Example 1

1 is a block diagram of a vehicle side display system using a camera prism for a vehicle side mirror according to an embodiment of the present invention.

Referring to FIG. 1, the vehicle side display system of the present embodiment includes first and second pyramidal prisms 102a and 102b, first and second lenses 104a and 104b, and first and second CCDs 106a and 106b. ), First and second image reconstruction blocks 108a and 108b, image synthesis block 110, and display panel 112.

First, the first and second pyramidal prisms 102a and 102b are, for example, left and right side mirrors 202a and 202b mounted on left and right sides of the vehicle 200, as shown in FIG. 2. It is mounted to the part or to replace the left and right side mirrors (202a, 202b), each of which has an equilateral triangular pyramid structure whose corners of the three sides form an angle of approximately 45 degrees. Here, for the convenience of explanation and improvement of understanding, it is assumed that the first pyramidal prism 102a is mounted on the left side of the vehicle and the second pyramidal prism 102b is mounted on the right side of the vehicle. That is, the first pyramidal prism 102a, the first lens 104a, the first CCD 106a, and the first image reconstruction block 108a constitute a means for acquiring the front and rear images of the left side of the vehicle, and the second The pyramid prisms 102b, the second lens 104b, the second CCD 106b, and the second image reconstruction block 108b form a means for acquiring the front and rear images of the right side of the vehicle.

In this embodiment, although the pyramidal structure having an equilateral triangle having an internal angle of 45 degrees is shown as an example, the present invention is not necessarily limited thereto, and if necessary, the vertex angle of the pyramid structure is larger or smaller than 45 degrees. Of course you can.

That is, the pyramidal prisms (for example, the first pyramid prisms 102a), as shown in FIG. 3 as an example, each reflecting surface (a1, b1) on the surface facing the front side and the rear side The reflecting surface b1 selectively projects only the image beams of any wavelength band among the image beams provided in the a direction (i.e., the front direction of the vehicle), while the image beam provided in the b (i.e., the rear direction of the vehicle) direction. Function to selectively reflect only an image beam of a specific wavelength band. Further, the reflecting surface a1 selectively projects only the image beams of any wavelength band among the image beams provided in the b direction (i.e., the rear direction of the car), while the image beams provided in the a (i.e., front direction of the car) direction. Function to selectively reflect only an image beam of a specific wavelength band. Here, the image beams reflected by the reflecting surfaces a1 and b1 are image beams of different wavelength bands.

Therefore, the image beam of a specific wavelength band provided in the front direction (a direction) of the vehicle is reflected through the reflecting surface a1 and travels in the direction of a2, thereby being transmitted to the A region of the first lens 104a, and the rear direction of the vehicle. The image beam of a specific wavelength band provided in the (b direction) is reflected through the reflecting surface b1 and travels in the direction of b2, thereby being transmitted to the B region of the first lens 104a. That is, in the present invention, the front and rear images of the side of the vehicle can be simultaneously obtained through one pyramid prism.

Next, the first CCD 106a photoelectrically converts an image beam provided through the first lens, that is, an image beam composed of left front and rear into a left image signal (ie, a left front and rear image signal), where The photoelectrically converted left image signal is transferred to the first image reconstruction block 108a of the next stage.

In addition, the first image reconstruction block 108a converts the left image signal provided from the first CCD 106a into a displayable image signal through the display panel 112, which will be described later. And reconstructing the rear image signal in the up and down directions, and the reconstructed left image signal is transmitted to the next image synthesizing block 110. At this time, in order to enhance the driver's recognition, it is preferable to arrange the front image signal upward and the rear image signal downward when reconstructing the front and rear image signals.

Meanwhile, in the above, the process of generating the left image signal consisting of the front image signal and the rear image signal by capturing the front and rear images of the left side of the vehicle is described. You can create the same process.

That is, the means including the second pyramidal prism 102b, the second lens 104b, the second CCD 106b, and the second image reconstruction block 108b may include the first pyramidal prism 102a and the first. The lens 104a, the first CCD 106a, and the first image reconstruction block 108a are technically identical to the technical means for generating the left image signal, and are functionally the same through the same technical means and functions. A video signal on the right side can be generated. Therefore, in order to avoid unnecessary duplication of description for the sake of brevity of the specification, detailed description of each means and processes for generating the right image signal is omitted here.

Next, the image synthesizing block 110 is provided from the left image signal (left image signal consisting of the front image signal and the rear image signal) provided from the first image reconstruction block 108a and the second image reconstruction block 108b. A composite video signal is generated by combining the right video signal (the right video signal including the front video signal and the rear video signal), that is, as shown in FIG. 4 as an example, as shown in FIG. 4, the left front video signal ( 402a and a left rear image signal 402b, and a composite image signal having a form in which a right front image signal 404a and a right rear image signal 404b are included in the right image area 404 is generated. Forward to 112.

On the other hand, the display panel 112 is, for example, a vehicle television monitor (for example, an LCD monitor), a vehicle navigation apparatus monitor, or a monitor separately mounted for the driver's side view, and is provided from the image synthesizing block 110. The composite video signal is displayed to be visually recognized by the driver.

Accordingly, the driver may monitor the traffic conditions of the left and right sides of the vehicle without blind spots through the composite image signal including the front and rear image signals on the left side of the vehicle and the front and rear image signals on the right side of the vehicle displayed on the display panel 112. We can watch clearly.
