Combined Automatic Gain Control And Exposure Control (i.e., Sensitivity Control) Patents (Class 348/229.1)
  • Patent number: 10602075
    Abstract: In some embodiments, an image capture device receives a capture command to capture an image. Exposure adjustment operations are subsequently performed. These operations include determining that a first luminance indicated by first image data, which is obtained using a first exposure value, exceeds a threshold luminance. The operations also include decreasing, based on the threshold luminance being exceeded, the first exposure value to a second exposure value. The operations also include determining, from second image data obtained using the second exposure value, that a second luminance indicated by the second image data is less than the threshold luminance. The HDR setting of the image capture device is configured to include a bracket of exposure values, where the second exposure value is a minimum exposure value from the bracket of exposure values. The image capture device executes a capture operation in which an image bracket is captured using this HDR setting.

  • Patent number: 10539791
    Abstract: Split exit pupil (or split eye-box) heads-up display (HUD)systems and methods are described. The described HUD system methods make use of a split exit pupil design method that enables a modular HUD system and allows the HUD system viewing eye-box size to be tailored while reducing the overall HUD volumetric aspects. A HUD module utilizes a high brightness small size micro-pixel imager to generate one or more HUD virtual images with a one or a plurality of given viewing eye-box segment sizes. When integrated together into a HUD system, a multiplicity of such HUD modules displaying the same image would enable such an integrated HUD system to have an eye-box size that is substantially larger than the eye-box size of a HUD module. The resultant integrated HUD system volume is substantially volumetrically smaller than a HUD system that uses a single larger imager.

  • Patent number: 10187607
    Abstract: An image sensor may generate visual output signals conveying visual information within a field of view of the image sensor. First and second video information defining first and video content may be generated based on the visual output signals. The first video content may be captured using a first capture frame rate and the second video content may be captured using a second capture frame rate. Motion of the image sensor and/or motion of an object within the field of view may be determined. The first capture frame rate may be changed based on the determined motion. Third video information defining third video content may be generated based on the first video information and the second video information. The third video content may include one or more frames of the first video content and one or more frames of the second video content.

  • Patent number: 10178327
    Abstract: An imaging unit causes each exposure corresponding to one frame period of respective second image signals in a first mode, and causes each exposure in divided sections of one frame period of the respective second image signals under different imaging conditions in a second mode. An image processing unit generates frames of respective first image signals based on each imaging signal read out in such a manner as to correspond to each exposure corresponding to one frame period in the first mode, and generates frames of the respective first image signals based on each imaging signal read out in such a manner as to correspond to each exposure of the divided sections in the second mode. An image output unit sequentially outputs frames of the second image signals set to a signal format common to the first mode and the second mode.

  • Patent number: 10158809
    Abstract: To prevent an increase in memory capacities in a device for performing image combination. A data generation unit executes long exposure processing and short exposure processing in sequence, the long exposure processing being performed to generate data including a plurality of pixel data items as long exposure data by performing exposure over a longer time period of two different exposure time periods, the short exposure processing being performed to generate data including a plurality of pixel data items as short exposure data by performing exposure over a shorter time period of the two different exposure time periods after the long exposure processing. A compression unit compresses the long exposure data to generate compression data. A memory holds the compression data over delay time corresponding to the shorter time period of the two exposure time periods. A decompression unit decompresses the held compression data to restore the long exposure data.

  • Patent number: 10129462
    Abstract: Augmented reality can be used to display previously captured images on a viewfinder of a camera as the camera's active position nears a position from which the picture was originally taken. A histogram file may associate the original image with positional information of the camera when the image was captured. When the cameras active position nears those coordinates, a transparent version of the digital image is displayed on the viewfinder of the camera. The positional information may include a spatial location of the camera (e.g., GPS coordinates, etc.) as well as an orientation of the camera (e.g., yaw, pitch, roll, etc.). Augmented reality can be used to guide the user to configure/re-configure the camera in order to correct (or avoid) an image quality issue/defect when re-taking a picture.

  • Patent number: 10121453
    Abstract: The present invention relates to a bit rate controller comprising: a light determination block configured to determine a light level in images of a captured scene; and a maximum bit rate setting block. The maximum bit rate setting block is configured to: upon the light level being determined to be a low light level, set a low-light maximum bit rate; upon the light level being determined to be an intermediate light level, set an intermediate-light maximum bit rate; or upon the light level being determined to be a high light level, set a high-light maximum bit rate. The low-light maximum bit rate is lower than the intermediate-light maximum bit rate. The high-light maximum bit rate is lower than the intermediate-light maximum bit rate.

  • Patent number: 10097802
    Abstract: There is provided an image processing apparatus. A calculation unit calculates a difference in a signal level, for each area, between a first image obtained by shooting a subject under a first shooting condition and a second image obtained by shooting the subject under a second shooting condition in which high-frequency components of an optical image of the subject are reduced compared to the first shooting condition. A mixing unit mixes a signal level of the first image and a signal level of the second image at a ratio based on the difference, so as to generate a third image. The mixing unit sets a ratio of the second image when the difference is a first value, to be larger than a ratio of the second image when the difference is a second value that is smaller than the first value.

  • Patent number: 10074003
    Abstract: This application is directed to dynamic control for data capture. A device may comprise a capture logic module to receive at least one of biometric data from a biometric sensing module, context data from a context sensing module or content data from a content sensing module. The capture logic module may determine if a capture scenario exists based on at least one of the biometric data and context data. The determination may be weighted based on an operational mode. If a capture scenario is determined to exist, the capture logic module may then determine whether to capture data based on at least the content data. Captured data may be stored in a capture database in the device (e.g., along with enhanced metadata based on at least one of the biometric data, the context data or the content data). The device may also comprise a feedback database including feedback data.
