The electronics of the XL1S have many advanced features, including a number of programmed AE modes, as well as both shutter and aperture priority modes. There are two different auto modes, one of which allows you to adjust any setting manually, if you want, and the other, which adjusts every setting automatically and lets you adjust nothing. A spotlight mode automatically compensates for difficulties when shooting a subject bathed in a spotlight. The computer-shooting mode gets rid of monitor flicker that happens when shooting a computer screen. There are also three different shooting modes: normal movie, digital photo, and frame movie. Normal movie mode is for any time you want to shoot video footage. Digital-photo mode records a still image for six seconds on the MiniDV tape and also captures any accompanying audio for a commentary track. The frame movie mode records 30 noninterlaced still images per second, instead of capturing 60 fps interlaced images. This mode isn't intended to be used for shooting video (playback may not look completely smooth). Rather, frame movie mode should be used as a burst, or continuous, shooting mode, like you'd find on a still camera.
The XL1S offers many new and updated features over the XL1. There is a 16:9 shooting mode where electronic lines draw are displayed through the viewfinder so you can compose your shots flexibly for later conversion to HDTV, where 16:9 is the standard. SMPTE color bars help establish a proper color reference for shooting and editing. Interval recording lets you shoot time-elapsed motion video with intervals from 30 seconds to 10 minutes. Zebra patterns help you determine overexposed areas in your shot so you can adjust the aperture and shutter accordingly.
| The MiniDV format supported by the XL1S delivers more than 500 lines of horizontal resolution -- a 25% improvement over analog systems. The DV format allows for near lossless transfer within digital editing environments for faster creation, increased productivity and improved production quality of final prints. |
| The XL1S maximizes the capability of the DV format by using a 3 CCD (charge-coupled device) system with a separate CCD for each primary color (red, green, blue). A beam-splitting prism separates light passing through the lens into individual color components and each is sent to its own CCD. Compared to a single CCD, the 3 CCD system achieves outstanding detail with highly accurate color reproduction suitable for the demands of high-end video production - wide dynamic range, low color noise, high-contrast detail, natural color resolution and low-aliasing. The 3 CCD system also makes advanced Pixel Shift (for increased image quality) and Low Light Recording (for increased flexibility) possible. |
The three CCD image sensors in the XL1S, each with 270,000 pixels, were specifically designed to capture as much image detail as possible and for shooting under extremely low light conditions. The size of each pixel is 72 square microns - 150% larger than the pixel-size on comparable DV models. The result is an approximate 4 dB improvement in sensitivity. This improved sensitivity means that each CCD can capture more information at all light ranges. In super low light, the XL1S still captures crisp and clear digital data. Under extremely bright conditions, the Pixel Shift capabilities of the XL1S greatly reduces vertical white streaks and smears, making it a consummate field recording device for all conditions.
Because human eyes see green more clearly and readily, the green component of a video signal contains 60% of the picture detail whereas the red and blue components together comprise the remaining 40%. With the advanced Pixel Shift on the XL1S, the green CCD is physically shifted the equivalent distance of 1/2 pixel horizontally from the red and blue CCD, and the green signal is electronically shifted 1/2 pixel vertically. This shifting of the green CCD increases the sampling points, resulting in a system that is comparable to 410,000 pixel CCD systems in terms of resolution. With a larger pixel size and the process of Pixel Shift, the Canon XL1S gives wider dynamic range, better low light recording, reduced vertical smears, and high quality still images without sacrificing the highest resolution DV available.
