20110038623 | Camera - A camera includes: a first sensor of a storage type that has a plurality of pixels; a focus detection unit that detects a focus adjustment state of a photographic optical system based upon a detection signal from the first sensor for a photographic subject; a second sensor that acquires an image of the photographic subject; an extraction unit that extracts a main photographic subject region from image information acquired by the second sensor; and a control unit that controls accumulation of electrical charge by the first sensor, based upon values outputted from pixels of the first sensor that correspond to the main photographic subject region. | 02-17-2011 |
20110052168 | FOCUS DETECTION APPARATUS AND FOCUS DETECTION METHOD - An apparatus includes a monitor unit configured to monitor and output an accumulation state of a monitor area, which is apart of the detection area, a control unit configured to start an accumulation for focus adjustment in a detection area, and to determine whether the accumulation is ended based on the accumulation state, and to end the accumulation, when it is determined that the accumulation is to be ended, and an adjusting unit configured to use, for a focus adjustment, an output signal in a first area including the monitor area in priority to an output signal in a second area not including the monitor area. | 03-03-2011 |
20110286734 | Camera - A camera includes: a first sensor of a storage type that has a plurality of pixels; a focus detection unit that detects a focus adjustment state of a photographic optical system based upon a detection signal from the first sensor for a photographic subject; a second sensor that acquires an image of the photographic subject; an extraction unit that extracts a main photographic subject region from image information acquired by the second sensor; and a control unit that controls accumulation of electrical charge by the first sensor, based upon values outputted from pixels of the first sensor that correspond to the main photographic subject region. | 11-24-2011 |
20130121676 | CAMERA AUTOFOCUS APPARATUS AND ASSOCIATED METHOD - An apparatus, and an associated method, facilitates performance of an autofocus procedure of a camera device that has variable focus capabilities. Indications of an autofocus-actuator stability time indication are provided. And, a determination is made as to whether the provided indication is of a time length greater than a frame length. If so, a blank period is appended to a frame. The length of the blank period is selected so that the time period associated with the obtained time indication is no greater than the frame period. | 05-16-2013 |
20130202281 | FOCUS DETECTION APPARATUS AND METHOD FOR CONTROLLING THE SAME - A focus detection apparatus that performs a first determination for determining whether a signal level indicating an amount of the electric charges accumulated in the photoelectric conversion element has reached a lower threshold, and a second determination for determining whether the signal level has reached a higher second. During a time period from when it is determined that the signal level has reached the lower threshold to when it is determined that the signal level has reached the higher threshold, the second determination is performed at a shorter time interval if an elapsed time from when the accumulation of the electric charges is started to when it is determined that the signal level has reached the first threshold is shorter than a reference time, and at a longer time interval if the elapsed time is longer than the reference time. | 08-08-2013 |
