摘要： An image processing apparatus includes a first and second Z value calculators that calculate a polygon Z value and a block Z value, respectively. The polygon Z value is a coordinate value of a pixel located at a closest point to a viewpoint. The block Z value is a coordinate value of a pixel located at a closest point to the viewpoint in a block. The apparatus also includes a Z value selector that selects a Z value of a pixel closer to the viewpoint from the polygon Z value and the block Z value as an estimate Z value; and a hidden-surface removal unit that eliminates drawing of the polygon in the block when a pixel corresponding to the estimate Z value is located at a farther point from the viewpoint than a pixel located at a farthest point from the viewpoint.

For example, the optical communication device includes: a pre-amplifier circuit PREAMP1 amplifying a current signal Iin from a photodiode PD, and converting an amplified signal into a voltage signal; and an operating-point controller circuit VTCTL1 controlling an operation of the PREAMP1. The PREAMP1 includes a negative feedback path formed by a feedback resistance Rf1, and includes: a level-shift circuit LS1 level-shifting in accordance with an operating-point control signal Vcon; and an amplifier circuit AMP1 connected to a subsequent stage of the LS1 and performing an amplifying operation with a high gain. The VTCTL1 includes a replica circuit configured by the same circuit and circuit parameter as those of the AMP1 and electrically connected between the input and the output, and generates the Vcon so that an output DC level of this replica circuit is matched with an input DC level of the AMP1.

The amplifier circuit block includes an analog adder for subtracting an output signal of the compensation circuit block from an input signal and an amplifier circuit operating in a wide band. The compensation circuit block includes an amplifier circuit with a low offset voltage and a low noise in a low frequency region, an analog adder block for subtracting an output signal of the amplifier circuit from an output signal of the amplifier circuit and generating a differential signal thereof, and a feedback circuit block for negatively feeding back the differential signal to the analog adder. The amplifier circuit block can reduce the offset voltage and the low-band noise by the negative feedback of the differential signal, and at the same time, the operation band of the entire amplifier circuit can be decided by the characteristic of the amplifier circuit.
