Abstract: It is an object of this invention to reduce image sensing errors due to wrong white balance control using wrong color temperature information in an image sensing device capable of performing white balance control using a color image signal from an image sensing device. In order to attain the above object, when the color in the vicinity of the locus of a blackbody cannot be extracted in detection of a color temperature in a color image signal, color temperature information is corrected on the basis of a piece of color temperature information output from a calorimetric sensor, thereby controlling the white balance of a color image signal output from an image sensing element. The number of achromatic data extracted from the color image signal is counted. The color temperature is calculated by weighting a color temperature obtained from the color image signal and that obtained from the calorimetric sensor in accordance with the count, thereby performing white balance control.

The values may include those of a first pixel and each nearest neighboring pixel to the first pixel. A second pixel may have the highest value of the neighboring pixels. A third pixel may have the next highest value of the neighboring pixels. A first function may be performed on the second pixel value, producing a first output value.

Abstract: A high luminance point detecting section of an image processing apparatus detects a high luminance point of the captured image. A chroma extracting section sets a first area in the captured image with the high luminance point serving as a reference point and extracts a first chroma by using color information of the first area. Further, the chroma extracting section sets a second area at a position more apart from the high luminance point than the first area in the captured image and extracts a second chroma by using color information of the second area. A color bleeding estimating section estimates intensity of color bleeding appearing in the captured image based on a value of the first chroma relative to the second chroma.

Abstract: A system and method provide interactive techniques for sharing digital photos, in which a user of a portable electronic device may seek out a location at which another electronic device was used to capture a photo. The captured image may then be displayed on a display of the user's electronic device by superimposing the photo on the display while the display functions as an electronic viewfinder for a camera assembly of the electronic device. The viewing of another person's photos is made to be an interactive and entertaining experience. The disclosed techniques combine the user's “real world” presence (e.g., location and viewing perspective) with the previously captured photo to create a fun and exciting experience that also may serve as a trigger for communication between the user and the person who took the photo.

Abstract: A smart camera device incorporates a first processing path for video display processing and a second processing path for detection and/or tracking processing. A sensor device provides input signals including first size data units to both processing paths, at least some of the same input signals are processed by both processing paths. The video display processing generates second size data units which are smaller than first size data units. First size data units provide more information to the detection/processing module than second size data units would have provided if used. IR detection capability is improved by using first size data units. Detection and/or target tracking operations generate control signals used to control the video display processing to enhance the visual perceptibility of a detected target.
