An image processing apparatus that operates in a first power state or a second power state in which power consumption is smaller than in the first power state includes a detection unit that includes regions in which an object is detected, an analysis unit configured to analyze results of detection obtained in the plurality of regions, wherein the analysis unit enters a power saving mode in the second power state, a control unit that causes the analysis unit to return from the power saving state in a case where an object has been detected in any of the plurality of regions included in the detection unit in the second power state, and a power control unit that, in a case where the analysis unit determines that an object has approached the image processing apparatus, shifts the image processing apparatus from the second power state to the first power state.
