Imaging apparatus and HDRI method
View Patent ↗An imaging apparatus includes an image sensor and a processor that merges together a plurality of images captured by said image sensor to produce a composite image. The positions or the plurality of images being adjusted to reduce displacement of a reference area that is determined within each one of said plurality of images before the plurality of images is merged together. The reference area includes at least one of an in-focus area determined by a focusing operation, a face area determined by face-sensing processes, a predetermined-color area determined by white-balance information and predetermined color information, and a predetermined-brightness area determined by photometry.
1. An imaging apparatus, comprising:
an image sensor; and
a processor that merges together a plurality of images captured by said image sensor to produce a composite image;
the positions of the plurality of images being adjusted to reduce displacement of a reference area that is determined within each one of the plurality of images before the plurality of images is merged together; and
the reference area including at least one of an in-focus area determined by a focusing operation, a face area determined by face-sensing processes, a predetermined-color area determined by white-balance information and predetermined color information, and a predetermined-brightness area determined by photometry,
wherein the reference area is alternatively selected in a sequential order of the in-focus area, the face area, the predetermined-color area, and the predetermined-brightness area, such that a subsequent area within the order is selected only after the position adjustment using current area within the order is determined to be inappropriate.
2. An imaging apparatus comprising:
an image sensor; and
a processor that merges together a plurality of images captured by said image sensor to produce a composite image;
the positions of the plurality of images being adjusted to reduce displacement of a reference area that is determined within each one of the plurality of images before the plurality of images is merged together; and
the reference area including at least one of an in-focus area determined by a focusing operation, a face area determined by face-sensing processes, a predetermined-color area determined by white-balance information and predetermined color information, and a predetermined-brightness area determined by photometry,
wherein the reference area is defined by a combination of at least two of the in-focus area, the face area, the predetermined-color area, and the predetermined-brightness area,
wherein the in-focus area, the face area, the predetermined-color area, and the predetermined-brightness area are respectively weighted, and the reference area is defined with reference to a total weight of a combination area comprising the combination of at least two of the in-focus area, the face area, the predetermined-color area, and the predetermined-brig area.
3. An HDRI method, comprising:
merging a plurality of images captured by an image sensor to produce a composite image;
the positions of the plurality of images being adjusted to reduce displacement of a reference area that is determined within each one of the plurality of images before the plurality of images is merged together; and
the reference area including at least one of an in-focus area determined by a focusing operation, a face area determined by face-sensing processes, a predetermined-color area determined by white-balance information and predetermined color information, and a predetermined-brightness area determined by photometry,
wherein the reference area is alternatively selected in a sequential order of the in-focus area, the face area, the predetermined-color area, and the predetermined-brightness area, such that a subsequent area within the order is selected only after the position adjustment using a current area within the order is determined to be inappropriate.
