Abstract
Image display apparatus and method with an LED matrix device. Each dot of the device is composed of one red LED, one blue LED and two green LEDs. When data displayed in a 16.times.16 dot matrix is displayed by reducing the data to a 8.times.8 dot matrix, 2.times.2 dots of the 16.times.16 matrix are grouped into one unit composed of 2.times.2 dots arrayed in a matrix. Four data, i.e., data obtained by extracting upper-left data from all the units, data obtained by extracting upper-right data, data obtained by extracting lower-left data, data obtained by extracting lower-right data, respectively, from all the dot units, are successively displayed on a time division basis with deviation corresponding to a half dot relative to one another. Image of smooth contour can be generated even with a small-scale LED display apparatus having a small number of dots and low resolution.
