The max. value SBL 1 of the clip value which can prevent the generation of the false color is outputted when the color temp. is low. The max. value SRL 0 of the clip value which can prevent the generation of the false color is outputted if the color temp. is about middle. The max. value SRL 2 of the clip value which can prevent the generation of the false color is outputted when the color temp. is high. The dynamic range of the color signals is expanded in this way without generating the false color.

Title: Arrayed antenna
Inventor: YAMAMOTO HIROHIKO
IPC: H01P5/16
Filed: 1991-11-27
Abstract: PURPOSE:To obtain the directive array antenna with a high efficiency and a high gain in which a prescribed gain is obtained over a wide angular range by specifying the arrangement and the excitation of element antennas. CONSTITUTION:Element antennas 8 exciting an equal amplitude and an equal phase are arranged to an array central part and element antennas 8 having the exciting distribution offering prescribed gain over a wide angular range are arranged to an array peripheral part. Since the element excitation distribution is close to the equal amplitude equal phase excitation by selecting a side lobe level at uniform excitation to be an object for deciding the exciting distribution, the phase error and the amplitude error or the like are reduced in the vicinity of a main beam and the efficiency is increased. In the case of a plane array, a beam between a shaped beam and a beam in the case of uniform excitation is formed by arranging the elements of the equal amplitude and equal phase in the vicinity of the middle part of the antenna. Thus, a very flat main beam is obtained even when extremely ununiform exciting distribution is not taken.
