Description

This lecture focuses on the analysis of energy consumption in a CCD camera, specifically an interline transfer CCD. The instructor begins by introducing the structure of the CCD, highlighting the sensitive surface, transmission gate, and readout registers. The energy required for operation is calculated using the formula involving capacitance and voltage. The discussion includes a detailed examination of a 1000x1000 pixel matrix, representing a one-megapixel camera, with specific capacitance values and a frame rate of 25 images per second. The instructor explains the energy consumption for capturing an image, including the sensitive surface and transfer gate. The consumption for vertical and output registers is also analyzed, emphasizing the differences in energy requirements based on the CCD's three-phase system. The total energy consumption for one image is calculated, leading to a discussion on power consumption at a rate of 25 frames per second. The lecture concludes with a comparison of CCD and CMOS camera consumption, setting the stage for future discussions.

Charge-coupled device

A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging. In a CCD , pixels are represented by p-doped metal–oxide–semiconductor (MOS) capacitors.

Video camera

A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation.

Image processor

An image processor, also known as an image processing engine, image processing unit (IPU), or image signal processor (ISP), is a type of media processor or specialized digital signal processor (DSP) used for , in digital cameras or other devices. Image processors often employ parallel computing even with SIMD or MIMD technologies to increase speed and efficiency. The processing engine can perform a range of tasks. To increase the system integration on embedded devices, often it is a system on a chip with multi-core processor architecture.

Camera phone

A camera phone is a mobile phone which is able to capture photographs and often record video using one or more built-in digital cameras. It can also send the resulting image wirelessly and conveniently. The first commercial phone with color camera was the Kyocera Visual Phone VP-210, released in Japan in May 1999. Most camera phones are smaller and simpler than the separate digital cameras. In the smartphone era, the steady sales increase of camera phones caused point-and-shoot camera sales to peak about 2010 and decline thereafter.

Professional video camera

A professional video camera (often called a television camera even though its use has spread beyond television) is a high-end device for creating electronic moving images (as opposed to a movie camera, that earlier recorded the images on film). Originally developed for use in television studios or with outside broadcast trucks, they are now also used for music videos, direct-to-video movies (see digital movie camera), corporate and educational videos, wedding videos, among other uses.
