DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
FIG. 1 is a schematic block diagram of a portable composite apparatus according to an exemplary embodiment of the present general inventive concept, and FIG. 2 illustrates a time information table supported in the portable composite apparatus of FIG. 1. Referring to FIGS. 1 and 2, the portable composite apparatus includes a lens block 110, a CCD 120, an image processing unit 130, a GUI unit 140, a storage unit 150, a time information providing unit 160, a control unit 170, an image output unit 180, and an operating unit 190.
The lens block 110 may include by a zoom lens having the ability to vary its focal length to increase or decrease a size of a subject to be photographed, a focus lens to adjust a focus of the subject, and an iris to adjust an amount of light that enters the lens block 100. The lens block 100 receives an optical signal from an external subject.
The CCD 120 transforms the optical signal of the subject which is incident through the lens block 110 into an electronic signal, and outputs the photoelectrically transformed signal.
The image signal processing unit 130 receives an electric signal output from the CCD 120, and removes noises included in the electric input signal, controls a gain to maintain the signal level constant, and converts the signal output from the CCD 120 into a digital signal.
In addition, the image signal processing unit 130 separates the converted digital signal into a luminance signal and a chrominance signal, and performs a predetermined signal processing on the separated luminance signal and chrominance signal, respectively, to thereby adjust a luminance value and a chrominance value of the signals.
The Graphic User Interface (GUI) unit 140 is a means through which a user and the portable composite apparatus 100 interact with each other. The GUI unit 140 generates a GUI corresponding to a user command which is input manually through the operating unit 190, or a GUI corresponding to a user command which is input by selecting an icon or menu displayed on the image output unit 180, and displays the GUI on the image output unit 180.
The storage unit 150 may store a time information table, all programs necessary for an operation of the portable composite apparatus 100, image data from the image signal processing unit 130, etc. The time information table may contain information on photographing modes, a predetermined time range (or span) corresponding to the information on the photographing modes, and predetermined priority levels of the photographing modes. The information on the photographing modes may include at least one of dawn, morning/noon, afternoon, and night, and the time range and the priority levels of the photographing modes can be set up by an operation performed by the user.
The time information providing unit 160 is an internal clock installed inside the portable composite apparatus 100 which can output current time information. The current time information is generated by a clock signal provided by either a real-time clock IC or an oscillator.
The control unit 170 sets the photographing mode in the portable composite apparatus 100 with reference to the current time information received from the time information providing unit 160 and with reference to the time information table stored in the storage unit 150, and determines priority levels of the photographing modes. Accordingly, the control unit 170 may include a decision unit 171 and an operation control unit 173.
The decision unit 171 decides, while referring to the time information table stored in the storage unit 150, whether the current time information received from the time information providing unit 160 is included in the time range corresponding to a current photographing mode of the portable composite apparatus 100, and outputs the decision result.
If the decision unit 171 decides that the current time information was not included in the time range corresponding to the current photographing mode, the decision unit 171 then decides whether the current photographing mode is a basic mode and outputs the decision result. The basic mode may include at least one of an auto mode and a manual mode. In auto mode the user is not able to control parameter values to use when photographing, while in manual mode the user is able to control certain parameters such as flash, sensitivity, white balance, etc.
If the decision unit 171 decides that the current time information was included in the time range corresponding to the current photographing mode, the operation control unit 173 controls both the current photographing mode of the portable composite apparatus 100 and the priority levels corresponding to the photographing modes therein.
Moreover, if the decision unit 171 decides that the current time information was not included in the time range corresponding to the current photographing mode and that the current photographing mode was set to the basic mode, the operation control unit 173 controls the current photographing mode of the portable composite apparatus 100 to be the basic mode without any change. Also, the operation control unit 173 refers to the time information table to control the priority level of the current photographing mode to be changed to the priority level of the photographing mode corresponding to the time range that includes the current time information. That is to say, the operation control unit 173 changes a sequence of the photographing modes provided from the first to the last photographing mode in the menu to set the photographing mode, and controls the GUI unit 140 to output this change to the image output unit 180.
Further, if the decision unit 171 decides that the current time information was not included in the time range corresponding to the current photographing mode and that the current photographing mode was not set to the basic mode, the operation control unit 173 controls the current photographing mode of the portable composite apparatus 100 to be changed to the basic mode. Also, the operation control unit 173 refers to the time information table again to control the priority level of the current photographing mode of the portable composite apparatus 100 to be changed to the priority level of the photographing mode corresponding to the time range that includes the current time information.
At this time, if the priority level of the photographing mode has changed, the operation control unit 173 controls the GUI unit 140 to output a message and/or an icon to notify the user of the change in the photographing mode information in the image output unit 180. That is, when the priority level of the photographing mode has changed, the operation control unit 173 controls the GUI unit 140 to notify the user that the photographing mode information corresponding to the photographing mode priority level has been changed.
FIG. 3 is a flow chart illustrating how the portable composite apparatus of FIG. 1 operates.
By referring to the time information table stored in the storage unit 150, the decision unit 171 can decide whether the current time information received from the time information providing unit 160 is included in the time range corresponding to the current photographing mode of the portable composite apparatus 100 in equation S310. If it is decided in the decision unit 171 that the current time information received from the time information providing unit 160 was included in the time range corresponding to the current photographing mode of the portable composite apparatus 100 (i.e., in operation S310:Y), the operation control unit 173 controls the current photographing mode of the portable composite apparatus 100 and the priority levels of photographing modes therein to be used as they are.
If the decision unit 171 decides that the current time information was not included in the time range corresponding to the current photographing mode (i.e., operation S310:N), the decision unit 171 decides whether the current photographing mode was set to the basic mode in operation S320. If the current photographing mode was indeed set to the basic mode, the operation control unit 173 controls the current photographing mode of the portable composite apparatus 100 to be the basic mode without any change, and controls, by referring to the time information table, the priority level of the current photographing mode to be changed to the priority level of the photographing mode corresponding to the time range that includes the current time information.
The basic mode may include at least one of an auto mode and a manual mode. In the auto mode, the user is not able to control parameter values to use during photographing. In the manual mode, the user is able to control certain parameters such as flash, sensitivity, white balance, etc.
If it is decided in the decision unit 171 that the current photographing mode has not been set to the basic mode (i.e., operation S320:N), the operation control unit 173 controls the current photographing mode of the portable composite apparatus 100 to be changed to the basic mode in operation S330.
By referring to the time information table again, the operation control unit 173 can control the priority level of the current photographing mode of the portable composite apparatus 100 to be changed to the priority level of the photographing mode corresponding to the time range that includes the current time information in operation S340. In other words, the operation control unit 173 sequences, based on the current time information, the photographing modes to be placed on the first to the last of a photographing mode setting menu to thereby change priority levels of photographing modes of the portable composite apparatus 100, and changes the sequence of changing icons of photographing modes to the sequence of the priority levels of photographing modes through an operation of shortcut buttons while shooting.
Referring to FIG. 2, if the photographing mode information of the portable composite apparatus 100 in power-off mode is “Night,” the current photographing mode is set to “Night,” and then the photographing mode information corresponding to the time range that includes the current time information in power-on mode is “Afternoon.” Since the current photographing mode is “Night,” which is not the basic mode, the operation control unit 173 changes the current photographing mode to the basic mode, and changes the priority level of the photographing mode from the priority level corresponding to the “Night” photographing mode to the priority level corresponding to the “Afternoon” photographing mode.
Namely, the operation control unit 173 sequences photographing modes output to the photographing mode setting menu from “Auto,” “Manual,” “Night,” “Fireworks” . . . to “Auto,” “Manual,” “Dawn,” “Portrait” . . . . At this time, the operation control unit 173 also changes the toggle sequence of icons corresponding to the photographing mode that is output to a screen being photographed from priority levels corresponding to the “Night” photographing mode to priority levels corresponding to the “Afternoon” photographing mode.
The operation control unit 173 notifies the change in the priority level of photographing modes to the user by outputting a message and/or icon indicating a change in the priority level in operation S350. When the photographing mode information corresponding to the time range that includes the current time information is “Afternoon,” the operation control unit 173 controls the GUI unit 140 to output to the image output unit 180 at least one of message and icon notifying that the photographing mode information has changed from “Dawn” to “Afternoon,” to thereby notify the change in photographing mode information to the user.
In the portable composite apparatus and the method of controlling photographing modes according to an embodiment of the present general inventive concept, the time information providing unit 160 may be installed separately from the control unit 170 or installed inside the control unit 170.
Moreover, in the portable composite apparatus and the method of controlling photographing modes according to an embodiment of the present general inventive concept, the decision unit 171 not only decides by referring to the time information table stored in the storage unit 150 whether the time range corresponding to the current photographing mode of the portable composite apparatus 100 includes the current time information, but also decides whether the photographing mode information corresponding to the time range that includes the current time information coincides with the current photographing mode of the portable composite apparatus 100, and outputs its decision results. Accordingly, the operation control unit 173 sets the current photographing mode of the portable composite apparatus 100 and the priority levels of photographing modes based on the decision results provided from the decision unit 171.
As described above, according to the embodiments of the present general inventive concept, photographing modes of a portable composite apparatus may be prioritized differently based on current time information and the time information table, to thereby enhance user convenience and expedition of operating (or setting) a desired photographing mode.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
