Description

M255425 Description of creation (1) The new technical field belongs to Yiji α ^ is a chroma detection box that can be used for camera production, especially to avoid the change of the light on the clothes and the convenience of the user. Degree detection box. Dingquan I-fruit is produced by Xiangmen Ye Wanshi Previous technology

Close r: 31? 'La & Ristoldo has found that in a dense g: two I rape', the hole § the light penetrates into this small hole, it will be on the inner wall of the box ^: Ϊ 外The opposite image of the scene. Later, this concept began to have 3 = exhibited a pinhole observation device (Plnhole0bscura), and was actually used to observe the sun.一 古 η 思念 „M / Until the eighteenth century, some people began to replace the wall surface of the subject with light to produce an image, and replaced it with a photosensitive surface, which resulted in the predecessor of modern cameras. The early cameras were also called Pinhole camera (pinhole = e; a 'outside = the object is directly imaged on the film without any lens 1 Ί In general, the clarity of the pinhole camera image is affected by

A ten-hole (Pmhole) aperture size affects, the smaller the aperture, the clearer the imaging. However, as the aperture shrinks, the effect of 婊 ·) on imaging gradually increases. Due to the drastic reduction of ^ machine ^ lf had1011, the light time required for negative film exposure: the amount of light P., and the exposure time corresponding to nine A substantial increase. All of the above have caused pinhole cameras to disappear almost completely from the cameras on the market today, whether they are so-called monocular cameras.

M255425 Fourth, the creation description (2) '~ (Single Lens Ref lex), or the so-called Compact Camera, are designed with a lens to focus the image. At the same time, according to the difference of the photosensitive device, it can be divided into traditional cameras and digital cameras. Traditional cameras use negative film as the medium for imaging the scene. After the photosensitive film is developed and developed, the image is presented in the photo. Digital cameras use electronic components such as Charge Coupled Device (CCD) or complementary metal-oxide

Semiconductor, CMOS), which senses the external light, and then converts the sensed electronic signal into an image building for immediate presentation. However, due to the following reasons, whether it is a traditional camera or a digital camera, there is a problem of the deviation between the imaging and the actual color of the scene: 1. During the focusing process, the lens will absorb and reflect some specific wavelengths of light, resulting in external appearance. The wavelength combination of the light projected by the scene and the lens differs from the wavelength combination of the light projected through the lens and projected on the negative or the photosensitive element. 2. As for the traditional camera, after the negative is exposed, the image must be developed and processed before the image can be displayed on the photo. Therefore, the pros and cons of the light-sensitive material on the negative, and the technology of the development and processing processes will affect the authenticity of the color of the image on the photo. 3. For the digital camera, the light signal is sensed by the light-sensing element, and the light signal is converted into an electric signal, which is then combined into an image file after calculation. Therefore, the process of converting optical signals into electrical signals and the process of calculating electrical signals into image files will have an impact on the authenticity of the imaged colors. Therefore, in order to confirm the deviation of the imaged color from the true color, usually
