A camera system may include an image sensor to generate real-time image data of a scene having a subject. A pose evaluator can generate a pose metric signal having a pose value that provides a variable measure of a pose quality for the subject in the scene. A pose feedback indicator can provide user-perceptible feedback demonstrating the value of the pose metric signal, such that the variable measure of the pose quality is provided.

Systems and methods of smile detection are disclosed. An exemplary method comprises generating a search map () for a subset of an image (). The method also comprises identifying a plurality of candidates (-) representing mouth corners. The method also comprises generating parabolas () between each pair of candidates representing mouth corners. The method also comprises analyzing contour of at least one of the parabolas to determine whether the mouth curves substantially upward to form a smile or curves substantially downward to form a frown.

Smile detection systems and methods

A device to apply detection schemes to texture information of a face detected within an image to generate mouth corner candidates and identify best matching mouth corners by applying a geometric model to the moth corner candidates.

Mouth corner candidates

An image contains a representation of a person's face, where the image has plural points each comprising multiple components of a color space. For each of the plural points, at least two of the color space components are combined to produce a respective aggregate value. The image is processed to convert at least some of the points of the image based on the calculated aggregate values.

When a digital camera detects that it has been placed in a demo dock, it resets internal settings to demo defaults and may launch a point-of-purchase dock demo to attract attention. When a customer removes the camera from the demo dock, an interactive demo may begin. The demo may instruct the customer how to interact with the demo or end it. Once ended, the camera reverts to normal operation until replaced in the demo dock. Methods of using the dock and digital camera are also disclosed.

A method for correcting white balance in a captured digital image includes storing raw sensor data representative of the captured digital image in a memory and normalizing the raw sensor data by applying an illuminant-independent shading and vignetting correction to the raw sensor data. The method continues with applying a plurality of illuminant-dependent shading and vignetting correction masks to the raw sensor data and comparing the illuminant-dependent shading and vignetting correction result with the illuminant-independent shading and vignetting correction result.

White balance correction in a captured digital image

A method for determining an illuminant in a scene includes, applying, to sampled outputs of a sensor array used to capture the scene, a plurality of color-correction profiles, wherein each color-correction profile corresponds to a particular illuminant, thereby forming a plurality of color-corrected sampled outputs. The method further includes identifying the illuminant in the scene as corresponding to the color-corrected sampled output having the least color variance.

Determining the illuminant in a captured scene

A digital imaging device produces and stores multiple video streams from a single imaging sensor array. The stored video streams may be post-processed using video editing software to create a combined video presentation.

A method and device for adjusting white balance are disclosed herein. The method may comprise generating data representative of an image with and without the use of a strobe. The contribution of the strobe and the contribution of ambient light are on the data are calculated. Based, in part, on the contributions of the ambient light and the strobe, a weight is calculated. The weight is applied to the data in order to adjust the white balance.

Method and device for adjusting white balance

The shutter of a digital imaging device may be calibrated by comparing a characteristic of two separate exposures obtained from a single field of the device's imaging sensor during a single exposure cycle. Calibrating the shutter in this manner facilitates the accuracy of even very short exposure times.

Digital imaging device shutter calibration method and apparatus using multiple exposures of a single field

A digital imaging device having a CCD sensor array with one or more fields captures both short and long exposures of a particular field during the capture of a single image frame. The short-exposure image data and the long-exposure image data from the particular field may be correlated to estimate motion within the image frame.

The present invention provides a system and method for compensating captured images. Briefly described, one embodiment comprises white balance compensating a strobed image data and a nonstrobed image data using a first white balance compensation value corresponding to supplemental illumination provided by a supplemental illumination source, determining a difference between the strobed image data compensated with the first white balance compensation value and the nonstrobed image data compensated with the first white balance compensation value, white balance compensating the nonstrobed image data using a second white balance compensation value corresponding to ambient light, and combining the difference to the nonstrobed image white balance compensated using the second white balance compensation value.

System and method for dual white balance compensation of images

An appliance is provided for capturing and communicating images to other devices with communication capabilities. An embodiment of the appliance comprises capturing a plurality of image data, grouping the image data into a group, receiving new image data, and attaching the new image data to the group such that the group comprises the plurality of image data and the new image data.

Appliance and method for communicating and viewing multiple captured images

Viewfinder apparatus, methods, and digital cameras that provide autofocus using retroreflected eye focus measurements. When a user looks at a part of a scene that is the intended subject of the image, his or her eye is correctly focused. The present invention measures the focus distance of the eye when the eye is focused on the desired location in the scene, and then uses the measured distance to set the focus of the camera.

Digital camera autofocus using eye focus measurement

Disclosed are systems and methods for facilitating composition of handwritten documents. In one embodiment, a system and method pertain to identifying handwritten input entered in a display of a computing device, and controlling the placement of handwritten input on the display so as to enable uninterrupted handwriting on the display.
