摘要： The display apparatus includes an image display element being driven based on a digital video signal, a quantizing part converting an input analog image signal into the digital video signal based on a quantization phase and a quantization frequency, and a converting part converting an input value into an output value, the input value being a difference value of signal values of pixels adjacent to each other in the digital video signal. The apparatus includes an accumulating part accumulating the output values from the converting part that converts the difference values obtained over entire pixels in one frame of the digital video signal to produce an accumulation evaluation value, and a controller adjusting the quantization phase in the quantizing part such that the accumulation evaluation value becomes maximum. The output values a(m) for the input values k1, k2 and k3 satisfy conditions of a(k1+1)−a(k1)

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.
