  • Patent number: 11025853
    Abstract: The present technology relates to a comparator circuit, a solid-state imaging apparatus, and an electronic device which enable to improve a frame rate. A comparator compares an analog signal with a reference signal, an amplification stage amplifies output of a comparing unit and has different output change speeds in normal rotation and in reverse rotation, and a switch circuit fixes an input node or an output node of the amplification stage to a predetermined voltage in a predetermined period before a comparing operation by the comparator so that the amplification stage operates in a change direction having a higher output change speed. The present technology can be applied to a comparator circuit provided to an A/D converter of a CMOS image sensor.

  • Patent number: 10939062
    Abstract: The present disclosure relates to a solid-state imaging apparatus and electronic equipment that can reduce power consumption. In an AD converter for each unit pixel or each shared pixel unit, a pixel signal is compared with a reference signal temporally changing. In addition, a magnitude of a pixel signal of a pixel of interest is compared with a magnitude of each of pixel signals of neighboring pixels located in a neighborhood of the pixel of interest using the reference signal, and a result of comparison of the magnitudes is held in a data storage section. The present disclosure can be applied to a back-illuminated solid-state imaging apparatus, for example.

  • Patent number: 10935390
    Abstract: A communication terminal is connected to a server and transmits a route search request for a destination to the server and obtains a route searched for from the server according to the request. When setting a destination or transmitting the route search request to the server, the terminal requests the server for guidance information targeted for at least an update target area around a current location among update target areas. The guidance information is for providing movement guidance for a mobile unit, and the update target areas are areas whose terminal-side map information included in the terminal is an older version of map information relative to the server's device-side map information. The terminal receives the guidance information transmitted from the server according to the request for the guidance information, and provides the movement guidance for the mobile unit using a route set on the terminal and the received guidance information.

  • Patent number: 10861332
    Abstract: A communication terminal is connected to a server device in a bidirectionally communicable manner and configured to transmit a departure point, a destination, and a route retrieval request from the departure point to the destination to the server device and to acquire a route that is retrieved and delivered by the server device in response to the route retrieval request. The communication terminal receives, from the server device, location road information for identifying a position of a moving object on a map and identifying the position of the moving object based on the received location road information. The communication terminal transmits, to the server device, the route retrieval request in which the identified position of the moving object is set as the departure point, and receives, from the server device, a route that is retrieved by the server device in response to the route retrieval request.
