Abstract
Abstract An image detection system for a car arranged such that only when the drive angle of a wiper of the car resides within a predetermined image pickup angle range or a predetermined image pickup angle range corrected according to the pan angle of a TV camera unit, a change-over switch is controlled to change over to the side of an image storage from which static image data are provided as outputs. Alternatively, it can be arranged such that a masking range the wiper crosses in all of the scanning lines, of an image in front of the wiper, perpendicula to the moving direction of the wiper is determined from a drive angle of the wiper and only the image of the scanning lines for the wiper is masked and substitued by blank data or static update data.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
141 words
An image detection system for a car having means (3) for driving a wiper (2) and means (6) for detecting an image in front of said wiper (2) from the inside of the car and providing it as data output, characterized by comprising; means (4) for detecting a drive angle of said driving means (3); means (7) for updating-storing the image data output from said image detecting means (6); means (8) for changing the output of said image detecting means (6) over to the output of said updating-storing means (7); and, means (5) for controlling said change-over means (8) to the side of said image updating-storing means (7) only when said drive angle resides in a predetermined image pickup angle range of said image detecting means (6) and for providing, as an output, static image data from said updating-storing means (7).
Claim 2
Dependent Claim
177 words
An image detection system for a car having means (3) for driving a wiper (2) and means (6) for detecting an image in front of said wiper (2) from the inside of the car and providing it as data output, characterized by comprising; means (4) for detecting a drive angle of said driving means (3); means (60) for panning said image detecting means (6) up, down, right and left within a predetermined range and for providing, as an output, the pan angle; means (7) for updating-storing the image data output from said image detecting means (6); means (8) for changing the output of said image detecting means (6) over to the output of said updating-storing means (7); and, means (5) for controlling said change-over means (8) to the side of said image updating-storing means (7) only when said drive angle resides in a predetermined image pickup angle range of said image detecting means (6) which is corrected in response to said drive angle and for providing, as an output, static image data from said updating-storing means (7).
Claim 3
Dependent Claim
82 words
An image detection system for a car as claimed in claim 1 or 2, wherein said updating-storing means (7) includes an image memory (71) continuously updated by the data output of said image detecting means (6) and an output image memory (72) connected to one side of said change-over means (8) and storing and providing as outputs the update image data of said image memory (71) when said change-over means (8) is changed over to the side of said image storage (7).
Claim 4
Dependent Claim
60 words
An image detection system for a car as claimed in claim 1 or 2, wherein said cotrolling means (5) controls said change-over means (8) to the side of said image detecting means (6) when said drive angle resides outside the predetermined image pickup angle range and for providing, as an output, dynamic image data from said image detecting means (6).
Claim 5
Dependent Claim
118 words
An image detection system for a car having means (3) for driving a wiper (2) and means (6) for detecting an image in front of said wiper (2), which is formed of scanning lines perpendicular to the moving direction of said wiper (2), from the inside of the car, characterized by comprising; means (4) for detecting a drive angle of said driving means (3); and, image processing means (50) for calculating, from said drive angle, a masking range said wiper (2) crosses in all of the scanning lines of the image detected by said image detecting means (6) and for masking only the image of the scanning lines in the masking range and providing, as outputs, blank data.
Claim 6
Dependent Claim
121 words
An image detection system for a car having means (3) for driving a wiper (2) and means (6) for detecting an image in front of said wiper (2), which is formed of scanning lines perpendicular to the moving direction of said wiper (2), from the inside of the car, characterized by comprising; means (4) for detecting a drive angle of said driving means; and, image processing means (50) for calculating, from said drive angle, a masking range said wiper (2) crosses in all of the scanning lines of the image detected by said image detecting means (6) and for masking only the image of the scanning lines in the masking range and providing, as outputs, static image data just before masking.
Claim 7
Dependent Claim
83 words
An image detection system for a car as claimed in claim 5 or 6, wherein said image processing means (50) includes a buffer memory (54) continuously updated by the output of said image detecting means (6) for providing as outputs the updated data and a frame memory (56) continuously storing the update image data of said buffer memory (54) and transferring the data therein corresponding to the masking range into said buffer memory (54) only when said wiper (2) crosses the masking range.
