  • Patent number: 9619868
    Abstract: An imaging device includes a first camera and a second camera and shoots the same object under different shooting conditions. A shot-image data acquirer of an image analyzer acquires data of two images simultaneously shot from the imaging device. A correcting section aligns the distributions of the luminance value between the two images by carrying out correction for either one of the two images. A correction table managing section switches and generates a correction table to be used according to the function implemented by the information processing device. A correction table storage stores the correction table showing the correspondence relationship between the luminance values before and after correction. A depth image generator performs stereo matching by using the two images and generates a depth image.

  • Publication number: 20170094163
    Abstract: An image pickup apparatus includes an image data production unit which produces data of images of a plurality of resolutions, from an image frame obtained by picking up an image of a target object as a moving picture for each pixel string which configures a row, and an image sending unit which extracts, from the data of the images of the plurality of resolutions, pixel strings of a region requested from a host terminal and connect the extracted pixel strings for each number of pixels determined in accordance with a given rule to produce a stream and then transmit the stream to the host terminal. The image sending unit adjusts a connection pixel number of data of an image of a particular resolution such that, where N is an integer, data for 1/(N+1) frame are transmitted with respect to one frame of data of an image of the other resolution.

  • Publication number: 20170011519
    Abstract: A detection area 112 is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area 112, coordinate points (white and black dots) represented by pixels making up a silhouette 114 of the hand in a depth image enter the detection area 112. In the detection area 112, a reference vector 126 is set that shows the direction which the hand should face relative to the shoulder as a reference point 122. Then, an inner product between two vectors, a vector from the reference point 122 to each of coordinate points and the reference vector 126, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.
