Embodiment Construction

[0037] Referring now to FIG. 3 , a camera-equipped mobile terminal according to an embodiment of the present invention includes a camera module 51 , an interface 52 , a CPU 53 , a main LC board 54 and a sub-LC board 55 .

[0038] The camera module 51 includes a camera sensor 61 and a digital signal processor (DSP) 62 . For example, the camera sensor 61 is a megapixel CMOS sensor, records at a resolution of 1280×960 pixels, and is clocked according to a clock signal CK supplied from the DSP 12 at a frequency of about 48 MHz. 1 , providing an analog picture signal S composed of analog picture red, green and blue signals p . Since the structure of the camera sensor 61 is substantially the same as that of the camera sensor 11 shown in FIG. 2 , an explanation thereof is omitted.

[0039] As shown in FIG. 4 , DSP 62 includes ADC 71 , adjustment circuit 72 , external RAM controller 73 , encoder 74 , internal RAM 75 , RSPB 76 and FTB 77 . The DSP 62 operates with a clock signal of ...

Abstract

A camera-equipped mobile terminal includes an external memory (63) in a camera module. In a digital camera mode, image data (DP1) is temporarily buffered in the external memory (63). After this, during an empty time between processes in a resize processing section (76) and a format conversion section (77), an encoder (74) compresses / encodes the image data from the external memory (63) into image data (DP2) by time division and stores the data in the external memory (63). A CPU (53) acquires the image data (DP2) from the external memory (63) as is required. In a mobile camera mode, power of the external memory (63) is turned off. The image data (DP1) is temporarily buffered in an internal memory (75). After this, in the aforementioned empty time, the encoder (74) compresses / encodes the image data (DP1) from the internal memory (75) into the image data (DP2) by time division and stores the data in the internal memory (75). The CPU (53) acquires the image data (DP2) from the internal memory (75) as is required.

Description

technical field [0001] The present invention generally relates to a mobile terminal equipped with a camera, and more particularly, to a mobile terminal equipped with a camera capable of processing image data obtained by shooting with an attached camera so that the processed image The data is displayed on a display device, or the processed image data is transmitted in e-mail. Background technique [0002] FIG. 1 shows an example of necessary components of a conventional camera-equipped mobile terminal. The mobile terminal here is a general term including a mobile phone and a PHS (Personal Handyphone System). [0003] This example of a camera-equipped mobile terminal includes a camera module 1 , an interface 2 , a CPU (Central Processing Unit) 3 , a main LC board 4 and a sub-LC board 5 . [0004] The camera module 1 includes a camera sensor 11 and a digital signal processor (DSP) 12 . For example, the camera sensor 11 is a megapixel CMOS sensor, records at a resolution of 1...
