    摘要: This invention discloses a color image processing apparatus which judges a saturation of an input color image, and performs image processing in accordance with the saturation judgement result. The apparatus includes an image input means in which a plurality of line sensors for generating color component signals on the basis of different spectral characteristics are parallelly arranged, and means for judging an achromatic area of the color component signals input by the image input means in accordance with a predetermined method. This arrangement performs saturation judgement when a printing operation using only black is performed for a black character or when it is judged whether an original document is a monochrome or color original document.

    摘要: The display apparatus includes an AD converter (6) converting an analog video signal into a digital video signal, a phase adjuster (1) and a horizontal start position detector (7). The detector detects a horizontal start position where an output value of the AD converter becomes a minimum value that exceeds a threshold level in a video horizontal direction. The phase adjuster acquires a start position change phase where the horizontal start position is changed. The phase adjuster calculates a first phase period where the analog video signal starts its transition from a first level to a second (higher) level and then ends the transition. The phase adjuster sets a phase not included in the first phase period as an adjusted phase of the quantization clock.
