A device includes a photographing unit, an image processing unit, a buffer, a storage unit, and a digital signal processor. The buffer stores index information to be assigned to at least one image signal obtained by the photographing unit, file name and storage path information to be provided to the at least one image signal when the at least one image signal is stored in the storage unit. The digital signal processor displays the most recently stored image signal when a display input instruction to display a currently captured image is received, searches the storage unit when an input instruction to display previously-captured images is additionally received, if a corresponding image file is found in the storage unit, displays the found image file, and if the corresponding image file is not found in the storage unit, displays an image signal stored in the buffer using the index information.

Device and method for making quick change to playback mode after photographing subject

Disclosed is a digital video camera performing white balance adjustment according to a photographing condition. The digital video camera with automatic exposure comprises an iris state detector for outputting an electrical signal with a predetermined magnitude corresponding to the status of an iris, a memory for saving a threshold value to be compared with the magnitude of the electrical signal, and a controller for comparing the magnitude of the electrical signal output from the iris state detector with the threshold value, determining the photographing condition after a predetermined determination time is elapsed, and adjusting the determination time according to the difference between the magnitude of the electrical signal and the threshold value.

Digital video camera with automatic white balance and a method thereof

An apparatus and method for a digital image device having an image-capturing device for photoelectrically changing an optical image focused through a lens unit, and for converting a signal output from the image-capturing device into a digital signal and processing input color data which is output in a predetermined period are disclosed. The apparatus and method comprise changing a range of established luminance levels every predetermined period, and luminance-dividing and storing color data, from the input color data, which belongs to the range of the established luminance level; detecting a white color out of the luminance-divided and stored color data, and setting to a range of clip luminance levels a range of luminance levels to which the detected white color belongs. The apparatus and method also comprise dividing an image captured on the image-capturing device into the predetermined number of windows, and view-dividing and storing color data in the window which belongs to the range of clip luminance levels with changing the windows every predetermined period. The apparatus and method further comprise calculating a final white color value based on the view-divided and stored color data.
