Image signal processing apparatus, image signal processing method, recording medium, and integrated circuit

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.
