Abstract: A method of controlling a digital camera includes performing photographing of an object, determining whether the amount of exposure is appropriate and shakiness is present, and notifying a user of such information if the amount of exposure is not appropriate or shakiness is present. The determination step includes reading a focus value of the object, reading a lower limit value of a compressed file size set to correspond to the read focus value of the object at a compression rate and a resolution set by the user, and determining that the amount of exposure is not appropriate and shakiness is present if the size of a present compressed file of image data obtained from the photographing is smaller than the lower limit value of the compressed file size.

Abstract: A method of controlling a digital photographing apparatus is provided. The digital photographing apparatus includes a shutter release button having a two-step structure and the digital photographing device performs automatic focusing in a photographing mode according to a setting set by a user. First, a voice command input by the user is recognized when the shutter release button is pressed to a first step according to a manipulation of the user, and automatic focusing of an input location region is performed according the recognized voice command. Then, a photographing operation is performed when the shutter release button is pressed to a second step according to a manipulation of the user.

Abstract: A flash controlling apparatus is provided including a light receiving unit PS, a current-to-voltage converter IVC, a comparator CR, and a micro-controller MC. The light receiving unit PS generates a current signal corresponding to the flash intensity of a camera. The current-to-voltage converter IVC converts the current signal received from the light receiving unit PS into a voltage signal SPS. The comparator CR compares the voltage signal SPS with a reference voltage VREF to obtain a resultant logic signal SCOM. The micro-controller MC controls the operation of the current-to-voltage converter IVC and controls the operation of a flash device of the camera according to the resultant logic signal SCOM received from the comparator CR. The voltage signal SPS from the current-to-voltage converter IVC has the characteristics of a logarithmic function with respect to time.

Abstract: A digital still camera using a progressive image sensor includes an image sensor for capturing images and for generating image signals corresponding to the images, an image processor for generating image data corresponding to the image signals from the image sensor, and a memory for storing the image data from the image processor line by line. The invention further includes an image compression/decompression unit for compressing the image data and for decompressing the compressed image data, and a controller for controlling the image sensor, the image processor, and the image compression/decompression unit. Since the digital still camera uses a progressive image sensor which simultaneously generates analog image signals corresponding to an entire image, frame memories are not necessary for storing images.

Abstract: An improved method and apparatus for monitoring the amount of use sustained by a replaceable part within an electrophotographic printing apparatus is disclosed. In response to a print command, a controller reads data from a permanent memory within the replaceable part. The data, which indicates how much use the replaceable part has sustained, is then stored in a buffer within the controller. The data is then incremented by one for each page printed by the printing apparatus. Once the data equals or exceeds a predetermined use value indicative of the operational lifetime of the replaceable part, a user is informed of this condition through a replacement message.
