Vehicle surroundings display unit and a method of displaying vehicle surroundings
First Claim
1. A vehicle surroundings display unit, comprising:
- a pick-up unit configured to pick up a video of vehicle surroundings;
an approaching vehicle sensor configured to sense, based on the video picked up by the pick-up unit, an approaching vehicle which is approaching a subject vehicle;
a display processor configured to perform an operation to display the approaching vehicle sensed by the approaching vehicle sensor while distinguishing the approaching vehicle from an obstacle which is not approaching the subject vehicle;
a display unit configured to display the video which has undergone the displaying operation by the display processor; and
a frequency decomposing unit configured to make the following operations detecting one or more frequencies;
decomposing a time-varying component of one or more pixels of the picked-up video for each of the one or more frequencies,extracting one or more pixels having a frequency of the time-varying component higher than a certain frequency, andof the thus extracted one or more pixels of the picked up video, displaying the extracted one or more pixels in a vehicle area.

Abstract
A vehicle surroundings display unit, including: 1) a pick-up unit for picking up a video of vehicle surroundings; 2) an approaching vehicle sensor for sensing, based on the video picked up by the pick-up unit, an approaching vehicle which is approaching a subject vehicle; 3) a display processor for displaying the approaching vehicle sensed by the approaching vehicle sensor while distinguishing the approaching vehicle from an obstacle which is not approaching the subject vehicle; 4) a display unit for displaying the video which has undergone the displaying operation by the display processor; and 5) a frequency decomposing unit to make the following operations: decomposing a time-varying component of a pixel of the picked-up video for each frequency, extracting the pixel having a frequency of the time-varying component higher than a certain frequency, and of the thus extracted pixels of the picked up video, displaying the pixels in a vehicle area.

11. A method of displaying vehicle surroundings, comprising:
-
picking up a video of the vehicle surroundings; sensing, based on the video thus picked up, an approaching vehicle which is approaching a subject vehicle; performing a displaying operation to display the approaching vehicle thus sensed while distinguishing the approaching vehicle from an obstacle which is not approaching the subject vehicle; displaying the video which has undergone the displaying operation of the approaching vehicle; and decomposing a frequency, the decomposing including the following sub-operations detecting one or more frequencies; decomposing a time-varying component of one or more pixels of the picked-up video for each of the one or more frequencies, extracting one or more pixels having a frequency of the time-varying component higher than a certain frequency, and of the thus extracted one or more pixels of the picked up video, displaying the extracted one or more pixels in a vehicle area.

12. A vehicle surroundings display unit, comprising:
-
picking-up means for picking up a video of vehicle surroundings; approaching vehicle sensing means for sensing, based on the video picked up by the picking-up means, an approaching vehicle which is approaching a subject vehicle; display processing means for performing an operation for displaying the approaching vehicle sensed by the approaching vehicle sensing means while distinguishing the approaching vehicle from an obstacle which is not approaching the subject vehicle; displaying means for display processing the video which has undergone the displaying operation by the displaying means; and frequency decomposing means configured to make the following operations detecting one or more frequencies; decomposing a time-varying component of one or more pixels of the picked-up video for each of the one or more frequencies, extracting one or more pixels having a frequency of the time-varying component higher than a certain frequency, and of the thus extracted one or more pixels of the picked up video, displaying the extracted one or more pixels in a vehicle area.
