Japan ITE association (The institute of Image Information and Television Engineers) to make 2 k / 4 k, 8 k high resolution, wide color gamut standard Image, research and development provides The user The required standard Image.
Japan association of ITE standard image conforms to the ITU - R BT. 2020 static high resolution image formats, wide color gamut, provide 12/10 bits wide color gamut color depth test pattern.
Shot across a large room full range wall to deposit a lot of books on the shelf, in the photo paper shadow covers the title of the book, to provide users with "title readability" can directly evaluate the resolution of the display device.Photo in addition to general lighting, also used in the spotlight, intensity of the bookshelf of each area is different, especially in the dark, can be used to evaluate the dark parts of the display device display features.Can also help assess due to transformation and image processing of the resolution of fuzzy character, quantitative aliasing, distortion and so on influence of degradation.
In light of wooden floor in the room with all kinds of antique music box.Under the condition of high resolution photograph, the adornment of the sculpture, the simple sense of art, music equipment wood grain and subtle imprinting are captured in the image, can be used to compare the equipment resolution and reproducibility between video format.In addition, the shadow of the wood can be used for the human eye to evaluate black reproducibility, music box engraved with letters can also be used to assess the readability.
The whole picture composition has detailed texture depth, applicable to evaluate the rendered image size and resolution screen sense of reality and immersed sense.Moss sharpness and color, quality and texture of the tree on the surface of the rock, the edges of the plant leaf, etc., may be caused by image processing fuzzy, mixing and quantization distortion.Leaf surface visible veins, rock shadows of moss, can also be applied to evaluate related degradation caused by image coding.
The kimono is in the photo with complex pattern of Kara - ori (China knitting).Fine texture, fabric pattern is colourful, applicable to evaluate the resolution of the display devices, tone and image coding, etc., including the detection of the pine tree figure in the graph and wood are also suitable for assessment of degradation in the process of image processing, than image quality change caused by different video formats.
Picture of bright and dark areas in detailed textures, applicable to assess the details of the degradation caused by image processing and image coding, and gray scale and color deterioration, color glass of red, yellow, blue, green wide color gamut and black pillar, including fine characters, can assess the character of degradation due to transformation and image processing and readability.
Specimen photo contains a very fine texture image, scales texture, depending on the viewing conditions and the display specification can be effectively applied to analyte test to check the resolution and color, suitable for evaluating change caused by image format conversion of resolution, photo shadow butterfly and dust in the background image displayed in a low frequency signal, can see the black level differences.
Blue background of the sailing model, the flowers and the doll's testing figure, recording images by using a shallow depth of field, before and after sailing have fuzzy effect, as well as in the picture, full of water glass and doll's lace is especially suitable for evaluation of chroma key processing.
Photos for coral reef emerald sea, across the ocean color HDTV is suitable for wide color gamut color gamut reproduction and color evaluation.Detection figure at the bottom right shade contrast sunshine place, can be used to evaluate the dark parts of the display device display features.In addition, the junction of the sky and the sea brightness changes greatly, applicable to evaluate the monitor Local Dimming (Local Dimming) features.
For wide color gamut standard test images, colorful flowers without clearance is arranged, suitable for wide color gamut reproduction and tonal assessment, testing figure shade between the lower right corner and flower, can be used to evaluate the dark parts of the display device display features.Petals detailed textures, applicable to assess a display image size and resolution presented lifelike image quality.
Applicable to evaluation of 4 k and 8 k screen size and image format differences between the telepresence.There were many masts and ropes, can be used to evaluate the fuzzy, aliasing caused by image coding downward and quantization distortion of image quality.Detection figure in the sky gradually layer, very suitable for evaluating the monitor layer change gradually.The detection of the graph is a single photo, please note that because of the use of pseudo color noise filter and lead to pseudo color and bleeding.
Each test pattern are designed according to different testing project, collect images suitable for evaluating the following items:
| The picture | The resolution of the | level | tonal | To deal with degradation | readability | telepresence | Wide color gamut |
