LIGHT EMISSION CONTROL SYSTEM, LIGHT EMISSION SYSTEM, LIGHT EMISSION CONTROL DEVICE, AND LIGHT EMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/106344
Kind Code:
A1
Abstract:
A first light emission control device (10A) generates a clock signal and starts executing a first drive sequence in which a state of each of light-emitting elements in a first light-emitting element group (20A) is sequentially switched in synchronization with the clock signal, and then changes a property of the clock signal from a first property to a second property at a specific timing. After the change, a second light emission control device (10B) executes a second drive sequence in which a state of each of light-emitting elements in a second light-emitting element group (20B) is sequentially switched in synchronization with the clock signal.
