A CPU executes a zoom tracking control program to function as an acquisition unit that acquires a focal length of an imaging lens from a state of a zoom lens; and a control unit that performs first control of performing control to change a position of a focus lens along an optical axis direction according to the acquired focal length on the basis of a zoom tracking curve represented by tracking data representing a correspondence relationship between the focal length and a focus position according to a subject distance, and second control of acquiring contrast information representing contrast of a captured image a plurality of times during execution of the first control and performing control to change the zoom tracking curve used in the first control on the basis of a change of contrast values represented by a plurality of pieces of the acquired contrast information.

Imaging device, control method of imaging device, and control program of imaging device to change zoom tracking information based on contrast values

First and second focusing lenses Gand Gare moved to perform focusing. The second focusing lens Gis moved to a position, which is derived by a function f(x), relative to the position x of the first focusing lens G. The movement of the first and second focusing lenses Gand Gis controlled on the basis of origins that are individually set. The origin of the first focusing lens Gis detected by a first photo interrupter, and the origin of the second focusing lens Gis detected by a second photo interrupter. In a case where the first and second photo interruptersandhave mounting errors, the function f(x) is corrected on the basis of the mounting errors and the movement of the second focusing lens Gis controlled on the basis of the corrected function F(x).

When there is no parallax data for a video image overall nor is there parallax data for a main imaging subject but there is image capture condition data (to), an image capture device detects a main imaging subject () and computes parallax from the detected position of the main imaging subject (). The image capture device computes a relationship between the main imaging subject parallax and the main imaging subject distance (), adjusts parallax using this relationship so as to be in a permissible range even when image capture is performed at the image capture shortest distance (), and reproduces with the adjusted parallax (). Reproduction can accordingly be made maintaining optimum parallax when image capture has been performed whatever the parallax during image capture.

A composite eye camera has: imaging sections (A,B) that generate plural viewpoint images per frame by imaging a same subject from plural viewpoints; a three-dimensional processing section () that acquires a parallax amount on the basis of the generated plural viewpoint images; and a CPU () that judges that there is an abnormality in the parallax amount in at least one case among a case in which fluctuation of a fixed interval in the acquired parallax amount is greater than a predetermined value, and a case in which the parallax amount reaches a predetermined allowed limit value, and a case in which an object of acquisition of the parallax amount can no longer be detected, and judges that there is no abnormality in the parallax amount in a case that is none of these, and, when it is judged that there is no abnormality in the parallax amount, carries out first parallax adjustment, and, when it is judged that there is an abnormality in the parallax amount, switches to control of a second parallax adjustment, that is different than control of the first parallax adjustment, and carries out parallax adjustment. Accordingly, parallax adjustment is carried out appropriately even when there are problems in the parallax amount itself that is determined from the plural viewpoint images, or when an object of parallax adjustment can no longer be detected.

A thin-film device having the structure of a bipolar transistor is provided. The device has three thin-films formed one on another to form emitter, base and collector regions, thereby providing a NPN or PNP structure depending on the impurities contained in these thin-films. The present bipolar thin-film device is particularly useful as a phototransistor, though use is not limited only for this. A non-transparent, insulating layer having an opening may be provided to limit the passage of light and to improve the transistor characteristics.
