摘要： An image signal processing apparatus performs gradation control on respective pixels. Specifically, the image signal processing apparatus includes an image signal processing unit which controls light emission and non-light emission of respective subfields so as to provide a field having a level of brightness. Here, the field is a unit display period of the pixels and divided into the subfields which have different light emission periods and are arranged in a predetermined sequence. In the predetermined sequence, the subfields are arranged in a manner such that a subfield having the shortest light emission period among the subfields is in the first place, one of a subfield having the longest light emission period and a subfield having the second longest light emission period among the subfields is in the second place, and the other one is in the third place.

摘要： An image signal processing apparatus outputs, alternately on a-per frame basis, a first image to be displayed to one of left and right eyes of a viewer and a second image to be displayed to the other eye, and transmits, to a pair of image viewer glasses, a synchronizing signal for controlling timing of opening and closing of optical filters so as to allow the viewer to see the output frames through corresponding eyes. Specifically, the apparatus includes: a persistence amount detecting unit which detects a persistence amount indicating an effect of a first frame in the first image on a second frame in the second image and immediately following the first frame; and an optical-filter adaptive control unit which generates the synchronizing signal indicating timing of opening and closing of the optical filter corresponding to the second frame. The timing is changed based on the persistence amount detected.
