To provide a thermopile infrared detecting element capable of accurate temperature measurement at low cost. An infrared detecting elementusing a silicon nitride film as a first structure layerconstituting a structure of a membrane portionis provided. Unlike silicon oxide, the first structure layerhas internal stress in the tensile direction, and can thus prevent the occurrence of bending. Also, diodes Dand Dcan be formed in a silicon substrateby using the first structure layeras an element isolation region, and thus deformation of a thermopiledue to a change in the environment can be prevented to suppress measurement error of the thermopile. Furthermore, a high accuracy infrared detecting element capable of accurately detecting the temperature of cold junctions using the diodes Dand Dcan be provided.

An image processing apparatus and an image processing method are provided which are capable of changing display from a virtual space image to a real space image or vice versa, or combining them based on the movement speed of the user's point of gaze while the user is moving in a virtual space. An image processing program and a medium recording the same are also provided. In the image processing apparatus, when the movement of a head mounted display (HMD) in the virtual space is detected (Step S), the movement speed is calculated (Step S) and it is determined whether the movement speed is equal to or greater than akm/h. When the movement speed is slower than akm/h, an updated virtual space image reflecting the movement of the HMD is created for display (Steps Sand S). When the movement speed is equal to or greater than akm/h, the real image then being taken is displayed as it is (Steps Sand S).
