Abstract: The present disclosure relates to an image reading device having a highly-accurate structure that enables an easy increase in depth of field, that is, improvement in the depth of the field, without need for a change in basic characteristics of lenses. An overlap preventer (5) disposed between a lens array (1) and a sensor element array (3) to prevent overlap of images formed by lenses (2) is included. A slit section (5) that is the overlap preventer (5) includes multiple slit plates (7) arranged in a main scanning direction and extending in a sub-scanning direction to partition off a space, and the slit plates (7) are fixed to fixing plates (13).

Abstract: According to an embodiment, a client includes a street information collection unit for collecting street information near an arrangement place, a provision determination unit for determining whether the street information collected by the street information collection unit is information required to be provided to the server, and a first transmission unit for transmitting the street information, which is determined to be required to be provided by determination of the provision determination unit, to the server, with client identification information for identifying the client.

Abstract: According to an embodiment, a smart camera includes an image sensor, an encoder, a feature data generator, a synchronizer, a multiplexer, and a transmitter. The image sensor outputs a video signal. The encoder encodes the video signal to generate video data. The feature data generator generates feature data of the video signal. The synchronizer synchronizes the generated feature data with the video data. The multiplexer multiplexes the video data and the feature data synchronized with the video data into a transport stream. The transmitter transmits the transport stream to a communication network.
