摘要： PROBLEM TO BE SOLVED: To obtain a magnified image having a sense of a resolution without causing an unnatural change of luminance in the vicinity of an edge. SOLUTION: An input image (Din) is magnified to output a first magnified image (D2A)(2A), and a high-frequency component image (D1) of the input image (Din) is magnified to output a second magnified image (D2B)(2B). A high-frequency component of the second magnified image (D2B) is extracted to output a first intermediate image (D32A)(32A), and a second intermediate image (D32B) obtained by performing nonlinear processing on the second magnified image (D2B) is outputted (30). The device includes at least one of a first frequency component image correction means (33A) which outputs a third intermediate image (D33A) based on the second magnified image (D2B) and the first intermediate image (D32A), and a second high-frequency component image correction means (33B) which outputs a fourth intermediate image (D33B) based on the second magnified image (D2B) and the second intermediate image (D32B).

摘要： PROBLEM TO BE SOLVED: To provide an enhanced image without causing an overshoot even when an input image includes a folding component on a high frequency component side or does not include sufficient high frequency component. SOLUTION: In a first intermediate image generation means 1, an intermediate image D1 from which a component in a specific frequency band of the input image DIN is extracted is generated. In a second intermediate image generation means 2, an intermediate image D2 having a higher frequency component than the intermediate image D1 is generated. In an intermediate image processing means 3M, an intermediate image D3M in which pixel values of the intermediate image D1 are amplified is generated. In an intermediate image processing means 3H, an intermediate image D3H in which pixel values of the intermediate image D2 are amplified is generated. In an addition means 4, the input image DIN, the intermediate image D3M, and the intermediate image D3H are added to obtain an output image DOUT. A first amplifying factor D3MA and a second amplifying factor D3HA are determined according to pixel values of the input image DIN. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent resolution feeling emphasis processing from being doubled, and excessive resolution feeling emphasis processing from being performed when both of a video recording and playback device and an image display device have resolution feeling emphasis processing function in an emphasis processing circuit. SOLUTION: When the video recording and playback device 1 is connected to the image display device 3, a control circuit 16 is connected to a control circuit 34, whether a signal processing means 32 of the image display device 3 has the resolution feeling emphasis processing function is detected, and when the signal processing means 32 has the resolution feeling emphasis processing function, a control is made so that the resolution feeling emphasis processing is not performed in a signal processing means 15. In the image display device 3, the signal processing means 32 is controlled so that the resolution feeling emphasis processing does not become excessive based on control information of the control circuit 16 by the control circuit 34.

摘要： PROBLEM TO BE SOLVED: To sufficiently apply a highlighting process even if an image reproduction signal does not sufficiently include a high frequency component due to compressed image data recorded on a recording medium. SOLUTION: Image data recorded on the recording medium 3 is reproduced by access means 12, and a decompression process is performed by a decompression unit 19 to produce an image reproduction signal. Signal processing means 11 generates a first intermediate image including components around a prescribed frequency band of the image reproduction signal. The first intermediate image is subjected to a nonlinear process to generate a high frequency component. The high frequency component is added to the first intermediate image to generate a second intermediate image. The second intermediate image is added to the image reproduction signal and the added result is output. COPYRIGHT: (C)2011,JPO&INPIT
