Abstract: Provided are a gas detection device, an information processing device, and a program which enable a user himself/herself to easily determine whether a gas leak has occurred. The gas detection device includes: a first imaging section configured to capture an image of an inspection region in an infrared region; a second imaging section configured to capture an image of the inspection region in a wavelength range that is not influenced by light absorption by gas; and a hardware processor configured to perform image processing for detecting a gas in a first image captured by a first imaging section, and to perform control to simultaneously display various types of images on a display section from a display target image group including the first image, a second image captured by a second imaging section, and a third image subjected to the image processing.

Abstract: Provided are a gas detection device, an information processing device, and a program which enable a user to accurately estimate a gas leak position. The gas detection device includes a hardware processor that causes a display screen to display a first image captured by a first imaging section and a second image captured by a second imaging section, and changes at least one of a first display position of a specific position included in the first image and a second display position of the specific position included in the second image on the display screen. The hardware processor causes the display screen to display the first display position and the second display position so that the first display position and the second display position can be compared with each other so as to recognize a difference between the first display position and the second display position.

Abstract: A lens barrel, an image pickup apparatus, a lens drive method and a method of producing a shape memory alloy used for the drive device are disclosed. A drive device includes: a lens group for guiding light from a subject; a shape memory alloy adopted to be deformed by an electricity supplied to the shape memory alloy, for moving the lens group in a direction of an optical axis; and electricity-supply controlling means for controlling an amount of the electricity supplied to the shape memory alloy; and a detecting means for detecting whether a movement of the lens group starts or not. In the drive device, a movement amount of the lens group in the direction of the optical axis is controlled based on the amount of electricity supplied when the detecting means detects the movement of the lens group.
