Abstract: An image pickup apparatus that can easily perform electric fine zoom adjustment, includes an image pickup section that can change an image pickup parameter, a display section that visibly displays an image signal outputted from the image pickup section, a rotational operation member that performs a change operation to the image pickup parameter, a parameter control section that controls the image pickup parameter, and a display control section that displays an effect of the change of the image pickup parameter in accordance with the rotational operation of the rotational operation member on the display section, while superimposing the effect on the image signal outputted from the image pickup section.

Abstract: An image processing apparatus includes: an evaluation value calculation unit configured to calculate a contrast evaluation value of each of first image data and second image data in which an object is imaged in a state in which auxiliary light is emitted to the object included in a first image corresponding to the first image data; a determination unit configured to determine that fog or haze is occurring at a time the contrast evaluation value of the first image data, which has been calculated by the evaluation value calculation unit, is equal to or greater than the contrast evaluation value of the second image data; and an image processing unit configured to perform image processing to the first image data or the second image data based on a determination result of the determination unit.

Abstract: An air jet for producing a filter plug for cigarette comprising an imparting portion for propelling force to a tow-like fiber bundle and a beak portion, wherein said imparting portion is constructed by a trumpet (21) having a converged tip end region, a trumpet holder (23) coaxially and encirclingly assembled on the trumpet (21) so that a primary air chamber (26a) is formed between the bodies of the trumpet and the trumpet holder, and an annular slit (29) communicated with the primary air chamber (26a) is also formed between the tip end regions of the trumpet (21) and the trumpet holder (23). An inner tube (22) is disposed coaxially in front of the assembly of the trumpet (21) and the trumpet holder (23), whereby a fiber path through which the tow-like fiber bundle is fed to a tongue of a filter plug machine is formed through the air jet along the axis thereof; the fiber bundle being accelerated by a propelling force imparted by compressed air ejected from the annular slit (29) to the fiber path.
