摘要： An apparatus for and a method of detecting a dotted image area in an image. It is judged on the basis of image data corresponding to pixels in a first judging area which includes a predetermined number of pixels including a target pixel whether or not the target pixel is a peculiar point pixel (a peak pixel or a dip pixel). Further, it is judged on the basis of image data corresponding to pixels in a second judging area which is larger than the first judging area whether or not the target pixel is a peculiar point pixel. The dotted image area in the image is detected on the basis of the results of judgment related to the first judging area and the second judging area.

摘要： An image processing controller sets various data necessary for an image forming operation by performing a data communication with an operation unit of an electrographic copying machine. The image processing controller has a pseudo operation task having a function equivalent to the function of the operation unit with respect to data transfer and an image processing control task for performing a handshaking with the pseudo operation task. The pseudo operation task and the image processing control task are constituted by operation programs of a CPU provided in the image processing controller.

摘要： The average value of each of yellow, magenta and cyan color image data of a color-to-be-converted which data are obtained at the time of pre-scanning of a copying machine and stored in memories, respectively, is calculated, and then, predetermined set values are respectively added to and subtracted from the calculated average values of yellow, magenta and cyan to obtain upper and lower limit values of the conversion range. When the lower limit value obtained by subtraction is below a predetermined lower limit restriction value, the lower limit restriction value is set as the lower limit value of the conversion range. With this feature, when an extremely pale color is specified as a color-to-be-converted in a region other than a background portion of a color original where no letters, etc. are printed, the color of the background portion is not converted together with the specified color.

It is judged whether or not the detecting area belongs to a dotted image area on the basis of the number of edge pixels in the detecting area. Consequently, it is possible to detect edges peculiar to the dotted image area on the basis of a leading edge portion or a trailing edge portion of the density, to detect the very small dotted image area on the basis of the number of edge pixels.
