When I click one photo, then camera take lot of time to get ready for second photo

Most of the time, when a camera asks to shut down there is a problem with the camera. Could be the lens can't come out complete or other, almost invisible things. Even the battery can be a bit low, so as soon as it wants to make the camera ready to "shoot" the voltage goes low. Lots of cameras, will go off then. If you can't find any obstruction on the lens, please charge the battery and try again.

I also encountered this problem and found out that this was due to camera not being ready for the next image and click at this time will cause reading problem. Secondly, this might be due to low battery while taking picture.

check your shuther speed, you may be moving the camera to soon once you click the photo most slr's you need to wait 3 seconds before moving the camera after you click, make sure your focus is also clear b4 you click also

THE PAUSE TIME YOU ARE TELLING IS THE TIME TAKEN BY CAMERA TO READY AGAIN. YOU CAN NOTICE THAT WHEN YOU SHOOT PHOTO WITHOUT FLAST/OUTDOOR IN DAY TIME THAN IT DO NOT TAKES TIME PAUSE. WHEN CAMERA USES FLASH IT WILL TAKE TIME TO BE READY FOR NEXT SHOOT. IT IS NORMAL

auto you mean timer function? that will take your picture after 3, or 5 or 10 seconds?

to use it go to the menu setting of your camera and search for self timer, auto timer or something similar.
then select a desired time (ie. 5 seconds) and click ok.
then click to take a photo. the timer will start and after 5 seconds the photo will be taken

According to your description, I would like to assume that your camera takes 9 seconds to get the flash ready, not to focus. If it is the focus problem, you need to send the camera for realignment or to replace the lens.
Here is my suggestion:
Try to disable the flash. Does it still take 9 seconds to take picture? If the answer is ‘no’, then try to use fully charged batteries or new batteries to reduce the flash charging time.
If you have a ‘batteries drain quickly’ issue as well, this tip may help: Why my camera keeps saying ‘change battery’ even with new batteries?

Its all relative. With most of these compact cameras, to conserve power, the camera does not always keep the flash ready to fire at any given second. Firing the flash uses a lot of juice, so if it was always at the ready, the battery life would be reduced to half or less, which would would cause more problems.

When you press the button the camera then tries to cycle up enough flash power that it thinks it will need to light the scene correctly. This will require less time if its in the day and longer if its dark.
Add more time if the battery life is low.

Once you fire the flash and exhaust all the reserve power from the buffer, the camera will need to recycle itself to garner enough power for another flash, this again adds time.

More expensive cameras have better power management and can cycle up faster.

Now its camera . its not working at all. when we click on camera an error message is shown. " camera module not ready" . please help me by providing your answer to this problem..m

some have a view button which you can choose to put in "black mode". happens a lot. take it to your local camera shop if they know anything they should be able to put it right in seconds

I found that a large memory card will make the "warm up" time longer. If you use a smaller memory card, this will not be the case.
