摘要： Disclosed is an image data processor for processing input image data representing the gray level of each of pixels constituting an image to produce output image data representing the gray level of each of pixels constituting an output image. The relative position of the pixel corresponding to the input image data in a group of pixels including a predetermined number of pixels is identified. The input image data is subjected to data processing corresponding to the relative position of the pixel in the group of pixels on the basis of the result of the identification. Consequently, gray levels are represented by the entire group of pixels.

摘要： In a gradation output adjusting method according to the present invention, a gradation correcting section 64 corrects a gradation value of input data in accordance with a predetermined gradation correcting curve and applies the data after the correction to a printer output section 66. In preparing a gradation correcting curve, test data for forming a gradation scale is inputted to the printer output section 66 from a CPU 70. An image corresponding to the test data is read by a scanner section 1. A proper gradation value to be applied to the printer output section 66 is found with respect to some gradation values of the input data on the basis of the result of the reading. A pre-gradation correcting curve is prepared on the basis of the proper gradation value. The pre-gradation correcting curve and a plurality of types of curve patterns previously stored in a ROM 72 are matched. A curve pattern which is best matched to the pre-gradation correcting curve is set as a detailed gradation correcting curve. Since the pre-gradation correcting curve and the curve pattern are matched to set the gradation correcting curve, therefore, the amount of operation may be small and processing time is reduced.

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.

摘要： An apparatus for and a method of judging a dotted image area using a small-capacity memory. Image data corresponding to one line out of image data representing an original image are stored in a line memory. On the line corresponding to the image data stored in the line memory, a target pixel is successively set along the main scanning direction. Image data corresponding to the target pixel is compared with image data corresponding to pixels around the target pixel. It is judged whether or not the target pixel is a peculiar point pixel on the basis of the result of the comparison. Further, the distance between peculiar point pixels is operated. The operated distance between the peculiar point pixels is referred to a predetermined judgment basis, to judge whether or not a judging area including the finite number of pixels is a dotted image area.
