Abstract
A video signal processing device, which includes: a plurality of imaging devices outputting mutually asynchronous interlace video signals; input buffers temporarily storing field by field the video signals outputted from the respective imaging devices; and an output image generating device generating field by field video signals of output target images from the video signals stored in the input buffers, wherein each of the video signals of the output target images is generated when all of the latest video signals to be components thereof are stored in the input buffers.
Claims9
A video signal processing device, comprising:
- a plurality of imaging devices outputting mutually asynchronous interlace video signals;
- input buffers temporarily storing field by field the video signals outputted from the respective imaging devices;
- and
- an output image generating device generating field by field video signals of output target images from the video signals stored in the input buffers, wherein each of the video signals of the output target images is generated when all of the latest video signals to be components thereof are stored in the input buffers.
A method for video signal processing, comprising:
- temporarily storing field by field mutually asynchronous interlace video signals outputted from a plurality of imaging devices in input buffers;
- and
- generating field by field video signals of output target images from the video signals stored in the input buffers, generating each of the video signals of the output target images when all of the latest video signals to be components thereof are stored in the input buffers.
A vehicle-mounted camera system, comprising:
- a plurality of imaging devices imaging areas around a vehicle and outputting mutually asynchronous interlace video signals;
- input buffers temporarily storing field by field the video signals outputted from the respective imaging devices;
- an output image generating device generating field by field video signals of output target images from the video signals stored in the input buffers, wherein each of the video signals of the output target images is generated when all of the latest video signals to be components thereof are stored in the input buffers;
- an output buffer storing field by field the generated video signals of the output target images;
- and
- a display device displaying the video signals stored in the output buffer to a driver of the vehicle.
