Abstract
Apparatus comprises an image data encoder to encode a current image region of an image, the image data encoder being operable in at least two modes of operation; a controller to control a mode of operation of the image data encoder in dependence upon the encoded data for the current image region meeting a predetermined criterion; and prediction circuitry configured to predict, from one or more properties of one or more image regions other than the current image region, whether the encoded data for the current image region will meet the predetermined criterion.
Claims36
An apparatus comprising:
- an image data encoder configured to encode a current image region of an image, the image data encoder being operable in at least two modes of operation;
- a controller configured to control a mode of operation of the image data encoder in dependence upon the encoded data for the current image region meeting a predetermined criterion;
- and
- prediction circuitry configured to predict, from one or more properties of one or more image regions other than the current image region, whether the encoded data for the current image region will meet the predetermined criterion.
An apparatus comprising:
- an image data decoder configured to decode a current image region of an image, the image data decoder being operable in at least two modes of operation;
- a controller configured to control a mode of operation of the image data decoder in dependence upon the encoded data for the current image region meeting a predetermined criterion;
- and
- prediction circuitry configured to predict, from one or more properties of one or more image regions other than the current image region, whether the encoded data for the current image region will meet the predetermined criterion.

A method comprising:
- encoding a current image region of an image, according to one of at least two modes of operation;
- controlling a mode of operation of the image data encoding in dependence upon the encoded data for the current image region meeting a predetermined criterion;
- and
- predicting, from one or more properties of one or more image regions other than the current image region by circuitry, whether the encoded data for the current image region will meet the predetermined criterion.
