Abstract
An object of the present invention is to provide a color signal generating device where the size of the operational circuit is small and the speed of signal processing is fast. The color signal generating device for converting signals from a first color signal for forming a number of input pixels to a second color signal for forming a number of output pixels is provided with: a signal gradient detecting means for detecting a gradient of color signals in a reference pixel within the number of input pixels; a signal distributing means for comparing the first color signal for the reference pixel where the gradient is detected and the second color signal for the reference pixel of the number of output pixels corresponding to the reference pixel and stored in advance in the case where the gradient is detected, and distributing a color signal to a periphery pixel adjacent to the reference pixel having the second color signal in the case where the first color signal has a color which the second color signal does not; and a signal modifying means for converting the first color signal for forming a number of input pixels to a second color signal on the basis of the distributed color signal.
