A signal processing device includes a signal output circuit, a controller, and a corrector. The signal output circuit outputs a signal according to a physical quantity being input. The controller controls the signal output circuit. The corrector corrects a signal to be corrected. The signal to be corrected is output from the signal output circuit. The signal output circuit selectively performs one of first operation of outputting a characteristic signal that indicates characteristics of the signal output circuit and second operation of outputting a pseudo signal that is generated spuriously, according to control of the controller. The corrector corrects the signal to be corrected based on one of the characteristic signal and the pseudo signal output from the signal output circuit.

A data input circuit stores decoded image data into the line buffer. A transmission circuit transmits image data of a rear end part in the primary scanning direction of each line in the line buffer to a boundary buffer. In the secondary scanning direction, a second block is adjacent to a first block, and a fourth block is adjacent to a third block. The third block is adjacent to the first block in the primary scanning direction. The filter execution circuit continuously performs filter execution of: (a) the rear end part in the primary scanning direction of (a1) the rear end part in the secondary scanning direction of the first block and (a2) the second block, and (b) the rear end part in the secondary scanning direction of the third block and (c) the fourth block, using the image data stored in the boundary buffer and the line buffer.
