PURPOSE:To attain accurate color picture detection by detecting an area in which prescribed number of picture elements discriminated to be color picture elements are adjacent. CONSTITUTION:Density data, MCF and SCF signals outputted from a CS(color separate means) 3 are given to a ghost correction means 4, in which ghost is discriminated by taking notice of consecutive picture elements of the MCF and SCF in the main and subscanning directions and when the pattern is coincident with a predetermined pattern. A picture element discriminated to be a color ghost is set to the MCF and a picture element discriminated to be a black ghost is set to the SCF as a flag. A CPU 5 uses a microprocessor and a ROM/RAM, a communication circuit, a timer circuit and an I/O circuit to control an original radiation lamp of an image input terminal section, a motor of an optical system and a digital processing means 2, the CS 3 and the means 4. Furthermore, an automatic color detection means ACS 6 is controlled and based on information presence of a color picture from the means 6, a picture recording section and a copy number counter are controlled. Thus, a color picture of an original is accurately detected. |
