Field of the Invention The present invention relates to a color signal converting apparatus, which converts a luminance signal and a color difference signal, and an electronic still camera. 2. Description of the Related Art FIG. 13 is a block diagram showing a conventional color signal converting apparatus. In FIG. 13, reference numeral 31 designates an input terminal to which a luminance signal Y and a color difference signal Cb are inputted, and reference numeral 32 designates an output terminal. The luminance signal Y is inputted to a subtracter 34 through a low-pass filter 33. The subtracter 34 subtracts the color difference signal Cb from the luminance signal Y. An output of the subtracter 34 is inputted to a decoder 35. The decoder 35 decodes the output of the subtracter 34 and supplies an error signal E to a converter 36. The error signal E represents an absolute value of the color difference signal Cb, and has a large error (or a color noise) as a value from -(1/2) to +(1/2) of the color difference signal Cb. The converter 36 converts the error signal E into a time-series low-pass signal by use of an averaging filter, and outputs the low-pass signal to the output terminal 32. An output of the converter 36 is fed back to an input of the subtracter 34. In this color signal converting apparatus, by making the averaged value of the error signal E obtained by use of the averaging filter larger than the input value of the error signal E, the low-pass filter 33 removes a color noise generated from a pixel part from the inputted color difference signal Cb, thereby outputting a color difference signal having a high accuracy. The conventional color signal converting apparatus converts only a luminance signal to a high-frequency color difference signal, and does not convert a color difference signal to a high-frequency luminance signal.
