Referring to FIG. 8, the controller 180 displays the memo screen on the touch screen 151 based on the user control input received through the user input unit 130 (S301).

When the background image is set on the memo screen, the control unit 180 calculates a recommended color for memo display based on the color information of the background image (S302).

In addition, the memo inputted through the memo screen is displayed using the recommended color calculated in step S302 (S303).

In step S302, the control unit 180 divides the memo screen into at least one area, and calculates an intermediate color representing each area based on the color information of each pixel. Here, the color information of each pixel includes RGB, saturation, brightness, etc., and an intermediate color can be calculated through an average calculation on the pixel values. That is, the average color of each region can be calculated through an average calculation of the pixels included in each region.

As described above, when the intermediate color is calculated for each area, the control unit 180 can calculate at least one recommended color based on the calculated intermediate color. For example, at least one color set to the calculated intermediate color and the matching color, and at least one color having a complementary color relationship with the calculated intermediate color may be selected as the recommended color.

On the other hand, in step S302, the control unit 180 can distinguish the memo screen from the area where the memo is displayed and the area where the memo is not displayed. In this case, the control unit 180 may calculate the intermediate color for the area where the memo is displayed, and calculate the recommended color for color correction of the currently displayed memo based on the calculated intermediate color.

Also, in step S302, the control unit 180 may divide the memo screen into a plurality of areas based on the background image. For example, the control unit 180 may divide the area where different objects are displayed into different areas, based on the display position of each object included in the background image. In addition, for example, the controller 180 may divide the memo screen into a plurality of areas by grouping pixels having a color variation within a predetermined range in the background image into one area. In addition, for example, the control unit 180 may divide the memo screen into a plurality of areas by grouping pixels having hues included in the same category into one area. On the other hand, when the memo screen is divided into a plurality of areas, the controller 180 may calculate the middle color for each area and calculate a recommended color for each area based on the calculated middle color for each area. In this case, the memo inputted through the memo screen may be displayed in different colors depending on which area the display position is included in. Further, when a memo is displayed over a plurality of regions to which different recommended colors are associated, a plurality of colors may be used to display the memo.

In addition, in step S302, the control unit 180 may set the entire memo screen as one area. In this case, the control unit 180 may calculate the intermediate color for the entire memo screen, and may calculate the recommended color for the entire memo screen using the calculated intermediate color.
