Abstract
Abstract A character shaping device includes a tablet or the like upon which characters are written or drawn, and a device for determing distribution functions for the character as projected in the x- and y-directions. From this information the "center of gravity" of the character is calculated, and the x- and y-dimensions of the character are detected to determine the character area. The image is then centered within a normalization area and enlarged or reduced in size according to scale factors dependent upon the relative dimensions of the character area and the normalization area, to obtain a well balanced and sized character which may then be printed along with other characters to form sentences on a printed document or the like.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
130 words
A character shaping device, comprising: an image memory for reading a character in a tablet area and for storing said character as image information in the form of a binary signal for each of a plurality of picture elements; means for determining an x-peripheral distribution function and y-peripheral distribution function of said stored information, respectively; means for determining an area bounding said character and the center of gravity position of said character in respective directions from said x- and y-peripheral distribution functions; means for storing a preset normalization area within said tablet area, and the center position thereof; and means for altering said character bounding area to equate said character bounding area with said normalization area, and center said character within said normalization area, to produce a sized, centered character.
Claim 2
Dependent Claim
130 words
A character shaping device, comprising: an image memory for reading a character in a tablet area and for storing said character as image information in the form of a binary signal for each of a plurality of picture elements; means for determining an x-peripheral distribution function and y-peripheral distribution function of said stored information, respectively; means for determining an area bounding said character and the center of gravity position of said character in respective directions from said x- and y-peripheral distribution functions; means for storing a preset normalization area within said tablet area, and the center position thereof; and means for altering said character bounding area to equate said character bounding area with said normalization area, and center said character within said normalization area, to produce a sized, centered character.
Claim 3
Dependent Claim
134 words
A character shaping device as claimed in claim 1, wherein said plurality of picture elements comprise a matrix of said picture elements arranged in rows and columns and wherein said binary signal for said each picture element has a first value when said each picture element represents a portion of said character and wherein said means for determining an x-peripheral distribution function and y-peripheral distribution function comprises: means for scanning said image information representing each said row of picture elements and for scanning said image information representing each said column of picture elements and for generating said x-peripheral distribution function in accordance with the number of said first value binary signals in each row and generating said y-peripheral distribution function in accordance with the number of said first value binary signals in each column.
Claim 4
Dependent Claim
26 words
A character shaping device as claimed in claim 2, wherein said character stored by said image memory is a handwritten character drawn in said tablet area.
Claim 5
Dependent Claim
23 words
A character shaping device as claimed in claim 3, further comprising means for displaying said sized, centered character for viewing by an operator.
Claim 6
Dependent Claim
63 words
A character shaping device as claimed in claim 1, said means for altering said character bounding area comprising scale up/down means for enlarging/reducing image information in an area between each side of said character bounding area and the center of gravity position thereof so as to make each side of said character bounding area coincide with a corresponding side of said normalization area.
Claim 7
Dependent Claim
55 words
A character shaping device as claimed in claim 5, said scale-up/down means enlarging/reducing said image information according to scale factors obtained by dividing the distance from the center of said normalization area to each side thereof by the distance from said center of gravity position of said character bounding area to a corresponding side thereof.
Claim 8
Dependent Claim
25 words
A character shaping device as claimed in claim 6, wherein said center position of said normalization area may be varied from the geometric center thereof.
Claim 9
Dependent Claim
23 words
A character shaping device as claimed in claim 6, further comprising printing means for printing said sized, centered characters in hard copy form.
