It saves still images from the built-in iSight or other video devices, making webcam snapshots scriptable from the terminal. ### プロジェクトの歴史 Robert Harder's older iHarder Mac OS X utilities page describes ImageSnap as a successor path after Axel Bauer's `isightcapture`, with the goal of adapting command-line camera capture to Apple's changing architectures. The GitHub README identifies Robert Harder as the original author and documents the tool as public-domain software. The project lived for years as an Objective-C utility, then gained a Swift rewrite using AVFoundation in the 0.3.0 series. The README notes that the Swift rewrite modernized the media stack but raised the macOS requirement to Ventura-era systems, while older Objective-C versions remain available from tags and releases. ### 採用の歴史 ImageSnap became a small but recognizable Mac package-manager tool because it does one thing Unix users expect to script: take a camera snapshot without opening a full camera app. The README names Homebrew and MacPorts as common installation paths, and Homebrew analytics show a steady low-thousands yearly install base. Its package adoption is tied to automation scenarios such as quick webcam captures, simple time-lapse scripts, hardware checks, and headless-ish Mac workflows where AVFoundation access can still be granted through macOS camera permissions. ### 使われ方 The `imagesnap` command captures to `snapshot.jpg` by default, accepts a filename as the final argument, lists cameras with `-l`, selects a device with `-d`, and supports time-lapse captures with `-t` and `-n`. It can write common formats such as JPEG, TIFF, PNG, GIF, and BMP based on the output filename extension. The README documents a warmup delay, because real cameras need time after activation before a frame is useful. The tool also has to participate in macOS camera permission prompts the first time it is used. ### パッケージ好きにとっての重要性 ImageSnap is package-nerd useful because it exposes an Apple media-framework feature as a tiny, scriptable binary. It is the kind of package people install once for a build lab, kiosk, CI-adjacent hardware check, or personal automation and then forget until they need a camera frame from a shell script. ### タイムライン - 2010s: iHarder described ImageSnap as a way forward from the older `isightcapture` utility. - 2017: Version 0.2.6 appeared in GitHub releases. - 2021: The 0.2.x series continued with camera-capture maintenance releases. - 2023: Version 0.2.16 was released before the Swift rewrite line. - 2026: Version 0.3.0 introduced a Swift rewrite using AVFoundation. ### Related projects - The historical comparison is Axel Bauer's `isightcapture`, which ImageSnap's original project page explicitly mentions. Within package managers, Homebrew and MacPorts both carry ImageSnap for macOS camera capture. ### ソース - - - - - ## セキュリティノート broad file, network, media, or database tool signal. - **Geiger リスク:** blue / 中 - broad file, network, media, or database tool signal ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** imagesnap - **Version Scheme:** 0 - **Revision:** 0 - **Requirements:** macos, xcode - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - MacPorts - ImageSnap: normalized package name match | MacPorts ports tree: sysutils/ImageSnap/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 関連リンク - [Source-control packages](https://www.automicvault.com/ja/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/ja/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/ja/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/ja/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [aravis](https://www.automicvault.com/ja/pkg/brew/aravis/) - Shares av.db curated category or tags: camera, cli, media. - [folderify](https://www.automicvault.com/ja/pkg/brew/folderify/) - Shares av.db curated category or tags: cli, macos, media. - [fx-upscale](https://www.automicvault.com/ja/pkg/brew/fx-upscale/) - Shares av.db curated category or tags: cli, macos, media. - [gphoto2](https://www.automicvault.com/ja/pkg/brew/gphoto2/) - Shares av.db curated category or tags: camera, cli, media. - [iconsur](https://www.automicvault.com/ja/pkg/brew/iconsur/) - Shares av.db curated category or tags: cli, macos, media. - [imageoptim-cli](https://www.automicvault.com/ja/pkg/brew/imageoptim-cli/) - Shares av.db curated category or tags: cli, macos, media. - [libicns](https://www.automicvault.com/ja/pkg/brew/libicns/) - Shares av.db curated category or tags: cli, macos, media. - [makeicns](https://www.automicvault.com/ja/pkg/brew/makeicns/) - Shares av.db curated category or tags: cli, macos, media. - [gifcap](https://www.automicvault.com/ja/pkg/brew/gifcap/) - Both packages work with overlapping file formats or content types.
