  • Patent number: 10701269
    Abstract: Systems and methods are provided that capture and process frames of frame data. An image sensor captures frames of frame data representative of light incident upon the image sensor using a rolling shutter and outputs the frames of frame data. The image sensor captures at least one of the frames over a frame capture interval and then waits over a blanking interval before capturing another frame. A buffer receives and stores the frames output by the image sensor. An image signal processor retrieves the frames from the buffer and processes the frames over successive frame processing intervals to generate a video having a time interval per frame greater than the frame capture interval. At least one of the successive frame processing intervals is greater than the frame capture interval and is less than or equal to a sum of the frame capture interval and the blanking interval.

  • Patent number: 9560278
    Abstract: An imaging device includes an imaging-lens, an image-sensor, a lens-moving-mechanism, a ROM, and an intersection-point-position-control-section. The lens-moving-mechanism moves an intersection point on the image-sensor by moving a second lens in a plane perpendicular to an optical axis. The ROM stores, in advance, a LUT that stores the intersection point and an image quality evaluation value of an image, which is obtained through image capturing performed at the intersection point, in association with each other. The intersection-point-position-control-section acquires the current intersection point, calculates distances between the current intersection point and the plurality of intersection points stored in the LUT, and selects an intersection point for imaging, at which a ratio of the image quality evaluation value to the distance from the current intersection point is at the maximum, among the positions of the plurality of intersection points stored in the LUT.

  • Patent number: 9558539
    Abstract: To process image data, a distribution of gray levels of frame image data is detected. A remapping function for providing remapped gray levels is determined based on the distribution of the gray levels such that a number of the remapped gray levels is less than a number of the gray levels. Low-power frame image data are provided based on the frame image data and the remapping function such that displaying the low-power frame image data uses less power than the frame image data.

  • Patent number: 9521312
    Abstract: Signals of pixels are acquired from an image sensor in which a first pixel, a second pixel, and an imaging pixel are arranged, the first pixel receiving light flux that is restricted to light flux passing through a first portion of a pupil area of an imaging optical system, the second pixel receiving light flux that is restricted to light flux passing through a second portion that is different from the first portion of the pupil area, and the imaging pixel being different from the first and second pixels. Based on the acquired signals, estimated signals at a position at which the first and second pixel is not arranged are estimated. A defocus amount of the imaging optical system is calculated based on evaluation values obtained based on the estimated signals and the signals from the first and second pixels.

  • Patent number: 9413962
    Abstract: An amount of change between images is calculated based on a motion vector between images obtained by an image sensor and on shake information related to a shake in a rotational direction around at least an axis perpendicular to an optical axis of an imaging optical system. Then, based on a shake correction amount determined based on the shake information and the amount of change, an image obtained by the image sensor is geometrically deformed. The amount of change is a shake component of the image capture apparatus in a direction perpendicular to the optical axis, and is calculated after cancelling at least one of a change between images caused by the shake in the rotational direction included in the shake information and a change between images caused by an influence of a difference between exposure periods of the image sensor.

  • Patent number: 9350924
    Abstract: Digital imagery is composed or composited within a smartphone or other portable electronic device to merge foreground and background subject matter acquired simultaneously with different cameras or acquired at different times with the same camera. A processor stores the digital imagery along with information derived or used by an operation to differentiate the foreground subject matter from the background scene, which may be a digital matting operation, and/or may involve finding an edge or an outline of the foreground subject matter. The foreground subject matter and the background scene may be stored as different graphical layers in the memory. A user control such as a touchscreen may enable a user to select and resize or reposition the foreground subject matter on a background scene of a separately acquired image. The digital imagery may constitute a still image or a sequence of images representative of motion video.

  • Patent number: 9231009
    Abstract: In an image sensor, if a pixel for focusing has a structure having a light-shielding layer for performing pupil division, between the micro lens and the photoelectric conversion unit, the pixel may be configured such that the focal position of the micro lens is positioned further on the micro lens side than the light-shielding layer, and the distance from the focal position of the micro lens to the light-shielding layer is greater than 0 and less than nF?, where n is the refractive index at the focal position of the micro lens, F is the aperture value of the micro lens, and ? is the diffraction limit of the micro lens. This enables variation in the pupil intensity distribution of the pixel for focusing due to positional production tolerance of components to be suppressed.
