Control device
When performing inspection of a tip of a suction nozzle, the tip of the suction nozzle is imaged, and an opening of the tip of the suction nozzle is identified based on the image data. With the image based on the image data, locations with less than a set brightness level inside a location with the set brightness level and greater is identified as the opening. The identified opening is divided into four regions by boundary lines, and the area of the opening is calculated for each of the regions. Based on the areas calculated for each region, it is determined whether the suction nozzle is good. By determining whether the suction nozzle is good based on the area of the opening for each region, it is possible to reliably determine whether the suction nozzle is good. |

Video encoding and decoding
A temporal motion vector predictor is includable, together with one or more spatial motion vector predictors, in a set of motion vector predictors for a block to encode of a current frame. A method of determining the temporal motion vector predictor comprises selecting as the temporal predictor one motion vector from among motion vectors in a reference block of a reference frame different from the current frame. The reference block is a block of the reference frame collocated with the block to encode or a block of the reference frame neighboring the collocated block. The selection is based on a diversity criterion for achieving diversity among the predictors of the set. This can reduce the motion vector memory requirements with no or no significant additional coding efficiency penalty. Alternatively, even if the motion vector memory is not reduced in size, coding efficiency improvements can be achieved. |
