Abstract
Abstract An anti-shake camera measures a shaking movement of the camera around at least a first dimension and around a second dimension (e.g., X and Y dimensions). Based on these measured camera shake values, the anti-shake camera generates a forecasted camera shake value for each measured dimension of motion. When both of these forecasted camera shake values achieves a predetermined level, such as zero, within a predetermined time, the anti-shake camera begins an exposure operation.
