Abstract: The pixel region includes a first phase difference pixel group including a plurality of the phase difference pixels of which the first side of the photoelectric conversion element is blocked by the light blocking layer in a first side region of the first side, and a second phase difference pixel group including a plurality of the phase difference pixels of which the second side of the photoelectric conversion element is blocked by the light blocking layer. The first phase difference pixel group includes a first A pixel and a first B pixel in which a light blocking area of the photoelectric conversion element using the light blocking layer is smaller than that of the first A pixel. The controller performs addition readout processing in which at least one of a pixel signal of the first A pixel or a pixel signal of the first B pixel is weighted in accordance with optical characteristics of the imaging lens.

Abstract: A received light signal of the measurement light which is reflected from the subject and is then incident on a distance image sensor is acquired from the distance image sensor and a distance image is generated on the basis of the acquired received light signal. The position of a leading end of a medical instrument inserted into the subject is acquired. A leading end position image indicating the position of the leading end of the medical instrument in the subject is acquired. A projection image which is projected to the subject and corresponds to a surface shape of a corresponding part of the subject corresponding to the position of the leading end is generated from the leading end position image, on the basis of the shape of the subject detected from the distance image and the position of the leading end. The projection image is projected to the corresponding part.

Abstract: The image blur correction device includes an acceleration sensor, an angular velocity sensor, and a system control unit. The system control unit selects one of rotation axes based on a usage state of a digital camera, and calculates a shift blur amount generated in a direction by rotation of the digital camera around a second axis and a shift blur amount generated in a direction by rotation of the digital camera around a first axis based on distances from the selected rotation axis to the acceleration sensor, angular velocities, and accelerations.

Abstract: First object candidate region extraction means extracts a first object candidate region where an object is expected to be present from an infrared light image captured by an infrared light imaging device. Second object candidate region extraction means extracts a second object candidate region where the object is expected to be present from a visible light image captured by a visible light imaging device. Score integration means calculates an integration evaluation value by performing a weighted addition of a first evaluation value in the first object candidate region and a second evaluation value in the second object candidate region. Weight decision means decides a weight in the weighted addition on the basis of, for example, an environment temperature. Object region determination means determines an object region on the basis of the integration evaluation value.

Abstract: Provided are an infrared imaging device and a signal correction method using the infrared imaging device capable of reducing noise due to a variation of pixel signals of an infrared image even in a case where the variation of the pixel signals of the infrared image is changed. An infrared imaging device includes an optical system, a detection unit that includes an effective pixel portion in which effective pixels that are infrared detection elements are arranged in a matrix form in an effective region onto which infrared rays from the optical system are incident and a reference pixel portion in which a plurality of reference pixels that are the infrared detection elements are arranged in a reference region onto which the infrared rays from the optical system are not incident, and is positioned on an imaging surface of the optical system; and a signal correction unit that performs a correction process with respect to a pixel signal detected by the detection unit. The signal correction unit performs a variation correction process of calculating a reference variation value indicating a variation of pixel signals of the plurality of reference pixels included in the reference pixel portion and reducing a variation of pixel signals of the effective pixels to become smaller as the reference variation value becomes larger.
