ABSTRACT:
An image producing apparatus includes at least one light emitting diode stimulating ray source, a filter for cutting a stimulating ray emitted from the at least one light emitting diode stimulating ray source and allowing only fluorescent light generated by stimulation of a fluorescent substance by the stimulating ray to pass therethrough, and a solid state image sensor for detecting the fluorescent light transmitted through the filter. According to the thus constituted image producing apparatus, it is possible to safely produce a fluorescent image at low cost.
