1. A liquid crystal display apparatus configured to display an input image signal using a liquid crystal display element, the liquid crystal display apparatus comprising:

  • a feature amount generator configured to generate a feature amount based on the number of pixel pairs that satisfy a correspondence relationship between a gradation value of a target pixel and a gradation value of a surrounding pixel around the target pixel for an image represented by the input image signal;

    a processor configured to provide processing so as to set a correction value that reduces a dynamic range of a gradation value of the input image signal when the feature amount is larger than a first threshold, and so as not to set the correction value when the feature amount is equal to or smaller than the first threshold; and

    a liquid crystal driver configured to drive the liquid crystal display element based on the input image signal that has been corrected by the correction value.
