Genio 510/700-EVK

There are two camera architectures supported by Genio 510/700-EVK. One is MediaTek Imgsensor, and the other is V4L2 Sensor. For the camera usage, please refer to the below sections.

MediaTek Imgsensor 

The following figure shows the MediaTek Imgsensor architecture with the camera ISP and RAW/YUV sensors.

../../../../_images/sw_yocto_app-dev_yuv_camera_arch.svg — MediaTek Imgsensor - YUV Camera

The Camera ISP feature includes 4 major components:

Camera ISP Feature Components
Item	Description	Repo Path
Sensor Driver	The Linux kernel driver under MediaTek Imgsensor architecture controls the sensor. It’s maintained in the out-of-tree repository.	mtk-camisp-driver/drivers/misc/mediatek/imgsensor
ISP Driver	The Linux kernel driver controls MediaTek camera ISP hardware. It’s maintained in the out-of-tree repository.	mtk-camisp-driver/drivers/media/platform/mtk-isp
Camera Middleware	The binary-released userspace library controls the whole ISP devices, manages buffers and streams, and exports MediaTek proprietary 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 transfer 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 

The following figure shows the 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.
