: For developers needing wireless control on mobile platforms (Android/iOS) or Linux (including Raspberry Pi), Canon offers the CCAPI , which communicates over Wi-Fi via HTTP.
The EDSDK provides a C-based Application Programming Interface (API) that bridges the gap between your application software and the camera's internal firmware. By using the EDSDK, you can bypass standard webcam protocols (like UVC) and Generic Media Transfer Protocols (MTP) to access low-level, high-performance camera functions. Core Capabilities
: Fires when a new file is created (e.g., after taking a picture).
| Module | Purpose | |--------|---------| | EdsInitializeSDK / EdsTerminateSDK | SDK lifecycle | | EdsGetCameraList | Detect connected cameras | | EdsOpenSession | Start control session | | EdsSendCommand | Press shutter, change UI lock, etc. | | EdsDownloadImage | Transfer images after capture | | EdsCreateMemoryStream | Handle image data |
Query file metadata (filename, size) using EdsGetDirectoryItemInfo .
: Establish a connection using EdsOpenSession(camera) . All commands require an active session.
: Submit a request for the EDSDK; approval is usually required before download links are provided.
Stream live view data to a computer monitor or download captured images directly to a local hard drive.
Represents the memory card or storage medium inside the camera.
: Extract the visual bytes to display in your UI.
Represents all Canon cameras currently connected to the computer.
Numeric definitions for camera properties and error management (prefixed with EDS_ERR_ ). The EDSDK Programming Guide
To talk to a camera, you must first initialize the SDK and retrieve the camera list.
Taking a photo requires sending a specific command to the camera device handle.
Canon does not host the EDSDK as a public open-source repository. To get the official documentation and binaries:
: Check the official compatibility chart within the developer portal to ensure your camera model is supported (most EOS DSLRs, mirrorless, and select PowerShot models are). 2. Environment Setup
Automatically download images and videos directly to local storage or memory buffers upon capture.
