Abstract: PROBLEM TO BE SOLVED: To appropriately control a light emission luminance by a backlight using a simple process. SOLUTION: A periphery representative value calculation unit 141 calculates, as a periphery representative value, an output luminance obtained by a target block and peripheral blocks around the target block of the backlight formed by a plurality of blocks. A periphery contribution amount calculation unit 142 divides the periphery representative value by a light emission efficiency based on a light emission profile being an output luminance distribution at the time of light emission of the target block, so as to calculate a periphery contribution amount of peripheral blocks to the target block. A light emission level calculation unit 143 divides a necessary light emission amount of the target block by the periphery contribution amount so as to calculate the backlight luminance as a light emission level. The present invention may be applied to an image processing apparatus like a liquid crystal display device. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suppress image deterioration (blurred images) caused by an imaging blur. SOLUTION: An imaging blur correction amount determination unit 21 outputs a signal T1 obtained by performing HPF processing on an image signal T0 as a correction signal for suppressing image blur. An addition unit 22 adds the correction signal T1 to the image signal T0, and outputs an output signal T2 obtained as a result. A frequency switching unit 24 converts a moving speed MV0 into a moving speed MV1 corresponding to a display speed. An LPF unit 23 determines the number of taps of a moving average filter based upon the converted moving speed MV1. Then the LPF unit 23 performs processing by the moving average filter on a corrected image signal T2, and outputs an image signal T3 obtained as a result. Characteristics of the signal T3 match characteristics of a hold blur. The present invention is applicable to a television system. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To suitably correct a luminance signal.
SOLUTION: A correction amount determination unit 11 determines a correction amount for a luminance signal T0 of an image, and outputs a signal T1 including the correction amount as its signal level. A gain calculation unit 14 determines a gain for adjusting the correction amount based upon a color difference signal C0 of the image, and outputs a signal C3 including the gain as its signal level. A multiplication unit 12 multiplies the signal T1 by the signal C3 and outputs a signal T2 obtained as a result. Namely, the level of the signal T2 indicates a correction amount changed by the gain. An addition unit 13 adds the signal T2 to the luminance signal T0, and outputs a signal T3 obtained as a result. The present is applicable to a television system.

Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of displaying a perspective video image.
SOLUTION: An enhance correction unit 11 applies, to an input signal T0, enhance processing corresponding to a moving amount MV and outputs a resultant signal as an output signal T3. An LPF section 22 of an enhance suppression correction unit 12 applies LPF processing to the input signal T0 and outputs a resultant signal as an output signal B1. In that case, a tap amount variable section 21 varies a tap length of the LPF section 22 in accordance with the moving amount MV. When it is judged by a moving amount gap judgement unit 13 that large and small moving amounts MV are mixed, a switch unit 14 outputs the output signal T3 of the enhance correction unit 11 for a portion of the large moving amount MV in a frame image and outputs the output signal B1 of the enhance suppression correction unit 12 for a portion of the small moving amount therein, respectively, as an output signal T4. The present invention may be applicable to television systems.

Abstract: PROBLEM TO BE SOLVED: To provide a significantly clear display of images as converted in frame rate by suppressing the image deterioration (blurred images) which would occur due to an imaging blur. SOLUTION: A higher frame rate converting part 11 subjects an input motion image to a higher frame rate conversion process. For each of a plurality of frames constituting the motion image, an imaging blur suppressing part 13 corrects, based on one or more values, which correspond to the frame to be processed, of the values of parameters indicative of an imaging blur characteristic detected by an imaging blur characteristic detecting part 12, the pixel values constituting the frame to be processed. This can provide a motion image which exhibits a higher frame rate than when inputted and the pixel values of which have been appropriately corrected so as to suppress the imaging blur. The present invention is applicable to a television system. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To more accurately separate an input signal into a component in which an edge steep and large in the change of a signal level is kept and the other component. SOLUTION: A narrow band nonlinear filter 101 extracts an edge component in a comparatively narrow frequency band from an input signal 121 and outputs the edge component as a signal 122, and a wide band nonlinear filter 102 extracts an edge component in a comparatively wide frequency band from the input signal 121 and outputs the edge component as a signal 123. Based upon a differentiated value of the signal 122 supplied from a differentiator 103, a selector 104 outputs a signal 125 whose edge portion is replaced with the signal 123 as an edge component of the input signal 121. Besides, an adder 105 subtracts the output signal 125 from the input signal 121 and outputs a calculated output signal 126 as an edge component of the input signal 121. The invention may be applied to an image processing apparatus. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To apply contour correction to a video signal without causing pre- shoot and overshoot. SOLUTION: A video signal from an input terminal 1 is fed to 1st and 2nd delay means 2, 3 connected in series, and the input output signals from them are fed to 1st-3rd sbtractor circuits 4, 7, 10. The output signal from the 1st-3rd sbtractor circuit 4, 7, 10 are fed respectively to minus sign circuits 6, 9, 12 that convert a signal with positive polarity into a signal with negative polarity through full wave rectifier circuits 5, 8, 11, the signals from the minus sign circuits 9, 12 are fed to a subtractor 14 via a minimum value circuit 13 that extracts either of the signals which is smaller and the subtractor 14 subtracts the output of the circuit 13 from the output of the circuit 6. Then the output signal from the sbtractor 14 is fed through a slice circuit 15 extracting only the negative polarity signal to an adder circuit 16, where the output of the slice circuit 15 is added to an output video signal from the delay means 2 so as to make the gradient of a leading and a trailing of the video signal steep so that the video signal whose image contour is corrected is extracted at an output terminal 17.
