Image processing apparatus and image communicating apparatus

Claim 2

Image communicating apparatus for processing image data transmitted through a transmission line, the transmission rate of the image data being variable, comprising: receiving means for receiving the image data; discriminating means for discriminating the transmission rate of the image data received by said receiving means; display processing means for executing a process for displaying the image data received by said receiving means; and control means for changing a process of said display-processing means in accordance with the transmission rate discriminated by said discriminating means.

Claim 3

An apparatus according to claim 1, wherein said control means controls a display size of the received image data.

Claim 4

An apparatus according to claim 2, wherein when the transmission rate discriminated by said discriminating means is low, said control means sets the display size of the received image data to a value smaller than that in a case where the transmission rate is high.

Claim 5

An apparatus according to claim 1, wherein said control means changes smoothing characteristics of the received image data in accordance with the transmission rate discriminated by said discriminating means.

Claim 6

An apparatus according to claim 1, wherein the received image data is moving image data.

Claim 7

An apparatus according to claim 1, wherein the received image data comprises image data adapted to the H.261 standard.

Claim 8

An apparatus according to claim 1, further comprising: reproducing means for reproducing the received image data as a visible image.

Claim 9

Image communicating apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: receiving means for receiving the image data; discriminating means for discriminating the transmission rate of the image data received by said receiving means; image size discriminating means for discriminating an image size of an image corresponding to the image data received by said received means; and conversion means for converting a display size of the image corresponding to the received image data in response to an output of said discriminating means and an output of said image size discriminating means.

Claim 10

Image communicating apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: receiving means for receiving the image data; discriminating means for discriminating the transmission rate of the image data received by said receiving means; image size discriminating means for discriminating an image size of an image corresponding to the image data received by said received means; and conversion means for converting a display size of the image corresponding to the received image data in response to an output of said discriminating means and an output of said image size discriminating means.

Claim 11

An apparatus according to claim 8, further comprising: visible image display means for displaying the received image data as a visible image.

Claim 12

Apparatus according to claim 8, further comprising display means for displaying the image converted by said conversion means.

Claim 13

Image processing apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: receiving means for receiving the image data; discriminating means for discriminating the transmission rate of the image data received by said receiving means; smoothing means for smoothing the image data received by said receiving means; and control means for changing a smoothing process of said smoothing means in response to the transmission rate discriminated by said discriminating means.

Claim 14

Image processing apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: receiving means for receiving the image data; discriminating means for discriminating the transmission rate of the image data received by said receiving means; smoothing means for smoothing the image data received by said receiving means; and control means for changing a smoothing process of said smoothing means in response to the transmission rate discriminated by said discriminating means.

Claim 15

An apparatus according to claim 11, wherein the received image data is block encoded.

Claim 16

An apparatus according to claim 12, wherein said smoothing means executes the smoothing process so as to eliminate a block distortion which occurs due to the block encoding.

Claim 17

An apparatus according to claim 11, wherein the received image data is moving image data.

Claim 18

Apparatus according to claim 11, wherein, when the transmission rate discriminated by said discriminating means is lower than a predetermined value, said control means changes the smoothing process of said smoothing means to a smoothing process which is stronger than a smoothing process used when the transmission rate discriminated by said discriminating means is higher than the predetermined value.

Claim 19

Image processing apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: input means for inputting the image data; discriminating means for discriminating the transmission rate of the image data inputted by said input means; and conversion means for converting an aspect ratio of the inputted image data to a different aspect ratio in response to the transmission rate discriminated by said discriminating means.

Claim 20

Image processing apparatus for processing image data transmitted through a transmission line, a transmission rate of the image data being variable, comprising: input means for inputting the image data; discriminating means for discriminating the transmission rate of the image data inputted by said input means; and conversion means for converting an aspect ratio of the inputted image data to a different aspect ratio in response to the transmission rate discriminated by said discriminating means.

Claim 21

Apparatus according to claim 16, further comprising display means for displaying an image corresponding to the inputted image data converted by said conversion means.

Claim 22

Apparatus according to claim 16, wherein the input image data comprises block-encoded data.
