摘要:
When using a strobe in capturing a digital image is determined to be imminent, a pre-capture image may be saved from which iris-color information can be derived. The iris-color information derived from the pre-capture image may be used to improve red-eye correction of the captured digital image.

Systems and methods of implementing dynamic focus zones for cameras are disclosed. In an exemplary implementation, a method may include selecting a reference image from a scene being photographed. The method may also include selecting a plurality of difference images from regions adjacent the reference image. The method may also include comparing the reference image and the plurality of different images. The method may also include selecting a plurality of distinct focus zones based on correlation of the compared reference image and the plurality of difference images.

Disclosed are digital imaging devices that embody a method or algorithm for transitioning from a displayable focus process to a high speed focus process which can be displayed, and wherein the transition is accomplished in a seamless fashion. In addition, the digital imaging devices may embody a method for quickly verifying the focus quality of the image. If the focus quality is acceptable, the device indicates that focus is good and avoids a long auto-focus time.
摘要:
A method comprises determining whether a digital imaging device is in a stable state or an unstable state and causing an event to be performed upon the digital imaging device transitioning from the unstable state to the stable state. The method also comprises precluding the event from being performed while the digital imaging device is in the unstable state.

A digital camera takes interleaved photographs of two different kinds. In one example embodiment, the first kind of photograph is taken using a first set of pixels of the camera's electronic array light sensor and has a short exposure time. The second kind of photograph is taken using a second set of pixels and has a long exposure time. More than one of the short-exposure-time photographs is taken while each long-exposure-time photograph is exposed. The two kinds of photographs are used for different purposes. For example, one kind may be used for performing automatic focusing while the other kind is used for displaying in a live view display. In this way, live view may continue while automatic focusing is performed. In another embodiment, one kind of photograph is used for providing a live view display, and the other is used in selecting exposure settings for a final photograph.

A digital imaging device automatically detects that a subject is too close to the device for acceptable focus to be achieved and informs the user, takes automatic corrective action, or both.
摘要:
An image contains a representation of a person's face, where the image has plural points each comprising multiple components of a color space. For each of the plural points, at least two of the color space components are combined to produce a respective aggregate value. The image is processed to convert at least some of the points of the image based on the calculated aggregate values.
摘要:
Face-detection processing methods, image processing devices, and articles of manufacture are described. According to one arrangement, a face-detection processing method includes accessing image data of a plurality of images to be processed for detection of human faces in the images, determining whether or not to use skin-detection processing for face-detection processing of individual ones of the images, and in accordance with the determining, performing the face-detection processing of one of the images using the skin-detection processing to detect human faces in the one of the images and performing the face-detection processing of another of the images without using the skin-detection processing to detect human faces in the another of the images.
