    • A device for encoding a plurality of information signals using a joint computing power includes a plurality of encoders for encoding a respectively different one of the information signals using the joint computing power, wherein each encoder is controllable via at least one respective encoding parameter with regard to its encoding complexity/encoding distortion performance. A provider for providing, for each of the encoders, signal-dependent information dependent on the respective information signal and indicating an encoding distortion of the respective encoder, and a setter for setting the encoding parameters depending on the signal-dependent information considering the joint computing power such that a combination of encoding complexities of the encoders does not exceed a value dependent on the joint computing power are also provided, wherein the setter for setting and the plurality of encoders cooperates such that, with regard to subsequent time intervals, a distribution of the joint computing power depends on the encoding parameters or an encoding complexity of the individual encoders.

    • An image encoder includes an extreme value determiner, a floating point-to-integer converter and an encoder. The extreme value determiner determines minimal and maximal values of a floating point image value of each pixel of a part of an image, an image or a group of images. The floating point-to-integer converter maps the floating point image value of each pixel to an integer image value. The minimal floating point image value is mapped to a minimal integer image value of a predefined range of integer image values and the maximal floating point image value is mapped to a maximal integer image value of the predefined range of integer image values. The encoder encodes the integer image value of each pixel to obtain and provide encoded image data of the part of the image, the image or the group of images.
    • 图像编码器包括极值确定器,浮点到整数转换器和编码器。 极值确定器确定图像,图像或图像组的一部分的每个像素的浮点图像值的最小值和最大值。 浮点整数转换器将每个像素的浮点图像值映射到整数图像值。 将最小浮点图像值映射到整数图像值的预定义范围的最小整数图像值,并将最大浮点图像值映射到整数图像值的预定义范围的最大整数图像值。 编码器对每个像素的整数图像值进行编码,以获得并提供图像的一部分,图像或图像组的编码图像数据。
