Abstract

A concave mirror optical system device on scanner and image distortion compensation method are disclosed. The present invention is to configure a concave mirror on the optical system of scanner for replacing the well-known optical system formed by lens. The present invention can eliminate the well-known achromatic effect generated by lens. Also, since the material is simple for the concave mirror of the present invention, the cost can be greatly reduced, and the magnitude can be varied based on the different degrees of focusing in the X-Y axis direction of the concave mirror.

Scanners are an example. In a few short years, the production of palm-type black and white scanners to today's full-color high-resolution scanners has produced The images are more refined and more realistic. There are two general scanner systems, one is a reflective scanner system and the other is a transmissive scanner system. In a reflective scanner system, a document (this document is an opaque document) is placed on a piece of transparent glass, and the light source shines on the document through the transparent glass, and then transmits the light through the document through a set of optical systems. Go to the optical sensor 'for example: a charge couple device (CCD) or a contact image sensor (CIS)' to form a scanned image. In the transmissive scanner system, the document (this document can be a translucent document such as a negative or a slide) is also placed on the transparent glass, and the light source passes through the document first, and then passes through the transparent glass and The optical system is transmitted to the optical sensor to form a scanned image. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs Please refer to Figure 1, which is a drawing of the conventional scanner system ^. When the reflective scanner system is to scan the document 40, the light emitted by the light source 38 on the sensing carrier 30 strikes the transparent glass 20, and this light is reflected by the document 40 and received by the sensing carrier 30 The slit 34 enters the sensing carrier 30, and finally transmits the light to the optical sensor 32 (CCD or CIS) through the optical system 36 (not shown in detail).

Description of the invention (7) (Please read the precautions on the back before filling this page The sensor 32 receives the light and converts it into image data to complete a scanning operation. Next, the sensing carrier 30 is displaced in the same direction along the transparent glass 20 and performs the next scanning action until all the documents are scanned into the image data by the reflective scanner system, and are used as reflective scanning. During the function of the device, the light source carrier 10 on the upper side does not operate. When a document 40 is scanned as a transmissive scanner system, the light emitted from the light source 12 in the light source carrier 10 is emitted by the light source slit 14 opened on the light source carrier 10, and this light passes through the document 40 and the transparent glass. The glass 20 enters the sensing vehicle 30 through the receiving slit 34 on the sensing vehicle 30, and finally transmits the light to the optical sensor 32 through the optical system 36 (not shown in detail), and the optical sensor 32 Receive this light and convert it into image data to complete a scan. Next, the light source carrier 10 and the sensing carrier 30 are displaced in the same direction along the transparent glass 20 and perform the next scanning action until all the documents are scanned into the image data by the penetrating scanner system, When functioning as a penetrating scanner, the light source 38 on the sensing carrier 30 does not emit light. Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs Please refer to Figure 2, which shows the optical system in the conventional scanner. The main purpose of the optical system 136 in the scanner is to transmit the image after the light source is irradiated to the document 140 to the optical sensor 132, and the optical system 136 includes at least a reflective lens 137 and a lens group 138, and a reflective lens 137 is used to change the traveling direction of the light, and the lens group 138 focuses the light onto the optical sensor 132, so that the optical sensor 132 can receive the data on the file 140.

Therefore, the present invention provides a concave mirror optical system device on a scanner, and the present invention constructs a concave mirror on the optical system of a scanner to replace the conventional optical system composed of a lens. The present invention provides a concave mirror optical system device on a tracer. The invention can effectively eliminate the color light separation effect produced by a conventional lens, and the concave mirror of the present invention can reduce the cost greatly due to the simple material. Different magnifications in the XY axis direction have different magnifications.

Please refer to FIG. 7, which shows the image distortion of the scanner optical system of the present invention. The compensation method is a device drawing view. In this embodiment, only a No. 3 concave mirror 550 is used as an example. Assuming that the optical system on the scanner is composed of only a No. 3 concave mirror 550, it is received by the optical sensor 560 during scanning. The image of the obtained file 540 is not a straight line, but a U-shaped graphic image. Therefore, after the scanning is completed, the U-shaped distortion will be displayed. In order to compensate for the distortion of the graphic, you can use it. It is restored by image distortion compensation method. First, before scanning, the image of the correction pattern 545 is converted into digital data through the A / D converter 570, and stored in the memory (ram) 600, and then the CPU 590 calculates the correction pattern. , The correct position of each pixel (Pixei), and generate the position correction data 580, so after the correction is completed, each scanned image is placed in the memory 600, and it can make each one according to the position correction data 580. The pixels are correctly arranged in the memory 600, so when the memory 600 is output, the image is a restored image and will not be distorted. Please refer to FIG. 8 'for a flowchart of the image distortion compensation method. First, obtain the image 61 of the corrected pattern, and then calculate the distance 620 between each pixel on the corrected pattern and the actual graphic pixel, and store the corrected distance gap 630 for each pixel. During scanning, according to the distance of the corrected pixel Gap, each pixel data is corrected and placed in the memory 640.
