The image reading apparatus according to claim 1, wherein said image pick-up element groups correspond respectively to red, green and blue. 6. The image reading apparatus according to claim 1, wherein said image pick-up element rows in each of said groups consist of first and second element rows, and said second element row is shifted by a pitch of almost half of the width of one of said image pick-up elements relative to said first element row. 7. The image reading apparatus according to claim 1, wherein each of said image pick-up element groups has a shield portion defining a plurality of opening portions, each smaller than a light receiving area of a respective image pick-up element, to shield light from reaching onto a peripheral portion of the image pick-up element. 8. The image reading apparatus according to claim 1, wherein said image pick-up element rows in all of said groups are disposed on a common substrate. 9. A method of correcting an undesired level difference between data on adjacent pixels, which may occur in association with the use of plural image pick-up element rows to read single-color intensity information on one pixel on a line with an image pick-up element contained in an image pick-up element row and single-color intensity information on an adjacent pixel in the same line with an image pick-up element contained in another image pick-up element row, said method comprising the steps of: receiving intensity information on pixels on at least one line; comparing intensity information Kn+1 on a Kn+1-th pixel on said one line with a first predetermined value to determine whether the intensity information Kn+1 have a value indicative of a level brighter as an image than a predetermined level; outputting the intensity information Kn+1 as data for the Kn+1-th pixel if the intensity information Kn+1 have the value indicative of the level; calculating an absolute value |Kn-Kn+1| of a difference between the intensity information Kn+1 on the Kn+1-th pixel and intensity information Kn on a K-th pixel on the same line as the Kn+1-th pixel is located; comparing the absolute value |Kn-Kn+1| with a second predetermined value; outputting the intensity information Kn+1 as data for the Kn+1-th pixel if the intensity information Kn+1 do not have the value indicative of the level but the absolute value |Kn-Kn+1| is larger than the second predetermined value; and outputting corrected information as data for the Kn+1-th pixel if the intensity information Kn+1 do not have the value indicative of the level and the absolute value |Kn-Kn+1| is not larger than the second predetermined value. 10. The method according to claim 9, wherein said step of outputting corrected information includes calculating an average value based on the intensity information Kn+1 on the Kn+1-th pixel and the intensity information on the K-th pixel, and using the average value as the corrected information. 11. A system for correcting an undesired level difference between data on adjacent pixels, which may occur in association with the use of plural image pick-up element rows to read single-color intensity information on one pixel on a line with an image pick-up element contained in an image pick-up element row and single-color intensity information on an adjacent pixel in the same line with an image pick-up element contained in another image pick-up element row, said system comprising: a first circuit which receives intensity information on pixels on at least one line; a second circuit which compares intensity information Kn+1 on a Kn+1-th pixel on said one line with a first predetermined value to determine whether the intensity information Kn+1 have a value indicative of a level brighter as an image than a predetermined level; a third circuit whi
