ABSTRACT:
A display device performs sampling of an input image signal for displaying by a dot matrix display element, and includes a selection unit for, in consonance with types of information to be displayed, selecting either to supply a predetermined pixel group with a signal that is obtained by sampling at a first timing, or to supply the predetermined pixel group with a signal that is obtained by sampling at a second, different timing. In addition, the display device, which performs sampling of input image signals and displays the resultant signal by using a dot matrix display element, includes a detection circuit for detecting character information that is included in the input image signal, and a unit for altering a method for processing the input image signal in consonance with an output of the detection circuit.
