Display control device and display control method

A display control method for controlling display of a frame image on a display portion which displays the frame image, the frame image including an input image based on an input image signal and an OSD image for on-screen display, the display control method comprising:

• a first step of determining a frame rate in displaying the frame image on the display portion as a determined frame rate;
• and
• a second step of converting a present frame rate into the determined frame rate when the determined frame rate is different from the present frame rate,
• wherein the first step includes:
• an acquiring step of acquiring information about the OSD image;
• and
• a determining step of determining whether the determined frame rate is set to a frame rate identical to the present frame rate or a frame rate higher than the present frame rate, based on the acquired information about the OSD image,
• and wherein in the first step, when it is determined in the determining step that the determined frame rate is set to the frame rate higher than the present frame rate, the frame rate is determined as the determined frame rate to display the frame image on the display portion at the determined frame rate starting from a frame image which is K frames after a frame image currently displayed on the display portion, where K is an integer not less than 1 and not more than 10.
