A solid-state camera device of a horizontal charge-coupled device (HCCD) type includes a large number of CCDs arranged in a matrix to store signal charges, many rows of vertical transfer CCDs for successively reading the signal charge, a dual-line type HCCD for reading the signal charge transferred from the vertical transfer CCDs in synchronism with a horizontal transfer clock signal, an output circuit for outputting a first signal charge as the signal charge for one line transferred from the horizontal transfer CCDs in synchronism with the horizontal transfer clock signal, a band pass filter for selecting a second signal charge including noise having a band of around a frequency of the horizontal transfer clock signal from the first signal charge, a delay memory for delaying the period of the second signal charge for a required period in synchronism with the horizontal transfer clock signal, and a deduction circuit for deducting the second signal charge from the first signal charge provided by the output circuit to obtain an output signal charge not including the second signal charge.
