For example, the input data is selected and output according to the display priority order in which the display priority orders of the pattern graphic data and the gradation data are reversed. In this case, the display priority order is gradation data> pattern graphic data> border color data.

Further, the selection circuit 14 selects and outputs the input data according to the normal display priority order when the window signal is not input, that is, for the display position outside the window. . In this case, the display priority order is pattern graphic data> gradation data> border color data.

Even in this case, the gradation on / off control signal is input to the selection circuit 14, and when the gradation on control signal is input, the border color data is not selected regardless of the presence or absence of the window signal. When the gradation off control signal is input, the gradation data may not be selected regardless of the presence or absence of the window signal.

In each of the above-described embodiments, the gradation generating unit 11 has R indicating the start color of the gradation.
GB data, a unit width for changing the color tone, and a color tone change rate for each unit width are set. Instead of setting the unit width, the number of steps shown in FIG. 3 may be set, and the unit width may be calculated by dividing the width of the gradation surface or the window width by the number of steps. Instead of setting the color tone change rate for each unit width, the number of steps and the gradation end color shown in FIG. 3 are set, and the color tone change rate for each unit width is calculated from the number of steps and the gradation end color. You may do it.

Further, gradation data whose color tone changes horizontally or vertically may be generated, or gradation data whose color tone changes obliquely may be generated. Gradation data whose color tone changes in an oblique direction can be obtained based on the set value in the horizontal direction by setting the gradation control data in each of the horizontal and vertical directions (however, the starting color is the same data). It is generated by sequentially multiplying the gradation data obtained and the gradation data obtained based on the set value in the vertical direction.

When performing gradation display on the entire screen, the gradation display may be performed on the border surface without providing the gradation surface.

According to the above embodiment, when the gradation display is realized, it is not necessary to prepare the pattern graphic data for each unit width for changing the color tone, so that the CG-RO storing the pattern graphic data is used.
M capacity can be saved.
