	PIXEL (Site not responding. Last check: 2007-09-19)
		Pixels staan hetzij 'uit' (donker) hetzij 'aan' (verlicht, veelal in kleur).
		Het aantal bits per pixel bepaalt het aantal kleuren dat een pixel kan weergeven.
		Hoe hoger de schermresolutie en hoe groter het aantal bits per pixel, hoe meer computergeheugen nodig is om alle informatie op het scherm te verwerken.

	Pixel - Wikipedia, the free encyclopedia
		With care, pixels in an image can be reproduced at any size without the appearance of visible dots or squares; but in many contexts, they are reproduced as dots or squares and can be visibly distinct when not fine enough.
		Pixels on computer monitors are usually square, but pixels used in digital video have non-square aspect ratios, such those used in the PAL and NTSC variants of the CCIR 601 digital video standard, and the corresponding anamorphic widescreen formats.
		When an image file is displayed on a screen, the number of bits per pixel is expressed separately for the raster file and for the display.

	Color depth - Wikipedia, the free encyclopedia
		Color depth is a computer graphics term describing the number of bits used to represent the color of a single pixel in a bitmapped image or video frame buffer.
		Considering red, green, and blue use the same amount of bits for their respective color (with the exception of 16-bit color), the total bits used will be a multiple of 3: like 15-bit color (5 bits each) and 24-bit color (8 bits each).
		While the 8 extra bits are not visible on-screen, they provide protection against accumulating rounding errors when multiple manipulations are performed on a picture, such as modifying image brightness and/or contrast.

	bits from FOLDOC (Site not responding. Last check: 2007-09-19)
		Bit slice processors usually consist of an ALU of 1, 2, 4 or 8 bits and control lines (including carry or overflow signals usually internal to the CPU).
		This is very similar to a bit pattern except that the term "string" suggests an arbitrary length sequence as opposed to a pre-determined length "pattern".
		The advantage of bit stuffing is that only a bit (not a byte) is inserted in the data stream, and that only when the content of the data stream fails to provide a timing signal to the receiver.

	Bit Depth Questionnaire
		The most information that's ever used for displaying a file is 24 bits per pixel because the 16.8 million colors that can be displayed at that level are many more colors than any human eye can discern.
		Extended bit depth is also used for CMYK because each color channel of a true-color image needs to contain a full 256 levels of gray.
		Just to make the discussion of bit depth a bit more confusing, extended bit depth can be used for other purposes, such as extra channels of data that can be used to store masks or texture maps.

	BITS PER PIXEL - Definition
		(bpp) The number of bits of information stored per pixel of an image or displayed by a graphics adapter.
		Allowing 8 bits (1 byte) per component (24 bits per pixel) gives 256 levels for each component and over 16 million different colours - more than the human eye can distinguish.
		Standard VGA uses a palette of 16 colours (4 bpp), each colour in the palette is 24 bit.

	Color Depth - Bits per Pixel (Site not responding. Last check: 2007-09-19)
		The amount of color information in a picture is usually referred to as the color depth or the number of bits per pixel.
		The more bits used for each pixel, the more colors that can be used to draw the pixel.
		Although each pixel must be either "on" or "off", patterns of pixels can be used to give the illusion of various shades of grays.

		Per pixel Gamma correction, a ton of blending modes, depth of field and color fog...
		Bits per pixel is a form of mesurement that shows the number of possible colours that each pixel can use in an image.
		By increasing the number of bits, smoother shades can be shown on screen, therefore eliminating colour banding.

		Being binary each bit can either hold a value of either 1 or 0, it is through linking bits together that you can produce complicated information on each pixel or point of an image.
		So each grid made up of pixels can be referred to by the amount of pixels in a square inch, which is the PPI (pixels per inch).
		It is also dependant upon the amounts of bits per pixel the output device allows, and the color mode the file is saved in.

	8 Bits per Pixel (Site not responding. Last check: 2007-09-19)
		Paletted images can be stored at either 1, 2, 4 or 8 bits per pixel (bpp), provided their pixels have at most 2, 4, 16 or 256 distinct colors, respectively.
		The default heuristics applied when encoding paletted images is to use as few bits per pixel as possible.
		However, it is not uncommon for a bigger number of bits per pixels (usually, 8) to be a better choice, even when a smaller number is also possible to be used.

	Lossless Compression
		Neighbouring pixels are generally highly correlated, as illustrated in Figure 6.
		Prediction of a pixel as the value of the adjacent left pixel resulted in a rate of 5.31 bits per pixel for the error, a compression of 33%.
		Using optimal entropy encoding, it was found that the average coding rate for a 1:2 subsampling pyramid encoder operating on the test images was 6.76 bits per pixel of the original image.

	Part II: Subband Coding for Image Compression
		For M subbands and an average b bits per pixel,Bits allocated to the kth subband is given by
		Bit allocation using the entire image variance is not actually valid in parts a,b and c because only image rows are separated not the columns, actually a mean of row variances would be a better measure
		BPP in all the parts can be reduced by applying Run-Length Coding especially on the High frequency components which have runs of zeros because of quantization.

	FOURCC.org - RGB pixel formats
		Each pixel is represented by a single bit, giving 8 pixels per BYTE in memory.
		The 4 bits used for the pixel give rise to 16 possible values and, hence, a 16 entry colour palette is required to display the image.
		The first of the pixels is drawn using the color specified by the high-order nibble, the second is drawn using the color in the low-order nibble, the third is drawn with the color in the high-order nibble, and so on, until all the pixels specified by the first byte have been drawn.

	Definition of Computer display standard
		They are often a combination of display resolution (specified as the width and height in pixels), colour depth (measured in bits), and refresh rate (expressed in hertz).
		XGA supports a resolution of 1024×768 pixels with a palette of 256 colours (8 bits per pixel), or 640×480 with high colour (16 bits per pixel).
		Other display modes are also defined as VGA, such as 320 × 200 at 256 colors (8 bits per pixel) and a text mode with 720 × 400 pixels.

	Color Depth
		As usual color depth is measured in bits which a required to represent one color value (pixel) - bits per pixel (bpp).
		These pixel format are not wide-spread nowadays, but some file formats allows to store them.
		The problem is when we apply some operations on the 8 bit per channel image (for example tone adjustment or color enhancement), some color information can be lost or distorted due roundoff errors.

		That corresponds to 24 bits per pixel, but a 24-bit-per-pixel image takes three times as much memory as an 8-bit-per-pixel image.
		If it finds a pixel that has the value 5, it looks at color #5 in the table, and sends that RGB value to the screen.
		These are 15 or 24 bits per pixel, but use RGB values directly instead of a color table.

	Promoting Z Buffers to 32 Bits Per Pixel (Site not responding. Last check: 2007-09-19)
		A display driver whose display device does not support rendering to z and color buffers with differing pixel depths must transparently promote a 16 bits per pixel (bpp) z buffer to 32 bpp in order to render both the z buffer and a 32 bpp color buffer at the same time.
		In this case, the driver allocates a 32 bpp z buffer in place of the requested 16 bpp z buffer.
		Any z format whose depth stencil does not occupy the same number of bits per pixel as the color buffer (in other words, mismatching z and stencil surfaces).

	Visuals and Colormaps
		Each pixel consists of some fixed number of bits; pixels are mapped to visible colors in a hardware-dependent way.
		Take an eight bit display, for example: eight bits are not enough to encode a color in-place; only a few arbitrary RGB values would be possible.
		Instead, the bits are interpreted as an integer and used to index an array of RGB color values.

	Graphic File Formats
		By defining the file format it may be possible to determine the number of bits per pixel and additional information.
		A 16 bits per pixel image will be up-graded to 24 bits per pixel, and a 32 bits per pixel image will be down-graded to a 24 bits per pixel image.
		This procedure will not affect the image since the 8 extra bits of a TGA 32 bits per pixel file are used to store Alpha or transparency information.
