Abstract
A continuous-motion line-array telecine has a solid-state sensor comprising linear array sensor elements (101, 201, 301). For multi-standard operation compensation is provided for vertical misregistration due to different linear array sensor positions as seen at the sensor plane. The compensation is provided by relative delays (160, 260, 360) corresponding to vertical scan shifts of integral numbers of lines, and vertical interpolation circuits (110, 210, 310) for interpolating between lines for compensating any misregistration equivalent to any residual non-integral vertical scan spacing.
