US 7787022 B2Abstract
(ii) a separate sensor for acquiring a low resolution image including a subsample resolution representation of the main image; and
(c) a red-eye filter for correcting a red eye defect within the main image acquired by the main image sensor based on analysis of the low resolution image acquired by the separate sensor including the subsample resolution representation of the main image
(d) a dedicated hardware subsystem which is provided low resolution image data directly from the separate sensor; and
(f) wherein the main system memory is configured to receive meta data that comprises identified red areas determined not to be red eye regions.
2. The camera of claim 1, further comprising a module for changing a degree of subsampling.
7. The camera of claim 1, wherein said subsample resolution representation is determined using spline interpolation.
8. The camera of claim 1, wherein said subsample resolution representation is determined using bi-cubic interpolation.
14. The portable digital camera of claim 1, wherein the subsample resolution representation is generated in parallel with the main image.
18. A portable digital camera having no photographic film, comprising:
(a) an integral flash for providing illumination during image acquisition,
(c) a red-eye filter for correcting a red eye defect within the main image acquired by the main image sensor based on analysis of the low resolution image acquired by the separate sensor including the subsample representation of the one or more selected regions of the main image;
(f) wherein the meta data comprises identified red areas determined not to be red eye regions.
19. A portable digital camera having no photographic film, comprising:
(f) wherein the meta data comprises colors of regions that are not red prior to activation of the flash, wherein such regions appearing red in the main image are identified as having a certain enhanced probability of comprising red eye artifact.
(d) acquiring with the separate sensor a low resolution image temporally proximate to acquisition of the main image and including a subsample resolution representation of one of the main image; and
(e) correcting a red eye defect within the main image acquired by the main image sensor based on an analysis of the low resolution image acquired by the separate sensor including the subsample resolution representation of the main image;
(f) a dedicated hardware subsystem which is provided low resolution image data directly from the separate sensor; and
(g) a main system memory which receives raw image data and metadata as implemented by the dedicated hardware subsystem; and
(h) wherein the main system memory is configured to receive meta data that comprises identified red areas determined not to be red eye regions.
21. The method of claim 20, further comprising changing a degree of subsampling.
36. A method of correcting a red eye defect within a digital image, comprising:
providing a portable digital camera including a main image sensor for capturing a main image and a separate sensor for acquiring a low resolution image temporally proximate to acquisition of the main image;
providing illumination during main image acquisition with a flash;
acquiring a main image with the main image sensor;
acquiring with the separate sensor a low resolution image temporally proximate to acquisition of the main image and including a subsample representation of one or more selected regions of the main image; and

37. A method of correcting a red eye defect within a digital image, comprising:
wherein the metadata comprises colors of regions that are not red prior to activation of the flash, wherein such regions appearing red in the main image are identified as having a certain enhanced probability of comprising red eye artifact.
(c) acquiring with the separate sensor a low resolution image temporally proximate to acquisition of the main image and including a subsample resolution representation of one of the main image; and
(d) correcting a red eye defect within the main image acquired by the main image sensor based on an analysis of the low resolution image acquired by the separate sensor including the subsample resolution representation of the main image;
(e) a dedicated hardware subsystem which is provided low resolution image data directly from the separate sensor; and
(f) a main system memory which receives raw image data and metadata as implemented by the dedicated hardware subsystem; and
(g) wherein the main system memory is configured to receive meta data that comprises identified red areas determined not to be red eye regions.
39. The one or more storage media of claim 38, wherein the method further comprises changing a degree of subsampling of said subsample resolution representation.
44. The one or more storage media of claim 38, wherein the method further comprises determining said subsample resolution representation using spline interpolation.

54. One or more digital storage media having code embodied therein for programming one or more processors of a portable digital camera that includes a main image sensor and a separate low resolution sensor to perform a method of correcting a red eye defect within a digital image, wherein the method comprises:
providing low resolution image data directly from the separate sensor to a dedicated hardware subsystem;
55. One or more digital storage media having code embodied therein for programming one or more processors of a portable digital camera that includes a main image sensor and a separate low resolution sensor to perform a method of correcting a red eye defect within a digital image, wherein the method comprises:
wherein the metadata comprises colors of non-red regions that are not red prior to activation of the flash, wherein such non-red regions appearing red in the main image are identified as having a certain enhanced probability of comprising red eye artifact.
