Digital camera with a music playback function

Abstract: A digital camera, which includes: an image playback module; and a music playback module, wherein a plurality of images are played back accompanied by music, an image playback time for the plurality of images substantially coincides with a music playback time for the music, and the image playback time is defined based on a number of the images and a playback time for each of the images, when sequentially playing back the plurality of images

System and method for controlling a camera based on processing an image captured by other camera

Abstract: A device comprises a first digital camera having a first center line of sight and a second digital camera having a second center line of sight that is parallel and opposing the first camera. A method for controlling the first camera based on estimating the angular deviation between a person gaze direction and the line of sight of the first digital camera. A human face is detected in an image captured as an image file by the second digital camera, using a face detection algorithm. An angular deviation α is estimated, defined between the second center line of sight and an imaginary line from the second camera to the detected human face based on the captured image, and an angular deviation β is estimated, defined between the imaginary line from the second camera to the detected face and the human face gaze direction based on the captured image.

Digital camera with an automatic image transmission function

Abstract: A digital camera with an automatic image transmission function which includes a transmission section for transmitting photo images and a transmission control unit connected to the transmission section. The transmission control unit judges whether a predetermined transmission allowance condition is satisfied and allows the transmission of photo images only when the predetermined transmission allowance condition is satisfied. As one example, the predetermined transmission allowance condition includes a condition when photography is completed.

Distance measurement based on pixel variation of CCD images.

Abstract: This paper presents a distance measurement method based on pixel number variation of CCD images by referencing to two arbitrarily designated points in the image frames. By establishing a relationship between the displacement of the camera movement along the photographing direction and the difference in pixel count between reference points in the images, the distance from an object can be calculated via the proposed method. To integrate the measuring functions into digital cameras, a circuit design implementing the proposed measuring system in selecting reference points, measuring distance, and displaying measurement results on CCD panel of the digital camera is proposed in this paper. In comparison to pattern recognition or image analysis methods, the proposed measuring approach is simple and straightforward for practical implementation into digital cameras. To validate the performance of the proposed method, measurement results using the proposed method and ultrasonic rangefinders are also presented in this paper.

Digital camera, digital photographic system, and image transmission method using the digital photographic system

Abstract: A digital camera is characterized by displaying an alarm in a display device in its finder, in the case where it cannot communicate with receivable equipment located nearby, or there is no receivable equipment located nearby.
