Abstract: A vehicular driver monitoring system includes an interior camera viewing at least a head region of a driver of a vehicle. Driver information pertaining to the driver of the vehicle is provided to an electronic control unit (ECU). Based at least in part on (i) processing at the ECU of image data captured by the interior camera and/or (ii) the received driver information, the vehicular driver monitoring system estimates a distraction workload of the driver and a driving workload of the driver. At least in part responsive to processing at the ECU of the estimated distraction workload and the estimated driving workload, the vehicular driver monitoring system determines an amount of driver attention. The amount of driver attention is determined at least in part by weighting the driving workload and the distraction workload based at least in part on driving conditions.

Abstract: The present technology relates to an image processing device and an image processing method which allow a deblocking filtering process to apply filtering appropriately. A pixel (p0i) of which the value is 255 (solid line) before a deblocking process changes greatly to 159 (dot line) after a conventional deblocking process. Therefore, a clipping process having a clipping value of 10 is performed in strong filtering, whereby the pixel (p0i) of which the value is 255 (solid line) before the deblocking process becomes 245 (bold line). Thus, a change in the pixel value occurring in the conventional technique can be suppressed as much as possible. This disclosure can be applied to an image processing device, for example.
