Abstract:
1. An image taking apparatus that forms an image of a subject on an imaging device to create image data representative of the subject, the image taking apparatus comprising: a light-emitting section in which two or more LED's are arranged on a two-dimensional basis, the light-emitting section emitting light to the subject; and a driving section that supplies current to the two or more LED's for luminescence, wherein the driving section causes the two or more LED's to perform light emission in such a way that a relatively small current is supplied to an LED arranged on a center portion, of the two or more LED's, and a relatively large current is supplied to an LED arranged on a peripheral portion, of the two or more LED's, wherein the driving section causes the two or more LED's to perform light emission in such a way that a relatively short time width of pulse current is supplied to an LED arranged on a center portion, of the two or more LED's, so that a relatively small current on a time-means basis is supplied, and a relatively long time width of pulse current is supplied to an LED arranged on a peripheral portion, of the two or more LED's, so that a relatively large current on a time-means basis is supplied, and in addition pulse currents are alternatively supplied to an LED arranged on a center portion and an LED arranged on a peripheral portion, of the two or more LED's.
