PURPOSE:To select and watch an image favorite in picture quality at a preception side by controlling directly an encoding parameter related to an amplitude resolution, a spatial resolution, etc., with a request by the reception side that watches a sent image. CONSTITUTION:A favorite picture quality is instructed to a transmission equip ment from an image transmission equipments 10a or 10b at the reception side with picture quality instruction knobs 13a and 13b. In other words, an output according to the picture quality instructing knobs 13a and 13b rotated to the left or to the right is sent to an opposite side, and the equipment at the opposite side controls the encoding parameter according to the parameter. For example, when the picture quality instruction knobs 13a and 13b are turned in a left- handed direction, the encoding parameter is handled as an automatic control mode, and the automatic adjustment of the resolution is performed. On the other hand, when it is turned in a right-handed direction, a state is controlled so as to put the amplitude resolution and the spatial resolution at the minimum level, and a time base resolution becomes maximum relatively and the encoding of the image faithful to a motion can be performed. |
