US06922490B2 Image compression of selected regions based on transmission bit rate, motion, and/or region information, and bit selection before compression based on transmission bit rate 失效
基于传输比特率，运动和/或区域信息的所选区域的图像压缩，以及基于传输比特率的压缩之前的比特选择

Image compression of selected regions based on transmission bit rate, motion, and/or region information, and bit selection before compression based on transmission bit rate
摘要：
An image encoding device is provided that can transmit encoded image data without lowering the frame rate even when the transmission speed of the transmission path is lowered. An encoded region designator selects the region that is to be encoded, in the input image, depending on the bit rate of the transmission path. Only such a region that is designated by the encoded region designator is encoded. The encoded region designator may be one which selects the region that is to be encoded, according to the bit rate of the transmission path, and the motion vector detected by the image encoding circuit. As an alternative, an encoded region designator may be used which selects the region that is to be encoded according to the bit rate of the transmission path, and the information on the designated region supplied from the outside. Also, a selector limiting the number of bits of the signal from the image signal input circuit may be provided, and when the bit rate of the transmission path is lowered, the number of bits of the input image may be adaptively switched.

提供了即使当传输路径的传输速度降低时也可以传输编码图像数据而不降低帧速率的图像编码装置。 编码区域指示符根据传输路径的比特率在输入图像中选择要被编码的区域。 只有由编码区域指示符指定的这样的区域被编码。 编码区域指示符可以是根据传输路径的比特率和由图像编码电路检测到的运动矢量来选择要被编码的区域的区域。 作为替代，可以使用编码区域指示符，其根据传输路径的比特率以及从外部提供的指定区域上的信息来选择要被编码的区域。 此外，可以提供限制来自图像信号输入电路的信号的位数的选择器，并且当传输路径的比特率降低时，可以自适应地切换输入图像的比特数。
