  • Patent number: 10721448
    Abstract: A method, system and computer program are provided that present a real-time approach to Chromaticity maximization to be used in image segmentation. The ambient illuminant in a scene may be first approximated. The input image may then be preprocessed to remove the impact of the illuminant, and approximate an ambient white light source instead. The resultant image is then choma-maximized. The result is an adaptive Chromaticity maximization algorithm capable of adapting to a wide dynamic range of illuminations. A segmentation algorithm is put in place as well that takes advantage of such an approach. This approach also has applications in HDR photography and real-time HDR video.

    Abstract: The present disclosure relates to an imaging device and a control method that achieve low electric power consumption. A light source is of a wavelength received by an OPD pixel which is a pixel that detects light exposure, and its light emission is controlled by a PC or the like. The OPD pixel is a pixel specialized to detect a brightness of an imaging environment, and converts a received light amount to a current value, without electric power consumption, by utilizing photoelectric conversion. A detector detects a change (light intensity, light reception time, blinking pattern, etc.) of the current value of the OPD pixel, and upon detection, issues an operation instruction to another device (not depicted) or a solid state imaging device, by supplying a detection result to a control unit. The present disclosure can be applied to the solid state imaging device that includes the OPD pixel, for example.

    Abstract: The disclosure concerns estimating an illumination spectrum of a pixel of hyperspectral or multispectral image data. A processor determines an optimised illumination spectrum for a first point based on an initial illumination spectrum and based on associations between the first point and multiple second points of multiple instances of the image data, wherein each of the multiple instances is associated with a refined amount of image information. It is possible to determine the illumination spectrum per pixel of the original image data without clustering pixels or restrictive assumptions but instead by utilising the associations for the statistical inference on the illumination spectrum.

  • Patent number: 10509970
    Abstract: An autonomous vehicle is configured to detect an active turn signal indicator on another vehicle. An image-capture device of the autonomous vehicle captures an image of a field of view of the autonomous vehicle. The autonomous vehicle captures the image with a short exposure to emphasize objects having brightness above a threshold. Additionally, a bounding area for a second vehicle located within the image is determined. The autonomous vehicle identifies a group of pixels within the bounding area based on a first color of the group of pixels. The autonomous vehicle also calculates an oscillation of an intensity of the group of pixels. Based on the oscillation of the intensity, the autonomous vehicle determines a likelihood that the second vehicle has a first active turn signal. Additionally, the autonomous vehicle is controlled based at least on the likelihood that the second vehicle has a first active turn signal.

  • Patent number: 10499028
    Abstract: A non-emission image is obtained by a non-emission image obtaining unit in a state in which a plurality of flash devices do not emit light. Pre-emission images are obtained by an emission image obtaining unit in a state in which the plurality of flash devices individually emits light. Flash light irradiation areas are specified by a flash light irradiation area specifying unit based on a signal value difference of a plurality of division areas of the non-emission image and each of the emission images. A priority flash device selecting unit selects a priority flash device as a target of white balance (WB) adjustment. A WB adjusting unit performs WB adjustment based on signal values of irradiation areas of the selected priority flash device.

  • Patent number: 10482582
    Abstract: Systems and methods are provided for the denoising of images in the presence of broadband noise based on the detection and/or estimation of in-band noise. According to various example embodiments, an estimate of broadband noise that lies within the imaging band is made by detecting or characterizing the out-of-band noise that lies outside of the imaging band. This estimated in-band noise may be employed for denoise the detected imaging waveform. According to other example embodiments, a reference receive circuit that is sensitive to noise within the imaging band, but is isolated from the imaging energy, may be employed to detect and/or characterize the noise within the imaging band. The estimated reference noise may be employed to denoise the detected in-band imaging waveform.

  • Patent number: 10469849
    Abstract: A method for processing image and video data, comprising providing high dynamic range image data (HDR) and a corresponding low dynamic range image data (LDR). The LDR image is encoded in a legacy code stream, while a residual code stream is generated and encoded containing data necessary for the reconstruction of the HDR image in a decoding phase. To generate the residual code stream, LDR image data are processed so as to obtain a processed LDR* image, then a component data of the HDR image and a corresponding component of the processed LDR* image are selected and residual data of the selected component data are calculated by dividing the component of the processed LDR* image data by the component of the HDR image data. The residual data of the selected component are scaled into the range of values comprised between 0 and 1 and are then encoded in a residual code stream. A decoding method is also disclosed which allows reconstruction of an HDR image from a legacy code stream and a residual data code stream.
