摘要： In an image display device of at least one embodiment, a regional maximum detection section detects an areal maximum pixel luminance (regional maximum) on the basis of an input image. A regional mean calculation section calculates an areal mean pixel luminance (regional mean) on the basis of the input image. A data comparison section compares a control determination threshold retained in a control determination threshold storage section with the regional maximum for each area, and outputs a comparison result for that area. An LED output value calculation section sets a value corresponding to the regional maximum as an LED output value for each area with the regional maximum greater than the control determination threshold, and sets a value corresponding to the regional mean as an LED output value for each area with the regional maximum less than or equal to the control determination threshold.

摘要： A signal processing device (201) includes noise reduction units (101), cascade-connected to each other, each of which includes: a signal selection section (31) for selecting a representative value from sampled signals obtained from an input signal by sampling a target signal and signals which are away from the target signal by given intervals; a voltage determination section (51) for determining which of a determined representative value and a voltage of the target signal is larger; and a signal output section (61) for increasing or decreasing the voltage of the target signal depending on a result of the determining and outputs the target signal as the output signal. A combination of intervals between the target signal and the signals excluding the target signal vary from noise reduction unit (101) to noise reduction unit (101). A noise reduction unit on a more upstream side has a larger maximum value of the intervals.
