Abstract

An image transmitting apparatus includes a region detecting unit detecting, in an image, a region of interest matching a predetermined condition; a resolution converting unit selecting, for reducing resolution of the image, an image passed through a low-pass filter as an image outside the detected region of interest and an image not passed through the low-pass filter as an image inside the region of interest; and a transmitting unit transmitting the image with reduced resolution and positional information of the region of interest. An image receiving apparatus includes a resolution restoring unit performing image quality improvement processing on the region of interest obtained from the positional information and included in the image transmitted from the image transmitting apparatus so as to increase resolution in the region of interest; and a combining unit combining the image inside the processed region of interest with the image outside the region of interest.

1 . An image transmitting apparatus comprising:
 region detecting means for detecting, in an image, a region of interest that matches a predetermined condition;   resolution converting means for selecting, for reducing resolution of the image, an image passed through a low-pass filter as an image outside the region of interest detected by the region detecting means and an image not passed through the low-pass filter as an image inside the region of interest; and   transmitting means for transmitting, to a destination, the image with resolution reduced by the resolution converting means and positional information of the region of interest.
