US9883119 – Method and system for hardware-based motion sensitive HDR image processing<\/h3>\n

Inventor: Kalin Mitkov Atanassov, Sergiu Radu Goma, Stephen Michael Verrall, Albrecht Johannes Lindner<\/h5>\n
Current Assignee: Qualcomm Inc<\/h5>\n

<\/span><\/p>\n

Abstract<\/h3>\n
<\/div>\n
System and methods for performing motion sensitive high dynamic range (HDR) image processing. A saturation analysis circuit is configured to receive a set of image data corresponding to portions of a set of image frames having different exposures time from a lowest exposure time to a highest exposure time, and select image data from a frame that does not exceed the saturation threshold value. A motion detection circuit may be configured to determine whether the image data is associated with movement, by comparing image data from pairs of frames of adjacent exposure times, and changing the selection to a lower exposure time frame if movement is detected. By selecting which exposure time is used based upon movement in the image frame, ghosting and blurring in HDR images containing movement can be reduced.<\/div>\n

<\/span><\/p>\n

Abstract<\/h3>\n
<\/div>\n
Various embodiments are directed to an image sensor that includes a first sensor portion and a second sensor portion coupled to the first sensor portion. The second sensor portion may be positioned relative to the first sensor portion so that the second sensor portion may initially detect light entering the image sensor, and some of that light passes through the second sensor portion and is be detected by the first sensor portion. In some embodiments, the second sensor portion may be configured to have a thickness suitable for sensing visible light. The first sensor portion may be configured to have a thickness suitable for sensing IR or NIR light. As a result of the arrangement and structure of the second sensor portion and the first sensor portion, the image sensor captures substantially more light from the light source.<\/div>\n

US10068338 – Active sensing spatial resolution improvement through multiple receivers and code reuse<\/h3>\n

Inventor: Kalin Mitkov Atanassov, Sergiu Radu Goma<\/h5>\n
Current Assignee: Qualcomm Inc<\/h5>\n

<\/span><\/p>\n

Abstract<\/h3>\n
<\/div>\n
Structured light active sensing systems transmit and receive spatial codes to generate depth maps. Spatial codes can’t be repeated within a disparity range if they are to be uniquely identified. This results in large numbers of codes for single transmitter\/single receiver systems, because reflected ray traces from two object locations may be focused onto the same location of the receiver sensor, making it impossible to determine which object location reflected the code. However, the original code location may be uniquely identified because ray traces from the two object locations that focus onto the same location of the first receiver sensor may focus onto different locations on the second receiver sensor. Described herein are active sensing systems and methods that use two receivers to uniquely identify original code positions and allow for greater code reuse.<\/div>\n

US9386222 – Multi-camera system using folded optics free from parallax artifacts<\/h3>\n

Inventor: Todor Georgiev Georgiev, Thomas Wesley Osborne, Sergiu Radu Goma<\/h5>\n
Current Assignee: Qualcomm Inc<\/h5>\n

<\/span><\/p>\n

Abstract<\/h3>\n
<\/div>\n
Aspects relate to an array camera exhibiting little or no parallax artifacts in captured images. For example, the planes of the central mirror surfaces of the array camera can be located at a midpoint along, and orthogonally to, a line between the corresponding camera location and the virtual camera location. Accordingly, the cones of all of the cameras in the array appear as if coming from the virtual camera location after folding by the mirrors. Each sensor in the array \u201csees\u201d a portion of the image scene using a corresponding facet of the central mirror prism, and accordingly each individual sensor\/mirror pair represents only a sub-aperture of the total array camera. The complete array camera has a synthetic aperture generated based on the sum of all individual aperture rays.<\/div>\n

US9560296 – Pixel readout architecture for full well capacity extension<\/h3>\n

Inventor: Biay-Cheng Hseih, Jiafu Luo, Sergiu Radu Goma<\/h5>\n
Current Assignee: Qualcomm Inc<\/h5>\n

<\/span><\/p>\n

Abstract<\/h3>\n
<\/div>\n
Certain aspects relate to systems and techniques for full well capacity extension. For example, a storage capacitor included in the pixel readout architecture can enable multiple charge dumps from a pixel in the analog domain, extending the full well capacity of the pixel. Further, multiple reads can be integrated in the digital domain using a memory, for example DRAM, in communication with the pixel readout architecture. This also can effectively multiply a small pixel’s full well capacity. In some examples, multiple reads in the digital domain can be used to reduce, eliminate, or compensate for kTC noise in the pixel readout architecture.<\/div>\n

Described herein are methods and devices that employ a plurality of image sensors to capture a target image of a scene. As described, positioning at least one reflective or refractive surface near the plurality of image sensors enables the sensors to capture together an image of wider field of view and longer focal length than any sensor could capture individually by using the reflective or refractive surface to guide a portion of the image scene to each sensor. The different portions of the scene captured by the sensors may overlap, and may be aligned and cropped to generate the target image.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
A method operational on a transmitter device is provided for projecting a composite code mask. A composite code mask on a tangible medium is obtained, where the composite code mask includes a code layer combined with a carrier layer. The code layer may include uniquely identifiable spatially-coded codewords defined by a plurality of symbols. The carrier layer may be independently ascertainable and distinct from the code layer and includes a plurality of reference objects that are robust to distortion upon projection. At least one of the code layer and carrier layer may be pre-shaped by a synthetic point spread function prior to projection. At least a portion of the composite code mask is projected, by the transmitter device, onto a target object to help a receiver ascertain depth information for the target object with a single projection of the composite code mask.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
Described herein are methods and apparatus to adjust the convergence point of a stereoscopic image pair captured by an imaging device. In one method, a first image and a second image of a stereoscopic image pair are provided, and then shifting or cropping of the first image is performed to align the first and second image. This shifting or cropping is performed while preserving the second image. The method then includes determining a target horizontal image disparity based on a desired convergence point of the stereoscopic image pair and when the target horizontal disparity is greater than a predetermined maximum, the cropping of an outside dimension of the first image is limited. In some implementations it is limited to the predetermined maximum.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
A graphics multi-media integrated circuit (GMIC) is connected to a host processor over two serial links: a half duplex bi-directional serial link which accords to a protocol defined for a display serial interface, and a uni-directional serial link which accords to a compatible protocol defined for a camera serial interface. The GMIC receives packets according to the protocol from the host over the half duplex bi-directional serial link and processes these packets. The GMIC sends packets according to the protocol to the host over the uni-directional serial link. A packet from the host can request a processing operation by the GMIC or can initiate a memory operation at the memory of the GMIC. The GMIC can also send packets to the host to initiate a memory operation at the memory of the host. The GMIC may be connected to a display over a bi-directional serial link according to the display serial interface protocol and to a camera over a uni-directional serial link and a bi-directional control link according to the camera serial interface so that the host controls the display and camera indirectly through the GMIC.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
A buffer is associated with each of a plurality of data lanes of a multi-lane serial data bus. Data words are timed through the buffers of active ones of the data lanes. Words timed through buffers of active data lanes are merged onto a parallel bus such that data words from each of the active data lanes are merged onto the parallel bus in a pre-defined repeating sequence of data lanes. This approach allows other, non-active, data lanes to remain in a power conservation state.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
At least one illuminant white point estimate is determined in a color space having radially defined saturation based on a reference image. A chromatic adaptation correction vector (CACV) is determined based on the at least one illuminant white point estimate. Corrected pixels are obtained by applying the CACV (preferably in a cone response color space using a correction matrix based on the CACV) to uncorrected image pixels corresponding to a target image, which may comprise the reference image or another image.<\/div>\n

US7599569 – Method and apparatus for bilateral high pass filter<\/h3>\n

Inventor: Maxim Smirnov, Milivoje Aleksic, Sergiu Goma<\/h5>\n
Current Assignee: Ati Technologies, Ulc<\/h5>\n

<\/span><\/p>\n

Abstract<\/text><\/h3>\n
<\/div>\n
A target pixel and surrounding pixels corresponding to the target pixel are obtained from a digitally represented image. A bilateral high pass filtering kernel is determined based at least in part upon the target pixel and the surrounding pixels. A high pass spatial filtering kernel is provided and multiplied with the high pass photometric filtering kernel to provide a bilateral high pass filtering kernel. The resulting bilateral high pass filtering kernel is thereafter applied to the target pixel and the surrounding pixels to provide a filtered pixel. When it is desirable to combine noise filtering capabilities with sharpening capabilities, the bilateral high pass filter of the present invention may be combined with a bilateral low pass filtering kernel to provide a combined noise reduction and edge sharpening filter. The present invention may be advantageously applied to a variety of devices, including cellular telephones that employ image sensing technology.<\/span><\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
To derive a Hamming code to manage data errors a set of at least four parity bit positions is selected for parity bits which will protect a set of data bits (where each data bit has a data bit position in the data bit set). A syndrome is determined for each data bit position. This involves selecting a unique sub-set of at least three parity bit positions. The unique sub-set shares at least one parity bit position with at least one other unique sub-set of at least three parity bit positions. A parity bit value may then be calculated for each parity bit position based on the determined syndromes. The header of a packet may be provided with a word which defines the length of the packet and an error management code generated utilizing this word so that errors in the word may be detected and, possibly, corrected.<\/div>\n

Abstract<\/text><\/h3>\n
<\/div>\n
A method of operating a shared bus comprises sending a wake-up signal on the shared bus. The wake-up signal comprises a sequence of signals, each signal of the sequence being one of a signal indicating the bus is free and a signal indicating the bus is busy. A microcontroller to effect this method is also contemplated. A wake-up device for a shared bus has a first latch to recognize a signal indicating one of said shared bus being free and said shared bus being busy and selectively output a recognition signal and a second latch to, after receipt of the recognition signal, recognize a signal indicating another of the shared bus being free and the shared bus being busy and selectively output a power-on signal. The latches may be D-type flip flops.<\/div>\n
