document describes the features and functionality of a CMOS chipset, comprising an STMicroelectronics (ST) CIF or VGA resolution sensor and an STV0680B companion processor (DCA1), as well as outlining what peripheral components are required/supported in order to complete a camera using the chipset. Such a camera is particularly suited to dual-mode digital stills or toy applications. In stills mode, the camera stores raw image data in memory. The camera carries out no colour processing, ensuring its simplicity and low cost. Subsequent download of raw data to a PC or Macintosh for processing is done through an RS232 or USB interface, through demo software, a TWAIN driver, or OEM custom application. The license to use the colour algorithm (embedded in the PC or Mac driver software) is included in the price of the chipset. A video option is provided, when tethered through USB, which can allow for Video for Windows applications, and ‘video clips’ can be recorded while untethered by continuously capturing images while in ‘Continuous’ mode, then downloaded to the PC for playback, using software to create an AVI file. Using STV0680B-003, the firmware also includes the capability to trigger a flashgun module through a two wire interface (enable input and trigger output), and the capability to record audio sounds into the SDRAM, for subsequent upload to the PC, or to replay audio sounds which have either been recorded on the camera or dowloaded from the PC (stored on the PC as.WAV files). Precise design guidelines are available from ST as a reference design (see Section 4). A software development kit (SDK) for PC is available from ST, to interface to the camera and provide the basis for developing a custom software application for stills and/or video, which includes colour processing software as object code.

Camera can be configured by the user to play custom sounds at certain functions, using a PC application. “Go to sleep” function, whereby the camera can be put into standby mode while untethered. q q q 1.4.5 User features on PC software (STV0680B-001) PC software allows a number of features, including fast download of thumbnail images for picture selection, and automatic detection and correction of sensor defects. The driver compatibility includes: q q TWAIN driver to suit all TWAIN compatible imaging applications Video for Windows PC driver for tethered video mode (through USB), available at all resolutions, with fastest framerates at QCIF resolution AVI video file creation from image sequences captured in ‘continuous’ mode Quicktime Video driver and Adobe Photoshop stills plug-in for Mac q q Custom OEM PC software can be developed by using the SDK (for SDK availability, contact ST), to upload thumbnails/still images or ‘continuous’ images, e.g. for AVI file creation. 8/63 Version 3.4 STV0680B + VV6444/6410/6500 1.4.6 User features on PC software (STV0680B-003) Introduction All PC software written for a STV0680B-001 camera will function with a STV0680B-003 camera which is only used to take still images/video. The SDK (version 2.90 or later) allows for: q the OEM to write a custom application for uploading sound memos, based on the example LCDC demo software. the OEM to write a custom application for downloading custom sounds to the camera, based on the example CustomSound software. q 1.4.7 Power management features and USB compliance q Retention of pictures, recorded sounds, and downloaded custom sounds with extremely low power operation, which appears to the user as if the camera is “switched off”. Auto power-off after 30sec with no user activity Operates from 4.5-6V battery, although system voltage is 5V or 3.3V, dependant on sensor. Low battery detection Dependant on hardware configuration, switch-over to USB power supply is supported, to allow the device to operate with low batteries or without batteries, when connected to USB. Full USB compliance requirements are listed in the USB specification, however, in a camera designed using this chipset, the following must at least be included: (a) an SDRAM with sufficiently low self-refresh current, (b) USB inrush protection circuitry, and (c) (in the case of VV6444 only) a switched 5V sensor supply is used, to maintain sufficient supply voltage to the 5V sensor. See Section 4 for further details. q q q q q 1.4.8 General features q q q High speed picture/sounds upload to PC/Mac over USB ST Colour processing algorithms included under license (as part of drivers/SDK) USB or RS232 serial interface options, and VfW / TWAIN driver support. Version 3.4 9/63 Detailed features STV0680B + VV6444/6410/6500 2 2.1 Detailed features Sensor type and image formats The sensor type is auto-detected by STV0680B, which ensures that the correct sensor timing is enabled, and the correct image resolutions are enabled, as shown in Table 3. For stills photography, ‘High’ or ‘Low’ resolution mode can be selected, to give CIF or QCIF pictures from a CIF sensor, and VGA or QVGA from a VGA sensor (see Table 3). Reduced resolution allows for storage of more images. Images captured in both ‘High’ and ‘Low’ resolution can be stored in camera memory at the same time. Therefore there is no need for images stored in memory to be cleared before changing image resolution. Where USB is connected, the host PC software (through a Video for Windows driver) can activate tethered video mode, regardless of the user inputs to the camera buttons. In this case, the image resolution is controlled by the PC driver. Note: When tethered VfW video (PC) or Quicktime driver (Mac) is activated, all images or recorded sounds or video clips will be deleted from the camera SDRAM. A software solution is available (“Camera control”, as part of the SDK for PC, and “Plug’n Save” for Mac) which can monitor whether a camera is connected and will warn the user if activating the VfW driver will cause SDRAM contents to be deleted.

The reduction of capacity depends on the length of audio clip, but a rough guide is that if 1 CIF image uses the same amount of SDRAM as 10sec of audio, and one VGA image uses the same amount of SDRAM as 30 sec. of audio. 10/63 Version 3.4 STV0680B + VV6444/6410/6500 Detailed features 3 A CIF camera with STV0680B-001 and 64Mbit SDRAM can store up to 320 images by using QCIF mode.

Two memory types have been suggested in Table 18, based on limited evaluation by ST, however this does not constitute a full characterisation, and no guarantees can be made that the self-refresh current consumption will match the target for USB suspend mode in all cases.

Both evaluation kits (STV-DCA/CIF-E04 and STV-DCA/VGA-E04) now include audio record and playback circuitry as well as flashgun interface circuitry and a flashgun hotshoe connector (to allow the OEM to use a standard camera flashgun), allowing the new features as well as the existing features to be demonstrated. Also included are a STV0680B + CMOS sensor chipset, memory, lens, connectors, LCD, battery holder, push buttons/switches, and other components as detailed. Optional PCB links enable alternate functionality, and demonstration software is included, allowing for tethered video, upload to the PC of pictures, sounds, and AVI movie clips, and download to the camera of custom sounds. A reference design manual is available, giving the camera designer everything required to design a complete camera with standard features. It includes schematics, explanatory notes, parts list and layout advice. Audio and flashgun hardware are the subject of separate applications notes, contact ST for details. 12.1 Ordering details Description 36pin LCC, CIF CMOS sensor VV6411C036 48pin LCC, VGA CMOS sensor Standard features STV0680B companion processor Evaluation Kit for STV0680B+VV6410 Evaluation Kit for STV0680B+VV6500 “Standard” + “New” features: Including Audio, Custom sounds, and Flashgun STV0680B companion processor Evaluation Kit for STV0680B+VV6410 Evaluation Kit for STV0680B+VV6500 STV0680B-003 STV-DCA/CIF-E04 STV-DCA/VGA-E04 STV0680B-001 STV-DCA/CIF-E01 STV-DCA/VGA-E01 VV6500C001 Part number VV6410C036 Table 23 : Ordering details for the STV0680B + VV6410/6411/6500 Version 3.4 61/63 Evaluation Kit and Reference design manual STV0680B + VV6410/6411/6500 12.2 Technical support Technical support information, such as datasheets, software downloads,etc, for products of the STMicroelectronics Imaging Division can be found at http://www.vvl.co.uk/ or www.st.com (click on Imaging products) General sales/technical enquiries can be directed to regional email contacts: asiapacific.imaging@st.com centraleurope.imaging@st.com france.imaging@st.com japan.imaging@st.com nordic.imaging@st.com southerneurope.imaging@st.com ukeire.imaging@st.com usa.imaging@st.com 62/63 Version 3.4 STV0680B + VV6410/6411/6500 Information furnished is believed to be accurate and reliable.
