Abstract
A reproducing apparatus to reproduce a captured moving image includes a filter circuit that obtains a capturing condition (shutter speed information “s”) of frames constituting the moving image. The filter circuit smoothes pixel information of the frames by using a parameter (directional smoothing filter kernel) according to the obtained shutter speed.
Claims18
A reproducing apparatus comprising:
- an acquiring unit configured to acquire a data stream including moving image data;
- an extracting unit configured to extract shutter speed information used when the moving image data is captured by a capturing apparatus, from the data stream acquired by the acquiring unit;
- a filtering unit configured to generate filtered moving image data based on performing smoothing filter processing on the moving image data by using the extracted shutter speed information such that the moving image data included in the data stream are smoothed more strongly in a case where shutter speed information extracted by the extracting unit corresponds to a shutter speed higher than a threshold of speed than a case where shutter speed information extracted by the extracting unit corresponds to a shutter speed lower than the threshold of speed;
- and
- an outputting unit configured to output the filtered moving image data for displaying.
A reproducing method comprising:
- acquiring a data stream including moving image data;
- extracting shutter speed information used when the moving image data is captured by a capturing apparatus, from the data stream acquired by the acquiring step;
- generating filtered moving image data based on performing smoothing filter processing on the moving image data by using the extracted shutter speed information such that the moving image data included in the data stream are smoothed more strongly in a case where shutter speed information extracted in the extracting step corresponds to a shutter speed higher than a threshold of speed than in a case where shutter speed information extracted in the extracting step corresponds to a shutter speed lower than the threshold of speed;
- and
- outputting filtered moving image data on which the filter processing is performed in the performing step, as moving image data to be reproduced.
A non-transitory computer-readable storage medium storing a computer-executable process, the computer-executable process causing a computer to perform a method of reproducing a captured moving image, the method comprising:
- acquiring a data stream including moving image data;
- extracting shutter speed information used when the moving image data is captured by a capturing apparatus, from the data stream acquired in the acquiring step;
- generating filtered moving image data based on performing smoothing filter processing on the moving image data by using the extracted shutter speed information such that the moving image data included in the data stream are smoothed more strongly in a case where shutter speed information extracted in the extracting step corresponds to a shutter speed higher than a threshold of speed than in a case where shutter speed information extracted in the extracting step corresponds to a shutter speed lower than the threshold of speed;
- and
- outputting filtered moving image data on which the filter processing is performed in the performing step, as moving image data to be reproduced.
