摘要： The video coding system picks up the whole image of postal matter, inputs the picked image to a character/code & image reader to read a user code on the postal matter, prints bar code information corresponding to the read result on the postal matter, and sorts the postal matter according to the bar code information. In this system, a display device displays the whole image of postal matter from which the user code cannot be read, and user code candidate characters, together with a user code input area for inputting the user code, an image of a specific user code location, and images of a plurality of user code candidate areas. An operator inputs the user code, which the character/code & image reader failed to read, in the user code input area while visually checking the displayed whole image and the images of the user code candidate areas. The input user code is stored in a memory.

摘要： This invention utilizes the fact that a maximum density difference of pixels in a window within a predetermined range including a pixel of interest is large for a character region, and is small for a photograph region. A maximum density difference of an image within the predetermined region is calculated. A quantization error of pixels around the pixel of interest is calculated, and a correction amount is then calculated by proportionally distributing the quantization error in accordance with a feature amount calculated by a feature amount calculator. The correction amount is added to an image signal of the pixel of interest to form a compensation image signal, and the compensation image signal is quantized.

摘要： A image processing apparatus includes a dither processor, which converts an electrical signal representing a continuous-tone input image into a binary image singal by a dither method using a dither matrix. The binary image signal is stored in a memory, and supplied to a pixel-density conversion processor, which converts a pixel density of the binary image signal at a predetermined ratio, and generates a converted image with the pixel coordinates as defined by the conversion ratio. A pixel coordinate calculator calculates a coordinate position of each pixel of the converted image in the binary image, and selects a fiducial pixel. A reference pixel selector defines a window area on the binary image containing the fiducial pixel and corresponding in size to the dither matrix size, and extracts reference picture elements in the window area. A calculator calculates an average image-density of the reference picture elements and generates density data, which is binarized by a second dither processor by using a second dither matrix.

摘要： A feature-analyzing section determines whether a given picture element included in image information supplied from a line buffer represents a character portion or a photograph portion. In accordance with the determination made by the feature-analyzing section, a threshold value selection section selects either a threshold value calculated by a first threshold value calculation section, and to be used in relation to charcter portion, or a threshold value calculated by a second threshold value calculation section, and to be used in relation to photograph portion. By using the threshold value selected by the threshold value selection section, a binary-encoding section binary-encodes image information which is supplied thereto through a delay circuit. On the basis of the determination made by the feature-analyzing section, a determination section determines whether or not the given picture element represents a bold character portion. If the determination section determines that the given picture element represents a bold character portion, a selection section then selects a predetermined value supplied from a value generation section, in place of an output of the binary-encoding section.

摘要： A method and apparatus of electrophotography used for a printer or a copying machine, wherein a toner having no photoconductivity is applied on a surface of a photoconductive layer of a photoreceptor consisting of a transparent conductive layer and the photoconductive layer which are sequentially formed on a transparent substrate. The photoconductive layer is exposed from a side of the transparent substrate. Toner particles on an exposed region of the photoconductive layer are transferred to toner-receiving paper opposite the photoconductive layer so as to form a toner image. A process for developing a latent image can be omitted. In addition, a special toner such as a photoconductive toner having low sensitivity is not used, thereby forming a high-quality image.
