摘要： It is an object of the present invention to provide a video signal processing device, which can produce a digital video signal, excellent in image quality, fully utilizing effective picture elements of the imaging element, without performing a special control of an imaging element driving unit.In accordance with a contour correction gain calculated based on a compression ratio detecting signal outputted from an image compressing unit 21, a contour correction unit 22 can carry out a contour correction on a compressed image. Accordingly, an NTSC/PAL encoder 24 can output a preferable video signal, which has been subjected to an appropriate contour correction. Moreover, a digital outputting unit 25 outputs an uncompressed video signal, and therefore can provide a preferable video signal without deteriorating the effective picture elements of an imaging element.

摘要： Systems and methods for performing edge detection on a surface. An example system includes a camera having a line of sight approximately perpendicular to a plane associated with a camera surface, one or more illumination sources having a line of sight that is less than perpendicular to the plane by a predefined threshold amount, and a processor in signal communication with the camera. The processor receives images generated by the camera, compares the received images, and determines an edge located within one or more of the captured images based on the comparison.
