Abstract

An image transmitting system which maintains the same image resolution even when a line speed is set to a low speed. The image transmitting system basically comprises an image data conversion block, a quantization block, a variable-length coding block, smoothing buffers, output selectors, and a dequantization block. The image data conversion block converts input image data into a coefficient suitable for coding. The quantization block quantizes the coefficients obtained through conversion. The variable-length coding block codes the quantized coefficients. The first smoothing buffer smoothes the generated amount of data with respect to a first frame in a block, the second smoothing buffer smoothes the generated amount of data with respect to a second frame in the block, and the third smoothing buffer smoothes the generated amount of data with respect to a third frame in the block. The first output selector is used when selecting a line speed of 96 Kbps, and the second output selector is used when selecting a line speed of 128 Kbps. The quantization block reproduces the previous frame for use in an interframe conversion.
