Abstract:
An image signal processing apparatus includes a down-converter unit configured to down-convert an image signal having a first resolution into an image signal having a second resolution lower than the first resolution, a high-frequency-band-edge detection unit configured to perform filtering on the image signal having the first resolution to extract components in a higher frequency band than a frequency corresponding to the second resolution and to perform down-conversion on an edge detection signal obtained through the filtering to obtain an edge detection signal having the second resolution, and a combination unit configured to combine the edge detection signal obtained by the high-frequency-band-edge detection unit with the image signal having the second resolution generated by the down-converter unit so as to obtain an image signal having the second resolution and being to be displayed.

Claim (Index 15):
The image signal processing apparatus according to  claim 1 , wherein assuming that a down-conversion ratio is N:1, N being an integer of 2 or more, the down-conversion performed by the one or more processors includes dividing the high frequency band edge signal obtained through the filtering process into units of 2N pixels, generating continuous 2N sets of two pixels from high frequency band edge signals corresponding to 2N pixels of each division unit and a first pixel of a next division unit following said each division unit, the 2N pixels and the first pixel being continuous, and extracting, from the 2N sets, a set of two pixels having the largest absolute difference.
