Abstract
A display control apparatus, allowing a plurality of input operations to be performed by a touch panel, increasing application performance, and decreasing power consumption, is realized. The display control apparatus performs a coordinate sampling processing at a short (fast) coordinate sampling cycle t1 until a predetermined time T elapses from the starting of touch, and performs the sampling in a coordinate sampling cycle t2 that is longer (slower) than t1 after the predetermined time T elapses. The display control apparatus can certainly distinguish an operation in a coordinate sampling cycle of a necessary minimum speed by setting a coordinate sampling cycle to be high-speed at immediately after starting, and changing a coordinate sampling cycle to be low-speed in the other period.
