  • Patent number: 9661302
    Abstract: A depth information acquisition apparatus acquires depth information of a subject by using two real space images, each having a different blur value, that are obtained by capturing a subject with different imaging parameters. A processor and a memory store instructions that cause the processor to perform converting the two real space images into two frequency space images, each having a frequency including at least one frequency ingredient and an amplitude. A frequency space phase image is generated for each of the frequency space images by dividing each frequency ingredient by the amplitude of each respective frequency space image using a frequency. Frequency space correlation value information representing a correlation value for each frequency between the frequencies of the two frequency space phase images is calculated. The frequency space correlation value information is converted into real space correlation value information having a peak maximum value.

  • Patent number: 9576370
    Abstract: A distance measurement method for calculating distance information from a first image and a second image that are image-captured with different image-capturing parameters. A setting step sets a first local region located in the first image including a distance calculation target pixel, and a second local region located in the second image corresponding to the first local region. An extraction step extracts a plurality of shift regions, which are regions of which a shift amount from the second local region is within a predetermined range. A correlation value is calculated between the first local region and each of the plurality of shift regions. A decision step determines a correlation value used for calculating distance information, based on the plurality of correlation values calculated in the first calculation step. The distance information on the distance calculation target pixel is calculated, based on the correlation value determined in the decision step.
