Patent number: 10458841Abstract: An embodiment of a method for compensating variations in an attenuation of light of an optical filter of a light sensor system comprises illuminating a clear sensor and a color sensor of the light sensor system with a test light having a test spectrum. Therein the color sensor comprises the optical filter and is designed to predominantly sense light with a wavelength within a pass band of the filter; and the test spectrum has components outside the pass band. A clear test signal generated by the clear sensor and a color test signal generated by the color sensor are received in particular in response to the illumination with the test light. Then a first transmission value T is determined based on the clear test signal and on the color test signal. Finally, a compensation factor Kr, Kg, Kb is calculated to compensate the variations in the attenuation of light based on the first transmission value T and a nominal transmission value Tn of the filter.Type: GrantFiled: November 30, 2015Date of Patent: October 29, 2019Assignee: ams AGInventors: Dan Jacobs, Eugene G.

Publication number: 20190109254Abstract: A sensor device comprises a semiconductor substrate with a first type of electrical conductivity and with a photodiode structure for detecting incident UV radiation. The photodiode structure comprises a first well arranged within the semiconductor substrate and having a second type of electrical conductivity and a second well arranged at least partially within the first well and having the first type of electrical conductivity. A doping concentration of the first well is greater than a doping concentration of the second well within a surface region at a main surface of the semiconductor substrate.

Patent number: 9683889Abstract: A photodiode (2) and a further photodiode (3) are arranged in a substrate (1) at or near a main surface (10). The photodiodes are formed and arranged in such a manner that in case of incident ultraviolet radiation (26) the electric signal from the photodiode (2) is larger than the further electric signal from the further photodiode (3). In particular, the first photodiode may be more sensitive to ultraviolet radiation than the further photodiode. The electric signal from the photodiode is attenuated by the further electric signal and thus yields an electric signal primarily measuring the incident ultraviolet radiation. The attenuation of the electric signal from the first photodiode may be achieved internally using an integrated circuit (25) or externally using a separate device.Type: GrantFiled: March 7, 2014Date of Patent: June 20, 2017Assignee: AMS AGInventors: Eugene G.

Patent number: 7286179Abstract: 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, although a single chip solution would likely not be possible.Type: GrantFiled: March 10, 2004Date of Patent: October 23, 2007Assignee: Texas Instruments IncorporatedInventors: Zhiliang Julian Chen, Eugene G.

Patent number: 6943721Abstract: An linear optical sensor charged-coupled topology using single-stage inverting charge-coupled amplifier driving an analog-to-digital converter which uses the converter full-scale reference as a precharge level. Since an offset in the range of 100–200 mV is introduced in the charge amplifier, a corresponding offset is also introduced into the ADC to allow the amplifier to more quickly drive the amplifier output to a low level. The converter offset is proportional to the converter reference to ensure that it is controlled and tracks the reference.Type: GrantFiled: June 15, 1999Date of Patent: September 13, 2005Assignee: Texas Instruments IncorporatedInventors: Cecil J. Aswell, Eugene G. Dierschke, John Hull Berlien Jr.

Patent number: 6788340Abstract: Image enhancement is automatically achieved by calibrating the reference voltage and gain of a differential amplifier and the integration interval so as to provide an input to a differential analog to digital converter (ADC) that utilizes the full dynamic range of the ADC. When used with a CMOS array, the imaging logic can be fabricated on a single chip with the array using combinational logic for fast, inexpensive calibration. Another advantageous feature is the ability to expand a desired portion of the luminance spectrum of the image in order to increase the digital resolution of the resulting image for that portion of the spectrum of interest.Type: GrantFiled: December 30, 1999Date of Patent: September 7, 2004Assignee: Texas Instruments IncorporatedInventors: Zhiliang Julian Chen, Eugene G.
