摘要： A control system is configured to acquire an image captured by an imaging device, and display a stereoscopic image on a display apparatus based on a position of an observer detected in a predetermined tracking area in the acquired image. The tracking area is a part of an area in which an observer is trackable and the tracking area includes a stereoscopic viewing zone in which a stereo image can be recognized from the stereoscopic image. The control system is further configured to display a stereoscopic image for a predetermined time based on a position at which the observer is detected last after the detected observer has become untrackable in the tracking area, and display a stereoscopic image suitable for a predetermined position in the stereoscopic viewing zone in a case where no observer is detected in the tracking area over the predetermined time.

摘要： An ion sensing device includes a first field-effect transistor, a second field-effect transistor, a reference electrode configured to directly contact a sample solution, a first ion-sensitive film, and a second ion-sensitive film. Each of the first field-effect transistor and the second field-effect transistor includes a semiconductor film, a bottom gate electrode, a bottom gate insulating film located between the bottom gate electrode and the semiconductor film, and a top gate insulating film. Surface materials in contact with the sample solution for the first ion-sensitive film and the second ion-sensitive films are the same. A sensitivity of the combination of the first field-effect transistor and the first ion-sensitive film is higher than a sensitivity of the combination of the second field-effect transistor and the second ion-sensitive film.

摘要： A capacitance detection circuit includes an excitation signal source configured to supply an AC driving voltage to drive the detection electrode, a high-pass filter configured to cause a current signal input from the detecting electrode to be output after being attenuated in a prescribed frequency region that is lower than a frequency of the excitation signal source, and a current signal measurement circuit connected between the high-pass filter and the excitation signal source. The current signal measurement circuit is configured to measure a current signal from the high-pass filter. The high-pass filter includes a first passive circuit element connected in series between the detection electrode and the current signal measurement circuit, and a second passive circuit element connected in series between the excitation signal source and a node between the detection electrode and the first passive circuit element.
