  • Publication number: 20150130596
    Abstract: 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.

  • Publication number: 20120307266
    Abstract: A color printing method includes converting source color data to intermediate color data represented in a device independent color space using a first multidimensional gamut mapping of the first device dependent color space to the device independent color space. The device independent color space has a neutral color component. The method further includes converting the intermediate color data to destination color data represented in a second device dependent color space using a second multidimensional gamut mapping of the device independent color space to the second device dependent color space. The second device dependent color space has three primary color components and a virtual black color component defined by substantially equal tonal values of the three primary color components. The second multidimensional gamut mapping includes a mapping from the neutral color component of the device independent color space to the virtual black color component of the second device dependent color space.

  • Publication number: 20120120197
    Abstract: 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.

  • Publication number: 20120063282
    Abstract: 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.

  • Patent number: 8125536
    Abstract: 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.

  • Patent number: 8120669
    Abstract: 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.

  • Patent number: 8106972
    Abstract: A device for noise reduction is provided. The device includes a noise reduction three-dimensional look-up table (LUT) and a noise reduction unit. The noise reduction LUT transforms an input image into a noise reduction factor and noise reduction threshold for each color component of each pixel of the input image. The noise reduction unit performs noise reduction on the input image based on the noise reduction factors and noise reduction thresholds determined from the noise reduction LUT.

  • Patent number: 8108749
    Abstract: 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.

  • Patent number: 8102444
    Abstract: 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.

  • Patent number: 8098304
    Abstract: 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.
