Consider a 3 different raster system with resolutin of 64048012801024 and 25602048 what size frame buffer is needee for each of theae system tostore 12 bits and 24 bit?
to store 12 bits per pixel 1.for system with resolution 640 by 480 frame buffer size=(640*480*12)/8=0.46Mbyte 2.for system with resolution 1280 by 1024 frame buffer sizs=(1280*1024*12)/8=1.96Mbyte 3.for system with resolution 2560 by 2048 frame buffer sizs=(2560*2048*12)/8=7.86Mbyte to store 24 bits per pixel 1.for system with resolution 640 by 480 frame buffer size=(640*480*24)/8=0.92Mbyte 2.for system with resolution 1280 by 1024 frame buffer sizs=(1280*1024*24)/8=3.93Mbyte 3.for system with resolution 2560 by 2048 frame buffer sizs=(2560*2048*24)/8=15.72Mbyte
What is Random access frame buffer?
A frame buffer temporarily stores an entire image frame for image or video capture applications. Here, 'buffer' implies 'temporary memory'. 'Random access' means that an interfacing microprocessor or other electronic component can read from ('access') arbitrary ('random') memory locations. Given that this is in the context of a frame buffer, that means you could read the first pixel, then the pixel on the 10th row and 9th col, then the last pixel, or any order desired. This is in contrast to 'sequential access', which only allows reading consecutive memory locations (ie read pixel1, then pixel 2, pixel3, ...). Hopefully it is clear that random access allows for more control and is necessary for image processing operations. On the other hand, sequential access gives less control, but is sufficient for transferring an image frame to memory or from camera to LCD display. To be clear, 'random' here means 'arbitrary', and is also used to describe the general-purpose random access memory (RAM) in PCs.
How many KB is 1 Pixel?
On a Windows Vista system, the size of one pixel is 631 bytes, however, the size on disk is 4 KB, or 4,096 bytes. Hope this helps.
What is depth buffer method?
The Z-buffer algorithm is a convenient algorithm for rendering images properly according to depth. To begin with, a buffer containing the closest depth at each pixel location is created parallel to the image buffer. Each location in this depth buffer is initialized to negative infinity. Now, the zIntersect and dzPerScanline fields are added to each edge record in the polyfill algorithm. For each point that is to be rendered, the depth of the point against the depth of the point at the desired pixel location. If the point depth is greater than the depth at the current pixel, the pixel is colored with the new color and the depth buffer is updated. Otherwise, the point is not rendered because it is behind another object.
Describe Mpeg i p b frames storage size?
Taken from http://bmrc.berkeley.edu/frame/research/mpeg/mpeg_overview.html The typical data rate of an I-frame is 1 bit per pixel while that of a P-frame is 0.1 bit per pixel and for a B-frame, 0.015 bit per pixel.
How frame buffer can be used to control the color and intensity of the picture display?
The data from the framebuffer determines which of the colors in the palette are used for the current pixel it is rendering. This output data provides primary-color data from the lookup table.
Suppose an RGB raster system is to be designed using an 8 inch by 10 inch screen with resolution of 100 pixels per inch each direction.If we want to store 6 bits?
In an RGB raster system; The size of screen =8 inch by 10 inch Resolution of each direction =100 pixels per inch To store 6 bits per pixel; The resolution of the system =8* 100 by 10 *100 From buffer size = to store bits per pixel* resolution = 6 * 800 *1000 bits = 6 * 800 *1000 bytes 8 = 6 * 800 *1000 K bytes 8*1024 = 585.9 K bytes = 0.57 M bytes
A cheap digital webcam has a 1000 x 2000 pixel image resolution for still images and uses a 24-bit colour scale for each pixel How many bytes of memory space would be needed to store a single image in?
1000 x 2000 x 3 = 6.0 million bytes, or 5.722 MB.
How many pixels in HD?
There are several different formats of HD. The one used most widely is 1080 x 1920. Multiply the number of lines by the number of pixels per line and you get 2073600 pixels per frame. Each pixel requires 3 bytes to display 24 bit colour so there are 6220800 bytes per frame. (broadcast equipment uses more bits per pixel). Note that the number of pixels is per frame, so a 1080i (interlaced) image will have the same number of pixels but will use two separate fields to display them. Finally, as there are 29.97 frames per second (US standard) a full HD image will need around 186 megabytes per second for full quality moving video.
How long would it take to load a 640400 frame buffer with 12 bit per pixel It 106 bits can be transferred per second?
That's going to depend on how many pixels have to be loaded, which the question neglects to specify. The number of seconds required will be 0.1132 times the number of pixels.
