ABSTRACT:
A physical quantity detecting device includes: a pixel array that has pixels two-dimensionally arranged in a matrix, each converting a physical quantity supplied from the outside into an electric signal; a driving circuit that scans, as read rows, N rows of pixels (N is an integer equal to or larger than 3) in the pixel array at the same time and reads out signals corresponding to the pixels in the read rows; and M signal processing circuit groups (1<M<N) each of which has M column circuits provided for each column of pixels of the pixel array, sequentially receives and processes signals output from the read rows, and when a scanning unit period is H, processes signals of the next read row within an average period of (M/N)H.
