摘要： A characteristic image detection interpolation unit performs interpolation processing for increasing the luminance value in low-luminance area which is partly present in an input image. A minimum value filter unit executes minimum value filter processing on an image subjected to the interpolation processing, and a lowpass filter performs lowpass filter processing on the image subjected to the minimum value filter processing, thereby generating a low-frequency component image. A subtracter generates a high-frequency component image by subtracting the low-frequency component image from the input image. Coefficient multiplier adds the luminance value of the high-frequency component image to the input image by a preset ratio K1, thereby generating a high-frequency component enhanced image. A selector alternately outputs the low-frequency component image and the high-frequency component enhanced image.

摘要： The third image signal is generated by multiplying the second image signal constituted by low-frequency components by K. If the fourth image signal obtained by adding the third image signal to the first image signal constituted by high-frequency components falls within a predetermined range, the third image signal is output, whereas if the fourth image signal includes a portion exceeding the range, an image signal obtained by correcting the third image signal is output. A composition signal of the output image signal and the first image signal is generated. The fifth image signal is generated by multiplying the third image signal by a correction amount γ of the third image signal. As a sub-frame of interest, either the composition signal or the fifth image signal is output.

摘要： Image signals input via input terminals are selected by a selector. The selected image signals are combined and displayed on the same screen of a display device. The display screen includes one main screen and a plurality of sub screens. In the case where a moving image is displayed on the main screen, images displayed on the sub screens are updated when the moving image displayed on the main screen are in a still state. The modes of the image signals are detected only when they are input for the first time, the process performed upon the image signals input after that is controlled in accordance with information stored in a memory.
