Abstract: An AD-converted digital video data is encoded by a difference encoding method before it is outputted and such encoded digital video data is then outputted, after it is converted to gray code or to a predetermined code in which a fixed value is added. Problems solved include noise that is generated when the AD conversion circuit outputs video data and that migrates into a CCD side via a power supply line on a printed circuit board, and noise that appears on a display image by migration into an input terminal side from an output circuit side via the power supply line and a semiconductor substrate within an AD conversion LSI.

Abstract: Using a plurality of relatively narrowband light sensors having overlapping response characteristics, accurate and self-calibrating colour measurements may be carried out. With sufficient measurements, simultaneous equations may be solved to derive a light intensity measurement at portions of the spectrum at which the overlapping sensor responses intercept. Using LEDs as light sensors provides cheap narrowband sensors and provides the additional advantage that the LEDs may also be used to illuminate a source to provide additional cross-reference measurements. Using sensors and/or illumination sources directed at several angles may also be used to improve sensing accuracy by mitigating the effects of surface texture and/or fluorescence.

Abstract: When a current mirror circuit is composed of transistors that inevitably form a parasitic photodiode between an epitaxial layer and a substrate layer because of structure of an integrated circuit, a photocurrent increases in proportional to an area of the epitaxial layer. Thus, the area of the epitaxial layer is adjusted in accordance with a current ratio of the current mirror, so as to allow the photocurrent to affect equally on both input and output sides of the current mirror circuit, i.e., so as to cancel the photocurrent. With this, in a current mirror circuit provided in an integrated circuit, it is possible to eliminate the influence of the photocurrent, without considerably increasing an element area or taking special measures to shield light.

Abstract translation: 当由于集成电路的结构，电流镜电路由不可避免地在外延层和衬底层之间形成寄生光电二极管的晶体管组成时，光电流与外延层的面积成比例地增加。 因此，根据电流镜的电流比来调整外延层的面积，以便允许光电流在电流镜电路的输入和输出侧均等地影响，即抵消光电流 。 由此，在集成电路中提供的电流镜电路中，可以消除光电流的影响，而不会显着增加元件面积或者采取特别的措施来屏蔽光。

Abstract: A charge generated in response to the quantity of the incident light into the photodiodes PD is accumulated in an integrating capacitor of an integrating circuit 10, and a voltage V10 in response to the quantity of the accumulated charge is outputted. The voltage V10 is inputted into a comparison circuit 20 and is compared with a prescribed threshold voltage therein. When the inputted voltage reaches the threshold voltage, a saturation signal F1 showing the same is outputted. A certain quantity of charge whose polarity is inverse to that of the charge accumulated in the integrating capacitor of the integrating circuit 10 is injected into the integrating n capacitor by the charge injecting circuit 30 on the basis of the saturation signal. The number of times of the voltage V10, which is outputted from the integrating circuit 10, reaching the threshold voltage is counted by the counting circuit 40 on the basis of the saturation signal outputted from the comparison circuit 20, wherein a quantity of incident light is detected on the basis of the counted made by the counting circuit 40 and the output voltage value from the integrating circuit 10.
