Publication number: 20120327294Abstract: An apparatus, and an associated method, for a device containing a camera module. An ambient light sensor senses ambient light conditions and provides an indication of the sensed conditions to an exposure setter. The exposure setter utilizes the indication of the ambient light conditions in the selection of the initial exposure. Convergence procedures are utilized to converge the exposure settings to a final exposure setting.Type: ApplicationFiled: June 15, 2012Publication date: December 27, 2012Applicant: RESEARCH IN MOTION LIMITEDInventors: Gael Jaffrain, Gang Xue, Hong Yu Zhou

Publication number: 20120281106Abstract: An apparatus, and an associated method, for facilitating stabilization of a recorded video sequence, formed of captured image frames. Captured image frames are cropped by a frame cropper. Cropping of an image is dependent upon lighting conditions. Upon the occurrence of a low-light, lighting condition, the amount of cropping is altered. And, when acceptable lighting conditions return, the amount of cropping is again altered, all in a manner to facilitate video stabilization.Type: ApplicationFiled: March 5, 2012Publication date: November 8, 2012Applicant: RESEARCH IN MOTION LIMITEDInventors: Brett Stuart Foster, Bryan Andrew Krawetz, Mark David Rushby, Gael Jaffrain, Sung Ho Hong, Joshua Lucien Daigle, Gang Xue

Publication number: 20120268624Abstract: An apparatus, and an associated method, facilitates capturing an image in an electronic camera without having to wait for an image to settle or the camera to stabilize. Image frames are captured continuously. Data representing captured images is compressed. The compressed files are stored continuously, such that even before a shutter button is actuated, one or compressed image frames have already been recorded. When the shutter button is actuated, the largest of the compressed data files is selected for use, such as display, printing or transmission. Selection is made based on the size of the compressed image file.Type: ApplicationFiled: April 22, 2011Publication date: October 25, 2012Applicant: RESEARCH IN MOTION LIMITEDInventors: Dmitry Denisenkov, Gang Xue, Sung Ho Hong, Qian Wang

Publication number: 20110195578Abstract: A method and manufacture for charge storage layer separation is provided. A layer, such as a polymer layer, is deposited on top of an ONO layer so that the polymer layer is planarized, or approximately planarized. The ONO includes at least a first region and a second region, where the first region is higher than the second region. For example, the first region may be the portion of the ONO that is over the source/drain region, and the second region may be the portion of the ONO that is over the shallow trench. Etching is performed on the polymer layer to expose the first region of the ONO layer, leaving the second region of the ONO unexposed. The etching continues to occur to etch the exposed ONO at the first region so that the ONO layer is etched away in the first region and the second region remains unexposed.Type: ApplicationFiled: February 10, 2010Publication date: August 11, 2011Applicant: SPANSION LLCInventors: Angela T.

Publication number: 20100133646Abstract: A method for fabricating a memory device with U-shaped trap layers over rounded active region corners is disclosed. In the present invention, an STI process is performed before the charge-trapping layer is formed. Immediately after the STI process, the sharp corners of the active regions are exposed, making them available for rounding. Rounding the corners improves the performance characteristics of the memory device. Subsequent to the rounding process, a bottom oxide layer, nitride layer, and sacrificial top oxide layer are formed. An organic bottom antireflective coating applied to the charge trapping layer is planarized. Now the organic bottom antireflective coating, sacrificial top oxide layer, and nitride layer are etched, without etching the sacrificial top oxide layer and nitride layer over the active regions. After the etching the charge trapping layer has a cross-sectional U-shape appearance.Type: ApplicationFiled: February 3, 2010Publication date: June 3, 2010Inventors: Shenqing FANG, Angela HUI, Shao-Yu TING, Inkuk KANG, Gang XUE
