Abstract: An image pickup apparatus that is capable of preventing degradation of quality of an image obtained. An insertion-extraction unit inserts and extracts a filter of which transmittance for infrared light is higher than the transmittance for visible light. A computation unit computes an object distance between the image pickup apparatus and an object. An evaluation unit evaluates an image quality based on at least a sharpness in an image including a picked up object image. A control unit controls the insertion-extraction unit so as to insert or extract the filter based on at least one of the image quality and the object distance.

Abstract: An imaging apparatus to communicate with an external apparatus via a network includes an image capturing unit, a rotation unit, a reception unit, first and second control units, a determination unit, and a control switching unit. The rotation unit rotates the image capturing unit in a predetermined direction. The reception unit receives a control command including information for designating acceleration when the rotation unit rotates the image capturing unit. The first control unit controls the rotation unit at the designated acceleration. The second control unit controls the rotation unit at acceleration that is different from the designated acceleration. The determination unit determines whether a speed at which the rotation unit rotates the image capturing unit is within a predetermined range. The control switching unit switches between the first control unit and the second control unit according to a determination result of the determination unit, and control the rotation unit.

Abstract: A 3D image display has a display unit which is driven so as to emit light in a line-sequential or a block-sequential manner; a storage unit which stores characteristics information relating to temporal change in transmittance of a liquid crystal shutter glasses with respect to light of respective primary colors in the display unit; and a correction unit which corrects an input image signal of the respective primary colors using the characteristics information, so as to reduce color fluctuation between lines or between blocks in the observed image caused by differences in the temporal change of the transmittance of the liquid crystal shutter glasses in respect of each of the primary colors, wherein the display unit displays a corrected image based on a corrected image signal generated by the correction unit.

Abstract: At least one image capturing apparatus communicating via a network with an external apparatus can insert and remove an infrared light cut filter to and from an optical path of an image-capturing optical system of the image capturing apparatus, and when a setting value of a communication protocol describing a brightness value of brightness of a subject and a delay time for determining the brightness and describing the brightness value and the delay time for the insertion and removal of the infrared light cut filter is received from the external apparatus via a network, then a determination is made as to whether the setting value matches a setting value suitable for another protocol, and when the setting value does not match the setting value suitable for another protocol, the setting value including the brightness value and the delay time is converted into a setting value suitable for another protocol.

Abstract: A 3D image control apparatus receives from shutter glasses an identification signal for identifying a type of the shutter glasses, reading a shutter opening and closing characteristic of the shutter glasses of the type identified based on the identification signal from a storage unit storing shutter characteristics of the shutter glasses in association with the type of the shutter glasses. The 3D image control apparatus controls display timing of an image display unit based on the shutter opening and closing characteristic in such a manner that display periods of the right eye image and the left eye image are respectively within opening periods of the right shutter and the left shutter.

Abstract: A crosstalk image signal is generated by multiplying an image signal in a subsequent display period of a correction target image signal by a coefficient which is set corresponding to a vertical position on a display screen of a display apparatus in a descending order from the top, or multiplying an image signal in a previous display period of the correction target image signal by a coefficient which is set corresponding to the vertical position on the display screen in a descending order from the bottom. Then the crosstalk image signal is subtracted from the correction target image signal.

Abstract: Serration rolling tools and thread rolling tools each having groups of leading teeth, finishing teeth and disengaging teeth are provided, a lead angle of the thread rolling tool being set in accordance with the rolling diameter of the serration section in a work piece. The thread rolling tool and serration rolling tool are arranged parallel and integrally. First a rolling operation for forming serrations is started by the serration rolling tools, a rolling operation for forming threads being started by the thread rolling tools in the course of the rolling operation by the group of the leading teeth of the serration rolling tools. A rolling operation for finishing the threads is completed in the latter half of the rolling operation by the group of the finishing teeth for the serrations. The difference in rolling diameters is absorbed by the slide of the aforesaid thread rolling tools on a shaft member (work piece), thus enabling the simultaneous formation of serrations and threads in a short rolling stroke.
