Image displaying and controlling apparatus and method

An image displaying and controlling method for formatting a first image having a first aspect ratio for display as a second image having a second aspect ratio, said method comprising the steps of:

• storing pixel data of said first image on a unit of a horizontal line basis;
• converting a line number comprising one display image of said first image so as to format said first image in said second aspect ratio by combining pixel data of at least two lines stored in said storing step in accordance with a programmable weighting factor;
• and
• adjusting the vertical synchronization of a frame of the first image to be converted in said converting step, such that a start of the vertical synchronization of a frame of the first image is earlier than a start of the vertical synchronization of a frame of the second image.

An image displaying and controlling apparatus for formatting a first image having a first aspect ratio for display as a second image having a second aspect ratio, said apparatus comprising:

• memory configured to store pixel data of said first image on a unit of a horizontal line basis;
• a line number converter configured to convert a line number of said first image so as to format said first in said second aspect ratio by combining pixel data of at least two lines stored in said memory in accordance with a programmable weighting factor;
• and
• a timing controller configured to adjust the vertical synchronization of a frame of the first input to the line number converter, such that a start of the vertical synchronization of a frame of the first image is earlier than a start of the vertical synchronization of a frame of the second image.
