The following commands can be used to take a screenshot.

adb shell /system/bin/screencap -p /sdcard/screenshot.png
adb pull /sdcard/screenshot.png screenshot.png

Source

Update: After some research I've noticed a similar question that has an answer that might help you:

If the slow part is raw to png conversion (time adb shell screencap -p /sdcard/x.png is considerably slower than time adb shell screencap /sdcard/nonpng.raw, as I have it in games)

This shell script by max_plenert is a better example:
adb shell screencap /sdcard/mytmp/rock.raw
adb pull /sdcard/mytmp/rock.raw
adb shell rm /sdcard/mytmp/rock.raw

// remove the header
tail -c +13 rock.raw > rock.rgba

// extract width height and pixelformat:
hexdump -e '/4 "%d"' -s 0 -n 4 rock.raw
hexdump -e '/4 "%d"' -s 4 -n 4 rock.raw
hexdump -e '/4 "%d"' -s 8 -n 4 rock.raw

convert -size 480x800 -depth 8 rock.rgba rock.png

What size is the screenshot? – Oceans Oct 01 '15 at 09:28
size of my phone: 1080x1920, using this command I can't change the size of the screenshot? – Sabrine Moumni Oct 01 '15 at 09:30
I meant the size of the file. And what time are you measuring, the time it takes to pull or the time to actually take it? – Oceans Oct 01 '15 at 09:31
the size of the file is 1,96 Mo , i'm measuring the time to take the screenshot – Sabrine Moumni Oct 01 '15 at 09:33
I updated the answer. I suggest checking out the source as well. – Oceans Oct 01 '15 at 09:48
the command convert is unkown on my phone , I should do everything on phone not on pc, even the screenshot I can keep it on phone – Sabrine Moumni Oct 01 '15 at 09:52
I test the command ffmpeg, on my pc it gives a screenshot with wrong colors , on my phone it doesn't work at all – Sabrine Moumni Oct 01 '15 at 10:10
where is the file that I should add to my phone, so that it can know the command ffmpeg, I think it's a sh file – Sabrine Moumni Oct 01 '15 at 13:18
