Abstract
An image pickup apparatus capable of detecting a motion vector and selecting a vector search method which enables effects to be always obtained in various usages of a camera, taking into account load balancing with the performance. One input image is set as a reference image, and the other input image is set as a search target image. Using a template having a predetermined size on the reference image, a motion vector is detected from the search target image. A determination index associated with frequency of occurrence of parallax conflict is calculated. When the determination index is not larger than a threshold value, a first detection method using a single layer is selected, whereas when the determination index is larger than the threshold value, a second detection method using a plurality of layers is selected.
