Genio 510/700-EVK

Important

All the bash commands shown here are based on Genio 700-EVK. For Genio 510-EVK, users can follow the same step to do the whole setup with changing the naming term from 700 to 510.

The end user can operate the camera through the V4L2 devices exposed. For the usage, please check the following sections.

• YUV sensor.

MediaTek Imagsensor Architecture

The following figure shows the MediaTek Imgsensor architecture with the camera ISP and YUV sensor.

MediaTek Imgsensor - YUV sensor

The Camera ISP feature includes 4 major components:

Camera ISP Feature Components

Item	Description	Repo Path
Sensor OOT Driver	The sensor drivers under MediaTek proprietary imgsensor framework. It’s maintained in the out-of-tree repository.	mtk-camisp-driver/drivers/misc/mediatek/imgsensor
Camera ISP OOT Driver	The drivers, camsys and imgsys, for MediaTek proprietary camera ISP hardware. It’s maintained in the out-of-tree repository.	mtk-camisp-driver/drivers/media/platform/mtk-isp
Camera ISP Middleware	The binary-released userspace library controlling the whole ISP devices, managing buffers and streams, and exporting MediaTek proprietary user interface.	mtk-camisp-prebuilts (Require NDA)
V4L2 Adapter	The V4L2 Adapter contains the binary-released userspace executable and source-released kernel driver. The executable, camd, is a service daemon. It uses the middleware library to control the camera and transfers image buffers to the adapter driver. The driver, mtk-camera, provides the V4L2 interface which can be used by OSS tools, such as v4l2-utils, GStreamer, OpenCV, etc.	mtk-camisp-prebuilts (Require NDA) mtk-camisp-driver/drivers/media/platform/mtk-camera

V4L2 Sensor Architecture

The following figure shows the standard V4L2 sensor architecture with the YUV sensor. The sensor driver and the camsys driver follow the V4L2 framework. The user can access the video device node created by the camsys driver to get the pipeline stream on.
