Canon iSAPS technology

Mark Peters : 2005-10-11 23:28:22
Canon iSAPS technology : Canon has collected a huge volume of photographic data and made extensive statistical analyses of the frequency of taking photographs. Based on this data, we created Photographic Space, a graphical database of information about the correlation between surrounding brightness and distance between camera and subject according to the focal length and zoom lens position when pictures are taken. Canon developed a scene-recognition technology called "iSAPS" (intelligent Scene Analysis based on Photographic Space) Technology. Canon iSAPS Technology envisages the scene to be photographed and makes optimal adjustments of key functions, such as AF, AE and AWB, before the shutter is pressed.

Canon ChromaLife100 system introduction

Ilse Jurriën : 2005-07-11 18:30:00
Canon ChromaLife100 system introduction : Canon, a leader in photographic and imaging technology, today announced a fundamental shift in focus for communicating printer speed performance to reflect the rapidly growing trend in personal photo printing. Leveraging the advantage of the company's patented FINE (Full-photolithography Inkjet Nozzle Engineering) print technology, Canon will use print times when producing photo lab-quality prints as a new print-speed performance benchmark for all new PIXMA desktop and all-in-one photo printers. Canon also introduced the new ChromaLife100 system for photo longevity, making possible a level of fade-resistance rivaling many traditional film-based prints.

Canon low pass filter explanation

Dennis Hissink : 2005-02-17 12:00:00
Canon low pass filter explanation : Certain fabrics can have a very tight, regular weave. On close inspection, this can appear as a series of alternating stripes separated by dark shadows between the weave. When the pitch of this weave is close to a digital camera sensor's pixel pitch, light from the subject will only activate selected rows of pixels. The sensor will then produce false colours, which can change with rotation or lateral movement of the camera. These false colours appear as waves on the image, known as moiré. Subjects such as distant geometric patterns are also susceptible to producing this effect. To combat the effects of moiré, camera manufacturers sometimes utilize a low pass filter to blur incoming light.
