Claims
- 1. A charge-coupled device (CCD)-type camera, comprising:
- a first CCD image pick-up device having a column of photosensor elements disposed along a first linear axis;
- a second CCD image pick-up device having a column of photosensor elements disposed along a second linear axis, wherein a first imaginary line passing along and through said first linear axis intersects a second imaginary line passing along and through said second linear axis; and,
- a signal processor for comparing respective image output signals of said first and second CCD image pick-up devices, on a pixel-by-pixel basis, in order to detect smear noise, and for eradicating any detected smear noise, on a pixel-by-pixel basis.
- 2. The camera as set forth in claim 1, wherein the intersection of said first and second imaginary lines forms a 90.degree. angle.
- 3. A method for eradicating smear noise in a charge-coupled device (CCD)-type camera having a first CCD image pick-up device which includes a column of photosensor elements disposed along a first linear axis and a second CCD image pick-up device which includes a column of photosensor elements disposed along a second linear axis, wherein a first imaginary line passing along and through said first linear axis intersects a second imaginary line passing along and through said second linear axis, said method comprising the steps of:
- comparing respective image output signals of said first and second CCD image pick-up devices, on a pixel-by-pixel basis, in order to detect smear noise; and,
- eradicating any detected smear noise, in response to said comparing step, on a pixel-by-pixel basis.
- 4. The method as set forth in claim 3, wherein the intersection of said first and second imaginary lines forms a 90.degree. angle.
- 5. A charge-coupled device (CCD)-type camera, comprising:
- a first CCD image pick-up device including a plurality of vertical CCDs oriented parallel to one another and each including a respective column of photosensor elements, and a horizontal CCD oriented perpendicularly to and coupled to said vertical CCDs;
- a second CCD image pick-up device including a plurality of vertical CCDs oriented parallel to one another and each including a respective column of photosensor elements, and a horizontal CCD oriented perpendicularly to and coupled to said vertical CCDs of said second image pick-up device;
- wherein an imaginary line passing along and through a linear axis of said horizontal CCD of said first CCD image pick-up device intersects a second imaginary line passing along and through a linear axis of said horizontal CCD of said second CCD image pick-up device; and,
- a signal processor for comparing respective image output signals of said first and second CCD image pick-up devices, on a pixel-by-pixel basis, in order to detect smear noise, and for eradicating any detected smear noise, on a pixel-by-pixel basis.
- 6. The camera as set forth in claim 5, wherein the intersection of said first and second imaginary lines forms a 90.degree. angle.
- 7. A method for eradicating smear noise in a charge-coupled device (CCD)-type camera including a first CCD image pick-up device including a plurality of vertical CCDs oriented parallel to one another and each including a respective column of photosensor elements, and a horizontal CCD oriented perpendicularly to and coupled to said vertical CCDs, a second CCD image pick-up device including a plurality of vertical CCDs oriented parallel to one another and each including a respective column of photosensor elements, and a horizontal CCD oriented perpendicularly to and coupled to said vertical CCDs of said second image pick-up device, and, wherein an imaginary line passing along and through a linear axis of said horizontal CCD of said first CCD image pick-up device intersects a second imaginary line passing along and through a linear axis of said horizontal CCD of said second CCD image pick-up device, said method comprising the steps of:
- comparing respective image output signals of said first and second CCD image pick-up devices, on a pixel-by-pixel basis, in order to detect smear noise; and,
- eradicating any detected smear noise, in response to said comparing step, on a pixel-by-pixel basis.
- 8. The method as set forth in claim 7, wherein the intersection of said first and second imaginary lines forms a 90.degree. angle.
