Abstract: An image testing method of an image pickup device and an image testing apparatus using such a method are provided. The image testing apparatus is in communication with the image pickup device. The image testing apparatus includes an image processing program, a multi-core processing unit and a storage unit. The image processing program is used for segmenting the main image, which is acquired by the image pickup device, into plural sub-image blocks, and transmitting the sub-image blocks to respective threads. The multi-core processing unit is used for synchronously executing the threads, thereby synchronously analyzing imaging quality of respective sub-image blocks. The storage unit is used for storing analyzing results of respective sub-image blocks. The analyzing results of respective sub-image blocks stored in the storage unit are combined together by the multi-core processing unit, thereby acquiring the imaging quality of the main image.

Abstract: A notebook computer that has a document holding function includes an upper cover and a base. The upper cover includes a screen and an image pickup device. The base includes a keyboard and a touchpad. A touchpad chassis is disposed under the touchpad and connected with a bottom surface of the touchpad. A fixing recess is formed in an edge surface of the touchpad chassis for holding the document. A rotatable frame is disposed under the touchpad for overturning the touchpad chassis. As such, a shooting angle is defined between the image pickup device and the document held in the fixing recess.

Abstract: A focus-quality judging method includes the following steps. Firstly, a comparing object including a target area is provided. A reference image pickup device is provided to shoot the comparing object to obtain a standard image including a standard target area image. Then, a first pixel number contained in the standard target area image is counted. The comparing object is shot by a test image pickup device to obtain a test image including a test target area image, wherein the test image has the same resolution as the standard image. Then, a second pixel number contained in the test target area image is counted. The first pixel number contained in the standard target area image is compared with the second pixel number contained in the test target area image. According to the comparing results, it is discriminated whether the test image pickup device performs an accurate focusing operation.
