pixels have been added along some portions of the vertical line in fig4 the intensity of these additional pixels is approximately half of that of the original pixels the legend on the side shows that the original line has the color intensity value of 15 while the background has the color intensity value of zero the compensating line has the color intensity value of 7 5 although the enhanced character has not changed its overall height it has gained a better proportion between the vertical and horizontal lines as a result the enhanced character appears aesthetically more acceptable such effect is more readily appreciated in some characters or numbers that have a sharp contrast between the vertical and horizontal line components on the other hand other characters such as 34 34 underscore and 34 34 hyphen are not affected by the preferred embodiment of the invention referring now to fig5 a and 5b similarly horizontally isolated single pixels as shown in fig5 a are enhanced by the above described preferred embodiment of the invention fig5 b shows the enhanced horizontally isolated single pixels the legend on the side shows that the original pixels have the color intensity value of 15 while the background has the color intensity value of zero the compensating pixels have the color intensity value of 7 5 these horizontally isolated single pixels are not visually distorted as much as the vertical single pixel line because there is no comparison such as the case between the vertical and horizontal line there is less need for correcting the.
