Abstract: An image processing device according to the present disclosure includes: an input section that receives an input image signal including an input synchronization signal and input image data; a first processor that performs first processing on the basis of the input image data at a timing corresponding to the input synchronization signal; a synchronization signal generator that generates an output synchronization signal; a second processor that performs second processing on the basis of a processing result of the first processing at a timing corresponding to the input synchronization signal or a timing corresponding to the output synchronization signal; a controller that controls at which timing of the timing corresponding to the input synchronization signal and the timing corresponding to the output synchronization signal the second processor is to perform the second processing; a third processor that performs third processing on the basis of a processing result of the second processing at a timing correspondi
