2.3.1 Frame Size
Three JPEG frame sizes are supported by the GV1000. They are QVGA (320x240),
VGA (640x480), MPixel (1280x1024).
2.3.2 Input Color Space
Currently the GV1000 does not support configuring the Input Color Space and the default
setting is YUV 4:2:2. In future releases there may be support for YUV4:2:0 which will
reduce the bit rate although also reducing the JPEG image quality.
2.3.3 Compression Level
There are three supported JPEG Compression Levels, Low, Medium and High. Low
compression will create the largest JPEG data size and also the best quality image.
Medium compression will create the best combination of image size and quality. High
compression will create the smallest data size and the lowest quality image. Unless
restricted by bit rate or available data storage either Medium or Low compression should
be used.
2.3.4 Encode Source
JPEG encoding may originate from the GV1000 sensor for live capture or in future
releases from a file in YUV4:2:2 format.
2.3.5 Restore Defaults
Used to restore JPEG encoder defaults: VGA Frame Size, YUV4:2:2 Image Color
Space, Medium Compression Level and the Sensor Encode Source.
2.3.6 Capture
This button is used to take a JPEG image with the GV1000. After pressing the Capture
button the user will be prompted to specify which folder to store the received JPEG
image.
