Zajem in prenos video slike

KOGOVŠEK, TOMAŽ (author), Tuma, Tadej (mentor)

Diplomska naloga obsega predstavitev delovanja in zasnove mikrokrmilniškega gonilnika za kamerni modul OV7670 ter programa za zajem, prenos, prikaz in shranjevanje slike SerialDisplayImage na osebnem računalniku. V prvem delu je obravnavana uporabljena strojna oprema, ki vključuje senzor OV7670 z dodanim pomnilnikom FIFO AL422B, razvojno ploščo STM32F4 Discovery in USB-UART pretvonikom FT232R. V drugem delu pa je predstavljena programska oprema, in sicer funkcionalnost in delovanje gonilnika, ki upravlja s kamernim modulom, ter program na osebnem računalniku, ki služi kot uporabniški vmesnik.

Abstract

This thesis consists of a comprehensive overview on the intricacies and design of a microcontroller based device driver for the OV7670 camera module and the accompanying program SerialImageDisplay for capturing, transmission, display and storing of an image on a personal computer. The first section describes all the hardware components used in the project, which includes the OV7670 sensor with the added AL422B FIFO memory, the STM32F4 Discovery microprocessor development board and the FT232R based USB-UART converter. The second section covers all of the software consisting of the design and functionality of the camera module driver and the computer program, which serves as the user interface.
