Abstract: A correction device including: a memory; and a processor coupled to the memory, the processor configured to: receive a modulated video signal; separate the modulated video signal into a color difference signal and a luminance signal; and in cases in which a luminance component change value in a given frequency band in a demodulated luminance signal, demodulated from the luminance signal, is a given threshold or greater, perform correction such that color difference components present in a demodulated color difference signal demodulated from the color difference signal and corresponding to the luminance components are emphasized, compared to cases in which the change value is less than the given threshold.

Abstract: The video signal combining device includes: multiple memory parts each having multiple line memories and respectively acquiring line data of video signals respectively input from multiple input terminals and sequentially writing and storing the acquired line data into the line memories, a reading control part sequentially reading the line data from any one of the line memories in a first-in-first-out manner, and a data output part outputting video combining data in which the line data read by the reading control part is connected. The reading control part reads the line data from determined one of the line memories based on a storage state of the line data in the line memories.
