  • Patent number: 10694127
    Abstract: There is provided an image capturing apparatus. An image capturing control unit acquires a first image and a second image that require different time periods to read out electrical charge that accumulates due to exposure. A display control unit controls display of an image that is read out from an image sensor on a display unit. The second image has a lower resolution and requires a shorter time period for readout than the first image. The display control unit, when causing the display unit to cyclically display the first image and the second image, sets a first time period from readout of the second image to display start of the second image on the display unit, based on a difference between the time period to read out the first image and the time period to read out the second image.

  • Patent number: 10158797
    Abstract: For creating a single image from two images taken at different exposure setting when a face is detected, an apparatus includes an image sensor and a processor. The processor calculates a first exposure value for the photographic subject matter. Here, the first exposure value is calculated using the photographic subject matter as a whole. The processor determines whether a face is present within the photographic subject matter. In response to the determining that a face is present, the processor calculates a second exposure value. Here, the second exposure value is calculated to correctly expose the face. The processor controls the image sensor to capture a first image using the first exposure value and a second image using the second exposure value. The processor creates a third image using the first image and the second image.

  • Patent number: 10148888
    Abstract: Disclosed examples include integrated circuits, merge circuits and methods of processing multiple-exposure image data, in which a single pre-processing circuit is used for pre-processing first input exposure data associated with a first exposure of the image, and then for pre-processing second input exposure data associated with a second exposure of the image, and the first and second pre-processed exposure data are merged to generate merged image data for tone mapping and other post-processing. An example merge circuit includes a configurable gain circuit to apply a gain to the first and/or second exposure data, as well as a configurable weighting circuit with a weight calculation circuit and a motion adaptive filter circuit to compute a first and second weight values for merging the pre-processed first and second exposure data.

  • Patent number: 10104304
    Abstract: An imaging apparatus includes a acquisition unit acquires a measurement luminance, an exposure control unit, and a setting unit sets a control luminance to be used for exposure controlling in an image capturing. In an interval shooting mode, if a measurement luminance of a second image capturing to be performed after a first image capturing is in a predetermined range based on, as a reference point, a control luminance of the first image capturing, the setting unit sets a control luminance of the second image capturing to be the same as the control luminance of the first image capturing. If the measurement luminance of the second image capturing is not in the predetermined range, the setting unit sets the control luminance of the second image capturing based on a calculation result by using the measurement luminance of the second image capturing and the control luminance of the first image capturing.

    Abstract: An alignment method for high dynamic resolution imaging searches and detects features in an image and parameterizing the features. Then differently exposed images are compared by comparing the features. Additionally the method detects features in an image, performs shape adaptive filtering using scaling pyramids, determines trajectories, calculates a range of characteristics for each unit in the image, and compares characteristics of paired units to select or eliminate the pair. Paired unit characterization selects unit pairs, selects unit pairs by statistical analysis, performs cluster analysis, calculates alignment parameters, and performs additional correction of the alignment parameters.

  • Patent number: 10051213
    Abstract: A solid-state image sensor includes first and second ranging pixels that detect an incident light beam in the solid-state image sensor by separating the incident light beam in a first and second direction, respectively. The angle between the second direction and a column direction is smaller than the angle between the first direction and the column direction. A difference in exposure timings of second ranging pixels disposed in different rows is made smaller than that of first ranging pixels disposed in different rows, by causing to vary, for each row, a time over which charge is held in the in-pixel memories, in the plurality of second ranging pixels disposed in different rows.
