Display control device
A display control device includes: a reception unit that receives an input for designating a first point on a first image, which is displayed on a display screen provided in a vehicle compartment and shows a peripheral environment of a vehicle at a first timing; a display processing unit that displays a first display object at the first point; a specifying unit that specifies a second point at which a first target, which is located at the first point, is located on a second image, which shows the peripheral environment of the vehicle at a second timing after the first timing; and an update unit that displays, along with the second image, the first display object at the second point on the second image.
1. A display control device comprising:
a processor configured to implement:
a reception unit that receives at least two points for designating two first points on a first image, wherein the two first points are located at two first targets respectively, which are displayed on a display screen provided in a vehicle compartment and shows a peripheral environment of a vehicle, the first image being acquired by a peripheral information acquiring device at a first timing;
a display processing unit that displays a first display object being a line that interconnects the two first points;
a specifying unit that specifies at least two second points at which the two first targets are located on a second image, which shows the peripheral environment of the vehicle, the second image being acquired by the peripheral information acquiring device at a second timing after the first timing; and
an update unit that displays, along with the second image, the first display object as a line that interconnects the two second points on the second image.
2. The display control device according to claim 1 ,
wherein the peripheral information acquiring device comprises a plurality of imaging devices,
the first image is captured by a first imaging device, from among the plurality of imaging devices, which is provided in the vehicle and faces a first direction, and
the second image is captured by a second imaging device, from among the plurality of imaging devices, which is provided in the vehicle and faces a second direction, which is different from the first direction.
3. The display control device according to claim 1 ,
wherein the peripheral information acquiring device is provided in the vehicle,
the second image shows an area under a floor of the vehicle, and
the display processing unit produces the second image from a fifth image, which is acquired by the peripheral information acquiring device at a fifth timing before the second timing.
4. The display control device according to claim 1 ,
wherein the reception unit receives a trace that has one of the at least two points as a start point and another of the at least two points as an end point and passes through a point when a user slides a finger on the display screen, and
the display processing unit displays the first display object being the line based on the trace.
5. The display control device according to claim 1 ,
wherein the update unit deletes the first display object based on moving state of the vehicle.
6. The display control device according to claim 3 ,
wherein the fifth timing is a timing when the peripheral information acquiring device acquired the fifth image that shows a road surface under a floor of the vehicle at the second timing.
7. A display control method comprising:
acquiring a first image at a first timing, wherein the first image shows a peripheral environment of a vehicle;
displaying, on a display screen, the first image, wherein the display screen is provided in a vehicle compartment;
receiving at least two points for designating two first points on the first image, wherein the two first points are located at two first targets respectively;
displaying, on the display screen, a first display object, wherein the first display object is a line that interconnects the two first points;
acquiring a second image at a second timing, wherein the second image shows the peripheral environment of the vehicle and wherein the second timing is after the first timing;
specifying at least two second points at which the two first targets are located on the second image; and
displaying, on the display screen, along with the second image, the first display object as a line that interconnects the two second points on the second image.
8. A display control device comprising:
a reception means for receiving at least two points for designating two first points on a first image, wherein the two first points are located at two first targets respectively, which are displayed on a display screen provided in a vehicle compartment and shows a peripheral environment of a vehicle, the first image being acquired by a peripheral information acquiring device at a first timing;
a display processing means for displaying a first display object being a line that interconnects the two first points;
a specifying means for specifying at least two second points at which the two first targets are located on a second image, which shows the peripheral environment of the vehicle, the second image being acquired by the peripheral information acquiring device at a second timing after the first timing; and
an update means for displaying, along with the second image, the first display object as a line that interconnects the two second points on the second image.
