Described is an electronic device for performing certain operations and includes a continuous operating unit providing operations benefitting from a backup battery for providing backup power to the continuous operating unit. The battery is installed in the electronic device at the time of manufacture and is connected to the continuous operating unit through a switch which is in the open position at the time of manufacture of the electronic device. An input device allows a user to input signals to the electronic device. A central processing unit is connected to the continuous operating unit and receives the input signals from the input device. The central processing unit contains firmware for performing the operations of the electronic device and the central processing unit closes the switch when a predetermined parameter is received from the input device. A main power source is connected to the central processing unit and the continuous operating unit for providing operating power to the central processing unit and the continuous operating unit. Also described is a method of operating an electronic device including executing an initialization procedure when an on/off control of a electronic device is actuated to an on condition, obtaining input information via an input device, analyzing the input information in a central processing unit to determine if a predetermined parameter is being input for the first time and closing a circuit between a backup battery and a continuous operating unit via a signal from the central processing unit when the predetermined parameter is input for the first time.

A new and improved digital camera includes a zoom in switch and a zoom out switch to effect respective zoom in operations and zoom out operations in both an optical zoom mode of operation and a digital zoom mode of operation. A zoom control arrangement responds to the zoom in switch to decrease a maximum optical zoom factor by one incremental setting when a current digital zoom factor is not equal to a maximum digital zoom factor of about D to facilitate developing a smooth transition to a next incremental optical digital zoom factor setting. The next incremental optical digital zoom factor setting is an individual optical digital zoom factor in a combined optical digital zoom factor range from a minimum optical digital zoom factor product of about Z D to a maximum optical digital zoom factor product of about Z D. The zoom control arrangement further responds to the zoom out switch when the current digital zoom factor is not equal to a minimum digital zoom factor of about D to increase a minimum optical zoom factor of about Z by one incremental setting to facilitate developing a smooth transition to a next lower optical digital zoom factor setting.

A camera which powers up in a default fixed-focus mode and has a capability whereby the photographer can select an auto-focus mode. The camera includes a lens, a shutter and a motor for moving the lens and for opening the shutter. A CCD, electrically interconnected to an analog to digital signal converter, receives image data and transforms the data to analogs for transmission to the converter where a digital output signals is generated. The digital signal is electrically transmitted to a processor which is electrically connected to the motor. In the camera default fixed focus mode, a first control algorithm facilitates a process wherein the processor generates an electrical signal to cause the motor to move the lens directly to a control position. To elect the auto-focus mode of camera operation, the photographer depresses a button and thereby selects a process which functions in accordance with the steps of a second control algorithm wherein the processor generates an electrical signal to cause the motor to move the lens past a focal point, and a second signal to cause the lens to backstep to the focal point. When the auto mode is selected, an icon appears on a data liquid crystal display (LCD) to indicate that auto focus mode is selected.

A digital camera includes a processor having an algorithm for comparing a set of resolution pixel values in a generated image file with corresponding ones of resolution pixel values in a user selected file and for providing as a final digital zoom image resolution the set of resolution pixel values in the generated image file when the corresponding ones of the resolution pixel values in the user selected file are at least equal but not less than the corresponding resolution pixel values in the generated image file, and a scaled down set of resolution pixel values when the corresponding ones of the resolution pixel values in the user selected file are less than the corresponding resolution pixel values in the generated image file.

Files are divided into parts and at least some of the parts are transmitted to a client using a communication channel. At least some of the transmitted parts are cached locally. This allows subsequent streaming playback of the file while using less bandwidth by transmitting the part of the file that hasn't been cached, and combining the cached parts with the transmitted parts. In some embodiments, files may be represented at a low quality level by a first data set, and at higher quality levels with additional data sets. Data sets are cached locally, so that during subsequent streaming playback of the file, the quality level of the playback may be improved by sending additional data sets using bandwidth that would otherwise be dedicated to transmitting the cached data sets.

A multi-level error diffusion system includes a processor that creates an m by n super pixel cell as an output pixel value for individual ones of a plurality of single input pixel values that are indicative of an image. The processor assigns to individual ones of the m by n super pixel cells available printer output color values, where the average of the assigned output values are selected to be as close as possible to corresponding individual one of the single input pixel values. A multi-level printer receives the individual ones of the m by n super pixel cells having assigned output values and converts them into printer data to form a printed image.
