Abstract

A pixel display device includes a decoding unit for decoding an image signal, a first storage unit for storing the image signal decoded, a second storage unit for storing the image signal whose aspect ratio has been converted, and a control unit. The control unit initializes the second storage unit by storing image data having a predetermined color tone therein, and divides the image signal stored in the first storage unit into a predetermined number of regions corresponding to the number of display pixels of a display screen. The control unit subjects the image signal stored in the first storage unit to an enlarging process, based on horizontal/vertical magnification information indicating the different magnification factors of the different divided regions in at least one of the horizontal and vertical directions, and stores the image signal subjected to the enlarging process in the corresponding regions of the second storage unit.

Dependent claims

A pixel display device for displaying an image signal after converting an aspect ratio thereof, comprising,

a decoding unit for decoding the image signal;
a first storage unit for storing the image signal decoded;
a second storage unit for storing the image signal whose aspect ratio has been converted;
and
a control unit for initializing the second storage unit by storing image data having a predetermined color tone therein;
dividing the image signal stored in the first storage unit into a predetermined number of regions, the predetermined number corresponding to the number of display pixels of a display screen;
subjecting the image signal stored in the first storage unit to an enlarging process from region to region, based on horizontal/vertical magnification information indicating different magnification factors of different divided regions in at least one of horizontal and vertical directions;
and
storing the image signal subjected to the enlarging process from region to region in corresponding regions of the second storage unit.
