  • Patent number: 10963707
    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: 10649313
    Abstract: Disclosed are an electronic apparatus that achieves both the convenience of touch operation and accurate position specification, and a method for controlling the same. When an area that meets a predetermined condition has been detected in an image, the electronic apparatus executes a function corresponding to a position where a touch has been detected by touch detection means. When the area that meets the predetermined condition has not been detected or area detection is not carried out, the electronic apparatus carries out a process corresponding to an operation for moving a touched position rather than carrying out processing corresponding to the position where the touch has been detected by the touch detection means.

  • Patent number: 10621769
    Abstract: A method and system. A base photographic image of a scene is combined with N additional photographic images of the scene to form a composite image including M discrete light sources (N?2; M?N). The scene in the base image is exposed to ambient light. The scene of the base image is exposed, in each of the N additional images, to the ambient light and to at least one discrete light source to which the base image is not exposed. The M discrete light sources in the composite image include the discrete light sources to which the scene is exposed in the N additional images. The composite image includes a region surrounding each discrete light source and has an area that correlates with an intensity of light from the discrete light source surrounded by the region. The intensity of light is the intensity at the discrete light source where the light is emitted.

  • Patent number: 10614775
    Abstract: An electronic device may have a main display and an ancillary display that forms a dynamic function row. The device may also have a backlit keyboard with glyphs. The keyboard may have light-emitting diodes that emit backlight illumination. The backlight illumination has a backlight illumination color and intensity. A color ambient light sensor may measure ambient light color and intensity. Control circuitry in the laptop computer may make white point adjustments to the main and ancillary displays. White point adjustments may be made based on factors such as the backlight illumination intensity, information on the nominal white point of a display (which may be comparable to the color of the backlight illumination), information on the ambient light color and intensity, and a white point adaptation scaling factor.

  • Patent number: 10602071
    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.
