Abstract

A vehicular surrounding-monitoring control apparatus is mounted in a vehicle having an imaging unit capturing an image of surrounding and a display. The vehicular surrounding-monitoring control apparatus includes: an extraction section extracting, as an object region, an image region corresponding to each object from a captured image obtained by the imaging unit; a determining section determining whether a plurality of objects are coordinated into a group on the basis of positional relations of the object regions and types of the objects; and a display control unit displaying, when the objects are determined to be coordinated into a group, displaying a symbol image, which is specific to the group and expresses the presence of the group, so as to be superimposed on the captured image in the display.

First claim

The invention claimed is:

1. A vehicular surrounding-monitoring control apparatus in a vehicle having an imaging unit that captures an image of surrounding of the vehicle and a first display, the apparatus comprising:
an extraction section extracting, as an object region, an image region corresponding to each object from a captured image obtained by the imaging unit;
a determination section determining, when a plurality of object regions corresponding to a plurality of objects are extracted by the extraction section, whether the objects are coordinated into a group or not, based on types of the objects and positional relations between the object regions; and
a display control unit displaying, when the objects are determined to be coordinated into the group, a symbol image that is specific to the group to be superimposed on the captured image in the first display, the symbol image expressing a presence of the group.

2. The vehicular surrounding-monitoring control apparatus according to claim 1 , further comprising:
a type determination section determining type of the object or the group,
wherein the type is reflected in the symbol image.

3. The vehicular surrounding-monitoring control apparatus according to claim 1 , wherein
when, of the object regions, a first object region overlaps a second object region that is different from the first object region, the determination section determines that the objects are coordinated into the group.

4. The vehicular surrounding-monitoring control apparatus according to claim 1 , wherein
when interval between, of the object regions, a first object region and a second object region that is different from the first object region is lower than a predetermined threshold, the determination section determines that the objects are coordinated into the group.

5. The vehicular surrounding-monitoring control apparatus according to claim 4 , wherein the threshold is determined according to size of the object region.

6. The vehicular surrounding-monitoring control apparatus according to claim 1 , further comprising:
a visibility determination section determining visibility specific to the group,
wherein when the visibility exceeds a predetermined state, the display control unit restricts the displaying of the symbol image specific to the group.

7. The vehicular surrounding-monitoring control apparatus according to claim 1 , wherein
the display control unit displays the symbol image to blink in a predetermined display cycle.

8. The vehicular surrounding-monitoring control apparatus according to claim 7 , further comprising:
an occupancy calculation section calculating occupancy of a display region of the symbol image displayed, in an entire display region of the first display,
wherein the display cycle is set according to the occupancy.

9. The vehicular surrounding-monitoring control apparatus according to claim 1 , further comprising:
an occupancy calculation section calculating occupancy of a display region of the symbol image displayed, in an entire display region of the first display,
when the occupancy exceeds a predetermined occupancy threshold, the display control unit displays the symbol image in a second display that is additionally included in the vehicle to be independent of the first display.
