a surveillance camera or a reception system, it is general to use shape information, color information, distance information, and motion information. Shape information, distance information, and motion information are extracted from high-resolution and low-resolution monochrome images, and color information is extracted from high-resolution and low-resolution color images. The distance information is extracted from the images of the two cameras at a certain distance. In order to simultaneously obtain shape information, color information, distance information and motion information, the one shown in FIG. 5 has been proposed.

In FIG. 1, this image processing system comprises:
It comprises high-resolution color cameras 51a and 51b, an image processing device 52, and an image output device 53. High-resolution color images are obtained from the high-resolution color cameras 51a and 51b and sent to the image processing device 52. In the image processing device 52, the color information is input from the input high-resolution color image, the shape information, the motion information, and the high-resolution color camera 5
Distance information is extracted from the two high-resolution color images captured in 1a and 51b.

[0004]

When such an image processing camera is used as an input device for introducing a security system image processing apparatus as an additional function such as a surveillance camera or a door phone, two image processing cameras must be prepared. There were drawbacks such as being expensive and difficult to introduce. Also,
There were drawbacks such as difficulty in securing space for two units.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a low-cost, space-saving image processing camera capable of simultaneously obtaining a high-resolution color image, a low-resolution image, and distance information with one CCD. It is intended to be.

[0006]

To achieve this object, an image processing camera according to the present invention comprises a color CCD, a high-resolution lens for obtaining a color high-resolution image, and a low-resolution image for obtaining a low-resolution image and distance information. It has a semi-cylindrical lens, a right-angle prism and a reflecting mirror for forming an image of each lens on a color CCD at a predetermined position. In this image processing camera, a single camera can simultaneously obtain a high-resolution color image, a low-resolution image, and distance information, and can be used for a monitoring camera, a reception system, and the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an image processing camera according to the present invention will be described below with reference to the drawings. FIG. 1A is a side view of the image processing camera according to the present invention, and FIG. 1B is a front view of FIG. 1A. FIG. 2 is a configuration diagram of an image processing system using the image processing camera according to the present invention.

1 (a) and 1 (b), an image processing camera includes a color CCD 15, a high resolution lens 12 for obtaining a color high resolution image, and a kamaboko type lens for obtaining a low resolution image and distance information. 11a, 11b, 11c,
11d, and right-angle prisms 13a, 13a, 1b for forming an image of each lens on a color CCD 15 at a predetermined position.
3b, 13c, 13d and reflecting mirrors 14a, 14b, 14
c, 14d. 2, the image processing system includes an image processing camera 21, an image processing device 22, and an image output device 23.

[0009] Kamaboko type lenses 11a, 11b, 11
Lenses 11a and 11 arranged vertically above c and 11d
b denotes a lens having a wide angle in the vertical direction, and lenses 11c and 11d disposed in the left and right have a lens having a wide angle in the left and right. The right-angle prisms 13a, 13b, and 13c each have a common part in the imaging range. , 13d and reflector 14
The adjustment is performed using a, 14b, 14c, and 14d.

As shown in FIG. 3 (b), the image processing camera 21 includes a high-resolution color image 33 at the center of the image, a camera lens image 32a at the top, bottom, left and right as shown in FIG. The image in which 32b, 32c, and 32d are arranged is output to the image processing device 22.

A high-resolution color image is obtained by cutting out the high-resolution color image 33 at the center of the screen in the image processing device 22, and a low-resolution image is obtained by performing a distortion correction on the image of the lens of the type placed vertically and horizontally. A resolution image is obtained. Further, since there is a common portion in the imaging range of the Kamaboko-type lens image, as shown in FIG.
When photographing the photographing target object 47 in a state where the lens 45 is mounted on the CD 45, the corresponding point of the image after the distortion correction for each lens 46 is searched to obtain the parallax 41, and the obtained parallax 41 and The known distance between the lenses 42 and the focal distance 43 are the distance between the lenses 42: parallax 41 = the distance 44: the focal distance 43, so that the distance 44 can be obtained.

[0012]

As is apparent from the above description, according to the image processing camera of the present invention, since the camera-type lenses are arranged on the upper, lower, left and right sides of the high-resolution lens, a single CCD can provide a high-resolution color image and a low-resolution image. A resolution image and distance information can be obtained at the same time.
