[0070] The first embodiment of the present invention is a camera-equipped portable phone / PHS (Personal Handyphone System) (hereinafter simply referred to as "portable phone" for simplicity of description) including a focus state display device. FIG. 1 shows the appearance of a camera-equipped cellular phone including a focus state display device. FIG. 1(A) shows a rear view of the portable telephone of this embodiment, and FIG. 1(B) shows a front view thereof. Figure 14 A functional block diagram showing an example of the schematic configuration of the portable telephone according to the present embodiment is shown.

[0071] In FIG. 1, a camera-equipped portable telephone 10 includes a body portion 10a and an antenna 111 for radio communication. The back of the body part 10a includes a camera 112 (imaging device) for taking images, an LED (Light Emitting Diode) 113 (light emitting device) for notifying the focus state by blinking or emitting light, and a camera 113 (light em...

[0125] In this embodiment, since the focus state display device and the portable telephone 10 equipped therewith are the same as those in the first embodiment shown in FIGS. 1 and 2, their descriptions are omitted. The first embodiment is constructed so that the focus state is displayed on the display screen on the LCD display section 115 or 116, as Figures 5 to 11 as shown in . In contrast, the second embodiment is characterized in that, instead of displaying on the LCD display section 115 or 116, or in addition to displaying on the LCD display section 115 or 116, by using a predetermined method The LED 113 on the panel blinks or glows to notify the user of the focus status.

[0126] exist figure 2 Among them, for example, as a way to make the aforementioned LED 113 blink in a predetermined way, the focus state display device 31 can be constructed so that it can always calculate a value obtained by dividing a predetermined value by the value of the focus state. , and use ...

Abstract

A focus state display device, comprising: focus area extracting means for extracting an image signal of a predetermined area from the picked up image signal; edge enhancement processing means for enhancing the edge of the extracted image signal; a time accumulation value computing means for calculating the cumulative value of the edge-enhanced image signal over a predetermined period of time; the focusing state judging means for judging whether the picked-up image signal is in the focused state according to the calculated cumulative value; and the focusing state display means for to display the judged focus state. Even when a display device of a mobile terminal device having a built-in camera has a limited size and resolution, a user can easily check and adjust the focus of the camera.

Description

[0001] This application is a divisional application of the patent application with the application number 200480009167.9, the application date is January 16, 2004, and the invention title is "focus state display device and focus state display method". technical field [0002] The present invention relates to an apparatus for displaying a focus state of a camera and a display method thereof, and more particularly to an apparatus for displaying a compact portable camera and a camera-equipped portable terminal device such as a portable phone equipped with an imaging function. A technology that fixes the focus state of a camera. Background technique [0003] In recent years, with the development of image sensors that are small in size and low in power consumption, portable devices with built-in cameras, such as PDAs (Personal Digital Assistants), cellular phones, and portable PCs (Personal Computers), have been widely used. [0004] These portable devices can take images and pri...
