CHAPTER 1. GENERAL DESCRIPTION OF PRODUCT CONTENTS 1. Development Concept 1-1 Development Objectives --------------------------------------------------------------------------------------------------- 1-1 1-2 Product Concept ------------------------------------------------------------------------------------------------------------- 1-1 1-3 Design Concept -------------------------------------------------------------------------------------------------------------- 1-3 2.
1. Development Concept 1-1 Development Objectives Canon has marketed the standard compact PowerShot A-series and S-series, the ultra-compact IXY series, the full-featured PowerShot G-series, and the top-end PowerShot Pro-series. In recent years, our competitors have concentrated on offering low-cost models to expand their market share as they target low-end user segments.
High Image Quality • Primary color filter and adaptive signal processing for maximum effect • High-resolution, 1/2.7-inch type, 2.11-megapixel CCD (PS A20), 1/2.7-inch type, 1.
System Accessory and Software • Optical accessories (with conversion lens adapter) • Wide Conversion Lens for taking 24.5mm (35mm format equivalent) wide-angle shots. • Close-up lenses for close-ups, and any other 52mm filters • Waterproof case good to 30 m underwater • Smaller battery charger • Compact power adapter also compatible with the IXY DIGITAL 300 • Nickel hydride Battery and Battery Charger • Full-featured application programs • Easy-to-use ZoomBrowser EX 2.6 (Windows)/ImageBrowser 1.
2. Features 2-1 High Image Quality ! Primary color filter and adaptive signal processing for maximum effect From the PowerShot 600 onward, Canon has employed a complementary color (Cy, Mg, Ye, G) filter as the CCD onchip filter to obtain color. Since the complementary color filter uses light efficiently, it makes the light sensitivity very good. It thereby helps to improve the SN ratio (especially the luminance).
! High-resolution, 1/2.7-inch, 2.11-megapixel CCD (PS A20), 1/2.7-inch, 1.32-megapixel CCD (PS A10) To enjoy a digital image as a print, the original image must have the number of pixels matching the print size. Normally, a regular size print requires 1.3 megapixels, a postcard-size print needs 2 megapixels, and a 5x7 in. print must have 3 megapixels to attain adequate image quality. Since the PowerShot A20 has a 1/2.7-inch, 2.
z Intelligent AE for obtaining optimum exposures Compared to silver-halide film, the CCD’s exposure latitude is narrow. Even a slight exposure error will eliminate highlight or shadow detail, resulting in lower image quality. To obtain highly precise exposures, previous digital cameras have used feedback AE, multi-zone metering, meter weighting control, and other exposure control methods.
! Noise reduction function enables high SN ratio Normally with a CCD, the longer the exposure is, the more noise the image will have. With the PowerShot A20/A10 noise reduction is executed automatically. The process of noise reduction is as follows : After the exposure ends, the aperture remains closed and another exposure is taken at same shutter speed used for the preceding shot. This enables the camera to capture only the noise factors as data, and these noise factors are removed from the preceding shot.
2-2 Superior Features and Operation Ease ! Print directly to Card Photo Printer CP-10 The PowerShot A20/A10’s direct print mode enables you to print out images with the dedicated Card Photo Printer CP-10 by connecting the camera to the printer with a dedicated cable. In the playback mode, you just select the Print command in the Print dialog box displayed on the LCD monitor on the camera back. The printer will then print the image. You control the printer High-quality credit with the camera.
z Digital zoom enables the angle of view to vary gradually (PS A20 : 2.5X (Max. 7.5X together with the optical zoom)) (PS A10 : 2.0X (Max. 6X together with the optical zoom)) As with the PowerShot A20/A10, the IXY DIGITAL 300 has a digital zoom. The digital zoom in previous models (PowerShot S10 through Pro90 IS) combined an optical zoom and digital teleconverter. Within the digital zoom range (when the digital teleconverter operates), the CCD’s reading area becomes limited to the center portion.
! Widely available size-AA batteries (Primary battery: Alkaline) (Secondary battery: NiCd*, nickel hydride) To make the camera body more compact, the PowerShot A-series and S-series cameras use a lithium 2CR5 battery or a dedicated, rechargeable Ni-MH battery. The IXY DIGITAL uses a dedicated, rechargeable Liion battery. However, most competing models use size-AA batteries which are favored for their widespread availability and low price. Users also support that size-AA batteries can be used.
! Real-image optical zoom viewfinder The PowerShot A20/A10’s optical viewfinder is a real-image viewfinder consisting of an objective lens with 3 elements in 3 groups, a fully reflective prism to bend the light flux compactly, a roof prism to right the inversed image formed by the objective lens bending the light flux, and an eyepiece lens. This optical viewfinder is coupled to the lens zooming operation. Thus, the viewfinder image also zooms during lens zooming.
! Shutter speeds from 1 sec. to 1/1500 sec. The PowerShot A20/A10 boasts the fastest shutter speed in its camera class with 1/1500 sec. This shutter speed can freeze a fast-moving subject quite well. Also, with the f/13.4 aperture (at the telephoto end), the camera can take pictures of scenes as bright as EV 18. This is suitable for a sunny beach and ski slope. The slowest shutter speed of 1 sec. and the f/2.7 aperture (at the wide-angle end) enable the camera to photograph scenes as dark as EV3.
2-3 Power-saving Design z New and compact digital signal processing IC and CPU with low power consumption The PowerShot A20/A10 uses a new digital signal processing IC which is an improved 16 x 16 19 x 19 13 x 13 13 x 13 version of the digital signal processing IC found in the PowerShot S10 and later models. Digital signal Digital signal The new digital signal processing IC features processing CPU CPU processing IC IC high performance and sophisticated functions in a compact package.
! High-performance, red-eye reduction with power-saving LED For red-eye reduction in flash pictures, the PowerShot A20/A10 has a red-eye reduction lamp in the flash unit. To reduce the chances of red eye occurring in the human subject, the red-eye reduction lamp lights before the flash fires. The red-eye reduction lamp is a bright, high-performance, orange LED with low power consumption.
2-4 Accessory and Software ! Abundant optical accessories (Conversion Lens Adapter required) • Wide Conversion Lens for taking 24.5mm (35mm film equivalent) wide-angle shots Wide Conversion Lens WC-DC52 has been newly developed so that the PowerShot A20/A10 can take wide-angle shots not possible with the 35-105mm (35mm film equivalent) lens. The WC-DC52 reduces the camera lens focal length to 0.7x which affords a wide-angle effect equivalent to 24.5mm in the 35mm format.
! Full-featured application programs • Easy-to-use ZoomBrowser EX 2.6 (for Windows)/ImageBrowser 1.6 (for Macintosh) The ZoomBrowser EX (for Windows) and ImageBrowser (for Macintosh) programs marketed at the same time as the PowerShot S-series cameras were well received. Upgraded versions (ZoomBrowser EX 2.2/ImageBrowser 1.2) of both programs were offered when the IXY DIGITAL came out. For the PowerShot G1, ZoomBrowser EX 2.4 and ImageBrowser 1.
• PhotoStitch 3.1 for seamless panoramic photos Pictures taken in the stitch assist mode can be used to create a long panoramic picture with PhotoStitch 3.1. This program automatically obtains the camera’s property information (compositing orientation, image sequence, focal length, and camera model name) used to stitch the images together. The operation is easy, yet highly precise.
