Many technologies are needed, such as semiconductors, optoelectronics, Micro motors and other support.It has been a huge wav

is filled at the rear of an optical lens. When light and image pass through and are projected to the CCD surface from the lens, the CCD will generate current, convert the inductive content into digital data for storage. The larger the number of CCD pixels and the larger the size of a single pixel, the clearer the collected image. Therefore, although the number of CCD is not the only key to determining the

Crop factor)Because the imaging chip in the camera is usually less than 35mm film, it has different characteristics when you place the lens for the SLR camera on the DSLR camera. It seems that the image has been cropped, so there is a cropping coefficient. For example, a 100mm lens will change to a 160mm lens on a camera with a cropping factor of X (for example,

After measuring the MTF value curve of each lens, the Hassu lab developed a calculation method for the average value of the MTF. First, the preset focal length is used to calculate the MTF value of the lens F4, multiply by the focusing coefficient of 0.4 and 0.6 respectively to obtain the MTF value of a first-line frequency, and then multiply the average value of the 10-line/millimeter value by the focusing

animation. 　　 1. Rocking Lens When shaking the lens, it moves from one direction to the other in the scene. It can be shaken from left to right, from right to left, or from top to bottom, or from bottom to top. You can't create this effect directly in flash through the lens, you need to move the elements of the scene in the stage. Qhwa: The following conte

Industrial lens is equivalent to the lens of the human eye, if there is no lens, the person can not see any object, if there is no lens, then the image of the camera output, is a vast expanse of whiteness, there is no clear image output, which is consistent with the principle of our home camera and camera. When the hum

Title Description:Given two ordered arrays of arr1 and arr2, given an integer k, returns the small number of k in all the numbers of the two arrays.For example:arr1 = {1,2,3,4,5};ARR2 = {3,4,5};K = 1;Since 1 is the smallest of all the numbers, it returns 1;ARR1 = {n/a};ARR2 = {3,4,5,6};K = 4;Since 3 is the 4th small number in all numbers, it returns 3;Requirements: If the length of the arr1 is N,ARR2, the time complexity should be O (log (Min{m,n})).1 /*2 idea: Using the last problem Nowclass3-4

Optical zoom: Optical zoom occurs when the positions of the lens, object, and focus change. When the imaging surface is moving horizontally, for example, the visual and focal length will change, and the farther scenes will become clearer, making people feel like objects are moving forward. Therefore, changing the focal length of a lens is optical zoom. An optical zoom multiple is the ratio of the maximum fo

(The Nikon lens with a AF-S and the HSM snap can focus automatically on the d40) With the price reduction of digital SLR, many friends want to buy digital SLR, but many people do not know how to choose a camera, in addition, many merchants and professional media intentionally say some words as "professional" to raise the threshold for SLR ", many "heroes and birds" also love to move out some of Nikon's ox heads and Canon's magic mirrors to "educat

Crawling for a long time, finally found a foreign introduction, said can be replaced by HK-4, better than the HK-7, and can be replaced by 85mm 1.4D-IF Hood HN-31, using a 77mm-> 72mm rotor interface is also very good, and the 77mm filter can also be used together. Then there is the use of HN-9 unscrew Hood can also be,
