摘要： Flash image orb artifacts arising from specular reflections from airborne particles are corrected. A specific location is detected within a digital image of a flash image airborne particle artifact (orb). A defined curved plane shape is electronically identified within the image. Luminances are analyzed of pixels within the identified shape to assess whether the shape in fact corresponds to an orb. The digital image is corrected by removing the orb. One or more pixel values are adjusted inside the orb, and one or more edge pixel values of the orb are also adjusted.

摘要： A smart-focusing technique includes identifying an object of interest, such as a face, in a digital image. A focus-generic classifier chain is applied that is trained to match both focused and unfocused faces and/or data from a face tracking module is accepted. Multiple focus-specific classifier chains are applied, including a first chain trained to match substantially out of focus faces, and a second chain trained to match slightly out of focus faces. Focus position is rapidly adjusted using a MEMS component.

摘要： Methods and systems for detecting and correcting chromatic aberration and purple fringing are disclosed. Chromatic aberration can be addressed by separating an image into color planes and then adjusting these to reduce chromatic aberration by using a specific calibration image (calibration chart) as an empirical method to calibrate the image acquisition device. Purple fringing can be corrected by initially addressing color aberration resulting from the lateral chromatic aberration (LCA). The LCA is first removed and then the correction is extended to purple fringing. A discovery is relied upon that the purple fringing is created in the direction of the chromatic aberration and is more pronounced in the direction of the chromatic aberration.

摘要： A wide field angle camera module that incorporates field curvature correction suitable for an electronic device is described herein. By way of example, the wide field angle camera module comprises micro optical lenses adapted to capture field angles of greater than thirty degrees, and is further adapted to provide field curvature correction for a range of object distances, and for a range of zoom configurations include 1×, 2× and 3× zoom configurations. Furthermore, the field correction can be implemented alone or in conjunction with signal processing that corrects barrel distortion introduced by the micro optical lenses. In particular aspects, the field correction can be automated based on image quality analysis to provide a high quality image for object distances substantially 30 centimeters or larger.

摘要： A method of detecting a face in an image includes performing face detection within a first window of the image at a first location. A confidence level is obtained from the face detection indicating a probability of the image including a face at or in the vicinity of the first location. Face detection is then performed within a second window at a second location, wherein the second location is determined based on the confidence level.

摘要： A method and device is provided for adjusting the white balance of a digital image by adjusting the values assigned to the red, green, and blue subpixels of a pixel in the image. The adjustment to the subpixels is determined by identifying pixels in the image that have an RGB product greater than a threshold value, wherein the threshold value is based at least in part on an average of the RGB products of each pixel in the image and a variance between the RGB products of the pixels and the average of the RGB products.
