Abstract

An image processor which forms a composite image of at least two images includes a storage unit which stores first and second image data, and a display unit which reads and displays the stored first and second image data in modes adapted to display forms of the first and second image data. The image processor also includes an image-signal forming unit which forms image signals representing a composite image of the stored first and second image data for display on a television monitor and a liquid crystal display panel.

Claims

1. A digital camera comprising:

an image capture unit;

a memory unit configured to store a captured image, captured by said image capture unit, and character data that overlaps with the captured image;

a display unit;

a signal output unit configured to output a first superimposed image to an external device;

a first superimposing unit configured to output the first superimposed image to the external device, through said signal output unit, by superimposing the captured image and the character data read out from said memory unit; and

a second superimposing unit configured to output a second superimposed image to said display unit by superimposing the captured image and the character data read out from said memory unit,

wherein said first superimposing unit and said second superimposing unit superimpose the captured image and the character data without rotation, when the captured image is captured without inclining the digital camera, and

wherein said first superimposing unit generates the first superimposed image by rotating the captured image and not rotating the character data, when the captured image is captured with the digital camera in the vertical position, and

wherein said second superimposing unit generates the second superimposed image by rotating the character data and not rotating the captured image, when the captured image is captured with the digital camera in the vertical position.

2. The digital camera according to claim 1, wherein the rotation of the image or the character data is performed in units of 90 degrees.

3. The digital camera according to claim 1, wherein the external device is a display unit.

4. A method for use in a digital camera including an image capture unit, a memory unit adapted to store a captured image captured by the image capture unit and character data that overlaps with the captured image, a display unit, a signal output unit configured to output a first superimposed image to an external device, a first superimposing unit configured to output the first superimposed image to the external device through the signal output unit and, a second superimposing unit configured to output a second superimposed image to the display unit, the method comprising the steps of:

capturing an image with the image capture unit;

storing the captured image and the character data in the memory unit;

outputting a first superimposed image to the external device, through the signal output unit, by superimposing the captured image and the character data read out from the memory unit;

outputting a second superimposed image to the display unit by superimposing the captured image and the character data read out from the memory unit;

wherein the first superimposed image and the second superimposed image are superimposed without rotating the captured image or the character data, when the captured image is captured without inclining the digital camera, and

wherein the first superimposed image is superimposed by rotating the captured image and not rotating the character data, when the captured image is captured with the digital camera in the vertical position, and

wherein the second superimposed image is superimposed by rotating the character data and not rotating the captured image, when the captured image is captured with the digital in the vertical position.
