It is also possible to use (β).

That is, if the shortest distance from the additional pixel determination position in the additional pixel to the anti-alias line is β in the additional pixel, the anti-aliasing processing function f (β). Is used to set the color information (C) of the pixel by the following formula.

C = Ca × f (β) + Cp ×
(1-f (β)) Here, Ca is the color of the object and Cp is the color of the background portion.

Further, as another specific example of the additional color information processing, as shown in FIG. 10, in the additional pixel recognized as the additional pixel, the auxiliary anti-alias line is located on the object side. The area of the existing pixel is α (%) of the total area of the pixel, and
When the shortest distance from the additional pixel determination position on the determination auxiliary anti-alias line included in the additional pixel to the anti-alias line is β, the color information (C) of the pixel is a function F of α and β. The color information (C) of the pixel may be set according to (α, β) by the following formula.

C = Ca × F (α, β) + Cp
× (1-F (α, β)) Here, Ca is the color of the object and Cp is the color of the background portion.
