PROBLEM TO BE SOLVED: To prevent lowering of pulse wave detection accuracy.SOLUTION: A pulse wave detection device 100 has: a first acquisition section 112 that acquires an image of a biological object photographed by a camera 110 a biological object extracting section 113 that extracts a biological region from the image a BPF 115 that extracts a component of a frequency band which can be adopted by a pulse wave from a luminance signal representing each pixel included in the biological region a detection section 116 that detects the pulse wave from the luminance signal of the biological region from which the component of the frequency band is extracted a second acquisition section 122 that acquires luminance information concerning display of a prescribed screen and a detection controlling section 150 that uses the luminance information concerning the prescribed display of the screen to control execution/non-execution of the detection of the pulse wave by the detection section 116.
