Abstract: An endoscope apparatus includes: a first semiconductor light-emitting element; a light source drive section; a first detection section; a storage section configured to store a threshold value indicating whether or not the first detection section can correctly detect an intensity; and a control section configured to, if the intensity detected by the first detection section exceeds the threshold value stored in the storage section, control the current value of the drive signal based on the intensity detected by the first detection section, for the light source drive section, and if the intensity detected by the first detection section does not exceed the threshold value, perform control so as to make the current value of the drive signal constant to provide pulsed light emission and change a duty cycle or a number of pulses to perform light adjustment, for the light source drive section.

Abstract: A light source apparatus includes: a light source; a light source driving section; a light detection section; a temperature detection section; and a control section being configured to, when determining that detected brightness is outside a range of brightness set for detecting abnormality in the light source or the light detection section and detected temperature is within a range of temperature set for detecting the abnormality in the light source or the light detection section, cause the light source driving section to perform driving of the light source for a case of abnormality in the light detection section, and when determining that the detected brightness is outside the range of brightness and the detected temperature is outside the range of temperature, cause the light source driving section to perform driving of the light source for a case of abnormality in the light source.
