Classification: CPC H | IPC H

Claim 0:
1. A light emission control apparatus, comprising:
a light emitting element configured to emit pulsed light, wherein the light emitting element comprises:
a first light emitting element and a second light emitting element that are configured to output light in wavelength regions different from each other and emit light at timings different from each other; and

an overcurrent determination circuit comprising:
a first overcurrent determination circuit corresponding to the first light emitting element and a second overcurrent determination circuit corresponding to the second light emitting element,

wherein each overcurrent determination circuit comprises:
a sample-and-hold circuit configured to obtain a driving current value of the light emitting element in accordance with a timing of a light emitting interval of the light emitting element that emits the pulsed light, and
a comparator circuit configured to compare the obtained driving current value with a value of a predetermined determination level and determine whether overcurrent has flowed in the light emitting element.
