    • An exemplary shading detecting method for a camera module is provided. In the method, a plurality of brightness values are measured from a plurality of predetermined regions of a stable rectangular image generated by the camera module. A plurality of brightness differences, each based on a comparison between a respective two of the brightness values, chosen from among the brightness values measured, are calculated. Each brightness difference is judged as to whether it exceeds a corresponding predetermined threshold. If at least one brightness difference is judged to exceed the corresponding threshold, the camera module is a rejected. A corresponding shading detecting apparatus, for facilitating the shading detecting method, is also provided.
    • 提供了一种用于相机模块的示例性着色检测方法。 在该方法中,从照相机模块生成的稳定矩形图像的多个预定区域测量多个亮度值。 计算出从所测量的亮度值中选择的相应的两个亮度值之间的比较的多个亮度差。 判断每个亮度差是否超过相应的预定阈值。 如果判断出至少一个亮度差超过相应的阈值,则相机模块被拒绝。 还提供了一种用于促进阴影检测方法的相应的阴影检测装置。

    • A method for preventing a TOC reading error in a multi-session disc includes determining a range of absolute time of a specific session, when a plurality of Q codes, each of which has a value in a “POINT” item not equal to B0, are read, determining whether each of the plurality of Q codes is located in the range of absolute time according to an absolute time of each Q code, and when a first Q code having a value in the “POINT” item equal to B0 is read, reading a second Q code that has a value in the “POINT” item not equal to B0 again, and determining whether the absolute time of the second Q code is within the range of absolute time.
    • 一种用于防止多会话盘中的TOC读取错误的方法包括:当多个Q代码中的每一个具有不等于B0的“POINT”项中的值时,确定特定会话的绝对时间的范围, 被读取,根据每个Q代码的绝对时间确定多个Q代码中的每一个是否位于绝对时间的范围内,并且当读取具有等于B0的“POINT”项中的值的第一Q代码时 读取在“POINT”项中的值不等于B0的第二Q码,并且确定第二Q码的绝对时间是否在绝对时间的范围内。
