    Abstract: An image capture device that includes an adjustment circuit configured to monitor image parameters, generate updated image settings for the image capture device in response to the monitored image parameters, and transmit the updated image settings to one or more processors. The updated image settings configure the one or more processors to determine whether to transition the image capture device from a dynamic scene mode to a static scene mode based on a first image parameter included in the monitored image parameters, wherein the first image parameter is different from a second image parameter used to determine to transition the image capture device from the static scene mode to the dynamic scene mode, and to suspend generation of all or less than all of the updated image settings in response to determining to transition the image capture device from the dynamic scene mode to the static scene mode.

    Abstract: The disclosure describes a method for performing a fixed point calculation of a floating point operation (A // B) in a coding device, wherein A // B represents integer division of A divided by B rounded to a nearest integer. The method may comprise selecting an entry from a lookup table (LUT) having entries generated as an inverse function of an index B, wherein B defines a range of values that includes every DC scalar value and every quantization parameter associated with a coding standard, and calculating A // B for coding according to the coding standard based on values A, B1 and B2, wherein B1 and B2 comprise high and low portions of the selected entry of the LUT. The techniques may simplify digital signal processor (DSP) implementations of video coders, and are specifically useful for MPEG-4 coders and possibly others.

    Abstract translation: 本公开描述了一种用于在编码装置中执行浮点运算（A // B）的固定点计算的方法，其中A // B表示A除以被舍入为最接近整数的B的整数除法。 该方法可以包括从具有作为索引B的反函数生成的条目的查找表（LUT）中选择条目，其中B定义包括每个DC标量值和与编码标准相关联的每个量化参数的值的范围，以及 基于值A，B1和B2，根据编码标准计算A // B进行编码，其中B1和B2包括LUT的所选条目的高和低部分。 这些技术可以简化视频编码器的数字信号处理器（DSP）实现，并且对MPEG-4编码器和可能的其它编码器特别有用。

    Abstract: A method and apparatus for eighth-rate random number generation for speech coders includes a random number generator configured to generate values of a first random variable. The lookup table is used to store values of a second random variable. The lookup table is addressed with the values of the first random variable. The second random variable is an inverse transform of a cumulative distribution function of the first random variable. A codec encodes input silence frames with the values of the first and second random variables, and regenerates the silence frames with the values of the first and second random variables. The speech coder may be an enhanced variable rate coder, and the silence frames may be encoded at eighth rate. The random variables are advantageously Gaussian random variables with values that are uniformly distributed between zero and one.
