Abstract:
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 means for storing pixel data of said first image on a unit of horizontal line basis;line number converter means for converting 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 memory means in accordance with a programmable weighting factor; andtiming controller means for controlling storing operation timing of said memory means so that said first image is not broken down in converting process by said line number converter means,wherein said timing controller means controls the storing operation on a unit of horizontal line basis so that the line form of pixel data read from said memory means is to be a line format of an interlace scanning system, andwherein said first image comprises 480 lines on a noninterlace scanning system;said second image comprises 480 lines on the interlace scanning system;said memory means stores pixel data for two lines;said line number converter means converts 480 lines to 432 lines by processing said pixel data for two lines; andsaid timing controller means controls starting timing for said first image so as to be 14 lines earlier than the starting timing of said second image.
