Imaging system display processor

An imaging system display processor that is responsive to first and second image signals depicting a common entity, said first image signal having a greater detail resolution than said second image signal, and said second image signal having greater contrast resolution than said first image signal, said display processor comprising:

• a first input for receiving the first image signal;
• a second input for receiving the second image signal;
• a look-up table having at least two dimensions and coupled to the first and second inputs and responsive to at least the first and second image signals to generate an output signal, said output signal combining both detail resolution of the first image signal and contrast resolution of the second image signal.

An imaging system display processor that is responsive to first and second image signals depicting a common entity, said first image signal having a greater detail resolution than said second image signal, and said second image signal having greater contrast resolution than said first image signal, said display processor comprising:

• a first input for receiving the first image signal;
• a second input for receiving the second image signal;
• means, coupled to the first and second inputs, for forming an output signal as a weighted combination of at least the first and second image signals, said weighted combination comprising a weighing factor that varies in accordance with both of the first and second image signals.

An imaging system display processor that is responsive to first and second image signals depicting a common entity, said first image signal having a wider bandwidth than said second image signal, said display processor comprising:

• a first input for receiving the first image signal;
• a second input for receiving the second image signal;
• means, coupled to the first and second inputs, for forming an output signal as a function of at least the first and second image signals, said output signal characterized by a wider bandwidth portion that varies in accordance with the first image signal and a narrower bandwidth portion that varies in accordance with the second image signal.

A display processor for an imaging system that generates a first image signal depicting an entity comprising first regions of a tissue and second regions of blood, said display generator comprising:

• means for generating a second image signal depicting the entity, said second image signal comprising reduced detail resolution and improved contrast resolution as compared to the first signal, said second image signal encoding multiple levels of contrast as appropriate to the tissue throughout the first region;
• and
• means for superimposing at least the first and second image signals to generate a composite image signal which combines detail information of the first image signal and contrast information of the second image signal.

A display processor for an imaging system that generates a first image signal depicting an entity comprising first regions of a tissue and second regions of blood, said display generator comprising:

• a motion estimator responsive to the first image signal and operative to generate a second image signal, said second image signal comprising reduced detail resolution and improved contrast resolution as compared to the first signal;
• and
• means for superimposing at least the first and second image signals to generate a composite image signal which combines detail information of the first image signal and contrast information of the second image signal.
