There is provided a navigation device including an image sensor, an analog to digital converter and a processor. The image sensor is used to output an analog image using an exposure time. The analog to digital converter is used to convert the analog image to a digital image using a resolution. The processor is used to identify an image quality of the digital image, and adjust at least one of the exposure time of the image sensor and the resolution of the analog to digital converter according to the image quality thereby adjusting the operation power by changing data length actually processed by the processor. 一种导航装置，包含图像传感器、模拟数字转换器以及处理器。图像传感器以曝光期间输出模拟图像。模拟数字转换器以分辨率将所述模拟图像转换为数字图像。处理器判断所述数字图像的图像质量，并根据所述图像质量调整图像传感器的所述曝光期间及模拟数字转换的所述分辨率至少其中一者，藉以通过改变处理器实际处理的数据长度来调整运算耗能。
