Abstract

An on-board camera system includes an imaging unit mounted in a vehicle to capture an image, a communication unit configured to perform information communication with test equipment using an OBD-II connection line; and an image compression unit configured to divide the image captured by the imaging unit into blocks with a predetermined number of pixels, to perform image compression of each image of the blocks, and to transmit the image of the blocks after image compression to the test equipment through the communication unit.

Claims

1. An on-board camera system comprising:

an imaging unit mounted in a vehicle to capture an image;

a communication unit configured to perform information communication with test equipment using an OBD-II connection line; and

an image compression unit configured to divide the image captured by the imaging unit into blocks with a predetermined number of pixels, to perform image compression of each image of the blocks, and to transmit the image of the blocks after image compression to the test equipment through the communication unit.

2. The on-board camera system according to claim 1,

wherein image compression processing by the image compression unit and compressed image transmission processing by the communication unit are performed in parallel.

3. The on-board camera system according to claim 1,

wherein the imaging unit is configured to capture an image in front of the vehicle, and

the image compression unit is configured to perform image compression of an image obtained by trimming a periphery of the front image so that at least a road surface of a lane, along which a host vehicle travels, and a portion, in which an object to be monitored is reflected, remain.

4. The on-board camera system according to claim 1,

wherein the image compression unit is configured to perform image compression using JPEG.
