This month's technical report provides detailed information on the PowerShot G16, which features an approx. 12.1 effective megapixel (max.), high-sensitivity 1/1.7 type CMOS sensor and a 5x zoom lens (35mm film-equivalent focal length range: 28-140 mm) with a lens shift-type image stabilization system.

Development objective

As the successor to the G15, the PowerShot G16 (Photo 1) camera was designed to provide even higher image quality and performance by combining an approx. 12.1 effective megapixel (max.) 1/1.7 type CMOS sensor (back-lit type) with a DIGIC 6 imaging processor.

The development objective was as follows:

A high-end compact digital camera with outstanding picture quality and performance

Feature 1 - Even better image quality

High-sensitivity CMOS sensor

The G16 has a new back-lit type high-sensitivity CMOS sensor (1/1.7 type, approx. 12.1 effective megapixels), designed to produce optimum results in conjunction with the Canon lens and DIGIC 6 imaging processor.

Canon lens maximizes the benefits of the 1/1.7 type image sensor and DIGIC 6 imaging processor

Like the PowerShot G15, the G16 is fitted with an f/1.8 (max. wide angle) to f/2.8 (max. telephoto angle) 5x zoom lens with a 35mm-equivalent focal length range of 28-140 mm.

DIGIC 6 imaging processor

The newly developed DIGIC 6 imaging processor, also included in the PowerShot SX280 HS, offers the following improvements over the DIGIC 5.

  • Higher picture quality (higher resolution still images and improved noise reduction whether shooting still photos or movies, 60 fps frame rate for smoother, higher-quality movies)
  • Dynamic IS (Compensation for tilt distortion and distortion when shooting movies)
  • MP4 (MPEG-4) recording format in movie mode (full-HD movie frame rate: 60/30 fps)
  • Improved user-interface display screen (higher quality)
Optical image stabilizer with three-step compensation

The optical image stabilizer of the G16 compensates for blurring due to hand movement, etc.

Note that the Camera & Imaging Products Association (CIPA), a Japanese industry standards organization, enacted standards for Measurement and Description Method for Image Stabilization Performance of Digital Cameras in July 2013; as a result, methods for measuring and describing image stabilization have changed.

For this reason, the description of image stabilization performance differs from those of previous models. In practice, the performance is better than that of the PowerShot G15.

Shorter shutter release time lag because of faster autofocusing

The autofocus and shutter release times have been shortened to approx. 59 percent (at an equivalent focal length of 28 mm) that of the PowerShot G15 thanks to improvements to the AF algorithm, a revised processing sequence, and further improvements to mechanism control (Figure 1).

Records in MP4 (MPEG-4) format in movie mode

Like the PowerShot SX280 IS, the PowerShot G16 records movies in MP4 format (video compression codec MPEG‐4 AVC/H.264, audio compression codec MPEG - 2 AAC - LC).

High noise reduction even at the frame rate of full-HD 60 fps enables movie capture with even less noise.

New Star mode added

The PowerShot G16 comes with a new Star mode, composed of three separate photography and movie modes allowing users to capture a starry night sky easily when using a tripod.

The menu now includes a Night Display option, which darkens the LCD screen on the user interface so that checking the image on the screen while photographing stars will not affect the eyes that have become accustomed to the dark.

Photo 2: Star Trails

  • Star Nightscape
    This mode allows stars and night scenery to be shot together at their best exposure.
    Star Nightscape separates a single image into multiple areas and adjusts the image processing for each according to brightness, so that starry skies and nocturnal city lights can be portrayed in a single shot. Image processing that emphasizes the brightness of stars can be set in the Menu.
  • Star Trails
    Star Trails captures the trails of stars by taking repeated shots for an extended period as the night sky wheels overhead, and then synthesizing the images into a single shot (Photo 2).
    The mode works by shooting repeatedly at the exposure used for the first shot image, then combining the bright areas from the series of shots taken to generate a single image. The shooting time can be set in 10-minute units, from 10 minutes up to 2 hours.
  • Star Time-Lapse Movie
    In this mode, the camera repeatedly takes still images of the night sky and combines them to create a time-lapse movie. Each frame of the movie is a still photograph taken at the exposure used for the first shot image once per minute.
    The end result is a full-HD movie in MP4 recording format, with a frame rate of 15 fps. A recording time of 1 hour, 1.5 hours or 2 hours can be selected, producing movies of 4, 6, or 8 seconds respectively. Sound is not recorded.

Background Defocus

Background Defocus mode enables users to soften backgrounds for photos just like those captured by single-lens reflex cameras with large image sensors.

It works by taking two photos in succession with one click of the shutter button, then analyzing them to identify the main subject and generate a single photo that keeps the subject in focus while defocusing the background (Photo 3). The degree of background blur can be selected, with Auto, Low, Medium and High defocus settings.

New creative sub-modes added to High Dynamic Range mode

With High Dynamic Range (HDR) imaging, the camera captures high-contrast scenes with a greater range of light and shadow detail, by taking three images at different exposures for a single shot and combining them automatically. This enables excessively light and dark areas to be controlled in high contrast scenes.

The PowerShot G16 adds five creative sub-modes to this mode: Natural, Art Standard, Art Vivid, Art Bold, Art Embossed (Photo 4)

A new advanced algorithm makes it possible to adjust the relative positioning of these three images, so that some scenes can be shot handheld in HDR mode.

Addition of still images to digest movies in Hybrid Auto

Hybrid Auto is a new Auto mode, introduced in 2013, which integrates the former Movie Digest and Auto modes. The PowerShot G16 features an upgraded version.

When generating clips in Movie Digest mode, the camera adds a still shot captured after the movie clip along with a shutter-click sound effect. The still shot is displayed for one second, during which time the shutter sound is inserted.

Faster continuous shooting

Previously, Continuous Shooting on PowerShot G, S and SX Series cameras featured normal (High-speed Burst / High-speed Burst HQ), AF, and LV modes, which are selected according to the application.

On the PowerShot G16, parallel image processing is carried out alongside the DIGIC 6 high-speed processing, achieving a much higher continuous shooting rate for up to 522 consecutive frames* (Figure 2)

*According to Canon UHS-I speed test, when using an 8GB card

Shutter speed range up to 250 sec.

In M shooting mode, shutter speeds of up to 30 sec. (up to 250 sec. at ISO 80 setting) are possible.

Feature 3 - More comfortable operation

Improvements to manual focus

2x and 4x zoom display across the entire LCD monitor has been added for easier manual focusing when shooting night skies, etc. When the focus frame is moved, the focus frame in its new position is shown enlarged.

Another new addition is focus peaking for manual focus, a familiar feature from the VIXIA [A] / LEGRIA [E] digital camcorder series. The area of the picture in focus is shown outlined with a colored line, making it easy to focus manually whether in still or movie mode.
