Abstract: An imaging apparatus is provided with a control unit, a noise reduction processing unit and a pixel value calculation unit. The control unit controls pulse widths of horizontal synchronization signals outputted to an imaging device such that a feed-through period and a signal period, in a case in which pixel addition in the horizontal direction is performed at the imaging device and imaging signals are outputted, are longer than a feed-through period and a signal period, in a case in which pixel addition in the horizontal direction is not performed at the imaging device. The noise reduction processing unit executes noise reduction processing to reduce the effects of noise produced in the imaging signals. The pixel value calculation unit calculates a pixel value on the basis of a first signal sampled in the feed-through period and a second signal sampled in the signal period.

Abstract: In an imaging device, a cooling unit cools an imaging element. A storage unit stores table data representing correspondence relationships between signal values based on luminescences of detection targets, cooling temperatures, exposure times, and S/N ratios. A S/N calculating unit calculates a S/N ratio at a time when pre-imaging has been performed. A determination unit determines, from the table data and as a cooling temperature and an exposure time for the imaging, a combination of a cooling temperature and an exposure time with which the S/N ratio becomes equal to or greater than the reference S/N ratio on the basis of a result of comparison between the calculated S/N ratio and a predetermined reference S/N ratio. A control unit controls the imaging element and the cooling element such that a subject is imaged at the cooling temperature and in the exposure time that are determined.

Abstract: Checkered light-intensity pixel data is acquired by shifting the sampling timing of even-numbered horizontal scan lines from the sampling timing of odd-numbered horizontal scan lines by one-half of a sampling cycle. Each of the interpolated light-intensity pixel data for the checkered light-intensity pixel data is obtained by calculating the average value of four checkered light-intensity pixel data on up-and-down and right-and-left sides of each of the interpolated light-intensity pixel data. Light-intensity image data is generated by interpolating the interpolated light-intensity pixel data into the checkered light-intensity pixel data. The data interval in the light-intensity image data becomes twice the pixel density of the checkered light-intensity pixel data.
