IMAGE PROCESSING METHOD OF VEHICLE CAMERA AND IMAGE PROCESSING APPARATUS USING THE SAME
First Claim
1. An image processing apparatus of a vehicle camera, comprising:
- a light source extraction unit configured to extract light sources from a first frame exposed to light sources during a first time and to extract light sources generating motion blurs from a second frame exposed to the light sources during a second time longer than the first time;
a target light source classification unit configured to classify a first target light source that belongs to the light sources of the first frame and that does not move and a second target light source that belongs to the light sources of the second frame and that does not move; and
a motion determination unit configured to estimate a first location that is a central point of the first target light source and a second location that is a central line comprising a central point of the second target light source, compare the first location with the second location, and determine whether or not a pitch motion of the vehicle has occurred.

Abstract
Disclosed herein is an image processing apparatus of a vehicle camera, including a light source extraction unit configured to extract light sources from a first frame exposed to light sources during a first time and to extract light sources including motion blurs from a second frame exposed to the light sources during a second time longer than the first time, a target light source classification unit configured to classify a first target light source that belongs to the light sources of the first frame and that does not move and a second target light source that belongs to the light sources of the second frame and that does not move, and a motion determination unit configured to estimate a first location that is the central point of the first target light source and a second location that is the central line including the central point of the second target light source, compare the first location with the second location, and determine whether or not a pitch motion of the vehicle has occurred.

6. An image processing method of a vehicle camera, comprising:
-
extracting light sources from a first frame that has been obtained by the vehicle camera and that has been exposed to light sources during a first time; classifying a first target light source that belongs to the extracted light sources and that does not move; computing a first location that is a central point of the first target light source; extracting light sources generating motion blurs from a second frame that has been obtained by the vehicle camera and that has been exposed to light sources during a second time longer than the first time; classifying a second target light source that belongs to the light sources extracted from the second frame and that does not move; computing a second location that is a central line comprising a central line of the second target light source; comparing the first location with the second location; and determining whether or not a pitch motion of the vehicle has occurred based on a result of the comparison between the first location and the second location. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)
