Description

The digital camera device of tool power consumption management and power consumption management system thereof and method

Technical field

A kind of power consumption management is technological, refers in particular to a kind of digital camera device and power consumption management system and method for tool power consumption management.

Background technology

Modern science and technology is fast-developing, and the digitized video technology emerges, and along with the increase of internal memory and hard-disk capacity, the quality of image is exquisiteness more and more, and the aspect of application is also more and more wider, except digital photos, similarly is that various pictures, animation are audio-visual or the like, and is also all complete.

Along with the digitized video technology is ripe gradually, when digital camera device has also become many people's out on tours must with one of outfit.And the electronic product of digital camera device and other portable has the restriction of electric quantity consumption equally; When especially using the recording function of digital camera device; The use amount of electric quantity consumption and internal memory is rapid especially, finds that when wanting to use electric weight is not enough, can let the people feel disappointing really.Existing for avoiding the waste of power supply; Use the mode of setting stand-by time to reduce consumption, do not have use, just automatic powered-down when electronic installation standby a period of time; Do not improve the power supply service efficiency but the method has, just reduce the power supply waste that the user is caused when not using electronic installation.

The power consumption management of existing digital camera device is not that standard-sized sheet is exactly a complete shut-down, the use shortcoming efficient of its power supply.With the digital camera is example, with reference to Figure 1A, is the power consumption management under the exposal model of existing digital camera; The form left refers to the power consumption coefficient of a plurality of electricity consumption modules; From top to bottom be respectively ASIC (Application Specific IntegratedCircuit, ASIC), focusing (Auto Focus, AF), photoflash lamp (Flash), camera lens (Lens), screen (Panel); And charge coupled cell (Charge Coupled Device, CCD).The form top refers to the imaging program of digital camera under the exposal model; By left-to-right; That classifies example as with flash power (WFlash), and the imaging program of digital camera is described, when electric power starting; The power supply of photoflash lamp promptly is supplied (0 → 1, represent the power supply supply to become standard-sized sheet from complete shut-down) and is used for the photoflash lamp that charges; Then digital camera gets into the camera lens opening, continues power supply charging photoflash lamp this moment; Come digital camera to get into screen display state again, still continue power supply charging photoflash lamp this moment; A period of time does not use, and digital camera gets into holding state and waits for that the user takes pictures Flash ready, stop supplies flash generator (1 → 0, represent the power supply supply to become complete shut-down from standard-sized sheet); The user then presses shutter, and digital camera gets into the state of taking pictures, pick-up image; Last digital camera stores the photo image in internal memory, and then the entering holding state waits for that the user takes pictures.Existing exposal model power supply method of supplying is not that complete opening is exactly to close fully, does not consider the electricity consumption weighted value, does not do efficient power supply supply control yet.

Likewise; With reference to Figure 1B, be the power consumption management under the video recording pattern of existing digital camera, the form left refers to the power consumption coefficient of a plurality of electricity consumption modules; From top to bottom be respectively ASIC, focusing, photoflash lamp, camera lens, screen, and charge coupled cell.The form top refers to the imaging program of digital camera under the video recording pattern; By left-to-right; That classifies example as with screen power (WPanel), and the imaging program of digital camera is described, when electric power starting; The power supply of screen promptly is supplied (0 → 1, represent the power supply supply to become standard-sized sheet from complete shut-down) and is used for display frame; Then digital camera gets into the camera lens opening, continues the supply screen power supplies this moment; Come digital camera to get into screen display state again, still continue the supply screen power supplies this moment; A period of time does not use, and digital camera promptly gets into holding state and waits for user's video recording, stop supplies screen power supplies (1 → 0, represent the power supply supply to become complete shut-down from standard-sized sheet); The user then presses video recording, and digital camera is opened camera lens, display screen, supply screen power supplies (0 → 1, represent the power supply supply to become standard-sized sheet from complete shut-down); Digital camera gets into video state, recording image; Last digital camera stores the film file in internal memory, and then gets into holding state wait user video recording, stop supplies screen power supplies (1 → 0, represent the power supply supply to become complete shut-down from standard-sized sheet).Likewise, the power supply method of supplying of existing video recording pattern is not that complete opening is exactly to close fully, does not consider the electricity consumption weighted value, does not do efficient power supply supply control yet.

Therefore, the problem of power consumption control is a problem of being badly in need of improvement in portable electronic product.
