In the US, size names are often denoted with a code of the format nR, where the number n represents the length of the shorter edge in inches. In the normal series, the long edge is the length of the short edge plus 2 inches (10 in or less) or 3 inches (11 in and above).
Image sensor noise can be compared across formats for a given fixed photon flux per pixel area (the P in the formulas); this analysis is useful for a fixed number of pixels with pixel area proportional to sensor area, and fixed absolute aperture diameter for a fixed imaging situation in terms of depth of field, diffraction limit at the subject ...
Common screen dimensions are listed in the table below (the most common diagonal dimensions in inches as of 2020 are bolded). If the display is not listed, then the following equations can be used. Note that D is the diagonal (in centimeters or inches), W is the width (in pixels), and H is the height (in pixels).
Common aspect ratios used in film and display images. The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1. [1] Two common videographic aspect ratios are 4:3 (1. 3:1), [a] the universal video format of the 20th century, and 16:9 (1. 7:1), universal for high-definition television and European digital television.
The so-called NTSC-Film standard has a digital standard resolution of 720 × 480 pixel for DVD-Videos, 480 × 480 pixel for Super Video CDs (SVCD, Aspect Ratio: 4:3) and 352 × 240 pixel for Video CDs (VCD). [9] The digital video (DV) camcorder format that is equivalent to NTSC is 720 × 480 pixels. [10]
The Ricoh GXR is a compact digital camera first announced by Ricoh Company, Ltd, Tokyo on November 10, 2009. [1] Unlike conventional cameras which either have a fixed lens and sensor or interchangeable lens and a fixed sensor, the GXR takes interchangeable units, each housing a lens, sensor and image processing engine, sometimes called a lensor (a portmanteau of lens and sensor).
The usual size of the sensor is 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm, giving a diagonal of 21.64 mm. [17] [18] The sensor's area is about 30–40% smaller than APS-C sensors used in most other DSLRs, but still around 9 times larger than the 1/2.5" sensors typically used in compact digital cameras.
