Vehicle-onboard driving lane recognizing apparatus
First Claim
1. A vehicle-onboard driving lane recognizing apparatus, comprising:
- image pick-up means mounted on a motor vehicle running on a road for picking up images of scenes making appearance in front of said motor vehicle;
image data selecting means for selecting image data only of a predetermined region from the image picked up by said image pick-up means;
image data storing means for storing said image data; and
driving lane recognizing means for detecting lane markings on said road from the image data stored in said image data storing means to thereby recognize a driving lane extending along said lane markings, wherein at least said image data selecting means, said image data storing means and said driving lane recognizing means are all implemented in a single chip.

Abstract
A vehicle-onboard driving lane recognizing apparatus of a small scale includes an image pick-up unit (1) mounted on a motor vehicle for picking up images of scenes making appearance in front of the motor vehicle, an image data selecting unit (2) for selecting image data only of a predetermined region from the image picked up by the image pick-up unit (1), an image data storing unit (3) for storing the image data, and a driving lane recognizing unit (4) for detecting lane markings (21) on the road from the image data stored in the image data storing unit (3) to thereby recognize a driving lane extending along the lane markings (21). The image data selecting unit (2), the image data storing unit (3) and the driving lane recognizing unit (4) are all implemented in a single chip.

6. A vehicle-onboard driving lane recognizing apparatus, comprising:
-
image pick-up means mounted on a motor vehicle running on a road for picking up images of scenes making appearance in front of said motor vehicle to thereby output picked-up images in the form of pixel data;
image data transfer rate converting means for converting transfer rate of said pixel data for transferring said pixel data at a converted transfer rate;
image data selecting means for selecting the image data of a predetermined region from image data constituted by a set of said pixel data outputted from said pixel data transfer rate converting means;
image data storing means for storing the image data selected by said image data selecting means; and
driving lane recognizing means for detecting lane markings on said road from the image data stored in said image data storing means to thereby recognize a driving lane extending along said lane markings, wherein representing the number of said pixel data by M while representing the number of bits of said pixel data by N (where M and N are given natural numbers, respectively), said pixel data transfer rate converting means is so arranged as to transform M pixel data each of N bits into a single (M×
N)-bit data for thereby transferring said (M×
N)-bit data to said image data selecting means en bloc through a single transfer at a time point when M pixel data each of N bits have been held. - View Dependent Claims (7, 8, 9, 10)

11. A vehicle-onboard driving lane recognizing apparatus, comprising:
-
image pick-up means mounted on a motor vehicle running on a road for picking up images of scenes making appearance in front of said motor vehicle;
image input/output interface means for selecting one of input from said image pick-up means and input from an external system for outputting the selected image data;
image data selecting means for selecting image data of only a predetermined region from said image data;
image data storing means for storing the image data selected by said image data selecting means; and
driving lane recognizing means for detecting lane markings on said road from the image data stored in said image data storing means to thereby recognize a driving lane extending along said lane markings, wherein said image input/output interface means is so arranged that when it is decided that the image data originating in said external system is inputted, said image input/output interface means selects said external system as an input source to thereby allow said image data supplied from said input source to be outputted to said image data selecting means and said external system, whereas when it is decided that the image data is not inputted from said external system, said image input/output interface means selects said image pick-up means as the input source to thereby output the image data supplied from said image pick-up means to said image data selecting means and said external system. - View Dependent Claims (12, 13, 14, 15)
