## Abstract

A video processing circuit outputs a video signal from an imaging device for imaging a scene outside a vehicle to a display unit. A main processing circuit generates an image from vehicle information and outputs the image to the video processing circuit, a starting time of the main processing circuit being longer than that of the video processing circuit. The video processing circuit superimposes the image from the main processing circuit on the video signal from the imaging device and outputs a resultant video to the display unit.

## Claims

### Claim 1

A vehicle-mounted device comprising:
a video processing circuit that outputs a video signal from an imaging device for imaging a scene outside a vehicle to a display unit; and
a main processing circuit that generates an image from vehicle information and outputs the image to the video processing circuit, a starting time of the main processing circuit being longer than that of the video processing circuit, wherein
the video processing circuit superimposes the image from the main processing circuit on the video signal from the imaging device and outputs a resultant video to the display unit.

### Claim 2 (depends on 1)

The vehicle-mounted device according to claim 1, wherein
the main processing circuit generates the image in units of frames, and
the video processing circuit blends the image from the main processing circuit with the video signal from the imaging device.

### Claim 3 (depends on 1)

The vehicle-mounted device according to claim 1, wherein
the main processing circuit outputs a video signal in which each pixel in the image is defined by a red component, a green component, a blue component, and a transparency to the video processing circuit.

### Claim 4 (depends on 1)

The vehicle-mounted device according to claim 1, wherein
the main processing circuit is capable of outputting a video signal from a source other than the imaging device to the video processing circuit,
the main processing circuit outputs an instruction signal for setting an image blending function to be on or off to the video processing circuit, and
in a case of outputting the video signal from a source other than the imaging device to the video processing circuit, the main processing circuit outputs an instruction signal for setting the image blending function to be off.

### Claim 5 (depends on 4)

The vehicle-mounted device according to claim 4, wherein
in a case of outputting a video signal from a source other than the imaging device to the video processing circuit, the main processing circuit outputs a video signal in which each pixel is defined by a red component, a green component, and a blue component,
in a case of outputting the image to the video processing circuit, the main processing circuit outputs a video signal in which each pixel is defined by a red component, a green component, a blue component, and a transparency, and
a number of bits defining each pixel in the video signal output from the main processing circuit to the video processing circuit remains the same regardless of whether the video signal from a source other than the imaging device is output or the image is output.

### Claim 6 (depends on 1)

The vehicle-mounted device according to claim 1, wherein
the imaging device is a device for imaging a scene behind the vehicle.
