摘要： PROBLEM TO BE SOLVED: To decrease a time required to generate correction data used for correcting jaggy of an outline of bit map data and a time required to set data when actually in use. SOLUTION: The picture data processing unit is provided with a window 73 that extracts data of each dot in a prescribed area around an object dot of bit map data and with a pattern recognition section 74 that recognizes a shape of line segments at a border of a black dot area and a white dot area in the extracted image data and generates code information in pluralities of bits denoting characteristics of the shape of line segments. A slope bit limiting means 78 provides an output of a SLOP signal (a bit denoting whether a line segment is upward or downward slant to the right) received from the pattern recognition section 74 to a memory block 75 without any modification when a NO-MATCH signal is at a low level (in the case that a target pixel requires correction of picture), but provides an output of the SLOP signal received from the pattern recognition section 74 to the memory block 75 after fixing the SLOP signal to a low level output when the NO-MATCH signal is at a high level (in the case that a target pixel requires no correction of picture). The memory block 75 provides an output of prescribed correction data when the SLOP signal is valid.

摘要： PROBLEM TO BE SOLVED: To provide an image data processing unit that reduces time for generating correction data used for jaggy correction and minimizes a data setting time in actual use of the processing unit. SOLUTION: An image data processor is provided with a pattern recognition means 74 that recognizes a linear shape of a border part between a black dot area and a white dot area of image data and generates code information in a plurality of bits representing a characteristic of the recognized linear shape of object dots, a discrimination means that discriminates whether or not the dots require correction, and a memory block 75 that reads and outputs correction data stored in advance by using the code information for the address of the dots discriminated to require correction. Furthermore, the image data processing unit is provided also with an inclination bit changeover means that sets a bit denoting the inclination of a line segment to be valid or invalid as to whether the inclination rises upward to the right or decreases downward to the right among a plurality of bits representing a characteristic of the shape of the line segment recognized by each dot.

摘要： PROBLEM TO BE SOLVED: To improve picture quality by performing the interpolation of image data for respective required dots in spite of the presence/absence of jaggy contour line around them. SOLUTION: Concerning an image data processor 7, the form of line segment at the section of boundary between the black dot area and white dot area of image data extended into the form of bit map is recognized, the feature of the line segment form recognized for the respective required dots is replaced with the code information of plural bits and while utilizing one part of that code information at least, the dot discriminated to be corrected is corrected corresponding to this code information. In such a case, this processor is provided with a 1st correcting means 11 for performing the correction corresponding to the replaced code information of plural bits to the bit discriminated to be corrected and a 2nd correcting means 10 for recognizing the feature of image data extended into the arbitrary form of bit map and similarly performing the correction to the other bits corresponding to the other code information of combination excepting for the code information of the 1st correcting means.

摘要： PROBLEM TO BE SOLVED: To reduce tonner consuming quantity without losing the shape of a image in image data which is extended in a bit map state as much as possible and also to attain efficiency in generating picture correcting data. SOLUTION: A main-scanning counting means 78 counting the number of dots in the main scanning direction of picture data which is extended in the bit map state and a sub-scanning counting means 79 counting the number of lines in the sub-scanning direction of image data are provided. When the dot is discriminated not to require correction and also to be the black dot which is surrounded by the black dots, a part of code information is replaced to the count value of plural bits which are outputted from the main-scanning counting means 78 and the sub-scanning counting means 79 and correction data is read from a memory block 75 as an addree concerning the code information.

SOLUTION: The processing unit is provided with a main scanning count section 510 counting the number of dots in the main scanning direction of image data expanded in a bit map. Then when a discrimination means (not shown) discriminates it that no correction is required and dots discriminated to be undesired dots are code information in plural bits denoting black dots which are surrounded by other black dots, the code information in plural bits other than part of the code information being the result of discrimination of whether or not dots require correction by the discrimination means is replaced with main scanning count in plural bits outputted from the main scanning count section 510 and correction data are read from a memory block 505 by using the code information as an address and outputted.

摘要： PURPOSE:To imporve the picture quality of the image data and also to further decrease the quantity of data needed for higher image resolution and also needed to be previously stored in a memory. CONSTITUTION:The segment shape of a boundary part between the black and white dot areas of the image data evolved in a bit map form is recognized by a pattern recognizing part 74, and the features of the recognized segment shape are replaced with the bit code information to each necessary dot. The correction data are sent from a memory block 75 by means of the bit code information, and the images are corrected. At the same time, the same image data evolved in a bit map form with the same timing are repetitively generated in an FIFO memory 77 against an optional signal waveform. Thus the N-fold size (equivalent to the generating frequency) and the N-fold image resolution are secured for the image data.
