  2. 4x4 house - Wikipedia

    en.wikipedia.org/wiki/4x4_house

    The 4x4x house is a four story tower with 4m x 4m dimensions (13x13 feet) in a 16.5 foot-square space. [1] [4] The overall shape and location of the building is evocative of a watchtower. [5] The house is encased in concrete and deep in the ground to resist to lateral forces.

  3. Ordered dithering - Wikipedia

    en.wikipedia.org/wiki/Ordered_dithering

    Equivalently, the size of the map selected should be equal to or larger than the ratio of source colors to target colors. For example, when quantizing a 24 bpp image to 15 bpp (256 colors per channel to 32 colors per channel), the smallest map one would choose would be 4×2, for the ratio of 8 (256:32).

  4. Pixel density - Wikipedia

    en.wikipedia.org/wiki/Pixel_density

    Since most digital hardware devices use dots or pixels, the size of the media (in inches) and the number of pixels (or dots) are directly related by the 'pixels per inch'. The following formula gives the number of pixels, horizontally or vertically, given the physical size of a format and the pixels per inch of the output:

  5. Block Truncation Coding - Wikipedia

    en.wikipedia.org/wiki/Block_Truncation_Coding

    Using sub-blocks of 4×4 pixels gives a compression ratio of 4:1 assuming 8-bit integer values are used during transmission or storage. Larger blocks allow greater compression ("a" and "b" values spread over more pixels) however quality also reduces with the increase in block size due to the nature of the algorithm.

  6. Display size - Wikipedia

    en.wikipedia.org/wiki/Display_size

    Common screen dimensions are listed in the table below (the most common diagonal dimensions in inches as of 2020 are bolded). If the display is not listed, then the following equations can be used. Note that D is the diagonal (in centimeters or inches), W is the width (in pixels), and H is the height (in pixels).

  7. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...

  9. Optical format - Wikipedia

    en.wikipedia.org/wiki/Optical_format

    Optical format is a hypothetical measurement approximately 50% larger than the true diagonal size of a solid-state photo sensor.The use of the optical format means that a lens used with a particular size sensor will have approximately the same angle of view as if it were to be used with an equivalent-sized video camera tube (an "old-fashioned" TV camera).
