A photographing guide device includes a detection means and an output means. The detection means compares a candidate image of a structure captured from a capturing candidate position in a capturing candidate direction with a registered image of the structure captured from a given capturing position in a given capturing direction and stored in advance, thereby detecting a positional difference between the capturing candidate position and the given capturing position. The output means outputs information indicating the detected positional difference.

Provided is an image encoding apparatus capable of encoding a region important to a user with high quality. An update interval index calculation unit calculates an update interval index representing an index having a long update interval in an entire update tile overlapping the update region for each update region. An importance region specification unit specifies an important region, from each update region by using the update interval index. An quality control unit allocates a code amount, which is larger than a result obtained by dividing the total target code amount per one frame proportionally according to a ratio of an area of an entire important region with respect to an area of an entire update region, as a target code amount of the entire important region and specifies a quality value of the entire important region on the basis of the target code amount.

A removal region detection means detects a rectangular non-update region from a circumscribed rectangle of all update blocks. An update region dividing means divides the circumscribed rectangle of all update blocks into two or more rectangular update regions not including the detected non-update region. If the number of update regions after the division does not exceeds a threshold, a division processing control means recursively applies the processing by the removal region detection means on the update regions after the division, and recursively applies the processing by the update region dividing means based on the detected non-update region. The division processing control means terminates repetition of the division processing of the update region on a condition that a new non-update region is not detected any more by the removal region detection means, or that the number of update regions exceeds the threshold, whichever is satisfied earlier.

A retransmission candidate tile extracting unit extracts from within a screen a tile which does not belong to an updated region in a current frame and which is a partial region transmitted after encoded with a quality equal to or less than a first quality. A character likelihood estimating unit, with respect to a tile extracted by the retransmission candidate tile extracting unit, calculates a likelihood value indicating likelihood that the tile is a character region. A character-likelihood-order intra update unit selects a tile in decreasing order of the likelihood value from among tiles extracted by the retransmission candidate tile extracting unit, and encodes the tile with a second quality which is higher than the first quality and transmits the result.
