20130307797 | TABLET TERMINAL AND RECORDING MEDIUM - A tablet terminal receives a triggering indication to enable a detection result of eye gaze, and sets a target area in which the presence of a target object is assumed on a screen of a touch panel using a detection position of eye gaze. The tablet terminal further displays a partial image displayed in the target area out of an image displayed on the screen in an aiming area in which a touch operation to the target area is received in place of the target area, and records a correspondence relation between coordinates of the aiming area and coordinates of the target area. When a touch operation is received within the aiming area, the tablet terminal converts the coordinates of the aiming area in which the touch operation is received into the coordinates projected to the target area using the correspondence relation recorded, and then outputs the converted coordinates. | 11-21-2013 |

20080263430 | Data readout device and data readout method - A data readout device generates decoded data based on a decided data bit decided by performing a hard-decision on likelihood data, wherein the likelihood data is generated in accordance with an iterative decoding method corresponding to a turbo-coding process. The iterative decoding process is performed on a sampled value obtained by sampling a signal read out from a magneto-optical disk at a predetermined sampling period. The data readout device is made up of a reliability determination part and an error correcting decoder. The reliability determination part detects whether each obtained data bit was obtained from likelihood data within a predetermined range defined with respect to a histogram of log likelihood ratios. When it is detected that a data bit was obtained by a hard-decision on likelihood data within the predetermined range, the data bit is regarded as being obtained by a hard-decision whose reliability is not sufficient. In this way, the error correcting decoder can perform ECC-based decoding operations including loss-correction processes depending on respective reliability-determination results that distinguish reliabilities among respective data bits. Thus, the accuracy of decoded data is increased. The data transfer rate of transferring decoded data when reading out of the MO medium is also improved to the utmost. | 10-23-2008 |
