  • Publication number: 20140369618
    Abstract: According to an embodiment, an encoding device includes an area setting unit, a parameter controller, and an encoder. The area setting unit is configured to, in an image captured by an imager mounted on a vehicle while the vehicle is moving along a predetermined route, set a boundary in the image at a predetermined distance from the imager, a first area being an area inside of the boundary, and a second area being an area outside of the boundary. The parameter controller is configured to control an encoding parameter to assign a larger code amount to the first area than to the second area. The encoder is configured to encode the image in accordance with the encoding parameter.
