...Conceptos de señales de video relacionados con el ojo humano El ojo humano posee 2 tipos de sensores: - Conos (sensores de color) - Bastones (sensores de luminancia) Se le llama cuadro a la imagen que resulta después de la exploración de todas las líneas en que se ha dividido una imagen (imagen completa). Se le llama campo a una exploración completa de la pantalla (medias imágenes). Acuidad – capacidad del ojo en distinguir 2 líneas consecutivas. Típicamente α ” 1 minuto. Siendo D la distancia al ojo y H la altura de la pantalla, se toma generalmente [pic]. Cantidad de líneas horizontales: [pic] ” 572 líneas. La acuidad del ojo es cuadrada, pero como la cantidad de líneas verticales influye en el BW de la señal, se define la pantalla con una relación 4:3. [pic] ” 761 líneas. Persistencia – propiedad de que la imagen quede retenida en el ojo durante un corto espacio de tiempo, por lo cual se debe decidir cuantas imágenes enviar por segundo para dar la idea de movimiento y no molestar al ojo humano con el parpadeo al cambiarlas. Como el ojo retiene cada imagen por 0.1 segundos entonces 10 imágenes por segundo dan la idea de movimiento. Flickeo – depende de la luminosidad de la imagen y de la luz ambiente. La cantidad de flickeos debe ser mayor para no molestar al ojo. En cinematografía se toman 24 imágenes/seg. y se manda repetida la misma imagen (se ahorra cinta), por lo cual se toman 48 imágenes/seg. En TV, cada vez que cambia el cuadro...

...Image Dithering Image and its parameters An image is a two-dimensional representation of a rectilinear array of pixels. A pixel is sample point in the image that has coordinates location it. These samples are obtained from the continuous function CCD cells in a camera, photoreceptors in the eye and rays in a virtual camera. There are three types of image resolution. The first resolution is where each pixel has only the depth bits for color or intensities. The second type of resolution is the spatial resolution which involves the width and the heights of the image only. Lastly, another image resolution is the temporal resolution, and this kind does the monitoring of the image brightness at a particular frequency only. Image dithering Dithering is the approximation of color from a mixture of several colors by the computer program when the desired color is not available. An example if dithering is the when a certain color in the Web page for a particular browser is not supported by the other. In that case, the browser will attempt to replace the desired color by approximating two colors that it can generate. The same may or may not be accepted by the designer of graphics and may appear grainy because it is composed of varied pixel intensities instead of one intensity. Dithering has applications in color image output and for artistic purposes as well. Secondly, dithering is used in web design for reducing images from high color counts to low color counts. It is also used in...

...are graphics composed of small colored squares called pixels, which combine like the tiles of a mosaic to create an image. Examples of bitmap graphics include photographs, scanned images, and graphics created from paint programs. They are sometimes referred to as raster images. Macromedia Fireworks 8 combines the functionality of photo-editing, vector-drawing, and painting applications. You can create bitmap images by drawing and painting with bitmap tools, by converting vector objects to bitmap images, or by opening or importing images. Fireworks has a powerful set of Live Filters for tone and color adjustment, as well as a number of ways to retouch your bitmap images, including cropping, feathering, and duplicating or cloning images. In addition, Fireworks has a set of image-retouching tools—Blur, Sharpen, Dodge, Burn, and Smudge.T The Bitmap section of the Tools panel contains bitmap selection and editing tools. To edit the pixels of a bitmap in your document, you can select a tool from the Bitmap section. Unlike in previous versions of Fireworks, you do not need to deliberately switch between bitmap mode and vector mode, but you can still work with bitmaps, vector objects, and text. Switching to the appropriate mode is as simple as selecting a vector or bitmap tool from the Tools panel. You can create bitmap graphics by using the Fireworks bitmap drawing and painting tools, by cutting or copying and pasting pixel selections, or by converting a vector image into a...

...The purpose of this paper is to critique the user manual of the Samsung 460DX-3 LCD display. The manual is set up in PDF form to easily be viewed on a computer or hand held device. There are numerous tabs to select that will allow the user to quickly find the information they are looking for. The manual seems to be in good written order with images and warnings to help the user operate the display. The first section of the manual is about safety instructions. This section includes both headers and footers to let the user know what subject they are reading about and also what page they are on. The images that are shown are really helpful in determining what may be dangerous to the user while operating the display. The manual uses the color red to show warnings and other images about the display such as the electrical plug and safe lifting instructions. The safety instructions are not vague in any way that would confuse the user. Anyone with the ability to read would be able to understand these safety instructions. The next section of the Samsung’s manual is the introduction section. This section explains to the user everything they must expect when they first get the display home. It shows how to take it out of the box safely and what contents should be in the package when first opening it. This section also includes headers and footers for the user. This section is very useful as it explains the different buttons and inputs that are located on the display. Images are present...

...figure out what they want and what works best for them. Although, consumers are expecting a TV to do more than a modern TV, while it replaces a computer and becomes everything. 2. If I were the manager of a TV place, I would definitely tweak the TV setting to the best picture quality so the customers know the potential the TV has, but I would let them know it’s not standard. My decision would allow customers to know that the TV has potential and they would appreciate my honesty. 3. Because the typical viewing distance is different, depending on each device's use, the pixels per inch claimed to be of Retina quality can differ, depending on the size of the display, with higher PPI for smaller displays and lower PPI for larger displays. Retina display have a pixel density that is so high, your eyes can't discern individual pixels at a normal viewing distance. The Retina display packs four times the pixels of the standard display, giving content incredible detail and dramatically improving the viewing experience....

...Frank Williams 04/05/2015 Ms. Easterling NT1110 In the video, it talked about the different ports on a computer. The Serial port transmits data one bit at a time. It usually is a male port with 9 or 25 pins. The Parallel port transmits data 8 bits at a time. It is usually a female port with 25 pins. The game port is usually female with 15 pins and two rows. The mouse and keyboard ports are used to access the mouse and keyboard. On older computers the mouse and keyboard used PS/2 connectors. All the ports have been replaced by USB ports. There are two types of USB ports, the USB1 which is 56 kbps and cord length of 3 meters. The USB2 which is 480 mbps and cord length of 5 meters. The USB can control up to 127 devices. The NIC (Network Interface Card) is responsible for connecting computer to the Internet. The VGA, DVI, S-video all are used to connect video. There are two types of monitors, the CRT monitor and the LCD monitor. The CRT (Cathode Ray Tube) monitor is usually big and bulky. The LCD (Liquid Crystal Display) monitors are thin and use TFT (Thin Film transistors). The Standard Resolution is 640 x 480, 800 x 600, 1024 x 768. The Native Resolutions are XGA – 1024x768, SXGA – 1280x1024, UXGA – 1600x1200, and WUXGA – 1920x1200.

...In the summary of the topics that the three videos that we’ve watched, we have been taught many things. Instruction of many of the computer’s components and operations have also been reviewed, as well as review of the maintenance of the computers. In the videos, we’ve learned of the interrupt request which is a communication channel from hardware device to CPU, causing the CPU to switch priorities from one task to anther during work. The I/O address wherein the CPU uses a particular address to send instructions to device and the device listens for the address as well as the communication between CPU and the hardware. The memory address, where each hardware device is assigned its own memory addresses and the CPU stores instructions in the memory. Also, we’ve learned of Direct Memory Access where it allows direct communication channel between the device and the system memory that does not require the CPU and makes for faster communication speeds and use of the device manager, used to troubleshoot hardware and resolve resource conflicts in the system. We have also learned of the two main types of monitors on the market today, the Cathode Ray Tube monitor and the Liquid Crystal Display monitor. Liquid Crystal monitors use thin film transistors, also known as an active matrix to display images on the screen, whereas Cathode Ray monitors use tube as high electrical charges to display the images. LCD’s are designed to support a fixed resolution, called a native resolution they...

R.O2, Ogbuokebe S.K3 1,2 Department of Electronic & Computer Engineering, University of Port Harcourt, Rivers State, Nigeria 3 National Space Research and Development agency, Abuja As a result of these, majority of the farmers end up bankrupt while some incur huge debt from banks, relatives or committee of friends in the process [3]. With the proposed drying system, farmers would be able to dry their farm produce using appropriate temperature and humidity control system. Abstract— this paper presents the design and implementation of a microcontroller based Seed Dryer Machine for farm produce interfaced with PC. Drying of farm produce and seeds in large quantity such as; melon, beans, corn, cocoa seeds, pumpkin seeds, rice, pepper seeds, tomato seeds etc., has been very challenging due to lack of drying facilities, drying space and poor weather. This gives low lifespan to the seeds and reduced quantity of stored seeds, which in turn could discourage farmers from further cultivations. In view of this problem, a microcontroller based Seed Dryer Machine is designed to aid and encourage farmers to dry in large scale different farm...
