    摘要: The following means are adopted in the image processing apparatus according to the present invention. First, an object image separating means separate a color image described in an outputting control language into the command image generated by the drawing command and the photo image generated by the image data having color information per pixel, such as a bitmap data, so that the command image and the photo image are color-processed separately. As for the command images, there is provided command image processing means to color-process color palette information given to a region specified by the drawing command and to generate a first image having color information by the pixel, such as a bitmap image. As for the photo images, there is provided photo image processing means to color-process and generate a second pixel image. In this color-processing, the photo image is divided into a plurality of image blocks. Then at least one kind of colors or representative colors among the colors making up the image block is decided on.

    摘要: The invention relates to the image processing, and more particularly to the image processing method, the image processing apparatus, and the image processing system that compress color data. In order to extract the representative color from a small region on the color image in order to approximate to the color image, the invention performs the calculating of an average and a variance of color data of the small region, the color of which the variance is the largest is determined as a target color. According to the average of the target color, the small region is divided into two sections. After calculating the region information of the two sections and each representative color of section, judging whether the obtained number of representative colors is more than the requested number of colors, if the obtained number is more than the required number of colors, the dividing is completed. If not, the dividing is repeated again.

    摘要: An inexpensive image reading apparatus which does not need a delay buffer and which permits image inputting with an image sensor array with reduced color dislocation on character edge etc. Color images are inputted in this process: Line reading circuit 102 reads three color data simultaneously. On the basis of the top and end points of a line of green data obtained by encoders and scanned position detection circuit, offset size deriving circuit 107 works out the top and end scanned positions for the data on the other colors, that is, red and blue. From the top to the end scanned positions for the respective colors, the mapping coordinates deriving circuit 108 works out the coordinates of the picture elements for the read color data. Mapping circuit 109 maps the respective color data on the image memory 110 at the positions corresponding to the coordinates obtained by the mapping coordinates deriving circuit 108.

    摘要: Luminance data Y(1) (i=1,2, - - - ,n, - - - ) are input one by one to a detecting unit, and luminance correlation information R(i-1,i) denoting a luminance correlation or a luminance non-correlation between the luminance data Y(i) and Y(i-1) are generated. Four pieces of luminance correlation information R(n-1,n) to R(n+2,n+3) are stored in a filter controlling unit. Also, chrominance data C(i) are input one by one to a starting-stage chrominance data generating unit, and starting-stage chrominance data C1(n+2) is generated from the chrominance data C(n+1), C(n+2) and C(n+3) according to the luminance correlation information R(n+1,n+2) and R(n+2,n+3). other starting-stage chrominance data C1(n) and C(n+1) are generated in advance in the same manner. Second-stage chrominance data C2(n+1) is generated from the starting-stage chrominance data C(n), C(n+1) and C(n+2) in a second-stage chrominance data generating unit according to the luminance correlation information R(n,n+1) and R(n+1,n+2). Also, other second-stage chrominance data C2(n-1) and C2(n) are generated in advance in the same manner. Smoothed chrominance data C3(n) is generated from the second-stage chrominance data C(n-1), C(n) and C(n+1) in a final-stage chrominance data generating unit according to the luminance correlation information R(n-1,n) and R(n,n+1). Therefore, each of smoothed chrominance data C3(i) can be generated with a limited number of memories at a high speed.

    摘要: Each copy elements of data being an object to be monitored such as printing data or reading data including at least one kind of copy elements is monitored according to at least one kind of copy inhibition information stored in inhibition information storage means and capable of being updated. By the monitoring, when one of the copy elements is judged to agree with the kind of coy inhibition information, input or output of the data being monitored is inhibited. Secrecy management information is given to the copy inhibition information, and a secrecy management level of a user is assigned to each user. In such a way, when the secrecy management level is higher than that of secrecy management information, the inhibition of the input or output is canceled. An ID for tracing a device which has copied a printed matter is given to the copied printed matter so as to prevent unauthorized copies form diffusing.
