    摘要: The present invention discloses a test method for image sharpness, which can instantly determine the sharpness of a captured image, wherein a captured image is firstly divided into multiple blocks with each block composed of multiple pixels; in each block of the captured image, the pixels having higher sharpnesses are selected, and the sharpnesses of those pixels are summed up to be the sharpness of the related block; the estimated sharpness of the captured image is also obtained similarly; and the estimated sharpness is compared with a threshold value to determine whether the captured image is sharp enough. Thereby, the present invention can test the sharpness of an image fast and correctly and inform the user of the status of the captured image and provide the user with corresponding suggestions.

    摘要: An automatic focusing system in a low-illumination setting and a method using the same are disclosed. Through a selection of the memory bits and a tone adjustment, an automatic focusing could be precisely achieved. According to one embodiment, a lens module and an image sensor are firstly used for generating the digital image signals. Next, a gain adjustment unit is introduced to adjusting the gain of the signals, so as to reduce the noises. A memory bit retrieving unit is further used to retrieve the data from a plurality of memory bits. Next, a tone adjusting process is performed to raise the signals' contrast.

    摘要: An image unsharpness test method for a camera device, wherein firstly, during the focusing stage of an electronic camera device, the image with the highest sharpness is selected to be a contrast image; next, the contrast image is compared with a captured image to obtain the sharpness difference is too great, the captured image is determined to unsharp; vice versa, if the difference is very small, the captured image is determined to be sharp. Thereby, the image unsharpness test method for a camera device of the present invention not only can determine whether a captured is sharp enough but also can reduce the photographic errors and promote photographic efficiency.
