Abstract

PURPOSE:To eliminate a need of rescanning to improve the operability by subjecting picture data, which is developed in a picture memory means for conversion, to the picture processing based on an indicated parameter and transferring this data to a picture memory means for display. CONSTITUTION:When a picture image is read from a picture input part 4a, this image is converted to multilevel data by a picture data control part 4c. When the filter processing is designated in a preliminarily set input condition, the control part 4c performs the filter processing like edge emphasis or screen elimination. When the change of the magnification is designated, the magnification is changed. When binarization is indicated in the input condition and a threshold level is set, picture data is binarized. When the processing is terminated, the control part 4c transfers picture data held in a picture memory part 4b for conversion to a picture memory part 3b for display, and a processor part 3a displays transferred picture data on a display device 5.

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image processing device that performs various image processing on image data input from an image input means such as a scanner. In this image processing apparatus, one image is manually processed based on parameters set at the time of input. For example, if you set a threshold level (threshold value for white or black when performing binarization) during input, the image will be read at the set threshold level and converted to binary image data. Ru.

[Problem to be solved by the invention] Conventionally, all images input from a scanner were binarized, so once binary data was sent from the scanner, it was difficult to change the threshold level or change the dither pattern. It is not possible to perform various modification processes such as specifying the image, changing the reading area, or emphasizing edges. Therefore, the user must reset the various parameters and input the image again, making the operation difficult. There was a problem that it became complicated. Particularly, when scanning is performed many times to obtain a desired image, a lot of time and effort are required.
