39、es. The standard environmental conditions for the measurements of autostereoscopic display devices are (25 5) C temperature, 45 % to 75 % relative humidity, and 86 kPa to 106 kPa pressure. 4.1.2 Illumination conditions Standard dark room conditions shall be applied. In standard dark room conditions,

40、 the illuminance at any position on the screen (the display device screen) is below 0,3 lx in all directions. NOTE Illuminance is measured without the measured display or in conditions where the display is turned off. 4.2 Light measuring device 4.2.1 General The LMD used for measurements of the disp

41、lays shall be checked for the following criteria and specified accordingly: aperture size (window function of LMD) (see 4.2.2); sensitivity of the measured quantity; errors caused by veiling glare and lens flare (i.e. stray light in optical system); timing of data-acquisition, low-pass filtering and

42、 aliasing-effects; linearity of detection and data-conversion; resolution and moir in the use of two-dimensional LMD. A point-measurement LMD, such as a spot luminance meter, or a two-dimensional LMD such as a CCD area detector shall be used for these measurements. A conoscopic type LMD can be used

43、for some measurements. When using a two-dimensional LMD and/or a conoscopic type LMD, they shall be calibrated, so that the measurement results correspond to those of the point-measurement LMD. The specification of the LMD used shall be noted in the report as in the example shown in Table 1. NOTE 1

44、The point-measurement LMD measures the luminance and/or colour coordinate at each measurement point on the screen. A two-dimensional LMD measures the map of luminance and/or colour coordinate over the measurement area of the screen. A conoscopic type LMD measures the directional characteristics of l

45、uminance and/or colour coordinate at each measurement point on the screen. NOTE 2 A point-measurement LMD usually has higher sensitivity than a two-dimensional LMD. A two-dimensional LMD measures the uniformity of the measuring area more easily than a point-measurement LMD. BS EN 62629-22-1:20136262

47、orimetric filters CIE 1931 colour matching functions for a 20observer 4.2.2 Aperture size The aperture size (entrance pupil, see CIE 69) of an LMD including point measurement and two-dimensional type LMDs (smaller than the size of the object lens of the LMD) shall be equal to or smaller than 8 mm. W

48、hen a larger aperture LMD is used, the measurement results shall be checked so that the results are equivalent to those of the smaller aperture LMD. The aperture size shall be reported by the supplier (the manufacturer of the 3D display device) in the relevant specification. NOTE In the measurement

49、of autostereoscopic displays, the aperture size of the LMD greatly affects the measurement results. So the LMD aperture size is defined in this document. The aperture size similar to the size of the pupil of an eye is ideal for the measurements (e.g. crosstalk), but smaller aperture decreases sensitivity. The size of 8 mm is small enough for the measurement and large enough for the sensitivity. The exact value of the
