PROBLEM TO BE SOLVED: To provide electronic equipment having a projection function, the equipment suppressing a decrease in the brightness of a projection image even if power supplied to a light source is decreased in order to reduce power consumption. SOLUTION: The electronic equipment having a projection function includes: a projecting unit 200 that projects a projection image by using light generated by the LED light source 223; a light-source power supply control section 101A that controls power supplied to the LED light source 223; and a projection image size control section 101B that controls the size of a projection image projected by the projecting unit 200; a battery remaining capacity estimating circuit 323 that detects a remaining capacity of a battery 321 that supplies power. On the basis of the remaining capacity of the battery 321, the light-source power supply control section 101A alters power supplied to the LED light source 223. On the basis of power supplied to the LED light source 223, the projection image size control section 101B alters the size of a projection image. COPYRIGHT: (C)2009,JPO&INPIT
