This application enables you to use your iPhone as a scanner. Works not only with documents, receipts, business cards, notebooks, catalogs and other paper-based media, but also with the likes of whiteboards, posters, and train schedules. Use this application to obtain high-quality images.

Upon importing images contained in your iPhones Photo Album or those taken with your devices camera, this application automatically recognizes the frame (outline) in the pictures, renders them so that they appear to be viewed from the front, and even enhances their attractiveness through applying color correction. This enables a level of image quality reminiscent of something taken with a scanner.

【Features】

The following represent a sample of the features offered by this application.

(1) Frame recognition (Detection of rectangular fields)
This application goes beyond simply recognizing four corner points and simultaneously detects the degree of distortion (the barrel distortion unique to cameras). Additionally, the application captures multiple candidate frames, thereby offering enhanced work efficiency relative to cases in which only one frame can be obtained.

(2) Front-facing adjustment
Photos taken at a diagonal are adjusted to make them appear to have been taken from the front. Distortion correction can also be carried out using the degree of distortion obtained through the frame recognition feature mentioned in (1) above.

(3) Color correction
This feature enables fine images to be taken in color as well as in black-and-white. Images are processed to ensure that even small characters are vividly reproduced. Furthermore, should shadows be present in the background of a photo, the application uses a background color modification function to eliminate only the shadows while preserving any characters or graphics.

気にいっています

会議でつかった板書を紙でプリントアウトして、PDFにしていました。 このソフトなら、写真をとっておけばiPhoneで自動補正してPDFにしておいてくれ、たいへん重宝してます。 iPhoneからメールで、送信するために、PDFの画質や、ホワイトバランスを調整して、つかっています。

スキャン性能は素晴らしいが、詰めが甘い

読み取り結果は、これまで使ってきたスキャナアプリでは一番綺麗です。 特に、モノクロの線がモードや歪曲補正、影の除去は素晴らしいです。 反面、他の方々も書かれていますが、保存時に他アプリで普通に出来ることが出来ないのは、かなりストレスを感じ、詰めの甘さを感じます。 evernoteは、複数枚のまとめて送信が出来ず、送信後にひとつひとつタイトルの修正やタグの設定をおこなう手間は、本当に面倒です。 連続で取り込みたい場合は向きません。 この手間を惜しむために、「カメラロールに一時保存▶メールで送信▶カメラロールの写真を削除」と言う手順を踏んています。 あと、お気に入りのスキャン設定をプリセット出来ません。 カラーの書類から、モノクロで名刺を取り込む設定に移るときには、複数の項目を設定し直さなければなりません。 3つ程で良いので、お気に入りの設定をプリセット出来ると、使い勝手が格段に向上すると思います。 とは言え、スキャンの早さ確実性、美しさは満足なので、今後のアップデートを期待してます。

素晴らしい

色々なアプリを試してみましたがこのアプリがダントツに綺麗 拡大しても細部まで字が潰れることもありません。 他のアプリではPDFにしか保存出来ないアプリも多いですがこのアプリはPDF・JEPGでも保存できちゃうのが気に入りました。 文句なし星5つにさせて頂きました!

オススメ

安いうちに買いましょう。某¥600のスキャナよりキレイにできます。

残念

安いだけに買いましたが、使える範囲はあんまりに狭く感じられます。雑誌も、パソコンのスクリーンも、ホワイトボードもろくに移せない。ただ新聞の画質がまあまあです。

トリミングについて

必要な部分まで撮られてしまうことが多いです。 他のレビューを見て、こんな評価がないようです。撮り方が悪いですか?
