Abstract
A color signal processing device can correct color phase distortion for each luminance value by using a small-capacity memory and in a circuit configuration having a small chip area and low power consumption. The present invention relates to a color signal processing device including a matrix coefficient storage section that stores a plurality of first matrix coefficients corresponding to a plurality of evaluation values set in advance and a predetermined offset value, an evaluation value calculation section that calculates a predetermined evaluation value based on each of a plurality of color component signals contained in a first color signal, a matrix coefficient interpolation operation section that generates a second matrix coefficient based on the predetermined evaluation value calculated by the evaluation value calculation section and the plurality of first matrix coefficients, a matrix operation section that performs an operation based on each of the color component signals in the first color signal and the second matrix coefficient to generate a second color signal containing a plurality of color component signals, and an offset operation section that performs an operation based on the predetermined offset values and the second color signal.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
