Automobile camera module and method to indicate moving guide line
First Claim
1. An automobile camera module comprising:
- a memory to store guide line images for vehicle traveling traces divided according to a steering angle of the vehicle'"'"'s handle;
an image sensor to photograph a front image or a rear image, and generating an image signal for an image obtained by overlapping the guide line image stored in the memory with the photographed image;
a controller (CAN MCU) to receive steering angle information of the vehicle'"'"'s handle, extracting a guide line image corresponding to the steering angle from the guide line images, and to control the image sensor to perform image overlap; and
an image output amp to convert a signal of the image overlapped in the image sensor into an output signal, and transmit the converted signal to an image display unit through a serial bus network.

Abstract
The present invention relates to a camera module and a method to indicate a moving guide line using the same. The camera module includes a memory for storing guide line images for vehicle traveling traces divided according to a steering angle of the vehicle'"'"'s handle; an image sensor for photographing a front image or a rear image, and generating an image signal for an image obtained by overlapping the guide line image stored in the memory with the photographed image; a controller (CAN MCU) for receiving steering angle information of the vehicle'"'"'s handle, extracting a guide line image corresponding to the steering angle from the guide line images, and controlling the image sensor to perform image overlapping; and an image output amp for converting a signal of the image overlapped in the image sensor into an output signal, and transmitting the converted signal to an image display unit through a serial bus network.

10. A method to indicate a moving guide line comprising:
-
photographing an external image of a vehicle through a camera module mounted on the front or the rear of the vehicle; receiving, by a controller, a steering signal for a steering angle of the vehicle'"'"'s handle through a communication unit connected to the camera module; selecting a guide line image corresponding to the steering signal from a plurality of guide line images, stored in a memory within the camera module, based on steering angle information of the vehicle'"'"'s handle received to the controller; transmitting the guide line image selected by the controller to an image sensor within the camera module, and then overlapping the transmitted guide line image with the external image photographed by the image sensor; and converting the image, obtained by overlapping the external image with the guide line image, into an image signal, and then outputting the image signal to the image display unit connected to the camera module, through an image output amp connected to the image sensor. - View Dependent Claims (11, 12, 13, 14)
