Claim of US Patent No. 9,479,692

1. An image processing apparatus comprising:
a processor; and
a memory including instructions that, when executed by the processor, cause the processor to:
acquire images that are successively captured with an image sensor;
perform a face detection process on the acquired images;
determine, in a case where a plurality of faces are detected in an image, a main face from the plurality of faces;
detect a region including at least a part of the main face in the acquired images; and
wherein the instructions further cause the processor not to detect the region until the number of images, in which the main
face is detected, among a predetermined plural number of images is not less than a threshold value,

wherein the instructions further cause the processor to start detecting the region in a case where the number of images, in
which the main face is detected, among the predetermined plural number of images is not less than a first threshold value
and, (i) a movement amount of the main face is less than a second threshold value and/or (ii) a variation amount in size of
the main face is less than a third threshold value.
