Abstract

A display control apparatus includes a captured data acquisition unit, a motion state detection unit, an extracted image data generation unit, a display image data generation unit, and an output unit. The captured data acquisition unit is configured to acquire captured data generated as a result of a camera capturing scenery outside a vehicle. The motion state detection unit is configured to detect a motion state of the vehicle. The extracted image data generation unit is configured to generate an extracted image from the captured data by using an angle of view set in accordance with the motion state. The display image data generation unit is configured to generate display image data related to a display image having a preset image size, from extracted image data. The output unit is configured to output the display image to a display unit having the image size.

First claim

What is claimed is:

1. A display control apparatus comprising:
a first camera configured to capture scenery outside a vehicle;
a second camera configured to capture scenery outside the vehicle;
a processor coupled to a memory storing instructions to permit the processor to function as:
a captured data acquisition unit configured to acquire a first captured data obtained by the first camera capturing scenery outside the vehicle and the second captured data obtained by the second camera capturing scenery outside the vehicle;
a motion state detection unit configured to detect a motion state of the vehicle;
an extracted image data generation unit configured to generate a first extracted image data relevant to the scenery on a side of a first direction with respect to the vehicle from an image related to the first captured data and a second extracted image data relevant to the scenery on a side of a second direction with respect to the vehicle from an image related to the second captured data by using an angle of view set in accordance with the motion state;
a size assignment unit configured to, upon detection of the motion state, assign an image size of a display image corresponding to each of pieces of extracted image data, so as to be fitted to a total image size of a display unit, wherein the size assignment unit determines, for the first extracted image data extracted from the first capturing image data and the second extracted image data extracted from the second capturing image data, an image size of a display image corresponding to the second extracted image data, based on magnitude of an angle of view corresponding to the first extracted image data;
a display image data generation unit configured to generate display image data related to a display image using information of the image size determined by the size assignment unit; and
an output unit configured to output the display image data to the display unit having the image size.

2. The display control apparatus according to claim 1 , wherein the processor is further configured to functions as a vehicle information acquisition unit configured to acquire vehicle information related to a driven state of the vehicle, wherein
the motion state detection unit detects the motion state based on the vehicle information.

3. The display control apparatus according to claim 1 , wherein
the motion state detection unit detects a traveling speed of the vehicle, and
the extracted image data generation unit generates the first and second extracted image data in which a first angle of view corresponding to the traveling speed at a first speed is set to be narrower than a second angle of view corresponding to a second speed lower than the first speed.

4. The display control apparatus according to claim 3 , wherein, when the extracted image data generation unit has generated the first and second extracted image data set with the second angle of view, the display image data generation unit generates the display image data by shrinking an image related to the first and second extracted image data along a prescribed direction to convert the image size of the image to the image size that the display unit has.

5. The display control apparatus according to claim 1 , wherein
with respect to each of the pieces of extracted image data, the display image data generation unit generates the display image data fitted to the assigned image size.

6. The display control apparatus according to claim 1 , wherein
the motion state includes a change in a traveling direction of the vehicle, and
in response to the traveling direction being changed to the first direction, the size assignment unit assigns the image sizes so that a dimension in a primary direction of a display image corresponding to the first extracted image data is larger than a dimension in the primary direction of a display image corresponding to the second extracted image data.

7. The display control apparatus according to claim 1 , wherein the processor is further configured to functions as an index image data generation unit configured to generate index image data for expressing distortion of the display image.

8. The display control apparatus according to claim 1 , wherein a third camera is configured to capture scenery outside the vehicle,
wherein third captured data obtained by the third camera capturing scenery outside the vehicle;
wherein third extracted image data relevant to the scenery on a side of a third direction with respect to the vehicle is generated from an image related to the third captured data by using the angle of view set in accordance with the motion state,
wherein, upon detection of the motion state, the image size of the display image corresponding to the first extracted image data, the second extracted image data, and the third extracted image data is assigned so as to be fitted to the total image size of the display unit, and
wherein an image size of the display image corresponding to the third extracted image data is determined based on the magnitude of the angle of view corresponding to the first extracted image data and a magnitude of an angle of view corresponding to the second extracted image data.

9. A display control method comprising:
a captured data acquisition step of acquiring first captured data obtained by a first camera capturing scenery outside a vehicle and second captured data obtained by a second camera capturing scenery outside the vehicle;
a motion state detection step of detecting a motion state of the vehicle;
an extracted image data generation step of generating a first extracted image data relevant to the scenery on a side of a first direction with respect to the vehicle from an image related to the first captured data and a second extracted image data relevant to the scenery on a side of a second direction with respect to the vehicle from an image related to the second captured data by using an angle of view set in accordance with the motion state;
a size assignment step of assigning, upon detection of the motion state, an image size of a display image corresponding to each of pieces of extracted image data, so as to be fitted to a total image size of a display unit, the size assignment step comprising determining, for the first extracted image data extracted from the first captured data and the second extracted image data extracted from the second captured data, an image size of a display image corresponding to the second extracted image data, based on magnitude of an angle of view corresponding to the first extracted image data;
a display image data generation step of generating display image data related to a display image using information of the image size determined at the size assignment step; and
an output step of outputting the display image data to the display unit having the image size.

10. A non-transitory computer-readable medium that stores a program for causing a computer to implement a display control method comprising:
a captured data acquisition step of acquiring first captured data obtained by a first camera capturing scenery outside a vehicle and second captured data obtained by a second camera capturing scenery outside the vehicle;
a motion state detection step of detecting a motion state of the vehicle;
an extracted image data generation step of generating first extracted image data relevant to the scenery on a side of a first direction with respect to the vehicle from an image related to the first captured data and a second extracted image data relevant to the scenery on a side of a second direction with respect to the vehicle from an image related to the second captured data by using an angle of view set in accordance with the motion
