An image processing unit comprises a first processing unit (101) which generates a depth indication map for an image. The depth indication map may be, for example, an image object separation mask or a predetermined depth profile or background depth map. A second processing unit (103) generates a modified depth indication map by filtering the depth indication map in response to image characteristics of the image. The image adaptive filtering may, for example, provide a more accurate separation mask and / or may modify the predetermined depth profile to reflect the specific image. A third processing unit (105) generates an image depth map for the image in response to the modified depth indication map. The image depth map comprises data representing a depth of at least one image region of the image. The invention leads to the generation of an improved depth map for an image.

The invention provides a light hollow ceramsite and a production method thereof and belongs to the technical field of artificial lightweight aggregate processing. The light hollow ceramsite is made of a ceramic forming material and a template material, wherein the ceramic forming material is composed of waste paper papermaking dry sludge, fly ash and clay, and the template material is composed of polyphenyl foam particles. The obtained light hollow ceramsite is spherical or similar to a sphere in appearance, a middle cavity is spherical or similar to a sphere, and the middle cavity is separated from the outside through a ceramic structure with wall thickness to be 0.5-2.5mm. According to the light hollow ceramsite, barrel pressure strength is 33MPa, stacking bulk weight is 300-500kg / m<3> and particle size is 5-20mm, and therefore the light hollow ceramsite can be used for preparing high performance light aggregate concrete or suspended bio-film ceramic filter materials used for sewage treatment.

A liquid crystal display including a polarizing plate having a linear polarization axis slanted in relation to a scan line, a transparent pixel electrode, an active element which drives the transparent pixel electrode, and a wire for connecting the active element and the transparent pixel electrode. The wire has an end part so shaped as to be slanted in a direction parallel to or perpendicular to the linear polarization axis.

A method for a focus error signal adjustment in an optical disk device which shapes a focus error signal and enables a high-accuracy focus servo is provided.In a DVD-RAM having an emboss data zone and a rewritable data zone, a focus error signal is generated with the DVD-RAM remaining still in a position where an emboss pit is not formed in the rewritable data zone, and a waveform of the FE signal is shaped so that the waveform is symmetrical with respect to a reference point. Then, the FE signal is generated in the emboss data zone and an amplitude of the FE signal is adjusted. The amplitude of the signal which is obtained by increasing the the amplitude of the FE signal whose amplitude is adjusted by approximately 6 dB is applied to the amplitude of the focus error signal in the rewritable data zone. Consequently, a high-accuracy focus servo based on the FE signal, whose amplitude is adjusted and waveform is shaped, can be achieved without an error caused by the emboss pit.
