摘要： An image sensing system provide feature tone detection. A feature tone detection module receives illumination compensated pixel data. To perform feature tone identification the illumination compensated pixel data is transformed to a color space having hue and saturation and then compared against pre-selected ranges of hue and saturation. Noise filtering is performed using an erosion-dilation process. A bit code is used to identify pixels having a specified feature tone, such as a skin tone.

摘要： Systems and methods resume capture of a base image from an object by a mobile scanner operated by a user. An indication of an overlap area on a base image displayed within a computer display is received. A scan image is received from the mobile scanner positioned on the object at a location corresponding to the overlap area. A match between a segment of the scan image and a corresponding segment of the base image is determined, where the match defines a location and orientation of the mobile scanner relative to the base image. An indication that the scan has resumed is made to the user when the match is found, and images that are subsequently received from the mobile scanner are stitched to the base image based upon the determined location and orientation. The partially formed base image and the scanner image are concurrently displayed to the user.

摘要： A method for combining images includes capturing a first image including a subject from a first camera. A second image is captured from a second camera and the second image includes the subject. First pre-processing functions are applied on the first image to produce a first processed image. The first pre-processing functions include applying a distortion component of a rotation matrix to the first image. The rotation matrix defines a corrected relationship between the first and the second image. Second pre-processing functions are applied on the second image to produces a second processed image. The second pre-processing functions include applying the rotation matrix to the second image. The first processed image and the second processed image are blended in a processing unit to form a composite image.

摘要： An image sensor includes an array of light sensitive elements and a filter array. Each filter element is in optical communication with a respective light sensitive element. The image sensor receives filtered light having a repeating pattern. Light sensitive elements in at least two successive rows alternately receive light having a first color and a second color, and light sensitive elements in common columns of the successive rows alternately receive light having the first color and the second color. Light sensitive elements in at least two additional successive rows alternately receive light having a third and a fourth color, and light sensitive elements in common columns of the additional successive rows alternately receive light having the third color and the fourth color. Output values of pairs of sampled light sensitive elements receiving light of a common color and from successive rows are combined to generate a down-sampled image.
