An image signal processing apparatus of an optical scanning scheme is provided to scan various images by enabling a linear light source fixed on a belt to make a linear movement and scanning an image only when the linear light source makes the linear movement. An input unit receives an image signal. A decompressing unit decompresses inputted compressed information into the original information. If the inputted information does not correspond to resolution of a device, a resolution converting unit processes or downsizes the inputted information according to the resolution. A chromaticity converting unit changes the characteristics of chromaticity coordinates or the like according to light emission characteristics and color characteristics of a light emitting device. A scan information converting unit changes a generally used image signal and screen display information into a position of screen display information and time display information according to a scanning method. A distributing unit distributes converted information to be transmitted to the light emitting device.
