Abstract
A light emitting chip includes: a first data storage unit configured to store data for causing a first light emitting unit to emit light; a second data storage unit configured to store data for causing a second light emitting unit to emit light; a signal output unit configured to output a first trigger signal and a second trigger signal delayed with respect to the first trigger signal; and a drive unit configured to drive the first light emitting unit, in a case where the first trigger signal is output, based on data stored in the first data storage unit, and drive the second light emitting unit, in a case where the second trigger signal is output, based on data stored in the second data storage unit.
