Abstract

A display control device includes: an image acquisition unit acquiring a plurality of captured image data in a time series of output from an imagining unit imaging a periphery of a vehicle; an object detection unit detecting an object with respect to each of the plurality of captured image data; a movement calculation unit calculating a movement direction and speed of the object; a display information determination unit determining a position of display information corresponding to the object, displayed on a display area of second captured image data output from the imagining unit after the plurality of captured image data, based on the movement direction and speed; and a display controller causing a display unit to display the second captured image data, and to superimpose and display the display information on the display area based on the determined position.

Claims

1. A display control device comprising:

an image acquisition unit that acquires a plurality of captured image data in a time series of output from an imagining unit that images a periphery of a vehicle;

an object detection unit that detects an object with respect to each of the plurality of captured image data;

a movement calculation unit that calculates a movement direction and a movement speed of the object;

a display information determination unit that determines a position of display information corresponding to the object, which is displayed on a display area of second captured image data output from the imagining unit after the plurality of captured image data, based on the movement direction and the movement speed; and

a display controller that causes a display unit to display the second captured image data, and to superimpose and display the display information on the display area based on the determined position.

2. The display control device according to claim 1,

wherein the movement calculation unit calculates the movement direction and the movement speed of the object in the display area from a movement of the object in the display area based on the plurality of captured image data.

3. The display control device according to claim 1,

wherein the movement calculation unit calculates the movement direction and the movement speed of the object from a movement of the object in a three-dimensional coordinate space that displays a relative positional relationship between the vehicle and the object based on the plurality of captured image data.

4. The display control device according to claim 1,

wherein the display information determination unit determines the position of the display information based on the movement direction, the movement speed, and a processing time required to determine the position of the display information from the plurality of captured image data.

5. The display control device according to claim 1,

wherein the display information is a frame surrounding the object,

the display information determination unit determines a position and a size of the frame corresponding to the object in the display area of the second captured image data based on the movement direction and the movement speed, and

the display controller causes the display unit to display the second captured image data and to superimpose and display the frame on the display area based on the determined position and size.
