TLDR
In this article, the authors provided an imaging device which is capable of accurately detecting a defect even if dark current noise occurs when performing noise reduction, and preventing as much as possible reduction of an imaging dynamic range caused by an increase of the dark state noise, and a noise elimination method and noise elimination program using said imaging device.Abstract:
PROBLEM TO BE SOLVED: To provide an imaging device which is capable of accurately detecting a defect even if dark current noise occurs when performing noise reduction, and preventing as much as possible reduction of an imaging dynamic range caused by increase of dark current noise, and noise elimination method and noise elimination program using said imaging device. SOLUTION: The imaging device is provided with: an imaging signal acquisition means for acquiring an imaging signal resulting from exposure using an imaging device in a light non-shielding state; a dark state signal acquisition means for acquiring a dark state signal of the imaging device in a light shielding state; a threshold setting means for setting a threshold based on the acquired dark signal; a defect detection means for detecting a defect of an acquired dark state image based on the set threshold; a noise elimination means for eliminating noise by subtracting the dark state signal from the acquired imaging signal; and a defect correction means for correcting a signal from which noise is eliminated based on the detected defect.

TL;DR: In this paper, the authors propose an imaging device consisting of a plurality of photoelectric conversion elements which are disposed two-dimensionally and convert a subject image into an electric signal, the subject image being projected on a light receiving face from a subject, and a reading section 111 which sequentially reads electric signals for each photoelectric convert element from an element line including a plurality thereof arranged on one virtual line.

Image signal processing device and image signal processing method
TL;DR: In this article, the problem of accurate focusing fails when a threshold for determining whether a pixel has high brightness or not is a fixed value, in a device which excludes high-brightness pixels from focus evaluation value calculation objects even during photographing of a high brightness subject in order to achieve accurate focusing.

Image pickup device and image pickup method
TL;DR: In this paper, the authors proposed a method to enhance image quality by correcting a dark current and a white flaw even in the case of photographing with long time exposure, where the black level reference data obtained from all pixels are compared with a prescribed threshold and a pixel whose level is the threshold or over is discriminated to be a white fault and a storage section 5 stores its position.
