Original Abstract Submitted
According to an aspect, a detection device includes: a plurality of optical sensors arranged in a detection area; a light source configured to emit light to the optical sensors; an analog front-end (AFE) circuit configured to acquire a detection value of each of the optical sensors; and a signal processing circuit configured to acquire predefined biometric information based on first time-domain data obtained by acquiring the detection values in chronological order. The signal processing circuit is configured to: convert the first time-domain data into a time-domain matrix and perform singular value decomposition on the time-domain matrix, and inversely calculate second time-domain data based on a predetermined singular value among a plurality of singular values obtained as a result of the singular value decomposition; and acquire the biometric information that changes in chronological order as image information using the second time-domain data.
