SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND DISPLAY SYSTEM

The present disclosure relates to a signal processing device, a signal processing method, and a display system capable of implementing a multi-display wall system in which display timings are synchronized while suppressing input-output delays.The timing control unit performs control so as to advance start timings of some pieces of processing to be executed on an image signal input for displaying one image by a plurality of display devices, and controls a start timing of first processing on the image signal on the basis of a timing at which second processing executed immediately before the first processing ends in all the display devices. The technology according to the present disclosure can be applied to, for example, a panel constituting a multi-display wall system.
