Abstract: A front end signal processing method and apparatus for processing a signal from an image sensor are provided for readily clamping a black level, improving the manufacturing yield, and reducing the power consumption. A luminance detector/digitizer receives a sensor output signal from an image sensor, detects luminance information included in the sensor output signal, and generates a digital luminance signal representative of the detected luminance information.

Abstract: A method is provided for improving the performance of a circuit containing a three-terminal device. In the operation of a circuit containing three-terminal device 10, the influence of the Early effect pertaining to the three-terminal device of a FET is reduced. In order to reduce the influence, control unit 30 is set for reducing the Early effect component caused by a three-terminal device. As a result, by controlling the potential of the second terminal (such as drain) of the device as a response to a first signal pertaining to the input signal received by the first terminal (such as gate) of the device, it is possible for the potential difference between the second terminal (drain) and the third terminal (such as source) of the device to be essentially constant.

Abstract: A differential RS latch circuit has a series structure wherein a first differential transistor pair, a second differential transistor pair and a third differential transistor pair are connected in three stages, and jointly function as one current switch. A first diode serving as a first level shift element is provided in a first current path between a power source node and a grounding node, and second and third diodes serving as second and third level shift elements are provided in a second current path between the power source node and the grounding node. The number of elements provided in the first current path is equal to that of elements provided in the second current path. As a result, the first and second current paths are equal to each other in response speed to a signal, and thus an hazard is prevented from occurring even at the time of the switching operation between the first and second current paths.

A level-converting resistor for converting an ECL-level signal to a positive level signal is inserted between the first output node and the second output node so as to output the positive level signal in accordance with an ECL-level input signal to the first output node. The emitter-collector path of a bipolar transistor is inserted between the second output node and the positive power source voltage. A clamp potential for controlling saturation of transistors constituting a TTL circuit connected to an output of the transistor is generated by a constant potential applied to the base of the transistor.
