Hi Ymhuang, isn't so good. The patch i send to you are only for debug and break the image quality of many other reader.
Now, not all sensor have same behavior and, like as windows drivers, is necessary to implement an auto calibration of the device. Could you done one test for me ? If yes, try to increase the value of constant VFS_VAL_INFO_CONTRAST on the head of the driver to verify if image contrast of your reader change. When you find a better value send me it, logs and screenshot. Thank. Sergio Il giorno mer, 02/03/2011 alle 21.39 +0800, Yao-Min Huang ha scritto: > Hi Sergio, > > Yes, it work well.
