How to use
This image is used for checking the texture of the entire image. You should focus attention on the bread rolls, the croquettes or the fabric of napkins, observe sharpness of fruits and slices of ham, check brightness of the top surface of the box in wrapping paper, and evaluate reproducibility of details with cauliflower at highest white level. The trunk of the plant and the shades of plates in the image are useful to adjust the darkness of a screen. The piled paper napkins on the left of the image provide an indication of vertical resolution because the part of the image consists of 700～800TV of horizontal wedges and inter-line flicker is likely to become obvious here. The images of pattern of melon and piled plates show whether pairing state happens and things related to interlace scan. The egg is effective to find ghost and reflection caused by matching problem of delay line, also red carnations and the blue can are suitable to check resolution-degradation and waveform distortion, which happen when color-difference signal is band limited, in saturation area. |
