Problems solved by technology

[0006] While currently known and used mechanisms for keeping time in electronic devices are satisfactory, the inventors have found that disadvantages arise when default settings are used with captured images after an extended power loss
On this note, when the real time clock is reset, the chronological order in which the images are sorted will be inaccurate if the images and their associated recording times use the original date of manufacture as the default time
[0007] Secondly, it is not always desirable to use other stand-alone devices as plugging in a second device may limit how the digital camera can be used and the date / time settings of the second device may also be incorrect

Embodiment Construction

[0017] refer to figure 1 A block diagram of an exemplary digital camera 10 according to a preferred embodiment of the present invention is shown. Such as figure 1 As shown, a digital camera 10 includes a lens 12 that directs image light from a subject (not shown) through an aperture / shutter controller 13 on an image sensor 14 having discrete The number of photosensitive points, or pixels, to form individual photosensitive points that correspond to the pixels of an image. Image sensor 14 may be a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) imager, both of which are well known in the art. The photosensitive points of image sensor 14 collect charge in response to incident light. Each photosensitive spot is covered with a color filter array (CFA), such as the Bayer CFA described in commonly assigned US Patent No. 3,971,065. Bayer CFA has 50% green pixels in a checkered pattern, with the remaining pixels alternating between red and blu...

Abstract

A digital camera includes a clock for keeping time; memory for receiving and storing time updates; and a processor for directing the time updates to be recorded in the memory upon occurrence of any of a plurality of camera operations; wherein a default time for the clock is dynamically updated as the time of the last recorded time in the memory.

Description

technical field [0001] The present invention relates to a digital camera having a real-time clock, and more particularly, to a digital camera having a real-time clock with a default setting. Background technique [0002] Currently, digital cameras include a real-time clock to allow various timing functions to be performed. For example, record the date and time the images were captured and associate that date and time with each captured image. This can be achieved by storing date / time metadata in the image file. For example, the well-known Exif image file format includes a creation time stamp that can be used to store the date and time each image was captured. To display captured images in chronological order, or to retrieve images captured on a specific date or during a specific time period, the creation time stamp can be read by various computer software photo applications such as Kodak EasyShare software. [0003] However, after the extended power loss, the real-time cl...
