Problems solved by technology
[0005] However, in the conventionally proposed technology, there is a problem that since complex processing of setting a virtual angle of view based on the detected position of the object and the position of the vehicle is required, the processing load is heavy, and it takes time, for example, to generate an angle-of-view converted image. , which in turn has concerns about compromising the real-time performance associated with driver assistance

[0026] figure 1 The illustrated vehicle-mounted display control device 1 includes a plurality of cameras 10 , a display control unit 20 , and a display 30 . In addition, although not shown, the in-vehicle display control device 1 is configured to be connected to an in-vehicle local area network (hereinafter referred to as "in-vehicle LAN"), and to communicate with other electronic control units (hereinafter referred to as "in-vehicle LAN") connected to the in-vehicle LAN. Vehicle information such as detection information of various sensors is shared among ECUs). In the following description, a vehicle equipped with these components is referred to as an own vehicle.
[0027] In addition, in this embodiment, the display control unit 20 is a processing device that processes image data captured by a plurality of cameras 10 (described later).
[0028] In addition, the in-vehicle LAN is a local area network provided inside the vehicle. For example, using the well-known CAN (Contr...

An on-vehicle display control device (1) is provided with: an image recognition unit (21); a viewpoint conversion unit (22); an image emphasizing unit (25); and an image output unit (26). The image recognition unit (21) recognizes objects within captured images of a plurality of imaging devices mounted to a vehicle so as to respectively image each of a plurality of imaging regions around the periphery of the vehicle. The viewpoint conversion unit (22) specifies, as a recognition imaging device, an imaging device among the plurality of imaging devices which has captured an image including an object recognized by the image recognition unit, and converts the captured image into a converted viewpoint image viewed from a virtual view point associated with the specified recognition imaging device. The image emphasizing unit (25) emphasizes an object image section included in the converted viewpoint image converted by the viewpoint conversion unit (22). The converted viewpoint image in whichthe object image section has been emphasized by the image emphasizing unit (25) is set as a driving assistance image, and the driving assistance image is outputted from the image output unit to a display device.
Description
technical field [0001] The present invention relates to a display control technology for providing driving assistance images to a driver of a vehicle, and particularly relates to mounting a plurality of imaging devices so as to capture images of respective imaging areas around the vehicle, and providing driving information based on image data from these plurality of imaging devices. Auxiliary image display control technology. Background technique [0002] In conventional in-vehicle display control, it is known to detect an object around the vehicle with an on-vehicle camera, convert the captured image including the object into an image viewed from a virtual angle of view, and output the angle-of-view converted image to the in-vehicle display as a driving assistance image. technology. [0003] For example, in this technique, it is proposed to detect the position of an approaching vehicle approaching the host vehicle from behind the host vehicle, to increase the height of the...
