Hi everyone

Could anyone help me to obtain 24 bit RGB format from the output of ADC from image sensor

THANKS

what's the ADC image sensor output format?
YUV? RGB?
There are quite simple formulas to translate from one color format to another, so it shouldn't be much trouble. Just look into sensor documentation what type of output data it sends and (if needed) do the conversation to 24bit RGB color.
You will find tons of ready to use functions on internet regarding translation between color formats.

Thanks MirekCz
for replay

the output of ADC from sensor is 8 bit RGB

i need circuit for that or code

Hello alzhrani,

If the sensor has got one output for each colour (RGB = red, green, blue) than you have 24 bit RGB already:

8 bit red, 8 bit green, 8 bit blue = 24 bit RGB

What is "8 bit RGB"?
Do you mean 3 bits of red, 3 bits of green, and 2 bits of blue?
Or do you mean that it outputs three 8-bit bytes in sequence, first red, then green, then blue?

thanks for every body

no i mean the output of the sensor are RGB bayer Patttern

and i would like to make interpolation fore that matrix to get 24 bit RGB

hi alzhrani,
The demosaic algorthem is you want.
You can search google by "demosaic" or "color interpolation".
The following is weblink, I search from google.
