The PowerShot Pro1 is a digital camera made by Canon, announced in February 2004 and was discontinued first quarter of 2006.It uses a Sony-built 2/3 in (17 mm) 8.3 megapixel CCD image sensor, which gives a usable image size of approximately 8.0 megapixels.
Canon began developing a still video system as early as 1977 following a secret presentation from Texas Instruments (TI). Processing the image data from a CCD sensor into a digital file would have required a supercomputer at the time, so a strategic decision was made to use analog recording methods, and Canon recruited Sony and other manufacturers to create a standard format, resulting in the ...

HDCAM, introduced in 1997, was the first HD format available in Betacam form-factor, using an 8-bit DCT compressed 3:1:1 recording, in 1080i-compatible downsampled resolution of 1440×1080, and adding 24p and 23.976 PsF modes to later models. The HDCAM codec uses non-square pixels and as such the recorded 1440×1080 content is upsampled to 1920 ...

Calculations of DOF assume that an imperfectly focused "circle of confusion" smaller than 0.20 to 0.25 mm is indistinguishable from perfect focus in an image viewed from a normal distance. [7] [12] This is approximately equivalent to 0.03 mm in the case of an image on 35 mm film or FF format. [13] DPI: Dots per inch. A measure of the ability of ...
