摘要： An illuminating member (4) that, independent of any image content, comprises a central region (5) and an enclosing region (6), wherein said enclosing region (6) is adapted to emit light of lower quality than the light emitted by the central region (5). The illuminating member is adapted to illuminate a display panel (2) of a display device. Byhaving the enclosing region emit light of lower brightness (dimming) a significant power reduction can be achieved for a wide range of typical images while largely maintaining the perceived image quality. Further, byusing light emitting elements of lower quality for the enclosing region, manufacturing costs may be reduced while largely maintaining the perceived image quality.

摘要： A color mapping method maps an input image signal (IS) into an output image signal (OS) for a display (DD) with display pixels (Pi) having sub-pixels (RP, GP, BP, YP) with primary colors (RW, GW, BW, YW) defining a display color gamut (WG). A look-up table (1) comprises stored luminances (LU) of reflective spectra (RS) at different chromaticities (λO) within the display color gamut (WG). The reflective spectra (RS) are spectra of reflective objects (RO) having a substantial maximum reflectivity at the corresponding chromaticities (λO). The color mapping method comprises a gamut mapping (2), retrieving (3) a looked-up luminance (Yl), a factor determination (4), and adapting the mapped luminance (Ym; Y). The gamut mapping (2) maps the input image signal (IS) having input pixel colors defined by an input luminance (Y) and an input chromaticity (x, y) into a mapped image signal (MS) having corresponding mapped pixel colors defined by a mapped luminance (Ym; Y) and a mapped chromaticity (xm, ym). The input pixel colors lie within an input color gamut different than the display color gamut (WG). The looked-up luminance (Yl) is retrieved (3) by looking up the stored luminance (LU) in the look-up table (1) at the mapped chromaticity (xm, ym). The factor (F) is determined (4) from a difference between the looked-up luminance (Yl) and the mapped luminance (Ym; Y). The mapped luminance (Ym; Y) is adapted (5) by using the factor (F; G) to obtain an output luminance (Ys) nearer to the looked-up luminance (Yl) than the mapped luminance (Ym). The image output signal (OS) is defined by the mapped chromaticity (xm, ym) and the output luminance (Ys).

摘要： A light output device (1) comprising: a first segment (2d) controllable to have a first luminance; a second segment (2e) adjacent to the first segmentandcontrollable to have a second luminance higher than the first luminance; and a border region (3)locatedat an interface between the first (2d) and second (2e) segmentsandcomprising a first segment portion (31) and a second segment portion (32), wherein the first (2d) and second (2e) 5 segments are configured such that the border region (3) has a luminance higher than the first luminance and lower than the second luminance when the first segment (2d) has the first luminance and the second segment (2e) has the second luminance. The border region makes the luminance transition between adjacent segments of different luminance levels less abrupt. The contrast between such adjacent segments as 10 perceived by a user is reducedthereby. Thus, it may be prevented that a clear line is visible at the interface between the segments even though the difference in luminance is substantial.

摘要： A method of gamut mapping maps an input image composed of pixels and having an input gamut (IG) defined by input RGB primaries (Ri, Gi, Bi) to a reproduction gamut (RG) defined by reproduction RGB primaries (Ro, Go, Bo). The reproduction gamut (RG) is narrower than the input gamut (IG). An input signal (RGBin) defined with respect to the input RGB primaries (Ri, Gi, Bi) is color transformed (1) into a transformed signal (RGBt) defined with respect to the reproduction RGB primaries (Ro, Go, Bo), whereby color information of the pixels (Pl, P2, P3) within the reproduction gamut (RG) is preserved. Scaling factors (SFi) indicating a distance between on the one hand pixels (Pl, P2, P3) of the transformed signal (RGBt) which are outside the reproduction gamut (RG), and on the other hand an edge of the reproduction gamut (RG) are determined (2). The scaling factors (SFi) of pixels (Pl, P2, P3) of the transformed signal (RGBt) are spatial low-pass filtered (3) to obtain filtered factors (FFi) for these pixels (Pl, P2, P3). Component signal values of the transformed signal (RGBt) of the pixels (Pl, P2, P3) are corrected (4) in response to the filtered factors (FFi) to obtain reproduction signal values (RGBo) which are input values (RGBi) moved towards inside the reproduction gamut (RG).

摘要： A light-guide (2; 41; 81; 91) configured to guide light within the light-guide through reflections between opposite faces (14, 15) thereof. The light-guide comprises a first light-guide portion (9e) controllable to selectively outcouple light traveling in a first direction of propagation within the light-guide (2; 81; 91) through at least one of the faces (14, 15); and a second light-guide portion (9d, 9f) controllable to selectively outcouple light traveling in a second direction of propagation, different from the first direction of propagation, within the light-guide (2; 41; 81; 91) through at least one of the faces (14, 15). Hereby, output of light that has been injected into the light-guide can be controlled not only through the outcoupling state of a selected portion of the light-guide, but also through the direction of propagation within the light-guide of the injected light.
