摘要： In the television broadcasting system called letter box method, it is proposed to transmit an image having a larger aspect ratio than that of the existing broadcasting system by using some of the scanning lines of the existing broadcasting system, and transmit some additional information signal in the remaining portion. An offset value applied to the additional information signal at the transmission side must be removed completely at the reception side. Accordingly, at the reception side, in the scanning line in which an offset reference signal indicative of the offset value is transmitted, the offset reference value and a DC level reference value of the scanning line are detected, and these values are retained until a next offset reference signal is detected. By detecting a DC level of a scanning line containing the additional information signal, a difference from the DC level reference value previously detected and retained is obtained, and the offset reference value detected and retained previously is corrected by this difference. Thus obtained offset value is subtracted from the transmitted additional information signal.

摘要： In order to reduce a circuit scale such as a brightness adjustment circuit or the number of pins in an IC chip, in the brightness adjustment circuit, a brightness adjusted video signal (internal video signal) output from an analog signal synthesis circuit or a D/A converter is input to one input terminal of a switch and a sample/hold circuit. The sample/hold circuit holds a voltage of a level in accordance with the pedestal level of the internal video signal at a timing in accordance with a sampling pulse in synchronization with the internal video signal. A clamp circuit clamps the pedestal level of an external video signal in accordance with a clamp pulse, using the voltage held by the sample/hold circuit as the reference voltage, and input it to the other input terminal. The output terminal of the switch is connected to an amplifier.

摘要： 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. A digital processor receives the digital luminance signal, and multiplies the digital luminance signal by a predetermined gain code to generate the multiplication result as a front end processed signal output. An optical black clamp receives the digital luminance signal from the luminance signal detector/digitizer and supplies a feedback signal produced from the digital luminance signal to the luminance signal detector/digitizer to clamp a black level of the luminance signal to a constant value.

摘要： Defective pixels in a CMOS array give rise to spot noise that diminishes the integrity of the resulting image. Because CMOS arrays and digital logic can be fabricated on the same integrated circuit using the same processing technology and relatively inexpensive and fast circuit can be employed to digitally filter the pixel data stream and to identify pixels having values that do not fall in the range defined by the immediately neighboring pixels and the deviate from the neighboring pixels by more than a threshold amount. Such conditions would indicate that the deviation is caused by a defective pixel rather than by desired image data. The threshold amount can be preprogrammed or can be provided by a user or can be dynamically set using feedback indicating image quality. The filter would also provide a solution for other sensors such as CCD.
