Abstract: An endoscope apparatus according to a present embodiment has a CCD and an LED control section which controls LED1 and LED2. The LED control section sequentially drives the two LEDs, LED1 and LED2, on the basis of an image pickup start timing signal corresponding to each image pickup cycle S for the CCD within the image pickup cycle S such that driving time periods for LED1 and LED2 do not overlap. The LED control section also variably controls the driving time periods for LED1 and LED2 to adjust an amount of exposure within the image pickup cycle S and performs control so as to conduct, within the image pickup cycle S, at least a first drive within the image pickup cycle S of LED2 that is a second or subsequent one to be driven with reference to a timing for driving of LED1 that is driven earlier.
