Description

上記の投写表示システムにおいて、
前記抽出拡大部は、前記部分画像のデータサイズが前記原画像のデータサイズとほぼ等しくなるように、前記部分画像のデータサイズを拡大するようにしてもよい。 In the above projection display system,
Before Symbol extractor enlargements, so that the data size of the partial image is approximately equal to the data size of the original image may be expanded data size of the partial image.

上記の投写表示システムにおいて、
前記表示画像生成部は、さらに、
前記台数情報と前記識別情報とに応じた前記部分画像の抽出範囲と拡大倍率とを示すテーブルを備え、
前記抽出拡大部は、前記テーブルから得られる前記抽出範囲と前記拡大倍率とに従って、前記抽出処理および前記拡大処理を実行することが好ましい。 In the above projection display system,
The display image generation unit further includes
Includes a tables indicating the extraction ranges and magnification before Symbol partial image response Ji were in to the number information and the identification information,
It is preferable that the extraction enlargement unit executes the extraction process and the enlargement process according to the extraction range and the enlargement magnification obtained from the table.

このように、テーブルを用いれば、台数情報と識別情報とに応じて、部分画像の抽出範囲と拡大倍率とを容易に決定することができる。
特定の前記台数情報と前記識別情報とに対応する前記抽出範囲と前記拡大倍率とは、予め準備された複数組の前記抽出範囲および前記拡大倍率の中からユーザによって選択可能であってもよい。 As described above, if the table is used, it is possible to easily determine the extraction range and the enlargement magnification of the partial image according to the number information and the identification information .
The extraction range and the enlargement factor corresponding to the specific number information and the identification information may be selectable by a user from a plurality of extraction ranges and enlargement factors prepared in advance.
