摘要:
A system for capturing a high dynamic range (HDR) image comprises an image sensor comprising a split pixel including a first pixel having higher effective gain and a second pixel having lower effective gain. The second pixels exposed with a capture window capture at least a pulse emitted by a light emitting diode (LED) controlled by a pulse width modulation. A first HDR image is produced by a combination including an image produced by the second pixels, and images produced by multiple exposures of the first pixels. A weight map of LED flicker correction is generated from the difference of the image produced by second pixels and the images produced by the first pixels, and the flicker areas in the first HDR image are corrected with the weight map and the image from the second pixels.

A voltage control circuit includes a processing unit, a power control circuit, a first impedance circuit, a first switch, and a current source. The power control circuit is used for outputting a core voltage to the processing unit. The first switch and the first impedance circuit are connected in parallel between the processing unit and the power control circuit, and they feedback a feedback voltage to the power control circuit. The current source is used for providing or extracting an operating current via the first impedance circuit or the first switch. The first switch is turned on and the processing unit receives a first core voltage when the processing unit operates at a normal mode. The first switch is turned off and the processing unit receives a second core voltage when the processing unit operates at an overvoltage mode.

There are provided video encoders and corresponding methods for encoding video data for an image that is divisible into macroblocks. A video encoder includes an encoder for performing into mode selection when encoding a current macroblock by testing a first subset of intra modes to compute a rate distortion cost, and utilizing the rate distortion cost to determine whether to terminate the intra mode selection and which additional intra modes, if any, are to be examined with respect to the current macroblock.

High dynamic range image sensors and image reconstruction methods for capturing high dynamic range images. An image sensor that captures high dynamic range images may include an array of pixels having two sets of pixels, each of which is used to capture an image of a scene. The two sets of pixels may be interleaved together. As an example, the first and second sets of pixels may be formed in odd-row pairs and even-row pairs of the array, respectively. The first set of pixels may use a longer exposure time than the second set of pixels. The exposures of the two sets of pixels may at least partially overlap in time. Image processing circuitry in the image sensors or an associated electronic device may de-interlace the two images and may combine the de-interlaced images to form a high dynamic range image.

摘要:
An imager includes an array of pixels arranged in rows and a control circuit for sequentially capturing first and second image frames from the array of pixels. The control circuit is configured to sequentially capture first and second pairs of adjacent rows of pixels during first and second exposure times, respectively, when capturing the first image frame. The control circuit is also configured to sequentially capture first and second pairs of adjacent rows of pixels during second and first exposure times, respectively, when capturing the second image frame. The first exposure times during the first and second frames are of similar duration; and the second exposure times during the first and second frames are of similar duration. The control circuit is configured to detect motion of an object upon combining the first and second image frames and, then, correct for the motion of the object.
