Black out correction device |
摘要 |
A black out correction device according to the present invention comprises a correction level storage, a comparator and a selector. The correction level storage memorizes a signal level equal to an original signal level of a sampled signal outputted from an image sensing device when a black out is generated in a video created based on the sampled signal as a high-brightness clamping level. The comparator compares the signal level of sampled signal to a reference level for judging whether or not the black out is generated. The selector selects and outputs the high-brightness clamping level when a result of the comparison by the comparator shows that the signal level falls below the reference level, while selecting and outputting the sampled signal when the comparison result shows otherwise.
