Publication number: 20130088624Abstract: A method of implementing high dynamic range bin algorithm in an image sensor including a pixel array with a first super row having a first integration time and a second super row having a second integration time is described. The method starts by reading out image data from the first super row into a counter. Image data from the first super row is multiplied by a factor to obtain multiplied data. The factor is a ratio between the first and the second integration times. The multiplied data is then compared with a predetermined data. The image data from the second super row is readout into the counter. If the multiplied data is larger than the predetermined data, the multiplied data from the first super row is stored in the counter. If not, the image data from the second super row is stored. Other embodiments are also described.Type: ApplicationFiled: February 3, 2012Publication date: April 11, 2013Applicant: OMNIVISION TECHNOLOGIES, INC.Inventors: Yaowu Mo, Chen Xu, Min Qu, Xiaodong Luo, Donghui Wu

Patent number: 8305474Abstract: An image sensor has a per-column ADC arrangement including first and second capacitors allowing a comparator circuit to perform correlated double sampling. The capacitors are continuously connected to, respectively, the analog pixel signal and a ramp signal without use of a hold operation. The comparator circuit comprises a differential input being connected to the junction of the two capacitors and being biased by a reference signal. The reference signal is preferably sampled and held from a reference voltage. The use of a differential input as first stage of the comparator addresses problems arising from ground voltage bounce when a large pixel array images a scene with low contrast. Connectivity of the differential input stage allows the ramp signal to see a constant capacitive load thus reduce image artifacts referred to as smear.Type: GrantFiled: November 19, 2009Date of Patent: November 6, 2012Assignees: STMicroelectronics (R&D) Ltd., STMicroelectronics SA (Morocco), STMicroelectronics (Grenoble 2) SASInventors: Matthew Purcell, Graeme Storm, Derek Tolmie, Mhamed El Hachimi, Laurent Simony, Min Qu

Publication number: 20090157741Abstract: The present invention provides a solution of transferring a data object between files through copy/paste, in which not only the filtered data object which is adapted to the format and/or function of a destination file is explicitly written to the destination file, but also the original data object information is implicitly written to the destination file, and the map relationship between them is established, so that the whole original information of the transferred data object is reserved during the transfer between files. In subsequent copy/paste operations, the user may choose to use the original data object corresponding to the data object in the transfer of the data object or not based on the actual situation and particular needs, so that the problem of information loss in the process of transferring a data object between files through copy/paste operation is solved effectively.Type: ApplicationFiled: December 11, 2008Publication date: June 18, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Yuan Cheng, Yue Ma, Min Qu, Hai F.
