DIGIC in Cameras


Original DIGIC

The original DIGIC was used on the PowerShot G3 (Sep 2002), Canon S1 IS (Mar 2004), A520 (Mar 2005), and other cameras. It consists of three separate chips: a video processing IC, an image processing IC and a camera control IC.


DIGIC II

DIGIC II is a single chip system introduced in 2004, unlike the first DIGIC, that allowed for more compact designs. DIGIC II also improved upon the original by adding a larger buffer and increasing processing speed. It has been used in some advanced consumer-level cameras and many digital SLRs such as Canon EOS 5D and Canon EOS 30D. DIGIC II uses high-speed

It also provides higher resolution for their LCD screens. Additionally it has a 14-bit A to D converter providing greater bit depth than previous versions.


New features

DIGIC III provides face detection AF/AE, which finds and tracks up to nine faces at once and controls exposure and flash to ensure proper illumination of the faces as well as the rest of the frame, reducing the detrimental effect of overexposed or darkened faces in a photo. It reverts to the AiAF system if the subject is either not detected or not deemed to be a subject (based on the ''iSAPS'' database). The latter is useful at tourist spots where there may be many people around who are not intended to be the subject of the scene.


Scene-recognition

iSAPS is a scene-recognition technology developed by Canon for digital cameras. Using an internal database of thousands of different photos, iSAPS also works with the DIGIC III Image Processor to improve focus speed and accuracy, as well as exposure and white balance.

Dual DIGIC 4

Dual DIGIC 4 processors are used in the EOS 7D and EOS-1D Mark IV.


DIGIC 4+

This processor was introduced in 2014, replacing the DIGIC 5 in some mid-range compact cameras (particularly in the Elph/IXUS and SX series) and later used in budget DSLRs such as EOS 1300D/Rebel T6, EOS 2000D/Rebel T7/EOS 1500D and the EOS 4000D/EOS 3000D/Rebel T100. Full specifications were not made available at introduction, but Canon claims a 60% speed improvement over the original DIGIC 4 on high ISO shots.


DIGIC 5

In 2011, Canon introduced the DIGIC 5. It is featured on Canon compact cameras like PowerShot SX40 HS to achieve a capture rate of 10.3 frames per second at full resolution in High-Speed Burst HQ, Full HD 1080p Videos and Intelligent Image Stabilization. Canon claims the new DIGIC 5 processor is six times faster than the DIGIC 4 processor and efficiently manages the increase in scene information and simultaneously reduces the appearance of image noise by up to 75%. According to Canon, DIGIC 5 analyses four times more image information to create each pixel, recording more detail and colour from a scene than ever before. DIGIC 5 was co-designed with

DIGIC 5+

DIGIC 5+ is an enhancement to the DIGIC 5 and DIGIC 4. The performance is said to be 17x the performance of the DIGIC 4. The additional processing power allows for higher frame rate in continuous shooting (burst) modes, and greater noise correction through the use of signal processing. DIGIC 5+ is used in the EOS-1D X, EOS 6D, EOS 5D Mark III and the EOS 70D.


Dual DIGIC 5+

The EOS-1D X includes dual DIGIC 5+ processors, allowing for a capture rate of 12 frames per second in RAW + JPEG, and an additional DIGIC 4 processor specifically for its Intelligent Subject Analysis System.


DIGIC 6

Introduced in 2013, the DIGIC 6 image processor enables improved low-light performance up to ISO 6400, with reduced noise. In addition, it enables improved AF times and reduced lag over previous models. The improved performance allows for shots at up to 14 fps. Further advancements attributed to DIGIC 6 can be experienced in movie mode, which records in MP4 format and doubles the frame-rate to 60 fps at 1080p. It also features reduced noise at 30 fps and improved image stabilization. DIGIC 6 is used in EOS 750D/Rebel T6i, EOS 760D/Rebel T6s, EOS 80D, PowerShot G16, PowerShot N100, PowerShot S120, PowerShot SX270 HS, PowerShot SX280 HS, PowerShot SX60 HS, PowerShot SX700 HS, PowerShot SX710 HS and PowerShot SX720 HS.

), 1 Gig video-size limit removed in earlier cameras, Shutter, Aperture, and ISO overrides (shutter speeds of 64" to 1/10,000" and higher). For the CHDK project to augment or extend firmware, it was necessary to obtain copies of the cameras' original firmware; in some cases this can be done via a pure software method, while others rely on a method of using a blinking LED on the camera as an optical serial port to transmit the firmware to a host computer. However, to install precompiled firmware on a PowerShot camera, it is only necessary to download the correct binary and copy it to an SD memory card. If the SD card is set to lock and the boot flag is enabled when the camera is turned on, the camera will autoboot from the binary file on the card and CHDK will be loaded into the camera's RAM. If the card is unlocked or removed, the camera will start up in the original Canon firmware. CHDK will mask the lock on the SD card so that the camera will still write to it however. Alternatively, CHDK can be loaded manually from the Canon menu. CHDK is released under the

Magic Lantern

Magic Lantern is a firmware add-on written for the Canon 5D Mark II by Trammell Hudson in 2009, and ported to the 550D/T2i/Kiss X4 (1.0.8) in July 2010 by the same author. Starting September 2010, A1ex from CHDK forum and other people ported this add-on to the 550D/T2i (1.0.9), 60D, 500D/T1i/Kiss X3, 600D/T3i/Kiss X5 (1.0.1) and 50D; It also runs on the 7D.
