Genio 1200-EVK

Introduction

The following figure shows the architecture of Camera ISP for RAW and YUV sensor on Genio 1200-EVK.

Camera ISP Architecture - RAW sensor

Camera ISP Architecture - 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. For more details, please refer to Sensor Support.	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

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

• RAW sensor.

• YUV sensor.

Sensor Support

Currently, IoT Yocto supports the following sensors:

Sensor Support List

Vendor	Model	Type	Support Platform
Sony	IMX214	RAW	Genio 1200
Onsemi	AP1302 (ISP) + AR0430 (Sensor)	YUV	Genio 350
Onsemi	AP1302 (ISP) + AR0830 (Sensor)	YUV	Genio 1200, Genio700

The user who wants to use other sensors will need to integrate the sensor driver. For more details, please refer to the sensor porting guide on MediaTek On-Line:
