What is this ?
This is a sample program that displays the image captured by the camera to the LCD by using the GR-PEACH AUDIO CAMERA Shield and GR-PEACH LCD Shield.
This program displays the NTSC input from NTSC1A on the screen of LCD shield.
When you touch on the screen of LCD Shield, the touch coordinates are displayed on the PC terminal software. You can touch the two points at the same time.
Inaddition, while you press USER_BUTTON0, th image is saved to the USB memory.

When you save a camera image to a USB memory, the image is converted along the following conversion method.
| Value of "VIDEO_INPUT_FORMAT" in main.cpp | Conversion method |
| VIDEO_YCBCR422 | JPEG |
| VIDEO_RGB888 | bitmap |
| VIDEO_RGB565 | binary (RAW data) |
If you use a USB, according to the USB port to use, make the following changes and the jumper short.
(define 0:USB0、define 1:USB1)
USBHost\USBHost\TARGET_RENESAS\TARGET_RZ_A1H\usb_host_setting.h
#define USB_HOST_CH 0 ↓ #define USB_HOST_CH 1
If you use the GR-PEACH's USB connector (USB0), please close GR-PEACH's JP3.
If you use the GR-PEACH AUDIO CAMERA Shield's USB connector (USB1), please close Audio/Camera Shield's JP1.

概要
GR-PEACH AUDIO CAMERA ShieldとGR-PEACH LCD Shieldを使って、カメラで取り込んだ画像をLCDへ表示するサンプルプログラムです。
このプログラムは、NTSC1AからのNTSC入力をLCDシールドの画面上に表示します。
画面をタッチすると、タッチ座標がPCターミナルソフト上に表示されます。2点まで同時にタッチできます。
また、GR-PEACHのUSER_BOTTON0を押している間、カメラで取り込んだ画像をUSBメモリへ保存することができます。

カメラ画像をUSBメモリへ保存する際、以下の変換方法に沿って変換を行なって保存します。
| main.cpp内の"VIDEO_INPUT_FORMAT"の値 | 変換方法 |
| VIDEO_YCBCR422 | JPEG |
| VIDEO_RGB888 | bitmap |
| VIDEO_RGB565 | binary (RAW data) |
USBを使用する場合、使用するUSB口に合わせて、以下の変更とジャンパーショートを行なって下さい。
(define 0:USB0、define 1:USB1)
USBHost\USBHost\TARGET_RENESAS\TARGET_RZ_A1H\usb_host_setting.h
#define USB_HOST_CH 0 ↓ #define USB_HOST_CH 1
GR-PEACH側のUSB0を使用する場合は、JP3をショートして下さい。
GR-PEACH AUDIO CAMERA Shield側のUSB1を使用する場合は、JP1をショートして以下の変更を行なって下さい。
