Publication number: 20150130596Abstract: The present disclosure is directed to systems and methods in which a controllable device transfers to the remote device, such as to a remote control application (“app”) located on a smartphone, a data structure identifying various functions that can be controlled by a remote device, together with the identity of the signal type that will achieve the desired operation. The remote device, upon accepting input directly from the remote device, can then allow the remote device user to select how controls of the various functions are to be configured and presented to, or otherwise selectively arranged for a user on a user interface of the remote device. In this way, the present disclosure provides a single highly customizable system. Distributors, resellers, and/or manufacturers of various electronic devices will be able utilize the same controllable device instructions, yet visually distinguish its brand name from other solutions using the same instructions.Type: ApplicationFiled: January 20, 2015Publication date: May 14, 2015Applicant: Zoran CorporationInventors: Vladislav Aginsky, Dani Shaket

Publication number: 20120120197Abstract: A system, method, and computer program product for providing pseudo 3D user interface effects in a digital camera with existing lens distortion correction hardware. A distortion map normally used to correct captured images instead alters a displayed user interface object image to support production of a “pseudo 3D” version of the object image via production of at least one modified image. A blending map also selectively mixes the modified image with a second image to produce a distorted blended image. A set or series of such images may be produced automatically or at user direction to generate static or animated effects in-camera without a graphics accelerator, resulting in hardware cost savings and extended battery life.Type: ApplicationFiled: May 11, 2011Publication date: May 17, 2012Applicant: ZORAN CORPORATIONInventors: Dmitry RYUMA, Daniel Fishkov, Erez Galil, Shimon Pertsel, Chang Liu

Publication number: 20120063282Abstract: Improved control of spindle speed during optical media seek operations is provided by adjusting the spindle motor speed during the actual optical pickup unit movement. In response to receiving a seek instruction to move an optical pickup unit to a target position, the current signal frequency corresponding to a current spindle motor speed may be determined. A target signal frequency corresponding to a desired spindle motor speed at the target position may also be computed. Thereafter, the current spindle motor speed may be adjusted towards the desired spindle motor speed prior to the optical pickup unit reaching the target position.Type: ApplicationFiled: June 1, 2009Publication date: March 15, 2012Applicant: ZORAN CORPORATIONInventors: Cong Cao, CaiZhi Zhu, BoWen Chen

Patent number: 8125536Abstract: An image capture system is presented where the dynamic range of photo imaging devices, such as a still or video camera, is increased by varying sensor exposure time on a pixel-by-pixel basis under digital camera processor control. The system's photo sensors are continuously illuminated without reset over the exposure interval. In addition to being interrogated at the end of the exposure interval, the pixels are also non-destructively interrogated at one or more intermediate times during the interval. At each interrogation, the image capture system determines individually whether the pixels have saturated and if not, the parameter value is recorded; if the pixel has saturated, the previously stored value from the preceding interval is maintained. To produce the final sensor value for the whole exposure interval, the data for pixels that reached the saturation level are adjusted to compensate for their shortened exposure.Type: GrantFiled: September 17, 2009Date of Patent: February 28, 2012Assignee: Zoran CorporationInventors: Shimon Pertsel, Ohad Meitav

Patent number: 8120669Abstract: A digital camera system in which capture, processing and storage functions are partitioned differently than in existing systems. A hand-held digital camera is used with a workstation that may exist in a commercial image processing service center. A minimal amount of image data processing is performed in the digital camera, thereby allowing significant digital camera cost reductions due to lower memory requirements, lower processing requirements, and lower power requirements. Real-time single pass image compression techniques are employed within this digital camera to permit rapid gathering and storage of raw or minimally processed image data. The workstation to which the image data are transferred performs the image processing normally done within existing cameras. This processing takes advantage of the increased computational power that is possible to have in such a workstation, compared to that of a small camera, and the increased time over which such processing may be performed.Type: GrantFiled: October 1, 2009Date of Patent: February 21, 2012Assignee: Zoran CorporationInventors: Ohad Meitav, Daniel Seltz, Itzhak Shenberg

Patent number: 8108749Abstract: An iterative decoder circuit includes an N number of sub-decoders, N?1 of the sub-decoders each being responsive to a baseband signal from one of M number of signal processing circuits. Each of the N?1 number of sub-decoders includes, an inner delay responsive to a baseband signal provided by a corresponding signal processing circuit for generating an inner delayed signal, a modified decoder that receives the inner delayed signal and generates a set partition signal, some of which have less errors than previous set partition signals. An Nth inner delay is responsive to the baseband signal and provides an Nth inner delayed signal. An Nth modified decoder is responsive to the Nth inner delayed signal and to the set partition signal and provides an output signal, wherein the probability of error of the output signal is reduced by correcting errors in some of the set partition signals.Type: GrantFiled: March 6, 2008Date of Patent: January 31, 2012Assignee: Zoran CorporationInventors: Jordan Christopher Cookman, Ping Dong, Tao Yu

Patent number: 8102444Abstract: Techniques for implementing a Black Level Correction (BLC) processing operation on image data signal pixel values that results in little to no nonlinearity in the dark areas of the image due to black noise clipping, and avoids reducing image quality or adding cost, are provided. Image data signal pixel values are caused to maintain black level while being operated on by image data signal processor circuits that precede a Noise Reduction (NR) processing operation, thus allowing the BLC processing operation to be executed after the NR processing operation. With black noise mostly removed, little to no nonlinearity in the dark areas of the image due to black noise clipping results from the BLC processing operation.Type: GrantFiled: September 4, 2009Date of Patent: January 24, 2012Assignee: Zoran CorporationInventors: David Vakrat, Noam Korem

Patent number: 8103806Abstract: A circuit capable of reading an input from a device on one pin of an integrated circuit package during one time period and either writing data to another device or reading an input from the other device through the same pin during another time period. In one exemplary implementation in which the one pin is used to write data to the other device, the circuit may sense when data is not being written and change the function of the one pin from that of an output pin to that of an input pin until such time as further data is to be written.Type: GrantFiled: May 23, 2008Date of Patent: January 24, 2012Assignee: Zoran CorporationInventors: Liron Ain-Kedem, Nir Leshem

Patent number: 8098304Abstract: Rather than storing a table within a digital camera or other optical device of defective pixels within its image sensor, defective pixels are dynamically identified by comparing the output values of individual pixels under test with those of neighboring pixels. If the neighbors are all above or below the pixel under test by a defined threshold amount, the output of the pixel under test is replaced with a value calculated from the outputs of neighboring pixels.Type: GrantFiled: February 26, 2008Date of Patent: January 17, 2012Assignee: Zoran CorporationInventors: Victor Pinto, Diana Shaposhnik
