Abstract
Even in a case in which an image signal that is not normal is included, a display based on a normal image signal is performed. Input signal determination circuits (11A, 11B) replace an abnormal image signal which is determined not to be able to be synchronized by a synchronization circuit (12), among image signals which are included in either a first image signal group or a second image signal group, with an image signal which can be synchronized by the synchronization circuit (12), according to another image signal which is included in either the first image signal group or the second image signal group.
Claims5
An image signal processing device which outputs in parallel image signals that are assigned to respective division display areas obtained by dividing a display area of a display device into multiple pieces and that are synchronized with each other, comprising:
- a synchronization unit which synchronizes the image signals that are assigned to the respective division display areas;
- and
- an image signal determination unit which determines whether or not the image signal which is input to the synchronization unit is an image signal that can be synchronized by the synchronization unit,
- wherein the image signal determination unit receives a first image signal group which includes a set of image signals that is assigned to the respective division display areas, and a second image signal group which includes another set of image signals that is assigned to the respective division display areas, and
- wherein the image signal determination unit replaces an abnormal image signal which is determined not to be able to be synchronized by the synchronization unit, among the image signals which are included in either the first image signal group or the second image signal group, with an image signal which can be synchronized by the synchronization unit, according to an image signal which is included in either the first image signal group or the second image signal group.
