  • Publication number: 20110268318
    Abstract: A photo detecting apparatus may include a signal processing unit, a control register unit, and a register data changing unit. The signal processing unit is configured to process electric signals converted from incident light to generate image data. The control register unit supplies a set value to the signal processing unit, the set value controlling operation of the signal processing unit. The control register unit stores a first set value supplied through a first bus, the first set value corresponding to an initial set value based on a decoded external control signal. In addition, the register data changing unit supplies a second set value to the control register unit through a second bus, separate from the first bus, when the first set value is to be changed.
