IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD

摘要

A light quantity measurement unit measures a quantity of light of a light source having a first light emitting element which outputs light of a first wavelength band and a second light emitting element which outputs light of a second wavelength band. The light quantity measurement unit comprises first and second filters with the first and second wavelength bands being detection wavelength bands. On the basis of results of each measurement of the quantity of light which is measured via the first and second filters when the first and second light emitting elements are made to emit light sequentially, a control unit generates first correction information with the second wavelength band light being measured with the first filter and second correction information with the first wavelength light being measured with the second filter, removes a quantity of light based on the first correction information from the quantity of light measured via the first filter to derive a first correction light quantity of the first light emitting element, removes a quantity of light based on the second correction information from the quantity of light which is measured via the second filter to derive a second correction light quantity of the second light emitting element, and controls the quantities of light of the first and second light emitting elements on the basis of the first and second correction light quantities.
