Introduction

The Cam it! - RX64M Camera Solution Kit demonstrates the Renesas RX64M inter fac e d wit h a color CMOS Camera module. Firmware provides human detection, image correction and movement detection. The user interface is a webpage displaying JPEG encoded images, served over a wired Ethernet connection.

The Cam it! - RX64M Camera Solution Kit is supplied with pre-programmed firmware. This QSG covers the setup and the operation of this kit. Please refer to R20AN0385EG Cam it! - RX64M Camera Solution Kit Application Note for details of setting up the development environment and using an E1 debugger.

Fitting the Camera

Insert the camera module in to J23 of the main assembly. Ensure Pin 1 of the Camera Module is aligned with Pin 1 of the main assembly:

Network Connection:

The Cam it! Kit is supplied with a straight through RJ45 Ethernet cable. This can be connected to the development PC via an Ethernet Hub/Switch, or connected directly to the development PC if it supports Auto-MDIX (automatic crossover).

USB Connection:

Using the supplied USB A to Micro-B cable connect the Cam it! Kit to a spare USB port on the development PC. This is used to supply power. The software takes about 50 seconds to complete its startup process. When the device is ready to use LED3 will start to flash.

Configuring the Development PC

The Cam it! Kit uses an IP address of 192.168.1.3, the development PC needs to be given a static IP address to communicate with the Cam it! Kit.

Windows™ 7, 8 & 10:

1) Press + keys together to display Windows™ desktop,

2) Right click on the network icon found on the right of the task bar. This will be or if a wireless network is also connected,

3) Click ,

4) Click ,

5) Right Click on the Network Connection which is connected to the Cam it! Kit and select ‘Properties’,

6) In the Properties window select and click ‘Properties’.

7) Click ‘Use the following IP address’ and enter the details shown below:

8) Click ‘OK’ and then ‘Close’.

Running the Demonstration

The Cam-IT! CPU board ‘GR KAEDE’ has 4 User LEDs, in addition to the Power LED.

A list of demonstration pages available on the Renesas Embedded Web Server will be shown, similar to the image below:

Click on ‘demo_top.htm’ to open the main demonstration page.

At the end of the demo_top page is a series of four blue buttons, each of which will launch a different feature of the

demonstration.

Normal Capture

Images captured by the Cam-it! Camera Module are JPEG encoded and streamed to the Web Browser. The JPEG Quality can be set in this page, this is also applied in the Human & Moving detection demonstrations.

User Parameters:

JPEG Quality: 1 to 128. Quality of the encoded JPEG image. 1 – Lowest Quality, 128 – Best Quality. IMAGE SENSOR REG-WT: Read and write control registers from the camera module. See Application Note for further details.

After entering each value, click the ‘Set’ button immediately below the value to accept the change.

Human detection

Demonstrates the moving Human Body Detection feature. The Human Detection algorithm runs on images constantly captured by the Camera Module. This algorithm looks for movement and determines if the movement is from a human. The area of any humans detected is highlighted by a red and green box on the displayed image

The capture screen is divided in to nine separate areas. To the right of the image is a count of the bodies detected in each area.

User Parameters:

Threshold: 1-9. Discrimination threshold for a moving body. Sensitivity: 1-15. Amount of difference between images that is considered as movement.

After entering each value, click the ‘Set’ button immediately below the value to accept the change.

Moving detection

Continuously captures images, identifying and highlights movement in the field of view. A red highlight is applied over each area of the image where movement is detected. A red and green box is shown around an area of movement detected as a moving object.

The capture screen is divided in to nine separate areas. To the right of the image is a count of the moving objects detected in each area

User Parameters:

Threshold: 1 to 10. Discrimination threshold for a moving object. Sensitivity: 1 to 10. Amount of difference between images that is considered as movement.

After entering each value, click the ‘Set’ button immediately below the value to accept the change.

Distortion correction

Compensates for Horizontal and Vertical distortion of the captured image. This is useful to compensate for distortions associated with camera optics, especially with wide-angle lenses.

Once set in this page, the compensation is also applied in the Human & Moving d et ec ti on dem o nst r ati o ns.

User Parameters:

Function Valid: 0 – Disables Correction; 1 – Enables Correction H-Correction: -127 to 127. Horizontal correction value. V-Correction: -127 to 127. Vertical correction value.

After entering each value, click the ‘Set’ button immediately below the value to accept the change.

Capture stop

Stops capture of images from the camera module. Image capture is restarted by clicking on the required blue ‘START’ button.
