Embodiment Construction

[0032] In order to shorten the time from pressing the power button to taking pictures of the image acquisition device, the present invention aims at the memory card information required for the next startup when the image acquisition device is turned off, especially acquiring information that is time-consuming or requires a lot of calculations. Pre-stored in the internal storage device (internalstorage). At the next startup, the memory card information is directly read from the internal storage device, so the time required for the image acquisition device to calculate the remaining space and perform file sorting can be saved.

[0033] figure 1 It is a block diagram of an image acquisition device according to an embodiment of the invention. Please refer to figure 1 The image capturing device 100 of this embodiment is, for example, a digital camera, or an electronic device with image capturing function, such as a mobile phone, a personal digital assistant, or a notebook computer. ...

Abstract

The invention discloses an image acquiring device and a starting method thereof. The method includes: reading inserting-pulling information of a memory card when a starting signal is received to judge whether the memory card is removed or not when the image acquiring device is powered off; if the memory card is not removed, directly reading free space and a file index table pre-recorded in the memory card to start the image acquiring device; otherwise, if the memory card is removed, recalculating the free space of the memory card, and performing file sorting to generate the file index table so as to start the image acquiring device.

Description

Technical field [0001] The invention relates to an image acquisition device and a startup method thereof, in particular to an image acquisition device and a startup method thereof that can shorten the startup time. Background technique [0002] With the advancement of digital technology, traditional cameras that use film to record images have gradually been replaced by digital cameras that use digital media such as memory cards to record images. Today, the size of digital cameras is getting smaller and smaller so that users can carry them with them. On the other hand, the capacity of the memory card used in digital cameras is getting bigger and bigger, and can record a larger number of images, enough to allow users to fully record every moment of events in various shooting situations. [0003] However, the reality is that many events happen quite suddenly, and the user picks up the camera to take pictures that are fleeting, and in order to capture the wonderful moments, the boot s...
