The RZ/V Series has two version of the Image Signal Processor (ISP)

RZ/V2L Simple ISP (Memory)

The Simple ISP uses a working memory area for processing camera streams. This working memory area is defined in the device memory space define ISP Reserved memory area ( see Figure ). In the Application Layer uses the Video 4 Linux API (VIDIOC_REQBUFS, VIDIOC_QUERYBUF) to allocated memory. How much of this memory is used is defined by the camera device resolution, pixel color depth, and capture frame buffer count. The ISP revered memory space is defined in the RZV2L Linux Device Tree File ( r9a07g04512-smarc.dts ).

RZV2L BSP v1.0.1 Memory Area

OV5645 Supported Resolutions
Width	Height	Pixel Depth	Number Frames	Total Memory Usage
640	480	2	6	3,686,400
1280	720	2	6	11,059,200
1920	1080	2	6	24,883,200
2592	1944 *1	2	6	60,466,146 *2

1 ) Maximum Resolution for OV5645. For AI inference please uses smaller resolution.

2 ) Due to the BSP v1.0.1 ISP resaved area size ( 48MB ) this resolution is not supported. The reserved memory needs to be increased.

RZ/V2L Simple ISP Monitor Demo

RZ/V2L ISP Sample Camera Demo

This demo show how to implement the RZ/V2L Simple ISP with OV5645 Cameras. This expands on the RZ/V2L ISP Sample Application that is included with the RZ/V2L ISP Package with all the resolutions listed in the section above.

Requirements

Linux BSP SDK : The SDK must include the DRP-AI and ISP packages. Refer to Linux BSP Release Note instructions (r01an6221ej<version>-rzv2l-linux.pdf) Section 6.
RZV2L DRP-AI Sample Application : ( rzv2l_drpai-sample-application_ver5.00.tar.gz )
Power : A powered hub or PC may not provide sufficient power. A USB Power Block is suggested.

Build ISP Monitoring Application

Detailed instructions for setup and building are located in the Application Note Revision documents in "Simple ISP Sample Application Note Revision" package.

⚠️ You must first follow the Simple ISP Sample Application Note Revision instructions (r11an0563ej<version>-rzv2l-simple-isp.pdf) Section 2.0 and 2.6
