Abstract
The invention provides a method and system for image processing, comprising the step of estimating a value for one or more clipped channels of one or more clipped pixels in a multi-channel image in dependence on information obtained from the unclipped channels of the one or more clipped pixels and from one or more unclipped pixels near to the one or more clipped pixels. The invention provides a method that enables values for any or all of the channels that have experienced clipping to be estimated.
Claims91
A method of image processing, comprising the step of:
- estimating a value for one or more clipped channels of one or more clipped pixels in a multi-channel image in dependence on information obtained from the unclipped channels of said one or more clipped pixels and from one or more unclipped pixels near to said one or more clipped pixels.
A digital image processor comprising processing means adapted to estimate a value for a clipped channel of one or more singly clipped pixels in a digital image in dependence on information obtained from the unclipped channels of said one or more singly clipped pixels and from one or more unclipped pixels near to said one or more singly clipped pixels.
A digital camera, comprising:
- capture means to capture a pixelated digital image of an object;
- and
- processing means adapted to estimate a value for a clipped channel of one or more singly clipped pixels in the pixelated digital image in dependence on information obtained from the unclipped channels of said one or more singly clipped pixels and from one or more unclipped pixels near to said one or more singly clipped pixels.
A digital photofinishing system, comprising:
- input means to receive a pixelated digital image to be processed;
- and
- processing means adapted to estimate a value for the clipped channel of one or more singly clipped pixels in the pixelated digital image in dependence on information obtained from the unclipped channels of said one or more singly clipped pixels and from one or more unclipped pixels near to said one or more singly clipped pixels.
A method of image processing, comprising the steps of:
- identifying pixels in a multi-channel image where at least one channel value is clipped;
- generating a declipping relationship based on channel values from pixels that are not clipped;
- and
- applying-said declipping relationship to declip clipped channel values at said identified pixels.
