摘要:
Digital image data obtained by A/D converting an output signal from an image sensing device by an A/D conversion circuit is converted into image data corresponding to a predetermined image format by a digital process of an image conversion circuit. Therefore, an image of higher quality without deterioration in the picture can be provided in comparison with the case where digital image data obtained by A/D converting an output signal from an image sensing device is first converted into analog video data and then into A/D data. Further format conversion can be performed using a series of controllable image converters. The image converters and a signal processing unit can be selectively programmed to perform a variety of format conversions and image-type specific signal processing, respectively. Programming can be performed manually or automatically according to the type of input device or the type of information in the image.
摘要:
A level shift element is connected between a transistor (Tr.sub.5) which is used to determine a threshold level when the input voltage falls and a diode (D.sub.3) is connected between an input terminal and an output control transistor (Tr.sub.2) to discharge the base of the output control transistor. The level shift element comprises a diode connected in the forward direction or a resistor.
摘要:
A structure and method for manufacturing semiconductor devices by the master slice method, in which various kinds of semiconductor devices are manufactured through utilization of a common master pattern and a plurality of different kinds of selective wiring patterns. A number of bipolar transistors each having plural emitter regions, is formed in a predetermined region, or portion, of a semiconductor substrate by employing a common master pattern, and the plural emitter regions of the respective bipolar transistors are selectively connected by the associated wiring patterns of each thereof to form corresponding bipolar transistors of different, predetermined D.C. characteristics. When manufacturing many different kinds of semiconductor devices by the master slice method, the area which would be wasted on the semiconductor substrate by prior art techniques is greatly reduced, thus providing for enhanced area efficiency.
摘要:
Electrostatical breakage of a semiconductor device, including an epitaxial layer and a buried layer thereunder, connected to an outer signal terminal, can be prevented by forming an impurity region in the epitaxial layer so as to form a PN junction between the buried layer and the impurity region. The impurity region is connected to a power source or ground.
