  • Patent number: 9736458
    Abstract: A capture device is equipped with a stereo camera, and generates a plurality of demosaiced images of different sizes in which the left and right frame images have been reduced in stepwise fashion. A virtual composite image is generated that includes the plurality of demosaiced images, in which the pixel rows of the rows are pixel rows having undergone one round of connection. A host terminal sends to the capture device a data request signal designating a plurality of areas within the composite image, having a shared range in the longitudinal direction. The capture device clips out the designated areas, and sends to the host terminal a stream of a new composite image comprising only the clipped out areas. The host terminal cuts this into separate images, which are expanded into consecutive addresses in a main memory.

  • Patent number: 9717987
    Abstract: A frame storage stores an image obtained by imaging a region of at least part of the body of a user. A vital sign signal detector detects a signal sequence of a vital sign that cyclically varies from plural imaged regions of the body of the user by using captured images of a predetermined number of frames stored in the frame storage. A correlation calculator obtains the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body. An identity determining section determines whether or not the respective imaged regions of the body belong to the same user based on the correlation between the signal sequences of the vital sign detected from the respective imaged regions of the body.

  • Patent number: 9710923
    Abstract: An imaging device 12 includes a first camera 22 and a second camera 24. Each of the cameras captures a subject from left and right positions that are apart by a known width at the same timing and frame rate. Each of the captured frame images is converted into image data with a plurality of predetermined resolutions. An input information acquisition section 26 of an information processor 14 acquires an instruction input from the user. A position information generation section 28 roughly estimates, as a target area, a subject area or an area with motion using low-resolution and wide-range images of pieces of stereo image data and performs stereo matching using high-resolution images only for the area, thus identifying the three-dimensional position of the subject. An output information generation section 32 performs a necessary process based on the position of the subject, thus generating output information. A communication section 30 requests image data to the imaging device 12 and acquires such image data.

  • Patent number: 9699432
    Abstract: An image pickup apparatus 12 includes a first camera 22 and a second camera 24. The cameras pick up an image of a target at the same timing and at the same frame rate from left and right positions spaced by a known distance from each other. Picked up frame images are converted into image data of a predetermined plurality of resolutions. An input information acquisition section 26 of an information processing apparatus 14 acquires an instruction input from a user. A position information production section 28 approximately estimates a region of the target or a region which involves some movement on an image of a low resolution and a wide range from within stereo image data as a target region and carries out stereo matching only in regard to the region on an image of a high resolution to specify a three-dimensional position of the target. An output information production section 32 carries out a necessary process based on the position of the target to produce output information.

  • Patent number: 9693072
    Abstract: A frame sequence of moving picture data is divided into a tile image sequence, and the color space of the tile image sequence is converted to generate a YCbCr image sequence. Each frame is reduced to ½ time in the vertical and horizontal directions, and a compression process is carried out to generate compression data of a reference image. The compression data of the reference image is decoded and decompressed similarly as upon image display to restore a YCbCr image as the reference image, and a difference image sequence is generated from the reference image and the original YCbCr image. Then, compression data of a difference image is generated, and compression data obtained by connecting the compression data of the reference image and the compression data of the difference image is generated for every four frames of a tile image.

  • Publication number: 20170109864
    Abstract: An imaging apparatus 12 acquires RAW images 202a and 202b by left and right cameras and performs a demosaicing process for and stepwise reduction of the RAW images 202a and 202b to generate and correct colored image groups 204a and 204b which represent picked up images with a plurality of resolutions (S10 and S12). Image process parameters 206 acquired in the course of the demosaicing process and the correction process are transmitted to a host terminal 20 together with part of colored images and data of a partial image 208 of the RAW image 202a. The host terminal 20 utilizes the image process parameters 206 transmitted from the imaging apparatus 12 to perform a demosaicing process for the partial image 208 to generate and correct a colored image 212 (S16). The host terminal 20 utilizes the colored image transmitted from the imaging apparatus 12 and the colored image 212 generated therein to generate an image 214 to be displayed (S18 and S20).

  • 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.
