ABSTRACT:
In an image-taking apparatus, a main CPU reads a sensitivity level that has been set, thereby determining whether a subject distance measured in AF processing is longer as compared to a threshold. The threshold is variable such that the higher the sensitivity level is the longer the threshold is. When the main CPU determines that the subject distance is longer as compared to the threshold, a metering/distance-measuring CPU causes a first light emitter having a xenon tube to emit light in response to an instruction from the main CPU. When the main CPU determines that the subject distance is shorter as compared to the threshold, the metering/distance-measuring CPU causes a second light emitter having an LED to emit light in response to an instruction from the main CPU.
