The built-in 330K pixel CMOS camera is able to capture photos at sizes of either Small - QQVGA (160 x 120 px), Medium - QVGA (320 x 240 px), or Large - VGA (640 x 480 px) resolutions, while providing 24-bit color depth at 16 million colors.
The left and right navigation keys function as the controls for the 4X digital zoom. It should be noted that digital zoom is not "true" zoom such as optical zoom. A digitally zoomed image will not actually zoom in with the lens, but rather crop the image to make it larger. So picture quality decreases. Due to the compact size of phones, the moving parts required for optical zoom are not yet available.
Additionally, a robust set of camera tools allow users more control and error correction. Features integrated include Self-Timer (5 or 10 seconds), Brightness Adjustment, White Balance (Auto, Sunny, Cloudy, Tungsten, Fluorescent, Darkness), Shutter Sound, Color Effects (Normal, Antique, Black & White, Negative), File Quality Adjustment, Multishot Adjustment, Shutter Sound Adjustment (Shutter, Chime, No Sounds), Mirror (For Self-Portraits), and Flash.
Images taken are stored in the VX6100's internal memory. And memory is dynamically allocated depending a large part on other applications. Thus free space can vary considerably. However, up to 60 photos can be saved in the gallery, and on average, approximate image file sizes are 50 KB for VGA, 16K for QVGA, and 3 KB for QQVGA

i can hold 60 images at the highest res.
