Patent
Image Processing Apparatus, Image Processing Method, and Program
TL;DR: In this article, a high-frequency component is extracted from a brightness signal for a neighboring pixel to generate the focus information on the neighboring pixel, which is then used to calculate the depth value of each pixel using a coefficient based on the illumination component.
Patent
Predictive sub-band video coding and decoding using motion compensation
TL;DR: In this article, a method and apparatus for sub-band encoding an input signal in which ringing may be diminished is presented, where filtering the of signals is done with a small number of taps with increased number of times of spectrum splitting so far made on the signals.
Patent
Subband image coding and decoding
TL;DR: In this article, the coefficients existing at the same spatial positions of the respective layers resulting from spectrum splitting are extracted for generating a coefficient tree, which is then S-scanned in a direction proceeding from the low frequency band towards the high frequency band.
Patent
Image processor and image processing method
TL;DR: In this paper, an image processor and an image processing method for compensating gradation by effectively avoiding drop of partial contrast through application to a television receiver, video tape recorder, television camera and printer or the like.
Patent

Masami Ogata,Kazuhiko Ueda +1 more
TL;DR: In this paper, an image processing method and device that uses an upsilon filter so as to properly extract borders of illuminations even when a plurality of different illuminators exist and suppresses production of an unnatural image pattern thereby realizing subjectively preferable compression of the dynamic range.
