  • Patent number: 8194290
    Abstract: An image compensating method. First, multiple scanning lines are used to scan a document and a longitudinal black and white pattern, in order to produce the actual gray level value for multiple pixels with respect to each of the scanning lines and the document, as well as a correctional gray level value for complete black and a correctional gray level value for complete white with respect to the longitudinal black and white pattern. Then, the compensational gray level value with respect to the actual gray level value for each of the pixels is obtained according to the correctional gray level value for complete black, the correctional gray level value for complete white, the theoretical gray level value for complete black, the theoretical gray level value for complete white, and the actual gray level value for each of the pixels. Then, the procedure is complete.

  • Patent number: 7903295
    Abstract: A method and a device for automatic capturing of a static image. The automatic static image-capturing device is a scanner. The method includes the following steps. Any changes on a scanning platform are monitored. If a change in the static image on the scanning platform is detected, the change is gauged for a preset time interval to check for any further change during this time interval. If no further change is detected within this time interval, a preset operation is triggered.

  • Patent number: 7489418
    Abstract: A high-resolution sensing method for a scanner having a motor and a charge coupled device. The charge coupled device further has m rows of sensors spaced a distance from each other. A motor with a moving speed equal to the width of one row of the sensors divided by an exposure time moves a distance equal to the width of one row of the sensors. During the exposure time, rows of the sensors are used to scan and to obtain image signals that have portions overlapped with each other. Therefore, by simply adding the number of rows of the sensors, the scanner has m times of resolution without changing the speed of the motor.

  • Patent number: 7466459
    Abstract: A method for enhancing scan resolution, suitable for the application of a scanner with a sensor. The range that a detecting cell in the sensor can detect is the original pixels with a predetermined number. The scanned result of the detecting cell is called the scanned pixels. In the method for enhancing scan resolution, a smooth image region is scanned to obtain a smooth image data. The smooth image region includes at least the above original pixels with the predetermined number. The smooth image region has a uniform brightness. According to the smooth image data, the scanned pixels obtained from scanning the document are processed.

  • Patent number: 7450769
    Abstract: An image processing method for facilitating data transmission is provided. An image compression method is performed to convert X-bits binary digital signals to a binary compressed data in the form of n*2m, in which n is represented by the former Y bits of the X-bits binary digital signals, m is set to the value of (X?Y), and represented by binary numbers with [log2(X?Y+1)] bits. The binary compressed data is transmitted with a sequence of [log2(X?Y+1)]+Y bits, representing (m, n), wherein m is the former [log2(X?Y+1)] bits and n is the latter Y bits. Therefore, by the present image compression method, the transmission amount of image data is reduced. The transmission time of image data and the volume of a memory for storing the image data are also reduced.

  • Patent number: 7406203
    Abstract: An image processing method for facilitating data transmission is provided. An image compression method is performed to convert X-bits binary digital signals to a binary compressed data in a floating-point form of (1.n)*2m. Bit m represents the first bit with logic level “1” of the X-bits binary digital signals, and n represents the bits taken from the X-bits binary digital signals after the bit m. The binary compressed data in the floating-point form of (1.n)*2m is outputted with a sequence of binary number representing a set of (m, n). The latter n bits of the sequence of binary numbers are consisted of the n bits of the X-bits digital signal. Therefore, by the present image compression method, the transmission amount of image data is reduced. The transmission time of image data and the volume of a memory for storing the image data are also reduced.

  • Patent number: RE42618
    Abstract: A multiple-field sensor for a scanner suitable for scanning a document. The scanner includes a multiple-field sensor, an average accumulator, and a block of memory. The multiple-field sensor has a plurality of sensing lines for each color channel. Each sensing line picks up a portion of image signal from the document during scanning. The sensing lines scan the same portion of the document to produce corresponding image signals. The average accumulator averages the image signals obtained from the sensing lines of the same color channel to produce an average image signal. The block of memory is used as a storage area for image signals in general and the average image signal in particular.
