DeCamera

A "kawaii" iOS selfie app that detects faces and makes the eyes larger — turning ordinary photos into wide-eyed, doll-like portraits.

Features

• Eye detection — uses Core Image CIDetector (CIDetectorTypeFace, high accuracy) to locate faces and per-eye positions, skipping eyes that are detected as closed.
• Eye-enlargement effects — applies a partial-region zoom or a fish-eye (spherical) warp around each detected eye, then blends the result back with an alpha mask for a seamless edge.
• Effect menu — selectable presets shown in a collection view, each with a hand-drawn Bézier-path eye icon:
  • do nothing — original image, no effect
  • clearly — sharpen / high-contrast eyes at 1.0x
  • big / bigger / biggest — natural-eye enlargement at 1.20x / 1.35x / 1.50x
  • bright — fish-eye spherical enlargement for a "brilliant", sparkly look
• Image input — capture from the camera (SACameraPickerViewController) or pick from the photo library (UIImagePickerController), with iPad-specific fallback via the AssetsLibrary reference URL.
• In-app purchase — a "BasicPack" unlocks the stronger effects (bigger, biggest, bright); locked items render a FontAwesome lock glyph. Purchase and restore are handled through CargoBay, with the purchase flag stored via SecureNSUserDefaults.
• Sharing — share processed images to Twitter, Facebook, and LINE via custom UIActivity subclasses, with a localized promo caption.
• Localization — English and Japanese (en.lproj, ja.lproj).
• Marketing / analytics — rating prompts (iRate), tell-a-friend (iTellAFriend), and Google Analytics event tracking.

Usage

This is a CocoaPods project that opens through an Xcode workspace, not the bare project file.

# Install dependencies (Pods/ is gitignored and not committed)
pod install

# Open the workspace — NOT DeCamera.xcodeproj
open DeCamera.xcworkspace

Then build and run the DeCamera scheme onto a physical iOS device (iOS 8.1+).

Notes:

• A physical device is required — the camera capture path logs a warning and no-ops on the Simulator, and face detection needs a real photo.
• The dependency versions pinned in Podfile / Podfile.lock are from circa 2014–2017; resolving them against today's CocoaPods spec repo and a modern Xcode/iOS SDK will likely require updates.
