Publication number: 20180259647Abstract: An imaging device includes: a controller which generates a light emission signal and an exposure signal; a light source unit which receives the light emission signal and emits light; a light receiver which obtains the exposure amount of reflected light at a timing in accordance with the exposure signal; and a calculator which outputs a distance signal (distance image) by calculation on the basis of the amount of signals included in imaging signals received from the light receiver. The controller generates two or more patterns of varying phase relationships between the light emission signal and the exposure signal, and outputs the light emission signal and the exposure signal in a cycle that is different between at least two of the patterns.Type: ApplicationFiled: May 9, 2018Publication date: September 13, 2018Inventors: Haruka TAKANO, Tomohiko KANEMITSU, Tsuyoshi HASUKA, Mitsuhiko OTANI

Patent number: 7898589Abstract: A drive unit 120 sets a saturation amount in a read period in which charges generated in pixels are read to vertical CCDs to be lower in a combination mode than in an individual mode (see Vsub in count values 22 to 24 in FIG. 6). As a result, excess charges in the pixels are drained to an n-type substrate 11. The drive unit 120 also sets an accumulation period to be shorter in combination mode than in individual mode (see Vsub in each mode in FIG. 6).Type: GrantFiled: September 30, 2004Date of Patent: March 1, 2011Assignee: Panasonic CorporationInventors: Shinji Yamamoto, Toshiya Fujii, Kazuyuki Inokuma, Tsuyoshi Hasuka, Ryoichi Nagayoshi, Keijirou Itakura, Izumi Shimizu

Patent number: 7884872Abstract: A driving method is applied to a solid-state imaging apparatus having photoelectric conversion portions, transfer portion for reading out signal charges, and an excess charge draining portion for draining charges exceeding a saturation charge amount that is set by a reference voltage. One of driving modes is selected from a full pixel mode in which accumulated signal charges are detected individually for each pixel and a pixel mixing mode in which signal charges of a predetermined number of pixels are mixed to be detected. In the full pixel mode, the draining portion is supplied with the reference voltage having the same value during a charge accumulation period and a read transfer period for read transferring charges. In the pixel mixing mode, the draining portion is supplied with the reference voltage having a low level during the charge accumulation period and the reference voltage having a high level during the read transfer period.Type: GrantFiled: July 10, 2006Date of Patent: February 8, 2011Assignee: Panasonic CorporationInventors: Tsuyoshi Hasuka, Ryoichi Nagayoshi, Keijirou Itakura, Izumi Shimizu, Yoshiaki Kato

Publication number: 20100188536Abstract: The semiconductor element according to an aspect of the present invention is a solid-state imaging element formed on a semiconductor substrate, having an overflow drain structure for draining excessive charges generated in photoelectric conversion elements, and reading out signal charges accumulated in the photoelectric conversion elements to a vertical transfer unit via a readout gate electrode. The solid-state imaging element includes: a first voltage generating circuit which applies, to the semiconductor substrate, substrate voltage defining the height of overflow barrier in the overflow drain structure; and a second voltage generating circuit which selectively generates first voltage and second voltage each including the height of pulse wave superimposed onto the substrate voltage, at a time when readout pulse to be applied to the readout gate electrode is generated.Type: ApplicationFiled: July 9, 2008Publication date: July 29, 2010Applicant: PANASONIC CORPORATIONInventors: Tsuyoshi Hasuka, Toshihiro Kuriyama, Hiroyuki Mori, Junji Manabe

Patent number: 7719594Abstract: A solid-state imaging device, and a camera provided with this device, that can output high quality images at high speed are realized by preventing improper OB clamping in a solid-state imaging device that performs pixel mixing in the horizontal direction. Vertical final stages, which are the transfer stages closest to a horizontal transfer component 4, are provided with provided with independent transfer electrodes V3-1, V3-2, V3-3, V6-1, V5-2, and V5-3 that are independent of other columns in a region between the horizontal transfer component and an effective pixel region, and a common transfer electrode that is common to all of the columns in the region between the horizontal transfer component 4 and the OB region. Further, in the vertical final stages, the entire region between the OB region and the horizontal transfer component, or the region minus openings formed for the wiring of V3-1 and V5-1 in the columns closest to the effective pixel region, is covered with a light blocking film.Type: GrantFiled: September 20, 2006Date of Patent: May 18, 2010Assignee: Panasonic CorporationInventors: Yoshiaki Kato, Kazuya Yonemoto, Tsuyoshi Hasuka
