24 bits/pixel: one byte for red, one byte for green, one byte for blue.
the Bit depth
Pixel depth refers to the number of bits used to represent the color of each pixel in a digital image. It determines the range of colors that can be displayed in an image. A higher pixel depth allows for more colors and greater color accuracy, while a lower pixel depth may result in color banding or a limited color palette.
In RAM it occupies 1500x1000x3 bytes (8bit = 1 byte). The final file size depends on the format in which it is saved on the disk.
Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.
In a bitmap, information is stored as a grid of pixels, where each pixel represents a specific color. The bitmap uses a matrix of bits, with each pixel typically requiring multiple bits to define its color, depending on the color depth (e.g., 1-bit for black and white, 8-bit for 256 colors, or 24-bit for true color). The arrangement of these bits in the grid corresponds to the image's dimensions, allowing for the representation of detailed graphics. Additionally, bitmap files may include metadata, such as image size and color profiles, stored in a header.
A hui tebe, sosni!! Lol!!
A bitmap is a series of bits which represents a rasterized graphic image, each pixel being represented as a group of bits.
bit depth
One byte For each primary color results in 256 different intensity levels for each primary color. Thus a pixel can take on a color from 256X256X256 or 16.7 milion possible choices. If 1 bit = 256 Color Approximately. Then in 24 bit = 256 X 24 = 6144 color Approximately. Answer is Given By Pranjal Nath From Assam Bsc It(5th Sem) From Kuvempu Univercity. India.
A gif or Graphics Interchange Format file can be made with any of a great number of image manipulation programs. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to 256 distinct colors. The colors are chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.
In RGB color model, each color element (Red, Green, Blue) is assigned 8 bits, for a total of 24 bits. This allows for 256 possible shades of each color (2^8 = 256).
RGB 8 color format uses 8 bits for each color channel (red, green, blue), allowing for 256 shades per channel. RGB 16 color format uses 16 bits for each channel, providing a wider range of colors with 65,536 shades per channel. This means RGB 16 can display more detailed and accurate colors compared to RGB 8.
