Abstract
Examples of the present disclosure relate to an image processing apparatus comprising a filter to convert a first image data signal into an output image data signal. The filter is configured to resample the first image data signal, having a first sample rate, by a resampling factor, such that the output image data signal has an output sample rate that is different to the first sample rate. The filter is also configured to apply a phase alteration to the first image data signal to compensate a group delay in the first image data signal.

Image processing apparatus comprising a filter to convert a first image data signal into an output image data signal, the filter configured to:
- resample the first image data signal, having a first sample rate, by a resampling factor, such that the output image data signal has an output sample rate that is different to the first sample rate;
- and
- apply a phase alteration to the first image data signal to compensate a group delay in the first image data signal.
An image processing method comprising:
- resampling a first image data signal, having a first sample rate, by a resampling factor to generate an output image data signal having an output sample rate that is different to the first sample rate;
- and
- applying a phase alteration to the first image data signal to compensate a group delay in the first image data signal.
Image processing apparatus comprising a cascaded integrator-comb filter to convert an input image data signal into an output image data signal,
- wherein the cascaded integrator-comb filter is configured to resample the input image data signal, having an input sample rate, by a resampling factor, such that the output image data signal has an output sample rate that is different to the input sample rate.
