  • Patent number: 9883164
    Abstract: The invention is directed to systems, methods and computer program products for optimizing usage of image sensors in a stereoscopic environment. The method includes: (a) providing a first image sensor, where the first image sensor is associated with a first image sensor area and a first imaging area; (b) determining a distance from the camera to an object to be captured; and (c) shifting the first imaging area along a length of the first image sensor area, where the amount of the shifting is based at least partially on the distance from the camera to the object, and where the first imaging area can shift along an entire length of the first image sensor area. The invention optimizes usage of an image sensor by permitting an increase in disparity control. Additionally, the invention reduces the closest permissible distance of an object to be captured using a stereoscopic camera.

  • Patent number: 9554107
    Abstract: A method and apparatus for recording a composite image from a lens array are disclosed. A first composite image is recorded using a first lens providing imaging data in a first color, a second lens providing imaging data in a second color, and a third lens providing imaging data in a third color, wherein the first, second, and third colors are different colors. A second composite image is recorded using the first lens, a fourth lens providing imaging data in the second color, and a fifth lens providing imaging data in the third color. The first and second composite images are compared to identify color fringed areas. Based on the relative size and location of the color fringed areas in the first and second composite images, a de-fringing algorithm is applied to at least one of the composite images to mitigate the color fringing in the color fringed areas.

  • Patent number: 9113385
    Abstract: The invention relates to a method in a source radio base station (14) for enabling a handover of a connection to a user equipment (13) from a source cell (11) to a target cell (17). The source radio base station (14) serves the source cell (11) and is comprised in a radio communications network (100). The source radio base station receives (802) at least a first segment of a measurement report from the user equipment (13), which measurement report indicates received signal power of signals of neighboring cells. The source radio base station then determines (803) a transmission time of the segment of the measurement report and compares (804) the transmission time with a predefined time threshold value. When the transmission time has exceeded the time threshold value, the source radio base station determines (806) whether to perform the handover based on the at least first segment of the measurement report.
