There is provided an image discriminating apparatus for discriminating the type of an image accurately. The apparatus compares a maximum value R among absolute values of mutual differential values of three color components of each pixel composing an image, with two predefined threshold values &bgr; and &ggr;, respectively, and counts numbers C1-C3 of the monochrome pixels, medium pixels and color pixels, respectively, on the basis of the comparison result for each line within the image. The apparatus judges each line within the image as a color line when C3&plus;C2&times;&ohgr;>&thgr;, as a monochrome line when Cl>&ngr;, and judges the image as a color image when a number of color lines in the whole image exceeds a threshold value. The second apparatus compares maximum and minimum values of the absolute values of each pixel with three threshold values to judge whether each pixel is a color, medium, ground or monochrome pixel and increments counter values of color, medium and monochrome pixel counters according to the range of each discriminated pixel. When the number of continuous monochrome pixels exceeds a threshold value within the image, the apparatus corrects the three counters and discriminates the type of the image based on the three counters after the correction.

Input data corresponding to three primary colors C, M and Y are subjected to masking correction, to obtain data C', M' and Y'. A correction factor in a masking equation is varied depending on which of three sections into which all the gray levels of each of the input data C, M and Y are divided, the section being a section to which the input data of a selected color belong. As a result, suitable masking correction conforming to the value of the input data is made, thereby to improve color reproducibility of a color image.

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.

Disclosed is an apparatus for detecting pixels in a dotted image area (dotted area pixels). Image data corresponding to each of the pixels is coded into one of a predetermined number of discrete values. The distance between change points at which the value of the pixel after the coding is changed from a first value to a second value is detected. Further, it is examined whether or not periodicity is recognized in the distance between the change points in the vicinity of a target pixel. If periodicity is recognized in the distance between the change points, it is judged that the target pixel may constitute a dotted image area.
