20090218804 | Photo album - An album includes a front cover panel, a back cover panel, and a spine panel extending between the front and the back cover panels edge-to-edge. A folding arrangement, which couples between a last album page and the back cover panel, includes a flexible sheet having two longitudinal edges coupling at an outer side of last album page and an inner side of the back cover panel to retain the last album page being overlapped on the back cover panel in a slidably movable manner. When the album is folded at an opened position, the front cover panel, the spine panel, and the back cover panel are aligned to form a planer backing for providing a completely plane on the surface of the album. | 09-03-2009 |
20090231829 | Lightwall instrument - A lightwall instrument for photographic purposes includes a supporting frame, a light source, a diffuser wall, and one or more shading walls. The position of the light source is adjustable. The shape of the diffuser wall is selectively changed for different effects. The present invention provides a convenient and flexible lightwall instrument for better effect of photographs or films. The light generated by the lightwall instrument is soft, even, and saturated. The effects are highly adjustable. The operation is easy. | 09-17-2009 |

20140263961 | PERFORMING SPATIAL & TEMPORAL IMAGE CONTRAST DETECTION IN PIXEL ARRAY - An imaging device has an array with pixels that can image an aspect of an object. In addition, pixels in the array can be used to perform motion detection or edge detection. A first and a second pixel can integrate light non-concurrently, and then their outputs may be compared. A difference in their outputs may indicate an edge in an imaging operation, and motion in a motion detection operation. The motion detection operation may be performed without needing the imaging device to have an additional modulated LED light source, and to spend the power to drive that source. | 09-18-2014 |
20140346361 | TIME-OF-FLIGHT PIXELS ALSO SENSING PROXIMITY AND/OR DETECTING MOTION IN IMAGING DEVICES & METHODS - An imaging device has a pixel array that includes one or more depth pixels. The imaging device also includes a controller that can cause one or more of the depth pixels to image a depth of an object in a ranging mode. The controller can further cause the depth pixel(s) to image in one or more detection modes, with the appropriate control signals. The imaging device also includes a monitoring circuit that can detect a current drawn by the depth pixel(s) in the detection modes. A revert indication can be generated from the detected current. Depending on the control signals, the revert indication can serve as a proximity indication, or as a motion indication. | 11-27-2014 |
20140347442 | RGBZ PIXEL ARRAYS, IMAGING DEVICES, CONTROLLERS & METHODS - A pixel array includes color pixels that have a layout, and depth pixels having a layout that starts from the layout of the color pixels. Photodiodes of adjacent depth pixels can be joined to form larger depth pixels, while still efficiently exploiting the layout of the color pixels. Moreover, some embodiments are constructed so as to enable freeze-frame shutter operation of the pixel array. | 11-27-2014 |
20140362260 | PIXEL ARRAYS & IMAGING DEVICES WITH REDUCED BLOOMING, CONTROLLERS & METHODS - A pixel array includes regular pixels for imaging, and special pixel sites interspersed among the regular pixels. When the regular pixels become saturated from bright illumination, at least some of their excess charges are removed by the special pixel sites. The removal can reduce or eliminate blooming. In some embodiments, the special pixel sites include special pixels. For imaging, the regular pixels of a group such as a sub-array provide regular outputs that are combined into a composite signal. The special pixels provide a special output. The special output of the group may optionally be added to the composite signal, which can increase the dynamic range. | 12-11-2014 |
20150036035 | RESET NOISE REDUCTION FOR PIXEL READOUT WITH PSEUDO CORRELATED DOUBLE SAMPLING - Provided are an imaging device implementing pseudo correlated double sampling (CDS), and an imaging method and a control method of the image device. The imaging device includes: a pixel array comprising a pixel configured to generate a current in response to incident light; a readout circuit configured to read out a plurality of output signals of the pixel, the plurality of output signals corresponding to a plurality of consecutive integration periods of the pixel within an aggregating period; and an aggregator configured to aggregate the plurality of output signals read out by the readout circuit to obtain a final aggregated output corresponding to illuminance for the aggregating period, wherein the readout circuit is configured to read out the plurality of output signals by, for each output signal, sampling a signal voltage of the pixel and sampling a subsequent reset voltage of the pixel and obtaining a difference therebetween. | 02-05-2015 |
20150054966 | IMAGING DEVICE USING PIXEL ARRAY TO SENSE AMBIENT LIGHT LEVEL & METHODS - Imaging devices and methods detect ambient light level using array pixels. In one embodiment, an imaging device includes an array of imaging pixels that are configured to acquire an image, and an array of dark pixels. A controller may cause at least one of the imaging pixels and of the dark pixels to image concurrently. A monitoring circuit may measure a difference between currents drawn by the imaging pixel and the dark pixel during the concurrent imaging. An indication of ambient light level can be generated according to the difference. The indication can be used as desired, for example to manage the brightness of the display screen. As such, no separate sensors are required, apart from the imaging array that is already provided for imaging. | 02-26-2015 |
