    The tree is at the intersection of two lines, sometimes called a power point[ 1] or a crash point. [ 2] The rule of thirds is a "rule of thumb" for composing visual images such as designs, films, paintings, and photographs. [ 3] The guideline proposes that an image should be imagined as divided into nine equal parts by two equally spaced ...

  3. Moiré pattern - Wikipedia

    en.wikipedia.org/wiki/Moiré_pattern

    Consider two patterns made of parallel and equidistant lines, e.g., vertical lines. The step of the first pattern is p, the step of the second is p + δp, with 0 < δp < p. If the lines of the patterns are superimposed at the left of the figure, the shift between the lines increases when going to the right.

    An image of N pixels height by M pixels wide can have any resolution less than N lines per picture height, or N TV lines. But when the pixel counts are referred to as "resolution", the convention is to describe the pixel resolution with the set of two positive integer numbers, where the first number is the number of pixel columns (width) and ...

    TVL is defined as the maximum number of alternating light and dark vertical lines that can be resolved per picture height. EIA 1956 video resolution target, used to measure TVL. Television lines ( TVL) is a specification of an analog camera or monitor's horizontal image resolution. [ 1] The TVL is one of the most important resolution measures ...

    The verticalhorizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. [1] This involves a bisecting component that causes the bisecting line to appear longer than the line that is bisected. People often overestimate or underestimate the length of the ...

    The reason is to represent a 360° on the horizontal axis and a 180° on the vertical. 3840 × 1600 (2.40:1 or 12:5 ); a number of computer monitors with this resolution have been produced, the first being the 37.5-inch (95 cm) LG 38UC99-W released in 2016.
