A new and distinct cultivar of geranium plant named Fip 469, particularly characterized by the combined features of bluish-pink, semi-double flowers with small white eyes, medium green foliage with weak zonation, vigorous growth, tall plant habit, and medium to late spring flowering response. Consistent with an embodiment of the invention, configuration and execution of a search are separated in time and location. The image quality is detected by setting a diameter of the spotlight at least in a scanning direction to the reciprocal number of a spatial frequency or smaller in which human eyesight is the most sensitive, for example, to 1000 \u03bcm or less. A first class weight and a second class weight are assigned to the first class and the second class, respectively. The switch is capable of selecting which of the trap circuit terminals to connect to which of the line reactor terminals on the basis of a level of voltage distortion being experienced by the AC source, or on the basis of a calculated level of background voltage total harmonic distortion. For the checking, a target point within a spherical phantom is represented by means of a special specimen body and the centre point of the specimen body is visibly represented by means of several image-forming methods.
