## Abstract

A camera image display apparatus including a display request output part outputting a display request of camera images, a power supply part supplying power to a display unit, and a power supply control unit controlling flow of electricity so as to supply activating power from the power supply part to the display unit at a first time point within a predetermined time from a completion of an engine starting, when the display request is output by the display request output part at the first time point, and to supply activating power from the power supply part to the display unit at a second time point after lapse of the predetermined time, when the display request is not output within the predetermined time from the completion of the engine starting.

## Claims

### Claim 1

A camera image display apparatus, comprising:
a display unit including a camera mounted on a vehicle to photograph surroundings of the vehicle and a monitor configured to display a camera image taken by the camera;
a display request output part configured to output a display request of the camera image;
a power supply part configured to supply an electrical power to the display unit; and
a power supply control unit configured to control a flow of an electricity from the power supply part to the display unit,
wherein the power supply control unit controls the flow of the electricity so as to supply an activating power from the power supply part to the display unit at a first time point within a predetermined time from a completion of a start of an engine mounted on the vehicle, when the display request is output at the first time point by the display request output part, and so as to supply the activating power from the power supply part to the display unit at a second time point after a lapse of the predetermined time, when the display request is not output within the predetermined time from the completion of the start of the engine.

### Claim 2 (depends on 1)

The camera image display apparatus according to claim 1, wherein
the power supply part includes a battery, and a first and second power supplies branched from the battery to output an activating signal to the display unit, and
the power supply control unit controls the flow of the electricity so as to output the activating signal from the first power supply to the display unit at the first time point, when the display request is output at the first time point by the display request output part, and so as to output the activating signal from the second power supply to the display unit at the second time point, when the display request is not output at the second time point.

### Claim 3 (depends on 2)

The camera image display apparatus according to claim 2, wherein
the power supply control unit includes a first path connected to the first power supply, a second path connected to the second power supply, and a path connecting portion configured to connect the first path and the second path, allow a flow of an electricity from the first path to the second path and prohibit a flow of an electricity from the second path to the first path, and
controls the flow of the electricity so as to output the activating signal from the first power supply to the display unit through the first path and the path connecting portion at the first time point, and output the activating signal from the second power supply to the display unit through the second path.

### Claim 4 (depends on 2)

The camera image display apparatus according to claim 2, wherein the first power supply is an ignition power supply for driving the engine and the second power supply is an accessory power supply.

### Claim 5 (depends on 2)

The camera image display apparatus according to claim 2, wherein
the power supply part further includes a third power supply branched from the battery to supply the activating power to the display unit, and
the power supply control unit controls the flow of the electricity so as to prohibit the third power supply from supplying the activating power to the display unit until the activating signal from the first power supply or the second power supply is output to the display unit, and to supply the activating power from the third power supply to the display unit, when the activating signal from the first power supply or the second power supply is output to the display unit.

### Claim 6 (depends on 5)

The camera image display apparatus according to claim 5, wherein
the power supply control unit includes a switch part operated to an off position, a first position or a second position by a driver and a switching circuit configured to switch a circuit in accordance with an operation of the switch part, and
the switching circuit switches the circuit so as to connect the battery to the third power supply when the switch part is operated to the off position, connect the battery to the first power supply, the second power supply and the third power supply when the switch part is operated to the first position, and connect the battery to the second power supply and the third power supply when the switch part is operated to the second position.

### Claim 7 (depends on 6)

The camera image display apparatus according to claim 6, wherein
the switch part is configured to further be operated to a third position for instructing the start of the engine, and
the switching circuit is switched so as to disconnect the battery and the second power supply when the switch part is operated from the second position to the third position.

### Claim 8 (depends on 1)

The camera image display apparatus according to claim 1, wherein the display unit further includes an audio device.

### Claim 9 (depends on 1)

The camera image display apparatus according to claim 1, wherein
the camera is a rear camera configured to photograph a rear of the vehicle, and
