Abstract: There is provided an imaging device including an imaging element that acquires a captured image of a subject, a light emission unit that emits light to the subject, and a control unit that is capable of controlling a timing of exposure performed by the imaging element and a timing of light emission performed by the light emission unit. In a mode in which imaging is performed with a plurality of times of consecutive light emission by the light emission unit, the control unit controls at least one of a timing of the exposure and a timing of the light emission so that light amounts effective for exposure in each imaging are substantially the same.

Abstract: An image processing apparatus includes an acquiring unit that acquires stability state information for an image capturing apparatus indicating whether the image capturing apparatus is stable or not, and a processor that rotates an image, captured by the image capturing apparatus, based on the stability state information of the image capturing apparatus.

Abstract: A control device includes: a detection section configured to detect setting to a predetermined imaging mode; and a control section configured to set a predetermined method of zooming in response to the setting to the imaging mode, and to perform zoom control with a subject distance fixed.

Abstract: In order to propose a signal input and output apparatus for changing over control depending on a detection result by discriminating the type of signals when signals of two or more types are passed in the same signal line, a signal input and output apparatus comprises signal discrimination changeover means for discriminating the type of control signal through cable, plug and jack, as a transmission path generating a discrimination signal, supplying it to a controller, and changing over the control of a signal processor to the controller on the basis of the discrimination signal, and thereby input and output of plural control signals can be processed through a single transmission path. As a result, by a single jack only, plural signals can be passed on the same transmission path by optimizing the transmission and reception paths and transmission and reception elements, and therefore the parts mounting area can be saved, and states of various types of signals can be detected.

Abstract: 1-Substituted-9H-pyrido[3,4-b]indole derivatives, which are further optionally substituted in the 3- or 4-position, are inhibitors of xanthine-oxidase. A representative embodiment is 1-formyl-4-hydroxy-9H-pyrido[3,4-b]indole which can be prepared through the processing of Picrasma quassioides.
