发明名称 Image information transmitting system.
摘要 <p>In an image information transmitting system of this invention, an image information signal constituted by a plurality of data constituting one frame is input. A plurality of pixel data blocks each consisting of a predetermined number of pixel data are formed from the input image information signal. Dynamic range information data associated with dynamic ranges of values of the pixel data constituting each pixel data block are formed in units of the plurality of pixel blocks. The pixel data constituting the pixel data block is coded using the dynamic range information data to form a plurality of coded data in units of pixel data blocks. The dynamic range information data and the coded data are sent onto a transmission line. These transmitted data are received, and a data portion of the dynamic range information data and the coded data which has an error is interpolated. High-quality image information can be efficiently transmitted.</p>
