    摘要: A PDL interpreter rasterizes image data, which are described in page description language, entered from a host computer, and stores the rasterized image data in an image memory. A CPU discriminates the type of image, pixel by pixel, by referring to the image data stored in the image memory, and stores a discrimination code, which indicates the result of discrimination, in a code memory. The CPU reads out image data that have been stored in the image memory and reads the discrimination code corresponding to these image data out of the code memory. The image data read out of the image memory are subjected to different binarizing processing by two binarizing circuits. Depending upon the discrimination code read out of the code memory, a selector selects the output of one of the two binarizing circuits and sends the selected image data to a printer. Accordingly, it is possible to obtain a high-quality image which is a mixture of images having different characteristics, such as an image containing character or line drawings, continuous grayscale images, etc.

    摘要: The display apparatus includes an AD converter converting an analog video signal into a digital video signal, a phase adjuster and a horizontal start position detector. 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.

    摘要: When an image signal suitable for performing automatic adjustment of an effective image area and a dot clock is not output, the adjustment may be unsuccessfully performed. An effective image area detector detects an effective image area and determines whether an image in the effective image area is a blank image. If a synchronization signal detector determines that there exists a synchronization signal and if the effective image area detector determines that the image is not a blank image, a controller adjusts an area captured as image data by an input signal processor.
