Abstract:
1. A signal processing apparatus that is used for a liquid crystal apparatus provided with a plurality of pixels, and that processes a signal for controlling gray-scale for display of each of the plurality of pixels, the signal processing apparatus comprising: a first detection unit configured to, in the case where a first pixel is arranged between a second pixel and a third pixel, the first pixel, the second pixel and the third pixel being pixels among the plurality of pixels, detect a difference between a first gray-scale value corresponding to the first pixel and a second gray-scale value corresponding to the second pixel as a first gray-scale difference; a second detection unit configured to detect a difference between the first gray-scale value corresponding to the first pixel and a third gray-scale value corresponding to the third pixel as a second gray-scale difference; a comparison unit configured to compare the first gray-scale difference and the second gray-scale difference; and a correction unit configured to make correction of at least two of the first gray-scale value, the second gray-scale value and the third gray-scale value such that the first gray-scale difference is reduced to a third gray-scale difference smaller than the first gray-scale difference and the second gray-scale difference is reduced to a fourth gray-scale difference smaller than the second gray-scale difference, and such that the third gray-scale difference is larger than the fourth gray-scale difference when the first gray-scale difference is larger than the second gray-scale difference, and the third gray-scale difference is smaller than the fourth gray-scale difference when the first gray-scale difference is smaller than the second gray-scale difference.
