Claim One:
1. An image unsharpness test method for a camera device, which applies to an electronic camera device having a focusing stage before capturing an image, comprising the following steps: receiving multiple images during said focusing stage; calculating the sharpnesses of said images received during said focusing stage, and selecting the image having the highest sharpness to be a contrast image; comparing said contrast image with a captured image to determine whether said contrast image and said captured image are of the same vision; if said contrast image and said captured image are of the same vision, comparing the sharpness of said contrast image with the sharpness of said captured image to determine whether said captured image is sharp enough; and if said contrast image and said captured image are not of the same vision, comparing a given number of said images received after said focusing stage and before said capturing stage to find out a specified image having the highest sharpness, and comparing said specified image with said captured image to determine whether said captured image is sharp enough.
