  • Publication number: 20240145496
    Abstract: Imaging devices and ranging devices are disclosed. In one example, an imaging device includes a semiconductor substrate, a first pixel array, a second pixel array, and a control unit. In the first pixel array, a first light receiving pixel on the semiconductor substrate has a stacked structure of a first electrode, a photoelectric conversion layer, and a second electrode (80). It photoelectrically converts light in a first wavelength region including the visible light region. In the second pixel array, a second light receiving pixel is provided at a position overlapping the first light receiving pixel in a thickness direction of the semiconductor substrate. It photoelectrically converts light in a second wavelength region including the infrared light region. The control unit drives and controls the second pixel array based on a signal photoelectrically converted by the first pixel array.

  • Publication number: 20240120605
    Abstract: A partition member, which separates objects to be separated from each other, includes a porous sheet, and a water absorbing material provided at least either on a surface of the porous sheet or inside the porous sheet. The partition member that has dimensions of 100 mm×60 mm and has been stored for 24 hours at a temperature of 25° C., a humidity of 40%, and an atmospheric pressure of 1 atm is used as a sample, and a ratio of a water absorption volume when a portion of 10 mm from an lower end of a 60 mm side of the sample is immersed in water for 2 minutes, to a volume of the sample {the water absorption volume (cm3) divided by a volume (cm3) of the partition member} is in a range of 0.1 to 0.9.

  • Patent number: 9092908
    Abstract: Embodiments of the invention include a system, method and computer-readable medium for viewing images in a three-dimensional environment. A user is identified. A social graph of the identified user and a plurality of other users is accessed. Based on the social graph, a plurality of images associated with one or more of the other users in the social graph are determined. The plurality of images and data are provided to a client device, wherein the data enables the display of the images in the 3D environment, at the client device.

  • Publication number: 20140297575
    Abstract: Systems and methods of the present disclosure provide techniques for providing user-specified ways of navigating through real-world three-dimensional geographic imagery that spans space and time. An exemplary method includes identifying a plurality of images depicting a geographic location at street level. The images are captured at the geographic location over a span of time. Using a processor, image data is associated with the plurality of images. The image data includes information representing positional data and a time dimension related to the plurality of images. Using the processor, a user's navigational intent to move back and forward through the time dimension is predicted based on a navigational signal. The exemplary method further includes selecting a set of images from the plurality of images based on the image data and the predicted navigational intent. The set of images depict conditions at the geolocation for one or more time periods.
