Abstract
Disclosed is an intrafield interpolation circuit for interpolating pixel signals between pixel signals sampled based on Multiple Sub-nyquist Sampling Encoding (MUSE). There are provided in this interpolation circuit switches (S4a, S4b, S4c) for selecting pixel signals from delay elements (33h, 33i, 33j). Since these switches are controlled at a suitable timing, correct pixel signals obtained by an operation are interpolated between the sampled pixel signals. In addition, since pixel signals required only for an interpolation processing are handled, multipliers require half the operation speed of a conventional circuit, resulting in an enhanced reliability in operation.
