A laser processing apparatus disclosed in the present application includes: an optical deflection unit capable of changing a deflection direction of and outgoing energy of an incoming laser pulse by changes of a frequency of and an amplitude of a driving signal to be supplied; and a control unit configured to supply driving signals with amplitudes corresponding to respective frequencies. In a laser processing apparatus configured to process a workpiece by leading outgoing laser pulse of the optical deflection unit to the workpiece and irradiating the workpiece with the laser pulse, as the amplitude corresponding to each of the frequencies, the control unit supplies an amplitude having the ratio that is close to the lowest ratio among ratios of the outgoing energy with respect to the incoming energy of the laser pulse at an amplitude having the largest outgoing energy of the optical deflection unit.

In a reference signal comparison AD conversion scheme, a reference signal SLP_ADC and each of P and D phases of a pixel signal voltage Vx are compared. A count clock CKcntis counted based on the comparison result. The counting result data is converted into signal data Dsig, i.e., the difference between the P and D phases, which is also subjected to CDS. At this time, the n-bit AD conversion is performed on each of the P and D phases of the pixel signal voltage Vx, followed by summation for digital integration. This prevents any possible detrimental effects that may be caused by summation in the analog domain. Although the signal data becomes W times greater, noise will likely become &#x221a;W times greater. This alleviates the problem of random noise resulting from AD conversion such as quantizing noise and circuit noise that do not exist in the analog domain, thus reducing the noise.
