Patent ID: 7643073

Claim:
An image apparatus having an imaging device having a plurality of kinds of color filters that have different spectral sensitivities and are arranged on an imaging surface of said imaging device, comprising: pixel signal slicing unit for slicing an output signal from said imaging device in a two-dimensional area; pixel correlation detection unit for detecting correlation between a center pixel signal and each of a plurality of peripheral pixel signals in the two-dimensional area sliced by the pixel slicing unit; signal correction unit for correcting a signal quantity for each of the pixel signals sliced by said slicing unit on the basis of the output detected by said pixel correlation unit; synchronization unit for extracting each color signal by using a signal corrected by said signal correction unit; said signal correction unit for suppressing pixel signals having low degrees of correlation on the basis of the degree of correlation of each pixel signal in said peripheral pixel signals detected by said pixel correlation detection unit, amplifying pixel signals having higher degrees of correlation and determining a suppression level and an amplification level so that the gain of said synchronization unit becomes constant; said pixel signal slicing unit slicing the output signal of said imaging device in a two-dimensional area; said pixel correlation detection unit detecting correlation of the center pixel signal and its peripheral pixel signals in the area sliced by said slicing unit; said synchronization unit extracting each color signal for a center pixel position of the area sliced by said signal correction unit; and coefficient changing unit for changing a coefficient of said synchronization unit on the basis of a result of said pixel correlation detection unit.
