    摘要： In a data processor, in order to perform coding efficiently, image data of a prescribed pixel matrix is subjected to orthogonal transformation to coefficient data. Obtained coefficient data is quantized with a first quantization table for character image, and they are also quantized with a second quantization table for half-tone image. Then, the image data is discriminated to be a character image data or a half-tone image data according to the two quantization data. Then, quantization data in correspondence to the discrimination is subjected to entropy coding. In a different data processor, in order to discriminate a kind of image in a processing block fast and correctly, image data are divided into first processing blocks of m*m pixel matrices and second processing blocks of M*M pixel matrices wherein M>m. For example, m=8 and M=16. A second processing block includes one of first processing blocks and adjacent pixels around it. Image data in a first processing block and image dat in a second processing block including the first processing block are subjected to orthogonal transform to send coefficient data, respectively. It is discriminated according to the coefficient data of the second processing block if the image is a character image, a dot image or a half-tone image to select an appropriate quantization table. Then, image data of the first processing block is quantized according to the selected quantization table and quantized data are coded. In a further data processor, in order to discriminate a dot image in a processing block, two discrimination windows are provided, and a first of the windows consists of coefficient data around the DC component while a second consists of the other data. First, orthogonal transform coefficients of image data in a processing block are calculated, and maximum of absolute values in the two windows are obtained. An image is discriminated to be a dot image if the maximum of the first window is larger than that of the second and the former is larger than a prescribed threshold value.

    摘要： In an image processing apparatus, a color image is read with pixels aligned along a direction to provide first color data on the color image. The first color data includes red, green and blue data at each pixel. A first operator calculates first chroma data according to the first color data. On the other hand, a phase shift device generates second color data by shifting a phase of red data and by shifting a phase of blue data in the first color data, and a second operator calculates second chroma data according to the second color data. A selector selects chroma data having a lower chroma, and a black edge of a character a the color image is discriminated according to the selected chroma data.

    摘要： A rotating shaft section of a rotation cam gear supported on the chassis side and transmitting the driving force of a driving motor can be inserted into and removed from a rotating shaft section of a mode detection switch for detecting a mode from the rotating position of the rotating cam gear. A protruding pointed portion and a groove that are fitted to each other to transmit the rotational force of the rotating cam gear are formed in these rotating shaft sections. Output terminals of the mode detection switch are coupled and attached to the circuit section of a circuit substrate, and the rotating shaft section of the mode detection switch is inserted into the rotating shaft section of the rotating cam gear supported on the chassis side to engage the protruding portion with the groove. This constitution enables easy and smooth insertion and fitting of the rotating shaft sections, thereby improving working efficiency.
