Abstract A horizontal contour signal generation circuit in a single chip color camera comprises a first horizontal contour signal generation circuit provided in a stage succeeding a first horizontal low-pass filter, a second horizontal contour signal generation circuit provided in a stage succeeding a second horizontal low-pass filter, and a selection circuit for adaptively selecting and outputting the first horizontal contour signal generated by the first horizontal contour signal generation circuit and the second horizontal contour signal generated by the second horizontal contour signal generation circuit on the basis of chroma information for each predetermined area calculated on the basis of a color difference signal, the first horizontal low-pass filter having the property of passing a higher frequency component, as compared with the second low-pass filter.
