Abstract:
A depth signal generation apparatus includes a depth signal estimation unit, a depth signal histogram generator, and a depth signal level converter. The depth signal estimation unit estimates a depth signal for each pixel of a predetermined unit in a video image signal. The depth signal histogram generator divides a range of a depth signal level which the depth signal can have, into depth signal level regions each having a predetermined range size, determines which depth signal level region includes the depth signal for each pixel, counts the number of pixels included in each depth signal level region to generate depth signal histogram data according to the count value. The depth signal level converter generates a depth signal level conversion curve according to the depth signal histogram data and generates a depth signal after level conversion by executing depth signal level conversion according to the depth signal level conversion curve.
