1. An image display apparatus that displays an image through scanning by a plurality of beam lights, comprising:
- a light source section that supplies the beam lights; and
a scanning section that subjects to scanning the beam lights coming from the light source section, wherein;
the light source section is driven for a tone representation using the beam lights each having a light amount that is assigned a weight depending on how many bits are allocated in a range from minimum to maximum, and allocates at least two of the beam lights to at least one higher-order bit in the range; and
the at least two of the beam lights are allocated a same number of bits.

9. A control method for an image display apparatus that displays an image through scanning by a beam light, comprising:
-
supplying plurally the beam light; and scanning a to-be-exposed area by the beam lights in a first direction, and in a second direction substantially orthogonal to the first direction, wherein; in the supplying, a tone representation is made using the beam lights each having a light amount that is assigned a weight depending on how many bits are allocated in a range from minimum to maximum, and at least two of the beam lights are allocated to at least one higher-order bit in the range; and the at least two of the beam lights are allocated a same number of bits.
