Abstract: An image processing circuit includes a gain calculation circuit and a digital amplifier. The gain calculation circuit calculates a first gain with which an average color-difference value in a whole region of a pickup image is brought close to a predetermined convergent point. The digital amplifier performs correction of a white balance of a pixel of the pickup image with a candidate pixel that is of a first candidate pixel calculated based on the first gain and a second candidate pixel calculated based on a second gain associated with each of divided regions and in which a color-difference component is closer to the predetermined convergent point.
Abstract: The invention relates to systems, methods, and computer readable media for responding to a user snapshot request by capturing anticipatory pre-snapshot image data as well as post-snapshot image data. The captured information may be used, depending upon the embodiment, to create archival image information and image presentation information that is both useful and pleasing to a user. The captured information may automatically be trimmed or edited to facilitate creating an enhanced image, such as a moving still image. Varying embodiments of the invention offer techniques for trimming and editing based upon the following: exposure, brightness, focus, white balance, detected motion of the camera, substantive image analysis, detected sound, image metadata, and/or any combination of the foregoing.

Abstract: Embodiments of the disclosure provide systems and methods for motion capture to generate content (e.g., motion pictures, television programming, videos, etc.). An actor or other performing being can have multiple markers on his or her face that are essentially invisible to the human eye, but that can be clearly captured by camera systems of the present disclosure. Embodiments can capture the performance using two different camera systems, each of which can observe the same performance but capture different images of that performance. For instance, a first camera system can capture the performance within a first light wavelength spectrum (e.g., visible light spectrum), and a second camera system can simultaneously capture the performance in a second light wavelength spectrum different from the first spectrum (e.g., invisible light spectrum such as the IR light spectrum). The images captured by the first and second camera systems can be combined to generate content.

Abstract: An imaging apparatus includes an angular velocity sensor that detects a shake and a motion vector detection unit that detects a motion of a subject, and optically corrects an image blur by moving a shift lens. In a mode for supporting panning imaging, a shutter speed calculation unit calculates first and second exposure times as an exposure time of an imaging element. The first exposure time is calculated using a shake detection signal, a motion amount of a subject image, a focal distance of an imaging optical system, and a set value of a flow effect of a background image. The second exposure time is calculated from the shake detection signal, the motion amount of the subject image, a position and a maximum correction angle of a shift lens. If the first exposure time exceeds the second exposure time, processing of preferentially determining the second exposure time is performed.

Abstract: In aspects of digital image color space channel blending, a camera device can capture digital images that encompass a three-hundred and sixty degree (360°) field of view. An image blending module is implemented to combine the digital images along a seam between the digital images to form a blended image. To combine the digital images, the image blending module can determine mismatched color between the digital images along the seam within an overlap region that overlaps two of the digital images along the seam. The image blending module can then blend the digital images by channel gains in a color space applied to enhance pixels of one of the digital images starting within the overlap region along the seam and blending into the one digital image.
