摘要:
It is possible to inhibit side effects, even when an image that has sharp edge regions has been input, using a spatial processing portion (10) outputting surrounding image information US from an input image signal, a control signal generation portion (40) outputting an effect adjustment signal MOD according to a degree of flatness of an edge proximal region, and an effect adjustment portion (20) outputting a synthesized signal MUS that is synthesized by changing a ratio of the image signal IS and the surrounding image information US according to the effect adjustment signal MOD. Further, the side effects are inhibited using a visual processing portion (30) visually processing the image signal IS based on the synthesized signal MUS and the image signal IS.

The invention achieves a visual processing device that can execute precise contrast adjustment on image signals that have been input and that does not cause discrepancies in the output timing of the image signals that are output. The visual processing device is provided with a gain-type visual processing portion that outputs a first gain signal having predetermined gain characteristics with respect to the input image signal, and a correction portion that corrects the input image signal based on the first gain signal.

A visual processing device, display device, visual processing method, program, and integrated circuit that change a strength of visual processing of an image in real-time. A spatial processing portion (2) creates an unsharp signal US from an input signal IS. A target level setting portion (4) sets a predetermined target level value L for setting a range according to which the strength of the visual processing is adjusted. An effect adjustment portion (5) creates a synthesized signal MUS by synthesizing the predetermined target level value L and the unsharp signal US in accordance with an effect adjustment signal MOD that has been set externally. A visual processing portion (3) outputs an output signal OS in accordance with the input signal IS and the synthesized signal MUS, making it possible to change the strength of the visual processing.

The invention provides a visual processing device that has a hardware configuration that does not depend on the visual processing to be achieved. A visual processing device 1 is provided with a spatial processing portion 2 and a visual processing portion 3. The spatial processing portion 2 performs predetermined processing with respect to an input signal IS that has been received as input, and outputs the result as an unsharp signal US. The visual processing portion 3 outputs an output signal OS, which is the input signal IS after visual processing, based on a two-dimensional LUT 4 that lists the relationship between the input signal IS that has been received as input and the unsharp signal US, and the output signal OS.

It is an object of the invention to obtain an image having a better visual effect for the person who will view the visually processed image. A visual processing device 910 comprises an output portion 914 and a transformation portion 915. The output portion 914 outputs a luminance adjustment parameter P2 based on a parameter P1 expressing the ambient light. The transformation portion 915 transforms a luminance of a target pixel based on the luminance adjustment parameter P2 that is output by the output portion 914, a luminance of the target pixel to be subjected to visual processing, and a luminance of surrounding pixels positioned in an area around the target pixel.

摘要:
The grayscale of an input signal is converted without amplifying noise components thereof. A grayscale conversion portion performs grayscale conversion on an input signal IS to create a converted signal TS, a noise reduction degree determining portion determines a noise reduction degree NR that expresses a strength of noise reduction processing to be applied to the converted signal based on the input signal IS and the converted signal TS, and a noise reducing portion executes noise reduction processing on the converted signal TS based on the noise reduction degree NR. By doing this, it is possible to convert the grayscale of the input signal without enhancing the noise.
