Abstract

In the present invention, a scanning instrument has a motor and one CCD device of m lines of sensors separated by the distance of 1 line. During sensing, the motor in the speed of sensing line width divided by the 1 exposure time moves the distance of one sensing line width. During the exposure, m lines of the sensors are used to sensor several crossed scanning image signals. Therefore, increasing the number of sensor lines can raise the resolution of the scanning instrument by m time without needing change the speed of the motor.

Description

The high-resolution sensing method of scanner
Technical field
The invention relates to a kind of method for sensing of scanner, and particularly relevant for a kind of high-resolution sensing method of scanner.
Background technology
The scanner scanning file is the luminous intensity of coming the reflection of sensing file by the charge coupled device in the scanner, charge coupled device (Charged Coupled Device) can be done gray scale scanning, also can do chromoscan, its scanning is all come the luminous intensity of sensing file reflection by permutation transducer (Sensor), be the configuration diagram of plain scan instrument as Fig. 1.
In Fig. 1, stepper motor (Step Motor) 102 moves carrier (Chassis) 108 distance (being the width of the biographies sensor in the charge coupled device 104) of an optical resolution, the light that fluorescent tube 106 sends is incident upon on the file 110, the light that file 110 is reflected is via speculum (Mirror) 112, lens (Lens) 114 and transducer 116 in the charge coupled device 104,118,120 (transducers 116,118,120 can be sensing R, G, the trichromatic transducer of B), charge coupled device 104 is delivered to late-class circuit (not drawing) with the picture signal of institute's sensing again and is done signal processing.Then, stepper motor 102 moves carrier 108 distance of an optical resolution again along the scanning direction, according to above-mentioned step, charge coupled device 104 is delivered to late-class circuit (not drawing) with the picture signal corresponding to file 110 next columns of institute's sensing again and is done signal processing.Step so, scanner 100 just can scan the view data that obtains whole part of file 110.
Scanner 100 is when scanning document 110, and in order to improve the resolution of scanning, then the optical resolution of stepper motor 102 also increases sometimes, and promptly the distance of stepper motor 102 each mobile carriers 108 shortens.With general resolution is example, and the stepper motor 102 of 1 times optical resolution is to move for 1 step at 10ms, and then the rotating speed of stepper motor 102 is 100pps; If the stepper motor 102 of 16 times optical resolution is to move for 16 steps at 10ms, then the rotating speed of stepper motor 102 is 1600pps.So when the resolution of scanner 100 heals when high, then the speed fluctuation of stepper motor 102 is just bigger, therefore, utilize the change of stepper motor 102 speed to change the resolution of scanner 100, the stepper motor 102 that change speed is big is unusual difficulty in design, and cost relatively increases.
Summary of the invention
Therefore the high-resolution sensing method that the purpose of this invention is to provide a kind of scanner, the speed that it can not change the speed of stepper motor or can significantly not change stepper motor, as long as increase the number of sensor column, just can make scanner have high-resolution function, so stepper motor does not have the problem of difficult design and cost increase.
The invention provides a kind of high-resolution sensing method of scanner, with so that scanner has the function of m resolution, this scanner has a motor and a charge coupled device, and this charge coupled device has m biographies sensor, and this m biographies sensor is poor at a distance of a line respectively.The step of the high-resolution sensing method of this scanner is: at first, be the width of 1 row sensing row moves the width of 1 row sensing row divided by the motor of a time for exposure distance by translational speed.And, in this time for exposure, respectively by at a distance of several interlaced image signals of m biographies sensor sensing of line difference for this reason.
The invention provides the high-resolution sensing method of another kind of scanner, be to use so that scanner has the function of m+1 resolution, this scanner has a motor and a charge coupled device, and this charge coupled device has m biographies sensor, and this m biographies sensor is poor at a distance of a line respectively.The step of the high-resolution sensing method of this scanner is: at first, be [m/ (m+1)] times width of 1 row sensing row moves [m/ (m+1)] times width of 1 row sensing row divided by the motor of a time for exposure distance by translational speed.And, in this time for exposure, respectively by at a distance of several interlaced image signals of m biographies sensor sensing of line difference for this reason.So, in the speed that does not change stepper motor or can significantly not change the speed of stepper motor,, just can make scanner have high-resolution function as long as increase the number of sensor column.
