Abstract: An ionizer includes a discharge needle, a discharge needle holder holding the discharge needle, and a carrying air jet mechanism jetting out ion-carrying air toward a charge cancellation target. The carrying air jet mechanism is disposed at a position adjacent to the discharge needle holder, and it includes a drive nozzle having a drive air jet port, and a diffuser disposed in front of the drive nozzle with an ambient air suction gap interposed therebetween. A carrying air flow hole is formed inside the diffuser to be coaxial with the drive air jet port, and a carrying air jet port from which the carrying air is jetted out is formed at a fore end of the carrying air flow hole.

Abstract: An image processing device includes a light detection unit and an image conversion unit. The light detection unit is configured to detect a first grayscale value of a background image. The background image is an image seen by a user through an at least partially transparent display panel. The image conversion unit is configured to generate a correction image having a second grayscale value obtained by subtracting a third grayscale value pertaining to the first grayscale value from a fourth grayscale value of an input image inputted to the at least partially transparent display panel. The input image is an image intended to be displayed on the at least partially transparent display panel.

Abstract: The present invention relates to an ionizer, a static charge eliminating system, an ion balance adjusting method, and a workpiece static charge eliminating method. In an ionizer, when positive and negative voltages are applied to an electrode, an amplitude Vm of the negative voltage is set to be smaller than an amplitude Vp of the positive voltage, and further, the time Tm for which the negative voltage is applied to the electrode is set to be longer than the time Tp for which the positive voltage is applied thereto.
