Image encoding apparatus. |
摘要 |
<p>An image encoding apparatus includes a smoothing circuit (11) for smoothing a binary image to be encoded, a binary-encoding circuit (12) for binary-encoding the image smoothed by the smoothing circuit, a sampling circuit (13) for sub-sampling the image binary-encoded by the binary-encoding circuit, and an encoding circuit (26) for encoding the binary image sub-sampled by the sampling circuit. A degree of smoothness (G) of an image by the smoothing circuit and a threshold value (T1) for a binary-encoding operation of the binary-encoding circuit can be varied.</p> |
