20090059024 | IMAGE PICKUP CIRCUIT - An image pickup circuit includes a plurality of circuit blocks. Each of the plurality of circuit blocks includes a plurality of comparing elements, a single counter, and a plurality of storage units. Each of the comparing elements compares a pixel signal supplied through a vertical signal line connected to vertically aligned pixels in a plurality of pixels arranged in a matrix, and a slope signal whose voltage is changed from an initial voltage at a constant slope. The counter counts an elapsed time since a voltage of the slope signal starts to change from the initial voltage. Each of the storage units stores a count value obtained by the counter in accordance with a comparison result of the comparator, the count value corresponding to an elapsed time until the voltage of the slope signal is changed from the initial voltage to a voltage coinciding with the pixel signal. | 03-05-2009 |

When the user has selected the album search, message “By Title ?” which prompts the user to select album title name search is displayed. When the user has selected the title name search, message “Keyword IN” which prompts the user to input a key word is displayed. When the user has input key word “P” for the search, the HD recording and reproducing device | 02-11-2010 |
20100253560 | Electronic apparatus, AD converter, and AD conversion method - An electronic apparatus includes: an AD conversion section that has a comparing section, which receives a reference signal whose level changes gradually from a reference signal generating section that generates the reference signal and which compares the reference signal with an analog signal to be processed, and a counter section, which receives a count clock for AD conversion and performs a count operation on the basis of a comparison result of the comparing section, and that acquires digital data of the signal to be processed on the basis of output data of the counter section; a count operation period control section that controls an operation period of the counter section in each processing period on the basis of the comparison result of the comparing section; and a driving control section that controls the reference signal generating section and the AD conversion section. | 10-07-2010 |
20110062310 | SOLID-STATE IMAGING DEVICE, IMAGING DEVICE AND DRIVING METHOD OF SOLID-STATE IMAGING DEVICE - It is possible to achieve compatibility between suppressing dark current caused by a leak phenomenon and ensuring element reliability in a CMOS solid-state imaging device. When a pixel using electrons as signal charge is driven, the negative voltage level of each of control signals adapted to pulse-drive transistors in the pixel is adjusted so that the longer the charge accumulation time, the higher the voltage level. Preferably, the negative voltage level is grounded (GND) when no signal charge is accumulated. The negative voltage level is increased only when the charge accumulation time is long, which is the case where dark current caused by a leak phenomenon becomes a problem. Therefore, it is possible to suppress stress on the pixels and the gate oxide film of their drive circuits and degradation of the transistor characteristics even if dark current is suppressed. | 03-17-2011 |

20140101705 | INFORMATION-PROVISION CONTROL METHOD, INFORMATION REPRODUCTION SYSTEM, INFORMATION-PROVISION APPARATUS, INFORMATION REPRODUCTION APPARATUS AND INFORMATION-PRESENTATION CONTROL PROGRAM - When the information-provision apparatus is providing an audio signal to the specific information reproduction apparatus, the user enters an operation input to the specific information reproduction apparatus to switch processing to reproduce an audio content from the specific information reproduction apparatus to another information reproduction apparatus. In this case, the specific information reproduction apparatus requests the information-provision apparatus to start an operation of providing the audio content to the other information reproduction apparatus specified in the operation input as an apparatus to newly reproduce the audio content. Then, the specific information reproduction apparatus requests the information-provision apparatus to end an operation of providing the audio content to the specific information reproduction apparatus specified in the operation input as an apparatus to terminate an operation of reproducing the audio content. | 04-10-2014 |
