typedef struct _RCIMG_HEADER

 

{

// size of this header

unsigned long nSize;

unsigned long nPages;

// number of pages/frames

unsigned long nWidth;

// image height

Members

nSize: size of the structure in bytes. It should be 84.

nPages: number of images contained in the file

nWidth: width of each image in pixels.

nHeight: height of each image in pixels.

nBPP: number of bits per pixels (8, 10 or12)

userData: an array of 64 unsigned long that may be user by the user to store other information.

8.1.9.3. Data arrays

The image header is followed by the images data. Images are stored contiguously in compressed format. The first four bytes contains the size of the compressed buffer, followed by image data.

Data compression is done using ZLIB library version 1.1.4, which is free and available for download at the URL http://www.zlib.org.

The compression algorithm used by ZLIB is a variation of LZ77 (Lempel-Ziv 1977). It finds duplicated strings in the input data. The second occurrence of a string is replaced by a pointer to the previous string, in the form of a pair (distance, length). Distances are limited to 32K bytes, and lengths are limited to 258 bytes. When a string does not occur anywhere in the previous 32K bytes, it is emitted as a sequence of literal bytes.

8.1.10.Note on 16 bit grayscale formats

10-bit images acquired from the camera may be saved in different 16 bit formats. These formats include TIF, PNG, MPT, MRF and MCF. Since 16 bit grayscale format is not a standard, not all the applications for image processing may correctly display the saved images.

DIGITAL CAMERA specifications

Sharp has long been a name associated with high-quality electronics, and its foray into the digital camera market showcases the company's commitment to innovation and excellence. The Sharp Digital Camera is designed to cater to both amateur photographers and seasoned professionals, combining user-friendly interfaces with advanced imaging technologies.

One of the standout features of Sharp's digital camera is its high-resolution sensor. Many models are equipped with sensors exceeding 20 megapixels, allowing for stunning detail and clarity in images. This high resolution is complemented by Sharp's proprietary image processing technology, which enhances color accuracy, contrast, and overall image quality. The result is vibrant photos that truly capture the essence of the moment.

In terms of optics, Sharp digital cameras often incorporate high-quality lenses with fast apertures. This enables photographers to shoot in various lighting conditions, from bright daylight to low-light environments. The cameras' optical zoom capabilities allow users to capture distant subjects without sacrificing clarity, making them ideal for landscape photography and wildlife shots.

Another notable characteristic of Sharp digital cameras is their advanced autofocus systems. Utilizing phase detection and contrast detection technologies, these cameras can quickly and accurately focus on subjects, ensuring that even fast-moving scenes are captured with precision. The inclusion of face detection and tracking enhances user experience, making it easier to take stunning portraits.

For video enthusiasts, Sharp digital cameras also offer impressive video recording capabilities. Many models support 4K video recording, which ensures that footage is both detailed and immersive. Features such as image stabilization help reduce shake, allowing for smooth video capture even in dynamic situations.

The user-friendly interface of Sharp cameras is another key selling point. Touchscreen controls and intuitive layouts make navigating through settings simple, even for those who may not be tech-savvy. Additionally, built-in Wi-Fi and Bluetooth connectivity enable seamless sharing of images and videos to mobile devices and social media platforms.

Durability is also a consideration in Sharp's design. Many models feature weather sealing that protects against dust and moisture, which is essential for outdoor photography. This rugged build is complemented by compact and lightweight designs, allowing for easy portability.

In summary, Sharp digital cameras are a blend of advanced imaging technology, excellent optical performance, and user-friendly features. Whether capturing breathtaking nature scenes or precious family moments, these cameras present an exceptional option for anyone looking to elevate their photography experience. With their emphasis on quality and innovation, Sharp continues to make a mark in the digital camera landscape.
