DIGITAL CAMERA DESIGN
A digital camera.

A digital camera is a camera that captures photographs in digital memory. However, unlike film cameras, digital cameras can display images on a screen immediately after being recorded, and store and/or delete images from memory.

Program Development

The design/manufacturing process must be well understood at the macro level by the facility planning and engineering team to ensure that an appropriate design concept is developed that is intergrated with manufacturing needs. Hiring a consultant(s) should be considered.

Design Aspects

The primary aspects of digital camera design are: Aperture , Lens , Shutter, Shutter Trigger , Button Interface , Digital LCD Display , Image Sensor, Viewfinder, and Inbuilt Flash. The various design aspects are joined together to form a coherent ergonomic device.

Design Constraints

Expertise with both hardware / software is needed to optimize design metrics for a given application. Flexibility is essential should the need arise to change the functionality of the system without incurring additional non-recurring engineering (NRE) cost.

Design Optimization

Digital camera manufacturing projects require the expertise of research/development personnel to initiate the automation process. Once the process is engaged, the technical aspects of implementation are supervised by different teams comprised of automation / electrical / engineers along with technicians to assure synchronization of the processes.

Computer Designed Camera

Innovative digital camera design(s) and illustration(s) may be achieved using AutoCAD or any commercial computer-aided design and drafting software application. Camera schematics and high-frequency HDI PCB layouts with interdisciplinary coordination with optics / thermal design drawings facilitate transition to the automated production process.

Design Process/Simulation

Through the use of simulation, electrical / mechanical engineers can quantify the effects of individual digital camera components on system performance along with image quality. This analytical / computational approach can be useful to allow engineers to use a spectral image processing algorithm in order to simulate the radiometric properties of a digital camera.

Designing a Digital Camera

A digital camera is a still camera that records images in digital form. Unlike traditional analogue cameras that record infinitely variable intensities of light, digital cameras record discrete numbers for storage on a flash memory card or optical disk. As with all digital devices, there is a fixed, maximum resolution and number of colours that can be represented. Images are transferred to the computer with a USB cable or via the memory card. Digital video cameras also use FireWire.

Digital Advantages: There are two distinct advantages of digital cameras. The first is being able to see the final image right away so you know you have the picture you wanted. Bad pictures can be instantly erased. The second is convenience. You can take one picture and print it without waiting to develop an entire roll of film or wasting the whole roll for just a few pictures. In addition, "digital film" is reusable, except for the write-once optical disc (CD-R) variety.

Chips and Flash: The film in a digital camera is made up of photosensor chips and flash memory. The camera records color images as intensities of red, green and blue, which are stored as variable charges on a CCD or CMOS image sensor chip. The charges, which are actually analogue, are converted to digital and stored in one of several flash memory formats such as CompactFlash or Memory Stick. Instead of memory cards, some still cameras use optical disc for storage, and video cameras may use discs or tape (eg., Digital Video). The size of the chip determines the resolution, but the analogue-to-digital converter(ADC), which converts the charges to digital data, determines the color depth. In 2002, Foveon introduced a breakthrough in color accuracy with its X3 CMOS chip (see Bayer pattern and X3). Digital video cameras also use these same image sensing methods, but may also output traditional analogue signals (NTSC) in addition to digital. See flash memory, photo editor, photo scanner, X3 and Digital single lens reflex (DSLR).

• Resolution in Megapixels: The number of pixels determines the maximum size of a printed photo without sacrificing quality. For 3x5" and 4x6" prints, 2 megapixels is good. For 5x7" and 8x10" prints, 5 megapixels is preferred. For low-resolution images on the Web, almost any digital camera will suffice. However, you can easily reduce a high-quality image to the low resolution required online. The higher the resolution from the start, the better the results.

• Optical Quality: Megapixel resolution is a quantitative measurement, but the lens itself is qualitative. The optical quality of the lens greatly contributes to the resulting picture quality as it has in analog cameras for more than a century. To make a decision on this one, the printed pictures have to be seen.

• Optical vs. Digital (Interpolated) Zoom The optical zoom is the real resolution of the lenses. The digital zoom is an interpolated resolution computed by software. The higher the optical number, the better. A 10x optical is far superior to a 10x digital. Some digital zoom numbers go into the stratosphere, especially for video, but optical is what counts.

•Storage Media: There are several types of flash memory cards used for "digital film," but no matter which type the camera uses, the one that comes with the camera is typically undersized. Plan on purchasing a larger one when you buy the camera (see flash memory).

• Data Transfer: Digital cameras come with a USB cable for transfer directly to the computer, and many computers come with one or more memory card slots. Printers may also come with card slots, allowing you to print your photos without using the computer at all.

• Battery Duration: Digital cameras use either rechargeable or standard AA batteries. It can take an hour or more to recharge a battery, so an extra one, fully charged, is always a good idea to have along. AA batteries can be purchased almost anywhere, and rechargeable AA batteries can also be used.

• Interchangeable Lenses: Digital single lens reflex (DSLR) cameras are the digital counterparts of their analog predecessors and may use the same removable lenses that you already own. However, the chip is often smaller in size than a 35mm frame, which means your 28mm wide angle lens may function like a 42mm lens. Increasingly larger chips and wider angle lenses are solving the problem.

Additional utility considerations are as follows:

Digital cameras are integrated with a wide range of digital devices, ranging from personal digital assistants (PDA) and mobile phones to the Hubble and Webb Space Telescopes.

Digital photography is adaptable and compatible with email, CD/DVD, TV and computer monitors, the Web and may be stored on a personal computer (PC). Some digital cameras have a built-in GPS receiver, which is used to produce geotagged photographs. Digital photography's key advantage is immediate video and image viewability. Image editing software is used for cropping, recoloring, and combining one or more contrast/imperfection adjustment images.

Digital cameras come in an array of sizes, features and prices, including the following: Compact digital camera: Portable, easy to use and small with limited picture quality. Built-in low-power flash. Images are usually stored as JPEG files. Also known as a point-and-shoot camera.•

• Digital single lens reflex camera (DSLR): Design is based on the single lens reflex camera. Exclusive viewing system that uses a mirror to reflect light from the lens via an optical viewfinder.

• Bridge camera: Shares some DSLR advanced features. Uses a fixed lens with a small sensor - similar to compact digital cameras. Uses live preview for image framing.

• Mirrorless interchangeable lens camera (MILC): Combines superior quality sensors with DSLR lenses. Introduced in 2008, the MILC is simple and compact because of its ergonomic design.

• Line scan camera system: Supports focusing mechanisms and usually contains a line scan sensor chip. Used by industrial applications to capture moving material images.
