  • Page 7: Development Background

    Compatible with Macro Twin Light MT-24EX 1–2 Product Concepts The PowerShot G3, successor to the PowerShot G2, aims to be the top in its class in terms of picture quality by employing a 1/1.8-inch, 4-megapixel-class CCD and incorporating a newly developed f/2.0 (wide-angle) “large- diameter lens”...

  • Page 8: High Image Quality

    N: New features unique to the PowerShot G3 (autumn 2002 model) U: Updated features from the PowerShot G2 (already equipped on other models) High Image Quality N - High-resolution large-aperture (f/2.0-3.0) 4x zoom lens (35 mm film equivalent: 35 to 140 mm) N - High definition and fast processing with the newly developed “DIGIC (Digital Imaging Processor)”...

  • Page 9: Operation Ease

    U - Digital zoom continuously changes the field of view (approx. 3.6x ; approx. 14x magnification when combined with optical zoom) U - Super intelligent (SI) sensor automatically detects vertical or horizontal photography U - Magnified playback for easy confirmation of images (from approximately two times to 10x zoom magnification) U - Next frame, previous frame, fast forward, rewind, first frame and last frame end available during movie replay...

  • Page 13 - High-resolution large-aperture (f/2.0 to 3.0) 4x zoom lens (35 mm film equivalent: 35 to 140 The photo lens of the PowerShot G3 is a 4x zoom lens with a focal length of 7.2 to 28.8 mm (35 mm film equivalent: 35 to 140 mm) that permits a wide range of photography from scenery to snaps.
  • Page 14 * Once the data is set it is maintained until the white balance is reset. - Super intelligent (SI) sensor improves precision of AE/AWB The PowerShot G3 incorporates the same SI sensor as the IXY DIGITAL 200a/300a. The SI sensor is an orientation detector and can distinguish whether the camera is positioned vertically or horizontally when taking a photo.
  • Page 15 The PowerShot G3 makes it possible for the first time to insert an ND (light reducing) filter. In this way, a wider aperture than usual can be used even in bright conditions to produce blur effects (see Photograph 2–2A). By stopping down the aperture to slow the shutter speed, so-called slow shutter effects can also be obtained (see Photograph 2–2B).
  • Page 16 - Interval shooting function for fixed-point observation over long periods The PowerShot G3 comes with an interval shooting function that can take a sequence of photos at fixed time intervals. As a result, fixed-point observation over long time periods (100 hours maximum) can be achieved.
  • Page 17 In order to handle these situations, the PowerShot G3 has been specified so that the flash output can be set manually. When using external flash units, the exposure can be adjusted in one-third stop intervals from full exposure to –4 stops (see Table 2–2).
  • Page 18 On the PowerShot G3, two positions on the mode dial are reserved for “custom” modes so that users can store their preferred modes and parameters. In this way, it is not necessary to adjust settings for each photo.
  • Page 19 (selectable from QVGA and QQVGA) The PowerShot G3 can record moving images at 15 frames per second along with audio in two formats, QVGA (320 by 240 pixels) and QQVGA (160 x 120 pixels). Because a method is employed that consecutively writes images that are temporary stored in the buffer to the CF card while recording, long continuous filming times are also achieved.
  • Page 20 1/1250 second even when the full aperture. - Built-in flash with five controls and improved usability (slow sync response) For the PowerShot G3, the order of the flash modes set previously with a toggle movement (auto auto red- eye reduction...
  • Page 21 The PowerShot G3 can adjust the field angle by up to a maximum of 14 times (35 mm film equivalent: 35 to 490 mm) by combining a 3.6-times digital zoom magnification with the optical four-times zoom lens.
  • Page 22 - Magnified playback for easy confirmation of images (from approx. 2x to 10x zoom magnification) During replay on the PowerShot G3, the image can be magnified from 2 to 10 times with the image magnification control. Because zooming has been made possible, the image is magnified in a continuous fashion.
  • Page 23 895PD, BJ 535PD and BJ F890PD The direct printer function has been added to the PowerShot G3 so that high-picture-quality prints can be made easily by merely connecting the camera with the supplied cable to Canon’s CP-10 card photo printer, the L-size and postcard-size compatible CP-100 or a Bubble Jet printer (BJ 895PD/BJ 535PD/BJ F890PD).
  • Page 24 Along with providing a new electronic dial on the PowerShot G3, the two-stage main dial/mode dial construction employed on the PowerShot G1 and G2 has been abandoned and each function has been made independent. In particular, the main dial separates the functions of the mode lever and OFF button, and the power on and shooting/replay selection function have been given* to the mode lever.
  • Page 25 - Manual focus adjustment with better usability Although it is possible to adjust the focus manually while viewing the LCD monitor on the PowerShot G3, it is sometimes difficult to bring the subject into focus on the LCD monitor due to patterns and designs on the subject.
  • Page 26 - One-touch reset of all settings The PowerShot G3 includes a function to return all user settings* made on the LCD monitor to their default conditions with one touch. Pressing the menu button continuously for five seconds brings up the reset dialog.

  • Page 27: System Accessories

    - New wide converter and telephoto converter configurations The optical accessories are being enhanced for the PowerShot G3 to respond to the diverse needs of users. With the WC-DC58N Wide Converter, which converts the focal length of the master lens by a factor of about 0.7, the focal length after mounting becomes approximately 24.5 mm (wide-angle setting, 35 mm film equivalent).
  • Page 28 - Support for EOS-type EX Speedlites (including the MT-24EX Macro Twin Lite) The PowerShot G3 makes it possible to use the MT-24EX* Macro Twin Lite for macro photography in addition to the EX Speedlites (including the MR-14EX Macro Ring Lite) developed for use with EOS cameras.

  • Page 58: Isap (Intelligent Scene Andlysis Based On Photographic Space) Technology

    6 Additional Guidance 6–1 iSAP (intelligent Scene Analysis based on Photographic Space) Technology An important role of copiers and scanners is to faithfully reproduce the image quality of the original. With digital cameras, on the other hand, it is essential to regenerate captured images naturally. However, attempting to faithfully reproduce a captured image does not always result in a natural image.
  • Page 59 For more than 60 years since its inception, Canon has been asking ‘how can we take better pictures?’ As it has progressed, Canon has built up a tremendous database of know-how on photography as a result of its camera developments. From this photo data covering an enormous number of frames, Canon has classified statistically the frequency that users take certain photos and created a ‘Photographic Space’...
