[0130]FIG. 11 is a diagram illustrating an example where the correction table storage area is allocated in a first processing example of this embodiment.

[0131]FIG. 11 shows an example where the entire area of the correction table storage area of the ROM 82 or the RAM 84 as the correction table storage unit 40 is allocated as a correction table storage area common to the R component, the G component, and the B component. That is, the first processing example is an example where the correction table storage unit 40 stores only one type of correction table.

[0132]In the first processing example, the same correction process can be locally or totally carried out on the R component, the G component, and the B component constituting one pixel. Therefore, the correction table in the first processing example can be constructed by correction data corresponding to the amounts of geometric correction.

[0133]In the following description, it is exemplified that the screen SCR is a so-called cylindrica

[0152]FIG. 15 is a diagram illustrating an example where the correction table storage area is allocated in a second processing example of this embodiment.

[0153]In FIG. 15, the correction table storage area of the ROM 82 or the RAM 84 as the correction table storage unit 40 is divided into two areas and is allocated as an R-component correction table storage area and a B-component correction table storage area. That is, in the second processing example, the correction table storage unit 40 stores only two kinds of correction tables.

[0154]In the second processing example, it is possible to correct the pixel shifts of the R component and the B component relative to the display position of the G-component display sub pixel out of the R-component, G-component, and B-component display sub pixels constituting one pixel. Accordingly, the correction table in the second processing example can be constructed by the correction data corresponding to the correction amount of the pixel shift.

[0170]FIG. 18 is a diagram illustrating an example where the correction table storage area is allocated in a third processing example of this embodiment.

[0171]In FIG. 18, the correction table storage area of the ROM 82 or the RAM 84 as the correction table storage unit 40 is divided into three areas and is allocated as an R-component correction table storage area, a G-component correction table storage area, and a B-component correction table storage area. That is, in the third processing example, the correction table storage unit 40 stores three kinds of correction tables.

[0172]In the third processing example, it is possible to independently correct the pixel shifts of the R-component, G-component, and B-component display sub pixels constituting one pixel among the color components. Accordingly, the correction table in the third processing example can be constructed by the correction data corresponding to the geometric correction amount and the correction amount of the pixel shift.
