■ Text
● Specifies a font type for each character string
● Supports variable-width fonts such as proportional fonts
● Scaling function
● Supports anti aliasing font
■ Line drawing
● Direct drawing by specification of start/end point coordinates (pattern data is not needed)
● Configurable line display up to 510 lines/field

● Contrast, brightness, color saturation and hue adjustment function
● Color killer function, video input detection function
■ Video Picture Input Display Function
● Scaling function (a function to adjust the resolution of the input image to the display resolution, not a
zooming function)
● Mirror inversion function (only horizontal direction)
Others
■ CPU interface
