20140015995 | Image Capture Accelerator - An image capture accelerator performs accelerated processing of image data. In one embodiment, the image capture accelerator includes accelerator circuitry including a pre-processing engine and a compression engine. The pre-processing engine is configured to perform accelerated processing on received image data, and the compression engine is configured to compress processed image data received from the pre-processing engine. In one embodiment, the image capture accelerator further includes a demultiplexer configured to receive image data captured by an image sensor array implemented within, for example, an image sensor chip. The demultiplexer may output the received image data to an image signal processor when the image data is captured by the image sensor array in a standard capture mode, and may output the received image data to the accelerator circuitry when the image data is captured by the image sensor array in an accelerated capture mode. | 01-16-2014 |

20140152871 | IMAGE SENSOR DATA COMPRESSION AND DSP DECOMPRESSION - An image sensor compresses image data prior to transmitting the image data to a DSP. The image sensor captures light representing an image, for instance via a camera's aperture. A focal plane array converts the captured light into pixel data. The pixel data is sorted into categories, and is compressed in parallel by a compression engine. The compressed pixel data is then sent to a DSP, which may be located off-chip. The DSP then decompresses the compressed pixel data, performs image signal processing operations on the compressed pixel data, and then compresses the processed pixel data into a digital image format. The image sensor may buffer the pixel data for one or more images to accommodate for slowdown by the compression engine. The pixel data may be sorted by row and column of a pixel array. Alternatively, the pixel data may be sorted by color from a Bayer color filter. | 06-05-2014 |

20140232892 | DIGITAL SIGNAL PROCESSOR BUFFER MANAGEMENT - A camera image sensor captures image data at a first rate, and stores the captured image data at a DSP buffer until it is processed by a DSP image processor. In response to the available capacity at the DSP buffer falling below a first threshold, the DSP buffer notifies the image sensor of the buffer's status, and the image sensor is configured to capture image data at a second rate. The second rate can be associated with a frame rate lower than the frame rate associated with the first rate, and/or can be associated with a resolution less than the resolution associated with the first rate. When the available capacity of the DSP increases, for instance, above a second threshold, the image sensor can be re-configured to capture image data at the first rate, or at a third rate different from the second rate and first rate. | 08-21-2014 |
20140267894 | Wireless Surface Illuminators - A camera system includes a wireless indicator that emits light to provide signals to a user. This wireless indicator is attached to a lens casing that covers the front face of the camera to protect components of the camera such as the lens. A wireless signal interface on the front face of the camera is configured to emit ultraviolet light in response to control circuitry within the camera. The ultraviolet light is transmitted through the lens casing to an excitable element. The excitable element produces visible light in response to the ultraviolet light. Any re-emitted visible light that travels back towards the camera lens and image sensor is reflected by a reflective layer, which is configured to transmit ultraviolet light while reflecting visible light. Therefore, the wireless indicator does not cause light artifacts or image flaws to appear in images captured by the image sensor. | 09-18-2014 |
20150049243 | Camera Heat Sink - A camera includes a camera body having a camera lens structured on a front surface of the camera body and electronics internal to the camera body for capturing images via the camera lens. A thermally conductive material is thermally coupled to the electronics and exposed on an external face of the camera body. The thermally conductive material transfers heat produced by the electronics to the external face of the camera, and a removable heat sink removably couples to the thermally conductive material. The camera further includes a housing structured to at least partially enclose the camera body. The housing is structured to enable at least a portion of the removable heat sink to protrude through the housing. | 02-19-2015 |
20150062360 | EDGE-BASED ELECTRONIC IMAGE STABILIZATION - An image stabilization system applies a “pinned-edge” or “soft pinned edge” image stabilization technique to digital video to compensate for unwanted camera motion in a captured video. In these stabilization techniques, a warping function is applied to an image frame to achieve a non-uniform shifting of depicted points in the image frame such that a reference point is stabilized with respect to a reference frame. In pinned-edge image stabilization, the final stabilized output video has the same dimensions as the pre-stabilized input video captured by the image sensor. In soft pinned-edge image stabilization, the pre-stabilized input video has slightly larger dimensions than the stabilized output video but these larger dimensions are still reduced compared to traditional electronic image stabilization. | 03-05-2015 |
20150062383 | CINEMATIC IMAGE BLUR IN DIGITAL CAMERAS BASED ON EXPOSURE TIMING MANIPULATION - Cinematic motion blur and other cinematic effects are enabled during image capture through exposure timing manipulation. The resulting captured images and videos include one or more cinematic effects without the need for a user to impose the cinematic effects post-capture. | 03-05-2015 |
20150077586 | Conversion Between Aspect Ratios in Camera - A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image. | 03-19-2015 |
