摘要： The present invention relates to a lamp lighting technique for lighting multiple lamps safely without luminance irregularities. The present lamp lighting circuit includes multiple closed loops wherein a predetermined number of lamps and the secondary windings of the predetermined number of transformers are connected serially. At least one of the primary windings of the transformers employed for each closed loop is connected to the primary winding of the transformer employed for another closed loop serially. Thus, current of the lamps included in the closed loop is made uniform, and also current is made uniform even between the closed loops by connecting the primary windings of the transformers serially. According to the present invention, with regard to serial connection of the primary windings of the transformers, even if the number of transformers is limited, current uniformity can be propagated to the entirety by subjecting closed loops to catenation consecutively.

摘要： An overflow suppression technique that is effective for avoiding degradation in image quality is provided. A fundamental waveform and detail is extracted out of an input RGB signal. A suppression gain generation unit 614 generates a suppression gain from the extracted fundamental waveform. Multipliers 612a and 612b multiply the detail and the fundamental waveform by the generated suppression gain, respectively. Then, an adder 626 combines them together for a mixed output. Alternatively, equalization processing is performed as follows. A low frequency component fundamental waveform is obtained as a result of the passing of an input RGB signal through a low pass filter 622. A suppression gain is generated from the low frequency component fundamental waveform. Then, the input itself is multiplied by the suppression gain to obtain an output.
