摘要： An image scanner that can extract the information of interest from a document at high speed, using a relatively small-scale circuit arrangement that provides an image processing performance equal to that obtained by applying convolution to a larger number of pixels. Light reflecting from the document is converted to electrical image signals by a one-dimensional image sensor. After these image signals have been digitized by an A/D converter, they are input to an adder. A portion of the digitized signals is input to a rounding circuit in which the average intensity of a pixel unit, each comprised of a prescribed number of pixel groups, is calculated. These units are treated as pseudo pixels on which convolution is performed by a convolution integrator. A subtracter is then used to obtain the difference between signals input from the A/D converter and signals output by the convolution integrator. This is then used to obtain the difference between the intensity of the pixel of interest and the average intensity of the prescribed number of surrounding pixels to effectively distinguish alphanumeric characters and other such information, from the background.

摘要： A document image scanner that converts scanned images for output as bilevel images is provided with a bilevel image filter. The bilevel image filter counts the number of continuous pattern elements in each direction, vertical, horizontal and diagonal, from a specific point and compares the results with a predetermined reference. Patterns falling below the reference value are regarded as resulting from background noise and are erased.

摘要： In a document for sensing information, while the document to be sensed is fed in one direction, both surfaces of the document are illuminated by the respective sources of light. Light reflected by one and then the other surface of the document alternately reach a one-dimensional image pickup element. The light sources may be turned on and off. Alternately, the sources of light may be left on, in which case light reflected by both surfaces of the subject are intermittently interrupted.

摘要： An image scanner is provided that receives light reflected from a same position on a document by first, second, and third one-dimensional image sensors arranged in parallel. The second image sensor is a high-resolution image sensor comprising a plurality of photocells, which is disposed between and in a spaced-apart relationship with the first and third one-dimensional image sensors which are each low-resolution image sensors comprising photocells which are larger in size than the photocells of the second one-dimensional image sensor. Electrical image output signals from the first and third low-resolution image sensors are added, and any high-frequency components in the added signal are removed by a low-pass filter for producing signal data relating to the mean brightness of the region around a pixel of interest. The difference between the mean brightness and the brightness of the pixel of interest, as outputted by the second high-resolution image sensor, is then derived to produce an output signal in which points to where the brightness changes in the image are emphasized. Subsequent processing enables textual and other information of interest in the document to be extracted from background information.

摘要： An image binarization system in which the threshold value used for the binarization process can be adjusted to thereby enable the process to be made more accurate and avoid loss of black areas in characters in the process of digitizing and conversion. The threshold value is based on the average value of pixel density values around the pixels to be binarized, and is corrected downward when the average density value of the surrounding pixels is larger than a specific boundary value, and upward when the average value is smaller than the said boundary value.
